Description

Technical Field

[0001] The present invention relates to the technical field of breeding machinery, and particularly relates to a timed and quantitative feeding component, an automatic feeding device, and a feeding method thereof. Background Art

[0002] In modern aquaculture, improving aquaculture efficiency, reducing labor costs, and ensuring animal health are important challenges faced by aquaculturists. Traditional aquaculture feeding methods highly rely on manual operation. This mode is not only inefficient, but also difficult to ensure timed and quantitative feeding, easily leading to problems such as feed waste and unbalanced animal growth. With the progress of technology and the development of automation technology, automatic feeding devices have gradually become the mainstream solution for aquaculture owners. However, existing devices still have significant shortcomings in terms of feeding accuracy, dynamic adaptability, cleaning, and maintenance.

[0003] On the one hand, most existing automatic feeding devices adopt open-loop control systems and lack closed-loop feedback adjustment mechanisms. Due to the significant differences in dynamic requirements at different growth stages of animals, traditional devices are difficult to achieve precise control of the feeding amount, and the feeding amount often fluctuates with an error exceeding ±10%, directly affecting the healthy growth indicators of animals.

[0004] On the other hand, there are obvious deficiencies in the uniformity of feed distribution in existing devices. Especially in farms with a scale of over 10,000 heads, due to unreasonable layout of feeding points and mechanical structure limitations, about 30% of the animals in the marginal areas have insufficient feed intake, while the feed residue rate in the central area is as high as 15%, resulting in systematic resource waste.

[0005] In addition, the technical bottleneck in the equipment cleaning and maintenance link is particularly prominent. Most traditional devices adopt fixed scraper structures and lack self-adaptive cleaning mechanisms, resulting in a feed residue cleaning rate of less than 60%. If not dealt with in time, these residues will not only pollute the aquaculture environment, but also be more likely to breed pathogenic bacteria groups, forming a major biosafety hazard.

[0006] In view of the above problems, the present invention document proposes a timed and quantitative feeding component, an automatic feeding device, and a feeding method thereof. Summary of the Invention

[0007] The present invention provides a timed and quantitative feeding component, an automatic feeding device, and a feeding method thereof, which solve the disadvantages that existing automatic feeding devices are often difficult to achieve timed and quantitative feeding, cannot evenly distribute feed, and cannot centrally collect feed residues after animals eat.

[0008] The present invention provides the following technical solutions:

[0009] A timed and quantitative feeding component, including a ground rail;

[0010] The chassis is slidably arranged on the ground rail. Driving motors are symmetrically arranged on both sides of the chassis. The output shaft of the driving motor penetrates through the chassis and is in transmission connection with the wheels. The wheels form a rolling fit with the ground rail. It further includes:

[0011] A lifting mechanism, including a connecting frame fixed to the top of the chassis, a moving rod slidably connected to the connecting frame, and a U-shaped frame rigidly connected to the moving rod. The U-shaped frame is rotatably connected to the feeding box through a support shaft. A vibration motor is arranged at the bottom of the feeding box;

[0012] A support mechanism, symmetrically arranged on both sides of the feeding box, including a limiting frame fixed to the connecting frame, a limiting plate slidably connected to the limiting frame, and a transmission cover arranged on the side wall of the feeding box. A transmission plate pivotally connected to the limiting frame is arranged in the transmission cover. A compression spring is arranged between the transmission plate and the transmission cover;

[0013] A discharging mechanism, including a feeding hopper arranged at the discharging opening of the feeding box, a stepping motor drivingly connected to the feeding hopper, and a sealing plate driven by the stepping motor. The sealing plate forms a cooperation with the feeding hopper with an adjustable opening degree;

[0014] Wherein, the moving rod is driven to achieve longitudinal displacement through a screw-nut mechanism (12, 14). When the moving rod moves downward, the feeding box is turned downward through the cooperation between the transmission plate and the limiting frame, and at the same time, the compression spring stores energy. The stepping motor controls the opening degree of the sealing plate to achieve quantitative feeding.

[0015] As a further improvement of the above technical solution:

[0016] The screw-nut mechanism includes: a driving motor fixed to the top of the chassis; a screw driven to rotate by the driving motor; a moving frame forming a threaded transmission with the screw through a nut. Wherein, the bottom end of the moving rod is rigidly connected to the moving frame, and the top end of the screw forms a rotating pair with the mounting frame through a bearing.

