Description

Technical Field

[0001] The invention relates to the technical field of cocoon picking equipment, and in particular to a cocoon picking machine for sericulture. Background Art

[0002] After being raised and matured, silkworms usually make cocoons in a grid cluster. The grid cluster is generally a grid body with a number of grid holes formed by cross-connecting long strips of grid pieces horizontally and vertically. The silkworms make cocoons in the grid holes. When picking the cocoons, the cocoons are usually taken out from the grid holes one by one with fingers. This picking method is extremely inefficient and has high labor costs. In order to improve production efficiency, a variety of mechanized cocoon picking equipment has appeared on the market. The Chinese invention patent "Automatic cocoon picking system, automatic cocoon picking machine and cocoon picking method" (application number: CN201810920514.7, publication date: 2018.12. 18) discloses an automatic cocoon picking system, an automatic cocoon picking machine and a cocoon picking method, including a transmission centering module, which detects a grid cluster and transmits it; a visual recognition module, which is connected to the transmission centering module, collects the grid cluster image transmitted by the transmission centering module, and identifies the cocoons and the grid cluster frame; a transmission clamping module, which is connected to the visual recognition module, transmits, detects and clamps the grid cluster; a cocoon picking robot, which is arranged on the transmission clamping module to remove the cocoons from the grid cluster; and a control module, which communicates and controls the transmission centering module, the visual recognition module, the transmission clamping module and the cocoon picking robot. Although this patent can play the role of rapid cocoon picking, there are many existing grid cluster specifications, and different silkworm breeding factories will use grid clusters of different specifications. Therefore, its practicality is not high and it cannot meet the requirements of cocoon picking for grid clusters of different specifications. In addition, the grid clusters are not positioned during the transmission process, and the cocoon picking is prone to deviation and damage to the grid clusters, thereby increasing production costs.

[0051] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0052] Please refer to Figure 1-Figure 7This embodiment discloses a cocoon picking machine for silkworm breeding, including a frame 1, a punching assembly 2, a cocoon picking assembly 3, a positioning assembly 4 and a cocoon collecting box 5. Among them, a hollow area for picking cocoons is provided on the top plate of the frame 1, and a checkered plate 101 adapted to the grid cluster is provided at the bottom of the hollow area. The stamping assembly 2 is arranged on the top of the frame 1. The cocoon picking assembly 3 includes a mounting plate 31 arranged at the output end of the stamping assembly 2, a plurality of splicing blocks 32 arranged at the bottom of the mounting plate 31, and a plurality of cocoon picking forks 33 arranged at the bottom of the corresponding splicing blocks 32. The plurality of splicing blocks 32 are distributed in an array at the bottom of the mounting plate 31. Adjacent splicing blocks 32 can be spliced ​​and disassembled with each other, and are opposite to the grids on the grid cluster. The stamping assembly 2 is used to move the cocoon picking assembly 3 up and down to the central control area. Four positioning assemblies 4 are provided, and the four positioning assemblies 4 are respectively arranged on the front, rear, left and right sides of the central control area for positioning the grid cluster. The cocoon collecting box 5 is arranged on the frame 1 and is located below the hollow area.

[0053] In specific use, according to the specifications of the square cluster, a corresponding number of splicing blocks 32 are spliced. After splicing, the square cluster is placed in the corresponding position of the square plate 101 and the spliced ​​splicing block 32 group, and then the four sides of the square cluster are positioned by four positioning components 4. After positioning, the punching component 2 is started to drive the cocoon picking fork 33 to pick the cocoons on the square cluster, and the picked cocoons fall into the cocoon collecting box 6. After the cocoon picking is completed, the punching component 2 is reset, and then the empty square cluster is taken out and placed in the area where the positioning component 4 of another square cluster is positioned, and then the next cocoon picking operation is completed. The cocoon picking machine in this embodiment can splice different numbers of splicing blocks 32 according to square clusters of different specifications, and then adapt to square clusters of different specifications. There is no need to replace the cocoon picking machine, which reduces production costs and improves work efficiency. The device has high practicality and cost performance.

[0054] In this embodiment, the frame 1 is composed of four supporting legs, four cross bars and a top plate. The four supporting legs are arranged at the four corners of the bottom of the top plate. The four cross bars are respectively connected to the adjacent supporting legs. The hollow area is a rectangular through hole in the middle part of the top plate. The four positioning components 4 are respectively located on the four sides of the rectangular through hole, and the cocoon collecting box 5 is slidably connected to the cross bars. When the cocoon collecting box 5 is full of cocoons, it can be pulled out and replaced; more preferably, a handle 51 is provided on the outside of the cocoon collecting box 5 to facilitate pulling out and replacement.

