Description

Technical Field

[0001] This application belongs to the field of livestock equipment technology, specifically relating to an electric unmanned total mixed ration (TMR) spreader. Background Technology

[0002] Total Mixed Ration (TMR) feeding technology is a key technology for ensuring nutritional balance in cattle and sheep in modern agricultural breeding. Its core is to provide cattle and sheep with a complete diet with a stable ratio of roughage to concentrate and consistent nutrient concentration by fully mixing roughage, concentrate, minerals, vitamins and other additives. High-performance TMR spreaders are an important supporting equipment for the implementation of this technology.

[0003] Currently, most TMR (Total Mixed Ration) spreader trucks are modified from traditional heavy-duty truck chassis or electric truck chassis. For example, Chinese utility model patent CN219228671U discloses an electric TMR spreader truck, which mainly includes a chassis, a box, an auger, and a spreader. The chassis is an electric truck chassis, which drives the motor through a power battery to achieve movement. At the same time, a hydraulic station is set up to provide power to the auger and spreader, which solves the problems of high engine noise and exhaust emissions that affect the growth of cattle and sheep in traditional fuel chassis. In addition, the hydraulic station is set between the box and the cab, which improves the convenience of maintenance.

[0004] However, the electric TMR feed spreader disclosed in CN219228671U lacks an efficient automatic feeding structure. The feeding process relies heavily on manual spreading or simple mechanical pushing, which is cumbersome, time-consuming, labor-intensive, and inefficient. Furthermore, traditional feeding methods generate large amounts of dust, polluting the aquaculture environment and causing respiratory illnesses in workers, thus harming their health. In addition, some equipment lacks effective solid-gas separation and dust collection structures, further exacerbating the dust pollution problem.

[0005] Existing feed spreaders typically use a fixed auger with a spreader, allowing only unidirectional spreading and making it impossible to flexibly switch between single-sided, double-sided, or center spreading modes depending on the farming scenario. Adjusting the spreading position is inconvenient, making it difficult to precisely control the spreading range and easily leading to feed waste. Furthermore, the spreading channel lacks anti-accumulation design, causing feed to easily stick and accumulate during transport, affecting smooth discharging. When changing feed types, residual feed inside the container is difficult to clean quickly, easily leading to mixing and contamination of different feeds, and making cleaning operations cumbersome.

[0006] In summary, existing TMR feed spreaders have significant shortcomings in terms of feeding methods and discharge functions, which restrict the improvement of breeding efficiency and the optimization of the breeding environment. There is an urgent need for a multi-functional and environmentally friendly electric TMR feed spreader to solve the above problems. Summary of the Invention

[0007] The technical problem to be solved by this application is to overcome the shortcomings of the existing technology and provide an electric unmanned total mixed ration (TMR) spreader. This application achieves an upgrade in automation, efficiency, environmental protection and multi-functionality through all-round innovation in unmanned driving, intelligent feeding, flexible discharge and precise pushing. It is more suitable for the operation needs of modern large-scale farms and can significantly improve breeding efficiency, reduce operating costs and protect the health of livestock and personnel.

The spreading assembly includes a cabinet, a suction-type feeding component, and a discharge component.

[0009] The suction-type feeding assembly includes a feeding separation box located inside the cabinet. An air extraction device is connected to the outside of the air outlet of the feeding separation box, and a corrugated pipe is connected to the inlet of the feeding separation box.

[0010] The discharge assembly includes one or two screw conveyors and a discharge device. The feed end of the screw conveyor is connected to the end of the cabinet away from the feed separation box. The discharge end of the screw conveyor is located outside the cabinet. The discharge device includes a sleeve and a discharge channel that are connected to each other.

[0013] The feed inlet is located on the side wall of the box, and is arranged opposite to the bottom inclined baffle.

[0014] The air outlet is located on the top surface of the enclosure.

[0015] Furthermore, inside the housing, above all the inclined baffles, there are two layers of annular plates spaced apart, with a filter plate placed between the two layers of annular plates. The height between the two layers of annular plates is greater than the thickness of the filter plate.