[0017] The transmission plate of the support mechanism forms a rotating pair with the limiting frame through a pin shaft. A guiding chute is arranged on the inner wall of the transmission cover to form a sliding fit with the transmission plate. Both ends of the compression spring respectively abut against the inner wall of the transmission cover and the transmission plate. The sealing plate of the discharging mechanism is fixed to a rotating shaft through a mounting strip. The rotating shaft is in transmission connection with the stepping motor through a key connection. A sealing surface matching the inner wall shape of the feeding hopper is arranged at the edge of the sealing plate.

[0018] An automatic feeding device includes:

[0019] A timing and quantitative feeding assembly as described above;

[0020] The feeding trough is arranged on the side of the ground rail, and discharge holes are provided on the side wall of the feeding trough; the cleaning mechanism includes a sliding plate slidably connected to the feeding trough, an electric push rod arranged on the sliding plate, and a cleaning plate driven by the electric push rod; the blocking mechanism includes a cover plate hinged to the feeding trough and a torsion spring arranged on the hinge shaft; wherein, the cleaning plate forms a linkage with the feeding component through a connecting rod and a connecting pipe, and when the feeding component moves in the reverse direction, the cleaning plate is driven to scrape the feed residue and push open the cover plate for discharge.

[0021] As a further improvement of the above technical solution:

[0022] The cleaning mechanism further includes: a mounting shaft vertically fixed to the sliding plate; a support frame slidably sleeved on the mounting shaft through a collar; wherein, one end of the connecting pipe is hinged to the collar, and the other end is slidably sleeved on a connecting rod fixedly connected to the feeding component.

[0023] The pre-tightening force of the torsion spring of the blocking mechanism is set to 10 - 15 N·mm, the opening angle range of the cover plate is 0° - 75°, and the cover plate opens when the cleaning plate applies a thrust ≥ 5 N.

[0024] It further includes a control display screen, and the control display screen is provided with: a timing module for presetting multiple feeding time periods; a feedback adjustment module for dynamically adjusting the opening of the stepping motor according to the residue amount in the feeding trough; wherein, the moving speed v of the driving motor and the opening θ of the closing plate satisfy the relationship: v = k·θ, where k is the feed flow coefficient.

[0025] The feedback adjustment module includes: a vision sensor arranged above the feeding trough for detecting the uniformity of feed distribution; a pressure sensor arranged on the contact surface of the cleaning plate for detecting the scraping resistance; wherein, when the detected deviation of uniformity > 15% or the scraping resistance > 8 N, the cleaning program is automatically triggered and the feeding parameters for the next cycle are adjusted.

[0026] A feeding method is applied to the automatic feeding device as described above, including the following steps:

[0027] S1. Feeding trough installation structure: The longitudinal sliding connection between the collar and the mounting shaft, and the transverse telescopic structure composed of the connecting pipe and the connecting rod provide freedom for the installation of the feeding trough.

[0028] S2. Automatic tilting mechanism of the feeding box: The driving motor drives the screw rod to drive the moving frame to move longitudinally. Through the cooperation of the U-shaped frame and the transmission plate - transmission cover, the feeding box is tilted downward until the feeding hopper is aligned with the feeding trough, and the compression spring provides the reset elastic force.

[0029] S3. Feed delivery control system: The stepping motor drives the closing plate to adjust the opening of the feeding box, and simultaneously drives the wheels to move uniformly along the ground rail through the driving motor to achieve precise feed delivery.

[0030] S4. Feed residue cleaning device: The electric push rod drives the cleaning plate to fit the inner wall of the feeding trough. When the device moves in the reverse direction, it drives the cleaning plate to scrape the feed residue horizontally, and the waste is discharged through the automatic opening and closing of the discharge hole cover plate.

[0031] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0032] Beneficial effects: For the timing and quantitative feeding component, through the provided lifting mechanism, it can be longitudinally slidably connected to the four moving rods by means of the connecting frame. After the four moving rods receive the power of the driving component, they can drive the feeding box to move longitudinally. And under the supporting action of the two supporting mechanisms, the feeding box can be longitudinally flipped. Therefore, when the four moving rods move downward, they can drive the feeding box to rotate downward, so as to facilitate the outflow of feed from the feeding box.