[0055] Please refer to Figure 3The splicing block 32 includes a block body 321, and plug connectors 322 are provided on the top and bottom of the block body 321. The mounting plate 31 is provided with a plurality of plug holes 311 in an array, and the plug connectors are tightly matched with the plug holes 311. The four sides of the block body 321 are respectively provided with the same grooves 323 and protrusions 324, and the grooves 323 and the protrusions 324 are both dovetail-shaped, and the protrusions 324 can be inserted into the grooves 323 and tightly matched after insertion. The grooves 323 and the protrusions 324 are reversely connected, and the connecting sides are collinear. The grooves 323 and the protrusions 324 between the two adjacent surfaces are arranged the same.

[0056] When splicing, adjacent block bodies 321 are plugged in up and down, and corresponding protrusions 324 are inserted into corresponding grooves 323, and spliced ​​with each other as an example, and then a splicing block 32 corresponding to the number of square clusters is spliced, so as to adapt to square clusters of different specifications, and the splicing method is simple and easy to operate. In this embodiment, the plug connector 322 is a buckle, and the buckle is buckled into the plug hole 311. After the protrusion 324 and the groove 323 are completely spliced, the buckle is just buckled into the plug hole 311, thereby improving the stability of the splicing of the splicing block 32, preventing the cocoon picking fork 33 from falling during the cocoon picking process, and improving the efficiency of cocoon picking.

[0057] Please refer to Figure 8-Figure 10 Specifically, a cross slot 325 is provided at the bottom of the splicing block 32, a sliding block 326 is slidably connected in the cross slot 325, a threaded rod 331 is provided at the top of the cocoon picking fork 33, a threaded hole 3261 matching the threaded rod 331 is provided on the sliding block 326, and the splicing block 32 and the cocoon picking fork 33 are fixedly connected through the threaded rod 331 and the threaded hole 3261. Through the provision of the cross slot 325, the cocoon picking fork 33 can move forward, backward, left, and right relative to the splicing block 32, thereby adjusting the distance between adjacent splicing blocks 32, so that the device can adapt to square clusters of different spacings or sizes, thereby improving the practicality of the device. During specific adjustment, the threaded rod 331 can be screwed into the threaded hole 3261, and then the distance between adjacent cocoon picking forks 33 can be adjusted front, back, left and right according to actual conditions. After the specific adjustment, the cocoon picking fork 33 is rotated first so that the threaded rod 331 is completely screwed into the threaded hole 3261. At this time, the cocoon picking fork 33 is completely abutted against the splicing block 32, thereby fixing the cocoon picking fork 33 and the splicing block 32.

[0058] Please refer to Figure 1 The stamping assembly 2 includes a mounting frame 21 arranged on the top of the frame 1, a linear driving unit 22 arranged on the top of the mounting frame 21, and a linear guide rod 23 arranged between the mounting frame 21 and the frame 1. The output end of the linear driving unit 22 is transmission-connected to the mounting plate 31, and the linear guide rod 23 passes through the mounting plate 31.

[0059] In this embodiment, the mounting frame 21 has the same structure as the frame 1, and the linear drive unit 22 is arranged at the bottom of the top plate of the mounting frame 21. The linear drive unit 22 can be a linear driving mechanism such as an electric push rod, a cylinder, or an oil cylinder. Four linear guide rods 23 are provided, and the four linear guide rods 23 are arranged at the four corners of the mounting plate 31. The four linear guide rods 23 can enable the cocoon picking assembly 3 to move up and down stably.

[0060] Please refer to Figure 4-Figure 6 The positioning assembly 4 includes a positioning plate 41, a push rod 42, a toggle block 43, a cross plate 44 and a connector 45. The positioning plate 41 is arranged in the hollow area and can move back and forth linearly relative to the central control area. One end of the push rod 42 is connected to the positioning plate 41, and the other end is inserted into the linear guide hole 102 arranged in the top plate. One end of the toggle block 43 is connected to the other end of the push rod 42, and the other end penetrates and extends to the top of the top plate. A linear guide groove 103 connected to the linear guide hole 102 is arranged on the top of the top plate. The toggle block 43 is slidably connected in the linear guide groove 103. The cross plate 44 is arranged at the other end of the toggle block 43. A positioning hole 441 is arranged on the top of the cross plate 44. A plurality of plug holes 104 opposite to the positioning hole 441 are arranged on the top plate at intervals. The connector 45 can be inserted into the plug hole 104 from the positioning hole 441 on the cross plate 44 to position the positioning plate 41.