A disc is provided on the output shaft of the second motor, and several triangular plates are protruding on the circumference of the disc and arranged in a ring array around its axis.

[0024] When the triangular plate rotates to the bottom of the vibration drive block, its inclined surface abuts against the bottom surface of the vibration drive block, gradually pushing the vibration drive block and causing the feeder to move upward. When the triangular plate leaves the vibration drive block, the vibration drive block loses its support, the feeder moves downward, and the feeder moves up and down, generating vibration.

[0025] Furthermore, the cabinet is equipped with a pusher assembly, which includes a pusher plate, a connecting block, a screw, and a third motor arranged along the width of the cabinet.

[0026] The cabinet has a side sliding groove recessed along its length. The connecting block and the screw are set inside the side sliding groove. The third motor, which is fixedly connected to the cabinet, drives the screw to rotate. The connecting block is threadedly connected to the screw through the threaded hole provided on it.

[0027] The bottom of the pusher plate abuts against the bottom surface of the cabinet, and connecting blocks are set at both ends of the pusher plate.

[0028] Furthermore, the pusher plate has rotating shafts at both ends, and a cylindrical block is coaxially fixed at the end of the rotating shaft away from the pusher plate. A rotating plate arranged radially on the circumference of the cylindrical block is fixed thereon.

[0029] The connecting block has a through hole, and the rotating shaft passes through the through hole on the connecting block.

[0030] The side slide groove is equipped with a position adjustment box, and the position adjustment box is connected to the rotating plate slide groove and the limiting block slide groove.

[0031] The cylindrical block is coaxially rotated inside the position adjustment box, and the rotating plate is slidably disposed inside the rotating plate groove. An arc-shaped second spring is provided inside the rotating plate groove.

The lower end of the lifting block extends to the outside of the position adjustment box. A through slot is provided on the lifting block located outside the position adjustment box.

[0033] The limiting block has a right-angled triangle cross-section, with its inclined surface facing the rotating plate when the pusher plate is in a vertical state. A third spring is provided between the horizontal bottom surface of the limiting block and the limiting block groove. Under the push of the third spring, the upper part of the limiting block leaks into the rotating plate groove.

[0034] A limit block drive plate is provided at one end of the side slide groove near the suction feeding assembly. The limit block drive plate is a right-angled triangular plate with the inclined surface facing down.

[0035] The side wall of the cabinet near the discharge assembly is equipped with a pusher plate drive plate facing the pusher plate. The pusher plate drive plate is a triangular plate with its inclined surface facing downward. The top of the inclined surface of the pusher plate drive plate is flush with the top of the pusher plate in the vertical state, and the bottom of the inclined surface of the pusher plate drive plate is flush with the top surface of the pusher plate in the horizontal state.

[0036] Compared with the prior art, the beneficial effects of this application are as follows: (1) The electric unmanned transport platform is adopted. No human driving intervention is required. It can automatically complete the entire process of driving and spreading, which not only reduces the labor input cost of the farm, but also avoids the safety risks such as operation errors and fatigue during human driving. It is especially suitable for large-scale operations in large farms.

[0037] (2) The suction-type feeding assembly, consisting of a negative pressure fan, corrugated pipe, and feeding separation box, can directly draw the prepared total mixed ration into the cabinet under negative pressure, eliminating the need for manual spreading and significantly improving feeding efficiency and reducing labor intensity. During the feeding process, the solid-gas separation structure of the feeding separation box, combined with the dust collection bag at the exhaust port of the suction equipment, significantly reduces dust generation; at the same time, it avoids workers inhaling dust, reducing the risk of respiratory diseases, thus protecting the environment and ensuring the health of the workers.

[0038] (3) The filter plate inside the feed separation box achieves self-cleaning after feeding through a spring structure to avoid clogging; the photoelectric sensor and gravity sensor of the first collection tank are linked to control the valve plate to automatically open and close, ensuring that the feed inlet maintains suction and achieves continuous and stable feeding.

[0039] (4) The feeder can switch between single-sided or double-sided feeding via a single / twin screw feeder. It can also achieve feeding in the middle of the road by opening the lower end cover and using the screw to rotate, which is suitable for different breeding scenarios such as side feeders and middle channels. The feeder can flexibly adjust the angle of the feed channel by rotating the sleeve and using an electric telescopic rod, so as to accurately control the feeding range and avoid feed waste.