[0033] For the timing and quantitative feeding component, through the provided supporting mechanism, the transmission plate can only rotate under the supporting action of the limiting frame and cannot move downward. Therefore, when the feeding box moves downward along with the U-shaped frame, it will form a rotational support for the feeding box under the transmission cooperation of the transmission plate and the transmission cover. So the feeding box can be flipped and tilted downward, and at the same time, the transmission plate and the transmission cover will slide relative to each other, compressing the compression spring and keeping the compression spring in a stressed state. Therefore, when pushing the feeding box upward for reset, the stressed compression spring can use its own elastic force to push the transmission cover and the transmission plate to move in the reverse direction, so as to facilitate the reset adjustment of the feeding box to the horizontal direction.

[0034] For the timing and quantitative feeding component, through the provided discharging mechanism, the sealing plate can block the opening of the feeding box, thereby preventing the feed from flowing out randomly. When it is necessary to discharge the feed, the stepping motor can be started to drive the rotating shaft to rotate, so as to drive the sealing plate to rotate and disengage from the opening of the feeding box. At this time, the feed can flow out, and at the same time, the stepping motor can control the rotation angle of the sealing plate, so as to adjust the outflow rate of the feed.

[0035] The described automatic feeding device, through the provided cleaning mechanism, when the feeding trough is installed on the breeding rack for breeding poultry, since the collar and the mounting shaft are longitudinally slidably connected, and the transverse telescopic structure composed of the connecting pipe and the connecting rod, it can provide good freedom during the installation of the feeding trough. When it is necessary to clean the feed residue in the feeding trough, first start the electric push rod to move the cleaning plate into the feeding trough, so that the cleaning plate fits the inner wall of the feeding trough. Then, when the connecting frame moves horizontally, it can drive the support frame to move horizontally under the driving action of the connecting rod, the connecting pipe and the mounting shaft. At this time, the cleaning plate can move horizontally in the feeding trough, so as to scrape and clean the feed residue falling in the feeding trough, thus facilitating the centralized collection of the feed residue;

[0036] The described automatic feeding device, through the provided blocking mechanism, in the normal state, the cover plate can be elastically supported by the elastic force of two torsion springs, so that the cover plate blocks the discharge hole. When the pushed feed residue moves to generate a thrust on the cover plate, at this time the cover plate can rotate, making the discharge hole in an open state, so as to discharge the feed residue from the discharge hole, facilitating the collection of the feed residue.

[0037] In the actual use process of the present invention, it can automatically and continuously feed the feed into the feeding trough, facilitating the feeding of many poultry animals. And after the poultry animals finish eating, it can conveniently clean the feed residue in the feeding trough, thus facilitating the collection of the feed residue, effectively avoiding the problem of feed pollution.

[0048] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present invention.

[0050] Embodiment 1: Refer toFigure 1-7 , a feeding component, comprising a ground rail 1 and a chassis 2 located above the ground rail 1. Two driving motors 3 are symmetrically and fixedly installed on both inner walls of the chassis 2 through bolts. The output shaft of the driving motor 3 penetrates through one inner wall of the chassis 2 and extends to the outside of the chassis 2. A wheel 4 is fixedly sleeved on the output shaft of the driving motor 3 through a shaft sleeve. The bottom of the wheel 4 is located within the ground rail 1 and can move linearly along the track on the ground rail 1.

[0051] As Figure 3 and Figure 4 shown, a lifting mechanism is installed on the chassis 2. A feeding box 10 is connected to the lifting mechanism. Two vibration motors 44 are fixedly installed on the bottom of the feeding box 10 through bolts. The feeding box 10 is used to load feed. The lifting mechanism includes a connecting frame 5 welded to the top of the chassis 2. Four moving rods 6 are symmetrically and slidably connected to the connecting frame 5. A U-shaped frame 7 located above the connecting frame 5 is welded on the moving rods 6. A support shaft 8 is welded inside the U-shaped frame 7. Two connecting blocks 9 are symmetrically rotatably sleeved on the support shaft 8. The tops of the two connecting blocks 9 are welded to one side of the bottom of the feeding box 10. An installation frame 15 is welded inside the connecting frame 5. Two support mechanisms are symmetrically installed on the top of the installation frame 15. A driving component is installed inside the connecting frame 5. The driving component is respectively connected to the bottom ends of the four moving rods 6 and can drive the four moving rods 6 to move longitudinally to realize driving the feeding box 10 to move longitudinally.

