Description

Technical Field

[0001] This utility model relates to the field of silkworm breeding equipment technology, and in particular to an automated track-type silkworm feeding device. Background Technology

[0002] When silkworms are raised on a large scale using traditional manual feeding methods, feeding platforms need to be built above the breeding area, with one platform every few meters. Workers need to carry mulberry leaves onto each platform and scatter them evenly over the entire breeding area. This process is not only time-consuming but also physically demanding, resulting in low efficiency and hindering large-scale silkworm farming. Furthermore, manually scattering leaves while walking may not allow workers to keep an eye on the silkworms, potentially leading to trampling or injury. Therefore, this application designs an automated track-type silkworm feeding device to solve the technical problems caused by the aforementioned manual feeding methods. Utility Model Content

[0003] This invention provides an automated track-type silkworm feeding device that replaces manual leaf spreading, improves feeding efficiency, and avoids harming silkworms.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Furthermore, the bottom periphery of the leaf feeding box is inclined to form a conical structure in the direction of the leaf outlet.

[0010] Furthermore, the leaf feeding frame has a square frame structure, and two second tracks are spaced apart at the top of the leaf feeding frame along its length. Each of the four corners of the bottom of the leaf feeding frame is rotatably connected to a first traveling wheel, and the rotational tangential direction of each second traveling wheel is consistent with the arrangement direction of the first tracks. The two first traveling wheels in the width direction of the bottom of the leaf feeding frame are connected by a first rotating shaft, which is parallel to the second tracks. A first drive motor is provided on the leaf feeding frame, and the first drive motor is connected to one of the first rotating shafts to drive the corresponding two first traveling wheels to rotate. The positions of the two first traveling wheels located in the same width direction of the leaf feeding frame correspond one-to-one, and they travel together along a corresponding first track.

[0011] Furthermore, the first track includes several track sections, each track section including a supporting crossbeam and three supporting vertical beams. The supporting vertical beams are I-shaped structures. The center line of the top of the supporting crossbeam protrudes upward to form a guide rail.

The belt elevator is divided into a parallel section and a ramp section. The parallel section is fixedly installed at the bottom of the leaf storage hopper, and the ramp section extends obliquely out of the conveying hole and into the area where the first track is located.

[0013] The beneficial effects of this utility model are:

[0014] 1) The leaf feeding cart is set up in the silkworm rearing area via a first track and a feeding cart frame. The feeding cart frame moves back and forth along the first track, and the feeding cart moves back and forth left and right along the feeding cart frame, thus realizing the movement of the feeding cart in all directions. During the movement, the feeding cart evenly scatters mulberry leaves onto the ground, thereby completing the automatic silkworm feeding work in a certain area. The automatic walking feeding of silkworms by the feeding cart on the track replaces manual feeding, which can not only improve the feeding efficiency and reduce the intensity of manual work, but also avoid damage to the silkworms, and solve the objective technical problems existing in traditional manual silkworm feeding. Since the feeding cart itself is relatively high, it is not easy for people to add mulberry leaves manually. In order to solve this problem, this utility model adds an automatic leaf loading mechanism. The operator only needs to pour the mulberry leaves to be fed into the leaf storage hopper, and the mulberry leaf conveying mechanism completes the fixed-point automatic feeding work on one side of the first track, further reducing the intensity of manual work.

[0015] 2) When the leaf-discharging drive motor drives the leaf-discharging roller to rotate slowly and uniformly, a certain amount of mulberry leaves are carried onto the conveyor belt through the gap between two adjacent leaf-discharging blades. The conveyor belt then drives the conveyor roller to rotate through the leaf-spreading drive motor, which in turn drives the conveyor belt to rotate. The conveyor belt receives the mulberry leaves coming out of the leaf outlet and sends them away in a timely manner to prevent the mulberry leaves from accumulating at the leaf outlet. The conveyor belt transports the mulberry leaves to the rear of the leaf-feeding car frame in the forward direction, and the mulberry leaves are evenly scattered during the movement of the leaf-feeding car frame and the leaf-feeding car. By controlling the speed of the leaf-discharging drive motor and the speed of the conveyor belt, the amount of mulberry leaves scattered can be adjusted, so that the leaf-feeding car can scatter an appropriate number of mulberry leaves during the movement, avoiding an excessive or uneven amount of mulberry leaves.