[0040] (5) The discharge assembly uses a triangular plate driven by a second motor to cooperate with a vibration drive block, which can realize the up and down vibration of the discharge channel without additional power, effectively preventing the total mixed ration from accumulating in the channel and ensuring smooth discharge.

[0041] (6) When changing the type of feed, the lower end pipe can be used to quickly clear the warehouse, avoid mixing and contamination of different feeds, and improve the precision of breeding.

[0042] (7) The feeding assembly drives the feeding plate to move along the length of the cabinet through the third motor and screw, and accurately pushes the feed discharged from the feeding separation box into the second collection trough of the feeding assembly, so as to avoid the feed from accumulating in the cabinet and ensure continuous operation.

[0043] The pusher plate uses a rotating plate, a limiting block, and a spring to switch between vertical and horizontal states during push and return, solving the problem of feed confusion caused by reverse push during return and improving push stability.

[0044] The automatic switching of the pusher plate state is achieved through the mechanical linkage between the limit block drive plate and the pusher plate drive plate, without the need for additional control logic. The structure is simple and highly reliable.

[0045] (8) The feeding separation box, the pushing component and the discharging component are integrated into the electric transport platform, which has a high space utilization rate and is suitable for the layout of the farm passage; all adopt a modular design, which is detachable and easy to maintain, reducing the cost of use in the later stage.

Detailed Implementation

[0049] The accompanying drawings provide a more detailed description of an electric, unmanned total mixed ration (TMR) spreader, but this is not intended to limit the scope of the application.

[0050] Depend on Figures 1 to 28 As shown, an electric unmanned total mixed ration (TMR) spreader includes a transport platform 28, which is an electric transport platform that uses existing technologies, such as unmanned electric vehicles. The unmanned electric vehicles can be FAW Jiefang's Zhitu series, China National Heavy Duty Truck Group's L4 port tractor, or Karl Power's L4 electric truck.

[0051] A material spreading assembly is mounted on top of the transport platform 28. The material spreading assembly includes a cabinet 24, a suction feeding component, a discharge component, and a pushing component.

[0052] The suction-type feeding component draws the prepared total mixed ration into the cabinet 24 through negative pressure suction. The cabinet 24 is used to store the total mixed ration. The pushing component pushes the total mixed ration discharged by the suction-type feeding component into the discharge component. The discharge component spreads the total mixed ration inside the cabinet 24 into the corresponding area.

[0053] Depend on Figures 11 to 16 As shown, the suction-type feeding assembly includes a feeding separation box 1 installed inside the cabinet 24. An air extraction device 2 is connected to the outside of the air outlet 105 of the feeding separation box 1. A corrugated pipe 3 is connected to the inlet 104 of the feeding separation box 1. Both the air extraction device 2 and the corrugated pipe 3 are installed outside the cabinet 24. The bottom outlet of the feeding separation box 1 is blocked by a hinged valve plate 4.

[0054] The extraction device 2 uses a negative pressure fan, and the corrugated pipe 3 can be extended and bent. During use, the corrugated pipe 3 is pulled to the prepared total mixed ration (MMR) area. The extraction device 2 generates negative pressure, drawing the MMR into the feed separator 1 through the corrugated pipe 3. Solid-gas separation is completed inside the feed separator, and the gas is discharged through the extraction device 2. This feeding method is more time-saving and labor-saving than the previous manual method of scattering the MMR into the cabinet 24 with a shovel, and it also reduces dust generated during the feeding process.

[0055] Covering the air outlet of the exhaust device 2 with a dust collection bag can further reduce the amount of dust generated during feeding, which helps to protect the environment and prevent workers from inhaling too much dust and causing respiratory diseases.

[0056] The feeding separation box 1 includes a box body 101 with an open lower end. A first material collection trough 102 with inclined side plates is connected through the open lower end of the box body 101. The bottom of the first material collection trough 102 is the discharge port of the feeding separation box 1.