[0052] As Figure 3 and Figure 4 shown, the driving component includes a driving motor 11 fixedly installed on the top of the chassis 2 through bolts. The bottom ends of the four moving rods 6 are welded to the same moving frame 13. The moving frame 13 is located below the installation frame 15. A nut 14 is welded to the top of the moving frame 13. A screw rod 12 is welded to the output shaft of the driving motor 11. The top end of the screw rod 12 penetrates through the moving frame 13 and the nut 14 and extends above the nut 14. The top end of the screw rod 12 is rotationally connected to the bottom of the installation frame 15 through a bearing. The screw rod 12 is threadedly connected to the nut 14. By starting the driving motor 11 to drive the screw rod 12 to rotate, at this time, under the action of the threaded transmission with the nut 14, the moving frame 13 can be driven to move longitudinally. When the moving frame 13 moves downward, the feeding box 10 can be driven to move downward through the four moving rods 6, the U-shaped frame 7, the support shaft 8 and the two connecting blocks 9, so as to drive the feeding box 10 to turn downward, facilitating the discharge of the feed.

[0053] As Figure 4 and Figure 6As shown in the figure, the support mechanism includes a limit frame 16 welded to one side of the top of the mounting frame 15. A limit plate 17 is slidably connected through the limit frame 16, and the limit plate 17 is welded to one side of the U-shaped frame 7. It also includes a transmission cover 18 welded to one side of the feeding box 10. A transmission plate 19 is slidably connected in the transmission cover 18. A pin shaft is rotatably connected to the transmission plate 19, and one end of the pin shaft extends to the outside of the transmission cover 18 and is welded to the top of one side of the limit frame 16. A spring 20 is installed on the inner wall of one side of the transmission cover 18 through a spring seat, and the other end of the compression spring 20 abuts against one side of the transmission plate 19 through a spring seat. Under the support of the limit frame 16, the transmission plate 19 can only rotate and cannot move downward. Therefore, when the feeding box 10 moves downward along with the U-shaped frame 7, it will form a rotational support for the feeding box 10 through the transmission cooperation between the transmission plate 19 and the transmission cover 18. Therefore, the feeding box 10 can be tilted downward, and at the same time, the transmission plate 19 and the transmission cover 18 will slide relative to each other, compressing the compression spring 20 and keeping the compression spring 20 in a stressed state. Therefore, when pushing the feeding box 10 upward for reset, the stressed compression spring 20 can use its own elastic force to push the transmission cover 18 and the transmission plate 19 to move in the reverse direction, so as to conveniently adjust the feeding box 10 to the horizontal position for reset.

[0054] As Figure 4 and Figure 7 shown, the feeding assembly further includes a discharging mechanism connected to the opening side of the feeding box 10. The discharging mechanism can close or open the opening of the feeding box 10, so as to conveniently control and adjust the outflow rate of the feed. The discharging mechanism includes a feeding hopper 21 welded to the opening side of the feeding box 10. A stepping motor 22 is fixedly installed on the feeding hopper 21 by means of bolts. A rotating shaft 23 is welded to the output shaft of the stepping motor 22. One end of the rotating shaft 23 is rotatably connected to the feeding hopper 21. An installation strip 24 is fixedly sleeved on the rotating shaft 23 by means of key connection. A sealing plate 25 is welded to one side of the installation strip 24. The bottom of the sealing plate 25 is inserted into the feeding hopper 21 and cooperates with the feeding hopper 21. The sealing plate 25 can close the opening of the feeding box 10. By using the sealing plate 25, the opening of the feeding box 10 can be blocked, so as to prevent the feed from flowing out randomly. When the feed needs to be discharged, the stepping motor 22 can be started to drive the rotating shaft 23 to rotate, so as to drive the sealing plate 25 to rotate and separate from the opening of the feeding box 10. At this time, the feed can flow out. At the same time, the stepping motor 22 can control the rotation angle of the sealing plate 25, so as to adjust the outflow rate of the feed.

[0055] This application can be used in the technical field of breeding machinery and can also be used in other fields applicable to this application.