[0016] 3) The main function of the leaf feeding cart frame is to drive the leaf feeding cart to move in the forward and backward directions, and to stop at a fixed point on the first track through the first limit switch. Several second limit switches are set at intervals on the leaf feeding cart frame. The second limit switches enable the leaf feeding cart to stop at a fixed point in the left and right directions. The first limit switch and the second limit switch control the sequence of the leaf feeding cart's movement. First, it moves forward along the first track, then moves horizontally along the leaf feeding cart frame, and then turns back along the first track. This cycle repeats until the entire aquaculture area is traversed, and finally it returns to the original point to receive the automatic leaf replenishment work of the automatic leaf feeding mechanism.

[0017] 4) The segmented track body is more convenient for handling and disassembly. It can be assembled according to the required track length. At the same time, the track body is supported by a certain height through the support beam, so that the leaf feeding car frame has a certain height difference with the ground, avoiding contact with the silkworms.

[0031] Reference Figures 1 to 7As shown, an automated track-type silkworm feeding device includes a leaf feeding cart 1, a leaf feeding cart frame 2, a leaf feeding track 3, and an automatic leaf loading mechanism 4. The leaf feeding track 3 includes two parallel and spaced first tracks 31. The leaf feeding cart frame 2 is distributed perpendicular to the two first tracks 31. The bottom sides of the leaf feeding cart frame 2 are provided with first traveling wheels 21. The leaf feeding cart frame 2 moves along the first tracks 31 via the first traveling wheels 21 to drive the leaf feeding cart frame 2 to reciprocate. The top of the leaf feeding cart frame 2 is provided with a second track 22 distributed perpendicular to the two first tracks 31, and the bottom of the leaf feeding cart 1 is provided with the second track 22. The leaf feeding cart 1 is equipped with a second traveling wheel 15, which travels along the second track 22 to reciprocate between the two first tracks 31. The leaf feeding cart 1 is provided with a leaf feeding box 12 with a top opening, and a leaf discharging mechanism 13 is provided at the bottom of the leaf feeding box 12. The automatic leaf feeding mechanism 4 is located on one side of one end of one of the first tracks 31. The automatic leaf feeding mechanism 4 includes a leaf storage hopper 41 and a mulberry leaf conveying mechanism 42. One end of the mulberry leaf conveying mechanism 42 is installed at the bottom inside the leaf storage hopper 41, and the other end of the mulberry leaf conveying mechanism 42 is inclined upward and extends into the area of ​​the two first tracks 31. Specifically, the leaf feeding cart 1 is set up in the silkworm rearing area via the first track 31 and the leaf feeding cart frame 2. The leaf feeding cart frame 2 moves back and forth along the first track 31, and the leaf feeding cart 1 moves back and forth in the left and right directions along the leaf feeding cart frame 2, thereby realizing the movement of the leaf feeding cart 1 in all directions. During the movement, the leaf feeding cart 1 evenly scatters mulberry leaves onto the ground, thus completing the automatic silkworm feeding work in a certain area. The automatic movement of the leaf feeding cart 1 along the track replaces manual silkworm feeding, which can not only improve the efficiency of silkworm feeding and reduce the intensity of manual labor, but also avoid damage to silkworms and solve the objective technical problems existing in traditional manual silkworm feeding. Since the leaf feeding cart itself is relatively high, it is not easy for people to add mulberry leaves manually. In order to solve this problem, this utility model adds an automatic leaf loading mechanism 4. The operator only needs to pour the mulberry leaves to be fed into the leaf storage hopper 41, and the mulberry leaf conveying mechanism 42 completes the fixed-point automatic feeding work on one side of the first track 31, further reducing the intensity of manual labor.