[0057] The interior of the housing 101 is provided with two rows of inclined baffles 103 arranged in a staggered manner. The end of the inclined baffle 103 near the center of the housing 101 is lower than the end that abuts against the side wall of the housing 101. That is, the higher part of the baffle 103 is fixedly connected to the side wall of the housing 101, and the lower part of the baffle 103 extends to the other side of the centerline of the housing 101. In this way, from the vertical direction, there is an overlapping area between the two opposing baffles 103; from the horizontal direction, the two opposing baffles 103 are staggered.

[0058] The feed inlet 104 is located on the side wall of the box 101. The feed inlet 104 is arranged opposite to the bottom inclined baffle 103. The first collection trough 102 is located below the bottom inclined baffle 103.

[0059] The air outlet 105 is located on the top surface of the housing 101.

[0060] After the feed enters the housing 101 through the inlet 104, it collides with the inclined baffle 103. Then, guided by the first inclined baffle 103, it flows downwards at an angle. Due to inertia, it flows into the area below the second inclined baffle 103 on the opposite side, impacts the side wall of the housing 101, and then moves upwards to collide with the second inclined baffle 103. Guided by the second inclined baffle 103, it flows downwards at an angle to above the first inclined baffle 103. Then, guided by the first inclined baffle 103, it flows upwards at an angle and collides with the side wall of the housing 101 and the third inclined baffle 103 located directly above the first inclined baffle 103. This process repeats, achieving gas-solid separation of the feed. The solid total mixed ration (TMR) finally slides into the first collection trough 102 under the guidance of the inclined baffle 103.

[0061] To further prevent total mixed ration from entering the vacuum equipment 2, in this embodiment, two annular plates 106 are spaced apart above all the inclined baffles 103 inside the housing 101, and a filter plate 6 is placed between the two annular plates 106. The height between the two annular plates 106 is greater than the thickness of the filter plate 6.

[0062] To achieve self-cleaning of the filter plate 6, in this embodiment, a plurality of vertically arranged first spring support columns 107 protrude from the lower annular plate 106, and a plurality of vertically arranged second spring support columns 601 protrude from the bottom of the filter plate 6. A first spring 7 is sleeved between the first spring support columns 107 and the second spring support columns 601. Under the weight of the filter plate 6 itself, the first spring 7 is compressed. When air is pumped out, the first spring 7 is stretched. When feeding ends, the filter plate 6 and the first spring 7 cooperate with each other. Under the elastic force of the first spring 7 and the inertia of the filter plate 6, the filter plate 6 will shake up and down several times, thereby achieving self-cleaning of the filter plate 6.

[0063] One end of the valve plate 4 is hinged to the first collection trough 102 via a hinge shaft and a bracket. The valve plate 4 is fixedly connected to the output shaft of the first motor 5 via the hinge shaft. The first motor 5 is fixedly connected to the housing 101 or the first collection trough 102.

[0064] A set of through-beam photoelectric sensors are arranged opposite each other on the side wall of the first collection trough 102. These sensors detect the collection height of the total mixed ration (TMR) inside the trough. A gravity sensor is installed on the valve plate 4. When the weight detected by the gravity sensor reaches a threshold, the sensor transmits a signal to the control module. The control module then starts the first motor 5, opening the valve plate 4. In this embodiment, the valve plate 4 automatically opens after the first collection trough 102 is filled with TMR. After the valve plate 4 opens, the TMR is discharged. When the TMR inside the first collection trough 102 descends to the position of the through-beam photoelectric sensor, the sensor transmits a signal to the control module. The control module then starts the first motor 5, closing the valve plate 4. This ensures that the discharge port below the first collection trough 102 is consistently blocked by either the TMR or the valve plate 4, maintaining the suction force at the bellows 3 opening.

[0065] The control module is the core control unit, the photoelectric sensor and gravity sensor are input peripherals, and the first motor 5 is the output peripheral. The three interact with the control module through an electrical interface.