[0056] Example 2: Refer to Figure 1-8, improved on the basis of Embodiment 1: A timed and quantitative feeding component, which is applied to the field of aquaculture machinery technology. A device frame 26 is welded on one side of the ground rail 1. A control display screen 27 is fixedly installed on the device frame 26 by bolts. A processor is arranged in the control display screen 27. The processor is electrically connected to four driving motors 3, a driving motor 11, two vibration motors 44 and a stepping motor 22 respectively. A timer is also arranged in the control display screen 27. The timer is electrically connected to the controller. By operating the control display screen 27, the time period of the timer is adjusted. In this way, when it is necessary to feed the feed, a working instruction can be sent to the processor by timing, so that the four driving motors 3, the driving motor 11, the two vibration motors 44 and the stepping motor 22 can be started to operate. In this way, when feeding the feed, automatic feeding of the feed can be realized on time.

[0057] Embodiment 3: Refer to Figure 1 , Figure 2 and Figure 8 , an automatic feeding device, including a feeding trough 29 arranged on one side of the ground rail 1. A discharge hole is opened on the inner wall of one side of the feeding trough 29. A positioning frame 28 is welded on one side of the feeding trough 29. The positioning frame 28 is used to install the feeding trough 29 on the breeding frame for breeding poultry. A slide rail 34 is welded on the other side of the feeding trough 29. A cleaning mechanism is connected to the slide rail 34. The top of the cleaning mechanism extends above the feeding trough 29. The bottom of the cleaning mechanism can be inserted into the feeding trough 29 to push the feed residue existing in the feeding trough 29 out of the discharge hole, so as to facilitate the collection of the feed residue.

[0058] Such as Figure 1 and Figure 8As shown in the figure, the cleaning mechanism includes a slide plate 35 slidably connected to the slide rail 34. On one side of the top of the slide plate 35, a mounting shaft 36 is welded. At the top of the mounting shaft 36, a support frame 37 is welded. At the top of the support frame 37, a fixed frame 38 is welded. On the top of the fixed frame 38, an electric push rod 39 is fixedly installed by means of bolts. The electric push rod 39 is electrically connected to the processor. The output shaft of the electric push rod 39 extends into the fixed frame 38 and a cleaning plate 40 is fixedly installed by bolts. The cleaning plate 40 is in contact with the inner wall of the feeding trough 29. A collar 43 is also slidably sleeved on the mounting shaft 36. On one side of the collar 43, a connecting pipe 42 is welded. A connecting rod 41 is slidably connected in the connecting pipe 42. One end of the connecting rod 41 extends to the outside of the connecting pipe 42 and is welded to the top of one side of the connecting frame 5. When the feeding trough 29 is installed on the breeding frame for breeding poultry, at this time, due to the longitudinal sliding connection between the collar 43 and the mounting shaft 36, and the transverse telescopic structure composed of the connecting pipe 42 and the connecting rod 41, it can provide good freedom when installing the feeding trough 29. When it is necessary to clean the feed residue in the feeding trough 29, first start the electric push rod 39 to move the cleaning plate 40 into the feeding trough 29 so that the cleaning plate 40 is in contact with the inner wall of the feeding trough 29. Then, when the connecting frame 5 moves horizontally, it can drive the support frame 37 to move horizontally under the driving action of the connecting rod 41, the connecting pipe 42 and the mounting shaft 36. At this time, the cleaning plate 40 can move horizontally in the feeding trough 29, so as to scrape and clean the feed residue falling in the feeding trough 29, so as to facilitate the centralized collection of the feed residue.

[0059] As Figure 1 shown, the feeding device further includes a blocking mechanism installed on one side of the feeding trough 29. One side of the blocking mechanism extends into the discharge hole for blocking the discharge hole to prevent the feed from flowing out of the discharge hole during the feeding process of the poultry. The blocking mechanism includes a hinge shaft 30 welded to one side of the feeding trough 29. A connecting strip 31 is rotatably sleeved on the hinge shaft 30. On one side of the connecting strip 31, a cover plate 32 is welded. The cover plate 32 is used to block the discharge hole. Two torsion springs 33 are symmetrically sleeved on the hinge shaft 30. The two ends of the torsion spring 33 are respectively welded to one end of the hinge shaft 30 and one side of the connecting strip 31. In the normal state, the cover plate 32 can be elastically supported by the elastic force of the two torsion springs 33, so that the cover plate 32 blocks the discharge hole. When the pushed feed residue moves to generate a thrust on the cover plate 32, at this time, the cover plate 32 can rotate to make the discharge hole in an open state, so that the feed residue can be discharged from the discharge hole for collecting the feed residue.

