TECHNICAL FIELD

The present application relates to the field of automation equipment, and in particular, to a vaccine spray equipment.

BACKGROUND

Coccidiosis is a very serious global parasitic disease that causes huge economic losses to the chicken industry every year. At present, anti-coccidiosis mainly depends on adding anti-coccidiosis drugs in feed or drinking water, or using coccidiosis vaccine to prevent chicken coccidiosis. Chicken coccidiosis vaccine immunization methods include drinking water, mixing (spraying) materials, dripping, spraying, and the like. At present, the main popular immunization method is drinking water immunization. After the coccidiosis vaccine and the suspending agent are mixed uniformly and put into a drinking water bottle for chicks to drink to obtain immunity. The drinking water immunization is easier to operate than methods such as mixing and dripping immunization. However, there are certain limitations in the scope of application of drinking water immunization, especially in large-scale intensive chicken farms, due to the small number of breeders, it is not suitable to use drinking water with a large workload for immunization.

In the related art, spray immunization is to dilute the vaccine and spray the vaccine through a spray equipment. The chicks can be immunized after the vaccine passes through the respiratory tract or is freely pecked. However, the spray equipment sprays small droplets, the vaccine liquid attached to the feathers is easy to evaporate and affect the pecking of chickens, and some of the droplets are suspended in the air, causing waste, and the coccidiosis vaccine must be immunized by mouth. Therefore, in the related art, the spray immunization method and equipment do not enable chicks to obtain effective anti-coccidiosis immunity.

Currently, there is a vaccine spray equipment that uses spray needles to spray vaccine suspension liquid on chicks, and attaches the vaccine suspension liquid of suitable size to the feathers for the chicks to eat. When there are no gaps or small gaps between the chick frames continuously in the equipment, the front end of the alternate chick frame could not spray liquid through the spray head, because the pump had not fully absorbed the liquid and returned to the original position.

DETAILED DESCRIPTION

As shown inFIGS. 1 to 3, this embodiment provides a vaccine spray equipment, which is configured to spray vaccine suspension liquid on the chicks in the chick frame100. The vaccine spray equipment includes a frame1, a conveying device, a spray device3and two liquid supply devices. The conveying device is disposed on the frame1, and is configured to support and convey the chick frame100, and the spray device3is disposed on the frame1. The spray device3includes two rows of spray heads disposed along the conveying direction perpendicular to the conveying device. The two rows of spray heads31are provided side by side above the conveying device. The two liquid supply devices are disposed on the frame1, and respectively communicate with the two rows of spray heads31in a one-to-one correspondence. The liquid supply devices are configured to provide the spray device3with a vaccine suspension liquid.

Illustratively, each row of spray heads31on the vaccine spray equipment is supplied with vaccine suspension liquid by a separate liquid supply device. When the conveying device drives the chick frame100with chicks to pass under the spray device3, the two rows of the spray heads31work alternately or synchronously and intermittently to ensure that the vaccine suspension liquid sprayed by the spray device3covers all the chicks in each chick frame100which improves the effect of vaccine spraying, and at the same time to avoid the situation that the conveying device needs to be repeatedly paused due to the single-row spray heads31to wait for the liquid supply device to re-absorb liquid, thereby improving the efficiency and continuity of vaccine spraying.

Optionally, the liquid supply device includes a liquid storage tank45, a pumping servo motor41, and a pumping piston42, the liquid storage tank45is configured to store vaccine suspension liquid, and the pumping servo motor41is installed on the frame1.

Optionally, the pumping piston42is in driving connection to the pumping servo motor41by a ball screw mechanism.

Illustratively, when one row of spray heads31sprays, the pumping piston42connected to another row of spray heads31returns to its position and sucked up the vaccine suspension liquid. When the row of spray heads31to be sprayed has finished spraying to the chicks in the chick frame, the chicks in another chick frame is to be transported to the spraying position, and another row of spray heads31can spray the vaccine suspension liquid, which eliminates the time to wait for the pumping piston42to return to its position to absorb the liquid. The chick frame100can continuously pass through the spray head31to improve the spray efficiency. At this time, the spray head31sprays 25 ml-40 ml at a time.

Alternatively, the distance between the two rows of spray heads31is half the length of the chick frame100, and the chick frame100continuously passes through the spray heads31. When the chick frame100travels a half of the length of the chick frame100, the two rows of the spray heads31starts spraying liquid synchronously. After the chick frame100travels another half of the length of the chick frame100, the two rows of spray heads31synchronously stop spraying liquid, and the cycle repeats, in this way, each chick frame100can accept the spraying of the two rows of the spray heads31, and ensure that the vaccine suspension liquid sprayed by the spray device3covers all the chicks in each chick frame100. At this time, the spray volume of each row of the spray heads31is 12.5 ml-20 ml.