[0061] When the square cluster needs to be positioned, the push rod 42 is driven by the toggle block 43 to push the positioning plate 41 to move toward the square cluster. When the positioning plate 41 abuts against the square cluster, the plug-in 45 is inserted into the positioning hole 441 and the socket 104 to lock the position of the positioning plate 41, which is simple and convenient to operate. The socket 104 is provided with two rows, and the two rows of sockets 104 are symmetrically distributed on the top plate along the rotation axis of the push rod 42. The positioning holes 441 are provided with two, and the two positioning holes 441 are symmetrically distributed on the cross plate 44 along the rotation axis of the push rod 42. In this way, the positioning is more stable, making the square cluster more stable when picking cocoons, improving the efficiency of picking cocoons, and avoiding the situation where the cocoon picking fork 33 damages the square cluster during the cocoon picking process. The interval of the socket 104 is equal to the square side length of the square cluster, so that it is more convenient to adjust. When the specifications of the square cluster are known in advance, the positioning plate 41 can be adjusted in advance to improve work efficiency. Specifically, the connector 45 is a bolt, and the insertion hole 104 is a threaded hole corresponding to the bolt, which makes the fixation convenient and stable, thereby improving the stability of positioning.

[0062] The positioning assembly 4 also includes two guide rods 46, which are symmetrically arranged at both ends of the positioning plate 41. The ends of the two guide rods 46 away from the positioning plate 41 penetrate and extend into the guide holes 105 on the top plate. The guide rods 46 can provide positioning for the movement of the positioning plate 41, and will not shake left and right after positioning, further improving the stability of positioning. A limiting block 461 is provided at one end of the guide rod 46 located inside the guide hole 105 to limit the guide rod 46 from being pulled out of the guide hole 105, thereby preventing the guide rod 46 from being pulled out of the guide hole 105 and improving safety.

[0063] Please refer to Figure 7 The silkworm cocoon picking machine also includes a shearing assembly 6 disposed below the top plate, and the shearing assembly 6 includes a driving mechanism 61 and a shearing blade 62. The driving mechanism 61 is disposed below the top plate, specifically on the supporting legs, and the shearing blade 62 is transmission-connected to the output end of the driving mechanism 61, and the driving mechanism 61 drives the shearing blade 62 to move back and forth on the bottom surface of the lattice plate 101. The shearing assembly 6 can cut off the cocoons that are pushed out of the lattice plate 101 and have not fallen into the cocoon collecting box 5, and then fall into the cocoon collecting box 5, thereby improving the efficiency of cocoon picking.

[0064] Specifically, the driving mechanism 61 includes a driving motor 611, an output shaft 612, a transmission shaft 613, four transmission wheels 614 and a transmission belt 615. The driving motor 611 is arranged on the supporting foot at the bottom of the frame 1, the output shaft 612 is arranged below the top plate and is connected to the driving motor 611 in transmission, the transmission shaft 613 is arranged below the top plate, the transmission shaft 613 is arranged in parallel with the output shaft 612, and the distance between the transmission shaft 613 and the output shaft 612 is greater than the length of the lattice plate 101. The four transmission wheels 614 are respectively arranged at the two ends of the output shaft 612 and the transmission shaft 613, and two transmission belts 615 are provided, each of which is arranged on the transmission wheel 614 at the same end of the transmission shaft 613 and the output shaft 612, and the shear blade 62 is arranged between the two transmission belts 615.

[0065] In this embodiment, four transmission wheels 614 are respectively arranged on the inner sides of four supporting feet. The transmission wheels 614 can be gears or pulleys. When the transmission wheel 614 is a gear, the transmission belt 615 is a belt with inner teeth; when the transmission wheel 614 is a pulley, the transmission belt 615 is a belt. The driving motor 611 drives the output shaft 612 to rotate, and then the transmission shaft 613 is rotated under the action of the transmission wheel 614 and the transmission belt 615, thereby driving the shear blade 62 to move back and forth at the bottom of the grid plate 101 to cut the cocoons.

[0066] In summary, in this embodiment, different numbers of splicing blocks 32 can be spliced ​​according to corresponding grid clusters to perform cocoon picking operations on grid clusters of different specifications, and then the grid clusters can be positioned by four positioning components 4, so that the cocoon picking fork 33, the grid cluster and the grid holes on the grid plate 101 correspond one to one, and then the stamping component 2 is used to drive the cocoon picking fork 33 to move downward to realize the cocoon picking function. It can match grid clusters of different specifications and has high practicality and cost-effectiveness.