[0066] The through-beam photoelectric sensor can be an NPN / PNP type switch output through-beam photoelectric sensor. The transmitter and receiver of the sensor are respectively installed at opposite positions on the side wall of the first collection tank 102. The signal output pin of the sensor is connected to the digital input port of the control module, and the power supply pin of the sensor is connected to a 24VDC power supply, which is powered by the control module or an external power supply. The ground wire is shared with the control module.

[0067] When the total mixed ration (TMR) obstructs the receiver, the sensor outputs a low level; when the ration descends to the sensor height and the receiver is unobstructed, it outputs a high level.

[0068] The gravity sensor is either an analog output type or a digital output type. The sensor is mounted on valve plate 4, and its signal output pin is connected to the analog input port or digital input port of the control module; the power supply pin is connected to a 24VDC power supply, and the ground wire is common to the ground.

[0069] When the weight of the daily ration borne by the valve plate 4 reaches the set threshold, the analog sensor outputs the corresponding voltage / current signal, and the digital sensor directly outputs a high-level trigger signal.

[0070] The first motor 5 enables forward and reverse rotation and is used to open / close the valve plate 4, and is equipped with a motor driver. The digital output port of the control module is connected to the control pins of the forward control terminal, reverse control terminal, and enable terminal of the motor driver; the output terminal of the motor driver is connected to the power supply pin of the first motor 5; the control module controls the driver to drive the motor to rotate forward, reverse, or stop by outputting high and low level signals.

[0071] have Figures 17 to 20As shown, the discharge assembly includes one or two screw conveyors and a discharge device 12. One screw conveyor enables unilateral material feeding, while two screw conveyors enable bilateral material feeding. The screw conveyors are arranged vertically, with their inlet end connected to the end of the cabinet 24 away from the inlet separation box 1, and their outlet end located above and outside the cabinet 24. The discharge device 12 includes a sleeve 1201 and a discharge channel 1202 that are connected to each other. A lower discharge port 1203 is provided below the end of the discharge channel 1202 away from the sleeve 1201. The sleeve 1201 is fitted outside the discharge area of ​​the screw conveyor. The discharge channel 1202 is arranged at an angle, with the discharge port 1203 lower than the end that is connected to the sleeve 1201.

[0072] The cabinet 24 is located in the area below the screw feeder and has a second collection trough 2402. The second collection trough 2402 is connected to the inside of the cabinet 24 through a through channel 2401. The second collection trough 2402 is provided with an inclined guide plate 2403. The guide plate 2403 guides the total mixed ration entering through the through channel 2401 to the connection between the second collection trough 2402 and the screw feeder.

[0073] The screw feeder includes a vertically arranged feed pipe 9, a screw rod 8 inside the feed pipe 9, and a second motor 10 connected to the screw rod 8 outside the feed pipe 9. The bottom of the feed pipe 9 is connected to the second collection trough 2402, and the bottom of the screw rod 8 is inserted into the second collection trough 2402.

[0074] Several discharge holes 901 are provided on the top circumferential surface of the conveying pipe 9. The discharge holes 901 are located inside the sleeve 1201, and the connection between the sleeve 1201 and the discharge channel 1202 is arranged opposite to the discharge holes 901. The rotating screw 8 feeds the total mixed ration inside the second collection trough 2402 into the conveying pipe 9, and then discharges it into the discharge channel 1202 through the discharge holes 901, and finally discharges it through the lower discharge port 1203.

[0075] Since the sleeve 1201 can rotate, the position of the feeder 12 can be adjusted, thus changing the feeding position.

[0076] To optimize the conveying effect of the screw rod 8 and simultaneously empty the total mixed ration (TMR) inside the cabinet 24, in this embodiment, a lower end pipe 2404 is connected through the bottom of the second collection trough 2402. The lower end pipe 2404 is coaxially arranged with the conveying pipe 9. The screw rod 8 is inserted into the lower end pipe 2404. A connecting frame 2405, which sleeves and supports the screw rod 8, is fixed inside the lower end pipe 2404. A lower cover 25 is detachably connected to the open bottom of the lower end pipe 2404. When the lower cover 25 is opened, the screw rod 8 flips, allowing the TMR to be spread through the lower end pipe 2404. This is suitable for spreading the TMR in the middle of the road or for emptying the cabinet 24 when changing to other types of TMR.