[0032] Please refer to Figure 4As shown, the leaf feeding cart 1 includes a frame 11, a leaf feeding box 12, a leaf dispensing mechanism 13, a leaf spreading and conveying module 14, second traveling wheels 15, and a second drive motor 16. The frame 11 has a square frame structure. The leaf feeding box 12 is fixedly connected to the top of the frame 11. Each of the four corners of the bottom of the frame 11 is rotatably connected to a second traveling wheel 15. The rotational tangential direction of each second traveling wheel 15 is consistent with the arrangement direction of the second track 22. Two second traveling wheels 15 located on the same side of the width direction of the frame 11 are connected by a second rotating shaft 17. The second drive motor 16 is fixed. The second drive motor 16 is connected to one of the second rotating shafts 17 on the frame 11 to drive the two corresponding second traveling wheels 15 to rotate. The two second traveling wheels 15 located on the same length direction of the frame 11 are in one-to-one correspondence and travel together along a corresponding second track 22. The bottom of the leaf feeding box 12 is provided with a leaf outlet, and the leaf outlet mechanism 13 is installed at the leaf outlet. The leaf spreading and conveying module 14 is installed on the frame 11 and located below the leaf outlet. The leaf spreading and conveying module 14 is used to spread the mulberry leaves conveyed by the leaf outlet mechanism onto the ground. Specifically, the leaf spreading and conveying module 14 includes two conveying rollers, a conveyor belt 141, and a leaf spreading drive motor 142. The two conveying rollers are parallel and spaced apart in the horizontal direction and are rotatably connected to the frame 11. The conveyor belt 141 is wound around the two conveying rollers. The leaf spreading drive motor 142 is fixedly connected to the frame 11 and is drivenly connected to one of the conveying rollers. The leaf-spreading drive motor 142 drives the conveyor roller to rotate, which in turn drives the conveyor belt 141 to rotate. The conveyor belt 141 receives the mulberry leaves coming out of the leaf outlet and conveys the mulberry leaves to the rear of the leaf feeding carriage 2 in the forward direction. Thus, as the leaf feeding carriage 2 moves, the leaf-spreading drive motor 142 evenly spreads the mulberry leaves. The leaf-spreading drive motor 142 adjusts its rotation direction according to the moving direction of the leaf feeding carriage 2, so that the conveyor belt 141 always spreads mulberry leaves behind the forward direction of the leaf feeding carriage 2, avoiding gaps in the leaf-spreading area.Considering that the conveyor belt 141 needs to evenly distribute mulberry leaves and the leaf outlet needs to control the number of leaves discharged each time, the leaf discharge mechanism 13 includes a leaf discharge roller 131 and a leaf discharge drive motor 132 to achieve the above functions. The leaf discharge roller 131 includes a central rotating shaft 1311 and several leaf discharge blades 1312. The several leaf discharge blades 1312 are distributed in a circle with equal angles around the axis of the central rotating shaft 1311. One side of each leaf discharge blade 1312 is fixedly connected to the outer peripheral wall of the leaf discharge roller 131 by bolts. The leaf outlet is a rectangular structure opened along the length of the leaf feeding box 12. The two ends of the central rotating shaft 1311 are rotatably connected to the two sides of the width of the leaf outlet. The leaf discharge drive motor 132 is installed on one side of the frame 11, and the output shaft of the leaf discharge drive motor 132 is drivenly connected to one end of the central rotating shaft 1311. When the leaf-discharging drive motor 132 drives the leaf-discharging roller 131 to rotate slowly and uniformly, a certain amount of mulberry leaves are carried onto the conveyor belt 141 through the spacing between adjacent leaf-discharging blades 1312. The leaves are then promptly transported away by the conveyor belt 141, preventing them from being squeezed at the leaf outlet. By controlling the rotation speed of the leaf-discharging drive motor 132 and the conveyor belt, the amount of mulberry leaves scattered can be adjusted, ensuring that the leaf-feeding cart 1 can scatter an appropriate number of mulberry leaves during its movement, avoiding excessive or uneven distribution of leaves. The bottom periphery of the leaf-feeding box 12 is inclined towards the leaf outlet to form a conical structure, facilitating the collection of mulberry leaves towards the outlet. The capacity of the leaf-feeding box 12 can be determined according to the silkworm rearing area and the amount of leaves required per feeding. The capacity needs to be sufficient for the leaf-feeding cart 1 to travel through the silkworm rearing area once, avoiding insufficient supply midway.

