[0002] In large-scale farms, it is necessary to measure the weight of the animals regularly, which is helpful for farmers to detect the growth of the animals and make targeted adjustments. For large livestock, since their weight can generally reach hundreds of kilograms, they are generally weighed on a floor scale. When measuring, these livestock are driven onto the scale one by one to measure their weight.

[0003] Since the time for livestock to urinate and defecate is not restricted, for large farms, since there are many large livestock that need to be weighed, it is inevitable that some livestock will defecate and urinate on the scale. These feces and urine accumulate on the scale and cause corrosion to the scale. Summary of the invention

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0020] See also Figures 1 to 3 The large livestock scale comprises a scale body 1, a cleaning device 2 and a flushing device 3. Large livestock stand on the scale body 1 to weigh their weight. If they defecate or urinate on the scale body 1, the cleaning device 2 is used to clean the feces and urine on the scale body 1, and the flushing device 3 is used to clean the cleaning device 2.

[0021] The scale body 1 includes a weighing part 11, a weighing surface part 12, a sloped surface part 13 and a waterproof seat 14. The weighing part 11 is a functional part of the scale body 1, including the electrical and mechanical structures necessary for completing the weighing operation. When large livestock or other items are placed on the weighing part 11, the weighing part 11 can display its weight. The weighing part 11 adopts the conventional structure of a floor scale, which is common knowledge in the art and will not be described here.

[0022] The scale surface portion 12 is a plane, the slope surface portion 13 surrounds the scale surface portion 12 and the upper end is fixedly connected to the edge of the scale surface portion 12, and the lower end is inclined in the direction away from the scale surface portion 12, and the scale surface portion 12 and the slope surface portion 13 together form a cover arranged above the weighing portion 11, wherein the scale surface portion 12 is arranged directly above the weighing portion 11 and is in contact with the weighing portion 11, and the slope surface portion 13 surrounds the weighing portion 11 to play a protective role.

[0023] The weighing part 11 is placed on a waterproof seat 14, which includes a support leg, a carrier plate and a surrounding plate. The upper end of the support leg is fixedly connected to the lower surface of the carrier plate, and the lower end is placed or fixed on the ground, so that the carrier plate is suspended from the bottom surface. The lower end of the surrounding plate is fixedly connected to the upper surface of the carrier plate, and the surrounding plates are enclosed to form a waterproof area, and the weighing part 11 is arranged in the waterproof area.

[0024] When large livestock are weighed, they are first driven onto the scale surface 12 one by one, and the slope surface 13 also allows large livestock to more easily walk onto the scale surface 12. When large livestock urinate or defecate on the scale surface 12, the cleaning device 2 is used to clean them, and the generated sewage flows from the slope surface 13 to the ground without contacting the weighing part 11.

[0025] The cleaning device 2 includes a displacement mechanism 21, a shovel plate 22, a flushing mechanism 23 and a brush 24. The displacement mechanism 21 is arranged on one side of the scale face portion 12 and faces the scale face portion 12, generally perpendicular to the direction in which large livestock are traveling. The moving end of the displacement mechanism 21 is fixedly connected to the shovel plate 22, the flushing mechanism 23 and the brush 24, and can drive the shovel plate 22, the flushing mechanism 23 and the brush 24 to reciprocate toward the scale face portion 12 to clean the feces and urine on the scale face portion 12. In this embodiment, the displacement mechanism 21 can be a cylinder because the load is not large.

[0026] Along the direction toward the scale body 1, the shovel plate 22, the flushing mechanism 23 and the brush 24 are arranged in sequence, and the lower end of the shovel plate 22 is bent to form a shovel surface and abuts against the upper surface of the scale face portion 12 to shovel away feces and urine on the scale face portion 12. In this embodiment, the length of the shovel plate 22 is not less than the length of the scale face portion 12, so that the shovel plate 22 can fully shovel the entire scale face portion 12 under the drive of the displacement mechanism 21 without leaving a dead angle.

[0027] The flushing mechanism 23 includes a first nozzle and a first water supply hose. One end of the first water supply hose is connected to the external water supply device and the other end is connected to the water inlet end of the first nozzle. The water outlet end of the first nozzle is tilted downward and toward the direction of the shovel plate 22 to flush the upper surface of the scale face portion 12. Therefore, in this embodiment, it is preferred to arrange a row of flushing mechanisms 23 along the direction in which the shovel plate 22 extends, so as to fully flush the upper surface of the scale face portion 12. Preferably, in order to save water, the water supply switch of the external water supply device can also be bound to the displacement mechanism 21, and water is only supplied when the displacement mechanism 21 starts to work.

[0028] The scraper brush 24 is similar to the shovel plate 22 , and its length should be not less than the length of the scale face portion 12 . The bristles of the shovel plate 22 can abut against the upper surface of the scale face portion 12 for cleaning the upper surface of the scale face portion 12 .

[0029] The flushing device 3 is disposed on the other side of the scale surface 12 opposite to the cleaning device 2 , that is, the displacement mechanism 21 pushes the shovel plate 22 , the flushing mechanism 23 and the brush 24 to reciprocate toward the flushing device 3 .

[0030] When the shovel board 22 pushes out the feces produced by the excretion of large livestock, the feces may be partially adhered to the shovel board 22, so the flushing device 3 is required to flush the shovel board 22. In this embodiment, the flushing device 3 includes a second nozzle 31, a second water supply hose 32, a cleaning roller 33, a rotating mechanism 34 and a lifting device 35.

