Description

Technical Field

[0001] The present invention belongs to the technical field of livestock breeding devices, and particularly relates to a feces cleaning device for elevated livestock houses. Background Art

[0002] At present, the commonly used equipment for cleaning feces in elevated livestock houses is a manure scraper or a conveyor belt. These devices are fixed under the livestock beds, with a harsh working environment, easy to corrode, frequent failures, and high maintenance costs; each livestock house needs to be equipped with such devices, resulting in a large investment; and they need to operate regularly every day, requiring manual attendance, which is time-consuming and laborious. Some elevated livestock houses adopt manual feces cleaning, generally once every 3 - 6 months, which greatly reduces the daily man-hour input and mechanical wear, but the centralized feces cleaning work is heavy, and even the breeding bed rails need to be disassembled to clean thoroughly, with low work efficiency and high operation costs. Therefore, it is urgently needed to be improved. Summary of the Invention

[0003] The purpose of the present invention is to provide a feces cleaning device for elevated livestock houses, which can be moved by mechanical traction or manually, is convenient to operate, has a large feces scooping depth, a wide adaptation range, high work efficiency, and is easy to maintain; only one machine can meet the needs of the whole farm, with relatively low equipment investment; in addition, when working, there is no need to disassemble the breeding bed rails, which helps to reduce the operation costs.

[0004] The present invention adopts the following technical solutions:

[0005] A feces cleaning device for elevated livestock houses includes a manure scooping cart, and the manure scooping cart includes a cart body, a cart body shaft, a ground gripping wheel, a wheel shaft, a limit connecting block, and a frame; the front of the cart body is in an arc-shaped groove structure, and the lower opening is in a blade shape. The back of the cart body is rotatably connected to the cart body shaft through a connecting member. The cart body shaft is horizontally arranged. The top of the limit connecting block is fixedly connected to the cart body shaft, and the front end is fixedly connected to the wheel shaft. An arc-shaped surface matching the cart body is provided on the side of the limit connecting block close to the cart body. The frame includes a connecting plate. One side of the connecting plate is provided with a push rod, and the other side is respectively fixed with a connecting arm at both ends. The two connecting arms are arranged in parallel.

[0007] Preferably, the feces cleaning device further includes a walking platform, a pushing and pulling power device, an adjustable support, and a laser sight; the push rod is a rack push rod, which includes a front push rod and a rear push rod. The front push rod and the rear push rod are hinged through a movable connection buckle. Rack teeth are provided at the rear end of the bottom of the front push rod and the entire bottom of the rear push rod. The pushing and pulling power device includes a transmission gear, and the transmission gear is meshed and connected with the rack teeth. The front end of the front push rod passes through the adjustable support and is connected to the connecting plate; the pushing and pulling power device is fixed in the middle of the rear end of the walking platform and is used to drive the rack push rod to move back and forth; the adjustable support is connected in the middle of the front end of the walking platform and is used to adjust the lifting height of the rack push rod; the laser sight is arranged on the walking platform and is used to emit rays to provide a reference benchmark for the position adjustment of the walking platform. Through the walking platform, the overall movement of the device is facilitated. Through the pushing and pulling power device, driving force is provided for the rack push rod, thereby driving the manure truck to move back and forth to complete the manure removal operation. By hinging the front push rod and the rear push rod through a movable connection buckle, it is convenient to fold the rack push rod according to the site needs for the flexible movement of the device. By setting the adjustable support to adjust the lifting height of the rack push rod, the height of the manure truck can be adjusted conveniently. The laser sight can be used to aim at or avoid obstacles during the movement of the device.

[0008] Preferably, the pushing and pulling power device further includes a reduction motor, a pressing wheel, a motor speed and rotation direction controller, a travel switch, and a support frame. The support frame is fixed on the walking platform.

A crank is arranged at the top of the adjusting bolt. The front end of the front push rod supports above the lower roller and is slidably connected between the left roller and the right roller to ensure that the manure truck moves in a straight line. By rotating the adjusting bolt with the crank, the height of each roller can be adjusted, and thus the height of the manure truck is adjusted to prevent the manure truck from touching the ground after being pulled out of the livestock house. Moreover, it is used to adjust the lifting height of the manure truck when the whole device is moving to adapt to the height difference inside and outside different livestock houses.

[0011] Preferably, a laser sight bracket or a push handle is arranged on the side of the walking platform. The laser sight is connected to the laser sight bracket or the push handle through a fixing clip. The laser sight includes a gravity vertical block, a laser lamp and a laser lamp switch.