[0077] To adjust the rotation angle of the discharge device 12, a vertically arranged rotating rod 1205 is fixed at the bottom of the discharge channel 1202, and a fixed base 14 is fixed on the top of the cabinet 24. A telescopic rod 13 is provided between the fixed base 14 and the rotating rod 1205, and both ends of the telescopic rod 13 are rotatably connected to the rotating rod 1205 and the fixed base 14, respectively. The telescopic rod 13 is an electric telescopic rod, powered by the transport platform 28.

[0078] In order to optimize the feeding effect of the discharge channel 1202 and avoid the accumulation of total mixed ration inside it, in this embodiment, a vibration drive block 1204 is connected above the discharge channel 1202 near the end of the sleeve 1201 by a vertical rod. A disc 11 is provided on the output shaft of the second motor 10. Several triangular plates 1101 are protruding on the circumferential surface of the disc 11 and arranged in a ring array around its axis.

[0079] When the triangular plate 1101 rotates to a position below the vibration drive block 1204, its inclined surface abuts against the bottom surface of the vibration drive block 1204, gradually pushing the vibration drive block 1204 to move the feeder 12 upward. When the triangular plate 1101 leaves the vibration drive block 1204, the vibration drive block 1204 loses its support, the feeder 12 moves downward, and the feeder 12 vibrates as it moves up and down.

[0080] This eliminates the need for additional power; the up-and-down vibration of the feeder 12 is achieved through the combined use of the triangular plate 1101 and the vibration drive block 1204, optimizing the material discharge effect of the discharge channel 1202. Since the discharge channel 1202 moves up and down, the height of the connecting sleeve 1301, which connects the telescopic rod 13 and the rotating rod 1205, is less than the height of the rotating rod 1205. Similarly, the height of the rotating shaft on the fixed base 14 is higher than the height of the corresponding sleeve hole on the telescopic rod 13.

[0081] Existing TMR feed spreading equipment mostly relies on the auger's own conveying function to push feed, resulting in limited pushing efficiency and a lack of dedicated pushing components to accurately guide the feed within the container to the discharge mechanism, easily leading to localized feed accumulation within the container. Furthermore, the pushing structure lacks an anti-reverse pushing design, which can easily bring back feed already pushed to the discharge end during the pushing component's reset process, causing chaotic feed distribution and affecting the smooth connection between feeding and discharging. To solve this problem, a pushing component is added in this embodiment.

[0082] Depend on Figures 21 to 28 As shown, the material pushing assembly includes a material pushing plate 15, a connecting block 16, a screw 22, and a third motor 23 arranged along the width direction of the cabinet 24.

[0083] The cabinet 24 has a side sliding groove 2406 recessed along its length. The connecting block 16 and the screw 22 are located inside the side sliding groove 2406. The third motor 23, which is fixedly connected to the cabinet 24, drives the screw 22 to rotate. The connecting block 16 is threadedly connected to the screw 22 through the threaded hole 1601 provided on it.

[0084] The bottom of the pusher plate 15 abuts against the bottom surface of the cabinet 24. The connecting block 16 is set at both ends of the pusher plate 15. The third motor 23 drives the screw 22 to rotate, which in turn drives the connecting block 16 to move along its axis. The connecting block 16 drives the unloading plate 15 to move, pushing the mixed grain from below the feeding separation box 1 into the second collection trough 2402.

[0085] To prevent the third motor 23 from reversing and the pusher plate 15 from pushing material in the opposite direction during its return to the bottom of the feeding separation box 1, in this embodiment, the pusher plate 15 is converted to a horizontal state when it returns, which solves the problem of reverse material pushing. To achieve this technical effect, in this embodiment, the pusher plate 15 is provided with rotating shafts 1501 at both ends. A cylindrical block 1502 is coaxially fixed at one end of the rotating shaft 1501 away from the pusher plate 15. A rotating plate 1503 arranged radially on the circumferential surface of the cylindrical block 1502 is fixed thereon. A through hole is provided on the connecting block 16, and the rotating shaft 1501 passes through the through hole on the connecting block 16.