[0031] Similar to the flushing mechanism 23, one end of the second water supply hose 32 is connected to the external water supply device, and the other end is connected to the water inlet end of the second nozzle 31. The water outlet end of the second nozzle 31 is tilted downward in the direction of the cleaning device 2. Below the second nozzle 31, a cleaning roller 33 is provided. The rotating end of the rotating mechanism 34 is coaxially connected to the cleaning roller 33, and can drive the cleaning roller 33 to rotate around its axis to clean the shovel surface of the shovel plate 22. In this embodiment, the rotating mechanism 34 can be a motor. In order to obtain a better cleaning effect, the water flow sprayed by the second nozzle 31 is preferably tangent to the cleaning roller 33, and at the tangent point, the rotation direction of the cleaning roller 33 is the same as the water flow direction. At the same time, similar to the flushing device 3, multiple second nozzles 31 are evenly arranged along the axial direction of the cleaning roller 33 to comprehensively flush the shovel plate 22.

[0032] When cleaning the feces on the scale surface 12, the displacement mechanism 21 pushes the shovel plate 22 forward to push the feces out. When the movement reaches the end, the shovel plate 22 stops moving, and the feces continue to roll down from the slope surface 13 under the action of inertia. In order to clean the shovel plate 22, the cleaning roller 33 needs to face the shovel surface of the cleaning shovel plate 22, but the feces pushed out in this way may fly onto the cleaning roller 33. In order to solve this problem, a lifting device 35 is also provided on the cleaning roller 33 to drive the cleaning roller 33 and the second nozzle 31 and the second water supply hose 32 of the rotating mechanism 34 to rise and fall.

[0033] In this embodiment, the lifting device 35 includes a shell 351 , a connecting rod 352 , a clamping portion 353 , a clamping plate 354 , a reset spring 355 , a trigger portion 356 , a reset push rod 357 , a baffle 358 and a deceleration spring 359 .

[0034] A working chamber is formed in the housing 351, and a first through hole is provided at the bottom to connect the working chamber. The upper end of the connecting rod 352 is fixedly connected to the clamping portion 353, and the lower end passes through the first through hole and is fixedly connected to the cleaning roller 33 and the rotating mechanism 34. At least one clamping plate 354 is movably connected to the inner wall of the working chamber away from the cleaning device 2, and the two ends of the reset spring 355 abut against the clamping plate 354 and the inner wall of the working chamber respectively. In this embodiment, two identical clamping plates 354 are arranged opposite to each other, and the two clamping plates 354 enclose a hole for the connecting rod 352 to pass through. The lower surface of the clamping portion 353 is a horizontal surface, and its upper surface is a conical surface, which is placed on the two clamping plates 354, and the clamping plates 354 carry the clamping portion 353. At this time, the position of the cleaning roller 33 is higher than the shovel plate 22.

[0035] The housing 351 has a second through hole on the side facing the cleaning device 2. One end of the trigger part 356 is fixedly connected to the card away from the cleaning device 2, and the other end passes through the second through hole. The trigger part 356 faces the moving end of the displacement mechanism 21. The reset push rod 357 is vertically arranged in the working chamber, and its moving end is vertically upward. The baffle 358 is arranged above the reset push rod 357 and is fixedly connected to the connecting rod 352. The deceleration spring 359 is sleeved on the connecting rod 352, and the lower end abuts against the bottom surface of the working chamber.

[0036] When large livestock urinates or defecates on the scale face 12, the staff discovers it or uses an intelligent identification device for automatic identification, and activates the displacement mechanism 21 to push the shovel plate 22, the flushing mechanism 23 and the brush 24 to move. The shovel plate 22 shovels away the feces 1, and the flushing mechanism 23 and the brush 24 clean and scrub the surface of the scale face 12 respectively. When the displacement mechanism 21 moves to the end, it also hits the trigger part 356, and the trigger part 356 drives the card plate 354 to move and separate from the other card plate 354 until the clamping part 353 falls from between the two card plates 354. The connecting rod 352, the clamping part 353 and the baffle plate 358 are fixedly connected together and fall together. The baffle plate 358 contacts the deceleration spring 359 and slowly falls under the deceleration effect of the deceleration spring 359. Therefore, when the shovel plate 22 stops moving, the feces first continue to move under the action of inertia and separate from the shovel plate 22, and then the cleaning roller 33 falls and rotates to clean the shovel surface of the shovel plate 22 driven by the rotating mechanism 34. Preferably, a collision switch may be provided in the working chamber. When the trigger portion 356 hits the collision switch, the collision switch is turned on to control the rotating mechanism 34 to start working and the external water supply device to supply water to the second nozzle 31 .

[0037] A cleaning time is preset, and when the time is up, the displacement mechanism 21 retracts to its original position, and the collision switch loses the squeezing of the triggering part 356. On the one hand, the rotation mechanism 34 is controlled to stop working, and the external water supply device stops supplying water to the second nozzle 31. On the other hand, the reset push rod 357 is controlled to push the baffle plate 358 upward, so that the clamping part 353 squeezes through the two clamping plates 354 and rests on the two clamping plates 354 again, completing the reset.

[0038] The implementation of the embodiments of the present invention has the following beneficial effects: the special scale for large livestock includes a scale body, a cleaning device and a flushing device. When large livestock urinate or defecate on the scale body, the displacement mechanism pushes the shovel plate to move, shovel out the feces, and cleans the surface of the scale face through the flushing mechanism and the brush, and then the flushing device flushes the shovel plate to avoid soiling the scale body when returning to its position; by cleaning feces and urine in time, the feces and urine are prevented from contacting the scale body for too long and corroding the scale body.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