[0033] The leaf feeding frame 2 has a square frame structure. Two second tracks 22 are spaced apart along the length of the leaf feeding frame 2 at the top of the leaf feeding frame 2. Each of the four corners of the bottom of the leaf feeding frame 2 is rotatably connected to a first traveling wheel 21. The rotational tangential direction of each second traveling wheel 21 is consistent with the arrangement direction of the first track 31. The two first traveling wheels 21 in the width direction of the bottom of the leaf feeding frame 2 are connected by a first rotating shaft 23. The first rotating shaft 23 is arranged parallel to the second track 22. The leaf feeding frame 2 is provided with a first drive motor 24. The first drive motor 24 is connected to one of the first rotating shafts 23 to drive the corresponding two first traveling wheels 21 to rotate. The positions of the two first traveling wheels 21 located in the same width direction of the leaf feeding frame 2 are one-to-one, and they travel together along a corresponding first track 31. Each end of the first track 31 is provided with a first limit switch. The leaf feeding frame 2 is provided with several spaced second limit switches along its length. The second limit switches are used to locate the traveling position of the leaf feeding 1. Specifically, the main function of the leaf feeding carriage frame 2 is to drive the leaf feeding carriage 1 to move in the forward and backward directions, and to stop it at a fixed point on the first track 31 via a first limit switch. Several second limit switches are spaced apart on the leaf feeding carriage frame 2, which allow the leaf feeding carriage to stop at fixed points in the left and right directions. The sequence of movement of the leaf feeding carriage is controlled by the first and second limit switches, and the travel path is as follows: Figure 3 As shown by the arrows, the leaf feeding carriage 2 first moves forward along the first track 31, then the leaf feeding carriage 1 moves horizontally along the leaf feeding carriage 2, and then the leaf feeding carriage 2 turns back along the first track 31. This cycle repeats until the entire aquaculture area is traversed, and finally returns to the origin to receive automatic leaf replenishment from the automatic leaf feeding mechanism 4. The specific positions of the first limit switch and the second forming switch can be determined according to the actual situation.

[0034] Each first track 31 is composed of multiple track bodies 311 spliced ​​together. Each track body 311 includes a supporting crossbeam 3111 and three supporting vertical beams 3112. The supporting vertical beams 3112 have an I-shaped structure. The center line of the top of the supporting crossbeam 311 protrudes upward to form a guide rail 3113. The three supporting vertical beams 3112 are distributed at intervals at the bottom of the supporting crossbeam 3111. The top horizontal end of each supporting vertical beam 3113 is fixedly connected to the bottom of the supporting crossbeam 3111. The bottom horizontal end of each supporting vertical beam 3112 is fixedly connected to the ground by expansion screws. Each track body 311 is tightly connected end to end so that each guide rail 3113 is connected to form a straight line. The outer periphery of the first traveling wheel 21 is provided with a coaxially recessed limiting groove. The first traveling wheel travels in a straight line along the guide rail 3113 through the limiting groove. The first traveling wheel 21 has an H-shaped cross-section, and its limiting groove is engaged with the guide rail 3113 for guidance and limitation. The segmented track body 311 is more conducive to handling and disassembly, and can be assembled according to the required track length. At the same time, the track body 31 is supported by the supporting vertical beam 3112 to a certain height, so that the leaf feeding frame 2 has a certain height difference with the ground, avoiding contact with the silkworms.

[0035] The mulberry leaf conveying mechanism 42 is a belt conveyor. The bottom of the leaf storage hopper 41, facing the first track 21, has a conveying hole extending to the outside. The belt conveyor is divided into a parallel section and an inclined section. The parallel section is fixedly installed at the bottom of the leaf storage hopper 41, and the inclined section extends obliquely from the conveying hole to the area where the first track 21 is located. The belt conveyor uses a non-slip skirted inclined conveyor belt, and the angle between the parallel section and the inclined section is 135°. The leaf storage hopper 41 is an inverted isosceles trapezoidal structure. The shorter base of the isosceles trapezoid is the bottom of the leaf storage hopper 41, and the longer base is the top. The top is open to facilitate the collection of mulberry leaves to the bottom, which is beneficial for the conveying of mulberry leaves.