[0086] A position adjustment box 17 is slidably mounted inside the side slide groove 2406. The position adjustment box 17 can only slide along the side slide groove 2406 and cannot rotate. This function can be achieved by the shape of the position adjustment box 17, for example, its shape is polygonal, and its top and bottom surfaces abut against the top and bottom surfaces of the side slide groove 2406. The position adjustment box 17 has a rotating plate slide groove 1701 and a limiting block slide groove 1702 that are interconnected inside. The limiting block slide groove 1702 is located directly below the rotating plate slide groove 1701, and the angle of the rotating plate slide groove 1701 is 150° to 220°.

[0087] The cylindrical block 1502 is coaxially rotatably disposed inside the position adjustment box 17, and the rotating plate 1503 is slidably disposed inside the rotating plate groove 1701. The rotating plate groove 1701 is provided with an arc-shaped second spring 18. Under the push of the second spring 18, the rotating plate 1503 abuts against one end of the rotating plate groove 1701, at which time the pusher plate 15 is in a vertical state.

[0088] The limiting block 19 is provided inside the limiting block slide groove 1702 and slides up and down. A lifting block 1901 is fixed at the bottom of the limiting block 19. The lower end of the lifting block 1901 extends to the outside of the position adjustment box 17. A through slot 1902 is provided on the lifting block 1901 located outside the position adjustment box 17.

[0089] The limiting block 19 has a right-angled triangle cross-section, with its inclined surface facing the rotating plate 1503 when the pusher plate 15 is in a vertical state. A third spring 20 is provided between the horizontal bottom surface of the limiting block 19 and the limiting block groove 1702. Under the push of the third spring 20, the upper part of the limiting block 19 leaks into the rotating plate groove 1701.

[0090] The side slide groove 2406 is provided with a limit block drive plate 21 at one end near the suction feeding assembly. The limit block drive plate 21 is a right-angled triangular plate with the inclined surface facing down. The front end of the inclined surface of the limit block drive plate 21 is arranged opposite to the bottom surface of the slot 1902.

[0091] The side wall of the cabinet 24 near the discharge assembly is provided with a pusher plate drive plate 27 facing the pusher plate 15. The pusher plate drive plate 27 is a triangular plate with its inclined surface facing downward. The top of the inclined surface of the pusher plate drive plate 27 is flush with the top of the pusher plate 15 in the vertical state, and the bottom of the inclined surface of the pusher plate drive plate 27 is flush with the top surface of the pusher plate 15 in the horizontal state.

[0092] When the pusher plate 15 moves to the discharge assembly end, the pusher plate drive plate 27 collides with the pusher plate 15. The inclined surface of the pusher plate drive plate 27 pushes the pusher plate 15 to rotate, and the rotating plate 1503 rotates inside the rotating plate groove 1701 against the thrust of the second spring 18. After it abuts against the inclined surface of the limiting block 19, it pushes the limiting block 19 downward, and then rotates to behind the limiting block 19. When it passes the limiting block 19, the limiting block 19 moves upward under the push of the third spring 20, and the vertical surface of the limiting block 19 abuts against the rotating plate 1503 to block it. At this time, the pusher plate 15 has rotated exactly 90°, changing from a vertical state to a horizontal state.

[0093] The third motor 23 rotates and drives the pusher plate 15 to move towards the feeding separation box 1. At this time, the pusher plate 15 is in a horizontal state, so it will not produce a pushing effect.

[0094] After the pusher plate 15 moves past the feeding separation box 1, the inclined surface of the limit block drive plate 21 abuts against the bottom surface of the slot 1902 of the limit block 19. The pusher plate 15 continues to move, and the limit block drive plate 21 is inserted into the slot 1902. Its inclined surface presses down on the limit block 19. When the limit block 19 moves out of the rotating plate slide 1701, the rotating plate 1503 rotates and resets under the push of the second spring 18, so that the pusher plate 15 rotates to a vertical state, which can produce a pushing effect.

[0095] An openable access cover 26 is provided on the top surface of the cabinet 24 to facilitate cleaning and maintenance of its interior.

[0096] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
