Abstract
Description
Technical Field
[0001] This utility model specifically relates to a mobile device for calf farming, belonging to the technical field of calf transport equipment. Background Technology
[0002] In the current dairy farming industry, the main method of calf rearing is outdoor individual pen rearing. However, since the breeding season for dairy cows is generally in autumn and winter, how to enhance the survival rate of calves and reduce the impact of the environment and human factors on calf survival has become an urgent problem to be solved in the dairy farming industry. Existing solutions generally involve transferring calves to indoor rearing using transfer equipment. Existing transfer equipment, such as the newborn calf transfer vehicle disclosed in Chinese Patent Publication No.: CN220785576U, includes a transfer box, a mobile power supply, heating equipment, drying equipment, air purification equipment, and excrement collection equipment. Most of these devices use heating and drying equipment to keep the calves warm, and air purification and excrement collection equipment to keep the air inside the transfer box clean. Existing transfer equipment is all integrated in structure, which cannot be quickly disassembled and assembled, and is not convenient to store. During the transfer process, it needs to be locked manually. If it is not locked, if the cow breaks open the door, it may be injured. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes a mobile device for calf farming that is easy to use and store, reducing manual handling of calves from birth to individual pen rearing, thereby minimizing injury to the cattle and reducing human-animal contact during manual handling.
[0004] The mobile device for calf farming of this utility model includes:
[0005] The retractable unit includes multiple sets of retractable units. Each retractable unit includes two frame beams facing each other, with a transfer wheel fixed to the bottom of each frame beam. A PVC retractable plate is retractable between the frame beams, and an automatic locking device is installed at one end between the frame beams and the PVC retractable plate.
[0006] Calf stall, the calf stall is directly opposite the side of the frame beam fixed to two adjacent pull-out units, and the calf stall has a head passage opening;
[0007] A feeding bucket, which is fixed to the calf pen and positioned below the head opening;
[0008] The base plate includes a floor support fixed to the bottom of the pull-out unit, and a manure-slip floor is laid on the floor support.
[0009] A PVC middle partition is fixed to the top surface of the slatted floor and movably attached to the middle of two adjacent PVC pull-out panels.
[0010] During transport, the PVC pull-out panel is unlocked by an automatic locking device and pulled out from the frame beam. Then, the calf is placed into the enclosure formed by the bottom plate, the PVC middle partition, the PVC pull-out panel, and the calf pen. Next, the PVC pull-out panel is put back into the frame beam, and the position of the PVC pull-out panel is automatically locked by the automatic locking device. Finally, the calf is transported by transport wheels. During the transport, the calf can be fed through a feeding bucket.
[0011] The slatted floor, PVC pull-out panels, and PVC partitions are all made of plastic, which is safe, non-toxic, durable, and highly malleable. It also has a certain degree of impact resistance to prevent damage from overly active calves. The transfer wheels consist of a combination of directional wheels and brake casters, and are made of rubber, facilitating fast and safe transport of cattle during disinfection, quarantine, health checks, and pen separation. The feeding buckets, calf pens, and automatic ramming devices are made of stainless steel, effectively reducing corrosion from cattle excrement and disinfectants. The automatic ramming devices prevent cattle from accidentally breaking through the doors and falling and getting injured.
[0012] Furthermore, a partition gripper is fixed to the end of the PVC pull-out panel, which can drive the PVC pull-out panel to slide between the two frame beams.
[0013] Furthermore, the automatic lock includes a bracket fixed to the frame beam and a locking pin fixed to the side of the PVC pull-out plate; the bracket has a sliding groove on its side; a cam-shaped claw is hinged to the inner side of the bracket; the bottom of the claw can fit against the bottom of the inner side of the sliding groove; the locking pin is slidably installed with the sliding groove, and the locking pin is movably engaged with the claw; when the automatic lock is working, it pushes the PVC pull-out plate to slide between the two frame beams. During the sliding, the locking pin slides in the sliding groove and passes through the claw. At this time, the claw automatically limits the locking pin, realizing the automatic locking of the automatic lock. At this time, the locking pin is restricted by the claw, and the PVC pull-out plate cannot move backward. When unlocking is required, the top of the claw needs to be pressed down. At this time, the locking pin can pass through the claw smoothly; at this time, the PVC pull-out plate can be pulled out smoothly.
[0014] Furthermore, the floor support includes a crossbeam fixed to the bottom of the inner side of two frame beams of the pull-out unit; multiple longitudinal beams are fixed to the top of the crossbeam; a slatted floor is laid on the longitudinal beam; the crossbeam and longitudinal beam form a support structure for the bottom of the mobile device, and the slatted floor is supported by the crossbeam and longitudinal beam.
[0015] Furthermore, the pull-out unit is provided in three sets, forming a grid-shaped compartment, with each compartment capable of accommodating one calf.
[0016] Compared with existing technologies, the mobile equipment for calf farming of this utility model adopts a modular design, which can be quickly disassembled and assembled, and is convenient to use and store. The slatted floor, PVC pull-out board and PVC middle partition are made of polyethylene, which can effectively ensure convenient cleaning and disinfection and prevent calf injury. The feeding bucket, calf pen board and automatic ramming device are made of stainless steel, which can greatly improve the corrosion resistance and structural strength of the product and meet market demand.