[0060] Among them, the outlet cross-section of the feeding hopper 21 can be configured in the following shapes, including but not limited to:

[0061] 1. Tapered bell mouth (the outlet diameter reduction rate is 15 - 25%); Star-shaped diversion port (4 - 6 radial guide vanes are provided); 3. Spiral guide port (the guide angle is 30 - 45°).

[0062] The working edge of the cleaning plate 40 can adopt: 1. Triangular serrated edge (tooth pitch 10 - 15 mm, suitable for cleaning high-viscosity feed); 2. Trapezoidal wavy edge (wave crest height 5 - 8 mm, improving the scraping uniformity); 3. Composite curved surface edge (curvature radius R20 - R50 mm, reducing feed adhesion).

[0063] The spring stiffness of the compression spring 20 is preferably 80 - 150 N / mm, the compression stroke is designed to be 20 - 50 mm, the wire diameter of the spring is Φ3 - Φ5 mm, and the number of effective turns is 6 - 8 turns, ensuring an elastic restoring force of 12 - 25 N when the feeding box 10 flips and resets.

[0064] The present invention proposes a feeding method, which is applied to the automatic feeding device as described above, and includes the following steps:

[0065] S1. When the feeding trough 29 is installed on the breeding rack for breeding poultry, at this time, since the collar 43 and the mounting shaft 36 are longitudinally slidably connected, and the transverse telescopic structure composed of the connecting pipe 42 and the connecting rod 41, it can provide good freedom when installing the feeding trough 29.

[0066] S2. Pre-load the feed into the feeding box 10, and then start the driving motor 11 to run by operating the control display screen 27. At this time, the screw 12 can be driven to rotate. At this time, under the screw drive action with the nut 14, the moving frame 13 can be driven to move longitudinally. When the moving frame 13 moves downward, the feeding box 10 can be driven to move downward through the four moving rods 6, U-shaped frame 7, support shaft 8 and two connecting blocks 9. Since the transmission plate 19 is supported by the limit frame 16 and can only rotate and cannot move downward, when the feeding box 10 moves downward with the U-shaped frame 7, it will form a rotational support for the feeding box 10 under the transmission cooperation of the transmission plate 19 and the transmission cover 18. Therefore, the feeding box 10 can be turned downward and tilted so that the position of the hopper 21 corresponds to that of the feeding trough 29. At the same time, when the feeding box 10 turns downward, the transmission plate 19 and the transmission cover 18 will slide, compressing the compression spring 20 and keeping the compression spring 20 in a stressed state. Therefore, when pushing the feeding box 10 upward for reset, the stressed compression spring 20 can use its own elastic force to push the transmission cover 18 and the transmission plate 19 to move in the reverse direction, so as to conveniently adjust the feeding box 10 to the horizontal position for reset.

[0067] S3. When moving the blanking hopper 21 to a position corresponding to the feeding trough 29, at this time, the stepping motor 22 and the four driving motors 3 are started by operating the control display screen 27. When the stepping motor 22 operates, it can drive the rotating shaft 23 to rotate, thereby driving the sealing plate 25 to rotate and disengaging from the opening of the feeding box 10. At this time, the feed can flow out and fall into the feeding trough 29. At the same time, the stepping motor 22 can control the rotation angle of the sealing plate 25, so as to adjust the outflow rate of the feed. When the four driving motors 3 operate, they can drive the corresponding wheels 4 to rotate, so that the whole device can move in a straight line and at a constant speed along the ground rail 1, thereby evenly feeding the feed into the feeding trough 29 for the poultry animals on the breeding rack to eat;

[0068] S4. After the poultry animals finish eating, at this time, the electric push rod 39 is started by operating the control display screen 27 to run, and the cleaning plate 40 is moved into the feeding trough 29 to make the cleaning plate 40 fit the inner wall of the feeding trough 29. Then, the four driving motors 3 are started to drive the corresponding wheels 4 to rotate in the reverse direction, driving the whole device to move. In this way, under the driving action of the connecting rod 41, the connecting pipe 42 and the mounting shaft 36, the support frame 37 can be driven to move horizontally. At this time, the cleaning plate 40 can move horizontally in the feeding trough 29, so as to scrape and clean the feed residues falling into the feeding trough 29. When the feed residues move to generate a thrust on the cover plate 32, at this time, the cover plate 32 can rotate to make the discharge hole in an open state, so that the feed residues can be discharged from the discharge hole for collection.
