Description

Technical Field

[0001] The invention belongs to the field of factory silkworm breeding, and in particular relates to a brush system of a cocoon picking machine for factory breeding. Background Art

[0002] Silkworms, commonly known as silkworms, are one of the economic insects that feed on mulberry leaves and spin silk cocoons. They belong to the order Lepidoptera, family Bombyx mori. Silkworms originated in China. Their development temperature is 7-40℃, and the optimal temperature for breeding is 20-30℃. They are mainly distributed in temperate, subtropical and tropical regions.

[0003] The life of a silkworm goes through the process of silkworm egg, larva, silkworm baby, silkworm cocoon and silkworm moth, which takes more than 40 days in total. The silkworm baby that has just hatched from the egg is dark in color and is called "larva". It is covered with fine hairs, which will not be obvious after about two days. After the larva hatches, it will start to shed its skin after being fed for a period of time. The shed period lasts for about one day, which is called "hibernation". After molting once, it grows into a second-instar larva. The silkworm molts four times in total, and only when it becomes a fifth-instar larva does it start to spin silk and make cocoons. After the cocoons are completed, they are harvested.

[0004] Silkworms are generally raised in small bamboo frames. This small frame has a simple structure, is easy to manufacture, can be hand-woven, and is low-cost. Silkworm breeding is a fully artificial breeding method, which is achieved through manual operation from silkworm eggs to cocoons. This method is small-scale, has a low yield of silk cocoons, and is time-consuming and labor-intensive. With the development of society, relying solely on silkworm breeding cannot meet the demand for silk, so factory silkworm breeding came into being. The existing factory silkworm breeding is small-scale, especially in the cocoon picking process. The existing cocoon picking methods are all manual or semi-automatic. Manual cocoon picking is extremely slow and has low efficiency. Semi-automatic cocoon picking is more difficult to operate, has a higher probability of failure, and has low cocoon picking efficiency.

[0005] Therefore, automated cocoon picking equipment came into being. These automated cocoon picking equipment are equipped with a structure that directly picks cocoons from cocoon cages and clusters. The cocoon picking structure is the core component of the cocoon picking equipment and directly affects the cocoon picking efficiency. The existing cocoon picking structures include extrusion type, ejection type and toothed structure. In actual cocoon picking, it is found that these cocoon picking structures are inefficient, there are many residual cocoons in cocoon cages and clusters, and the cocoon picking effect is poor. Summary of the invention

[0006] The purpose of the present invention is to provide a brush system for a cocoon picking machine for factory breeding, which adopts a brush-type cocoon picking structure and scrapes the cocoons from the cocoon cage in a rotating brush manner. The implementation method is simple and can act on each cocoon, with a significant cocoon picking effect. A systematic layout is performed to carry out orderly multiple cocoon picking on the cocoon cage and the cluster tool, which greatly improves the cocoon picking efficiency. After the cocoons are picked, there are very few residual cocoons in the cocoon cage and the cluster tool, and the cocoon picking effect is further improved.

[0007] In order to solve the above technical problems, the following technical solutions are adopted:

[0008] A brush system for a cocoon picking machine for factory farming includes a brush group, which is characterized in that the brush group includes an upper brush unit and a lower brush unit, and the upper brush unit and the lower brush unit are arranged in parallel and cooperate with each other.

[0009] Furthermore, the brush system includes 2-8 groups of brushes. The present invention realizes multiple cocoon picking from the cocoon cage by setting multiple groups of brushes. During the multiple cocoon picking processes, the cocoons are thoroughly scraped off the cocoon cage, and there is no cocoon in the cocoon cage after the cocoon picking, and the cocoon picking effect is significant.

[0010] Furthermore, the brush groups are arranged in a brush step with 2-3 brushes, the brush group spacing in the same brush step is 10-850mm, and the spacing between brush steps is 40-2500mm. The brush groups of the present invention are arranged in a plurality of brush steps to achieve step-by-step scraping of the cocoon cage, which, on the one hand, avoids the problem that the cocoons cannot be scraped off smoothly due to the close arrangement of the brush groups (easy to adhere to the brushes), and on the other hand, gives the cocoons a certain buffer time to prevent the cocoons from being damaged due to multiple scrapings.

[0011] Furthermore, the brush set also includes a brush tensioning mechanism, and the upper brush unit and the lower brush unit are fixed by the brush tensioning mechanisms on both sides, and the brush tensioning mechanism provides tensioning force to the upper brush unit and the lower brush unit. The brush tensioning mechanism provides tensioning force to the upper brush unit and the lower brush unit to prevent the two brush units from slipping, deflecting, and other problems during rotation, and keep the brush units running smoothly.

[0012] Furthermore, the brush tensioning mechanism includes a guide rail mounting plate, a guide rail, a slider and a bearing seat. A guide rail is installed in the guide rail mounting plate, a slider is provided on the guide rail, a bearing seat is installed on the slider, and two bearing seats are provided, which are respectively connected to the upper brush unit and the lower brush unit; the bearing seats are connected to tensioning bolts, which penetrate the guide rail mounting plate and then connect to the bearing seat. The brush tensioning mechanism of the present invention is composed of a guide rail mounting plate, a guide rail, a slider, a bearing seat and a tensioning bolt. The guide rail and the slider provide a certain buffer for the brush unit, and can quickly rebound and recover after displacement; the tensioning bolt grips the brush unit by gripping the bearing seat, providing tensioning force, preventing the brush unit from slipping, deflecting and other problems during rotation, and keeping the brush unit running smoothly. The structure is simple and has a good tensioning effect. Compared with other tensioning mechanisms, the operation of the brush unit is more stable.

[0013] Furthermore, a bearing seat mounting plate is installed between the bearing seat and the slider, and the tensioning bolt is connected to the bearing seat mounting plate. The bearing seat mounting plate is installed on the bearing seat, and the installation is stable; and the tensioning force of the tensioning bolt can be transmitted to the bearing seat.

[0014] Furthermore, the upper brush unit and the lower brush unit both include a brush motor, a brush shaft, a brush roller and a brush, the brush motor is connected to the brush shaft, the brush shaft is equipped with a brush roller, and the brush roller is evenly equipped with brushes; both sides of the brush shaft are installed in corresponding bearing seats. The brush unit of the present invention is composed of a brush motor, a brush shaft, a brush roller and a brush, and the rotation of the brush motor is transmitted to the brush roller through the brush shaft, thereby driving the brush to rotate, and the structure is simple.

[0015] After optimization, the spacing between the upper brush unit and the lower brush unit is 1-32mm. The spacing between the upper brush unit and the lower brush unit is controlled so that the brush can touch all the cocoons on the cocoon cage, ensuring that the cocoon cage can pass through the brush group smoothly. Through multiple running tests, it was found that when the spacing is 1-32mm, the cocoon cage can pass through the brush group smoothly, the probability of failure is low; and a high cocoon collection rate can be maintained, and the cocoon collection effect is optimal.

[0016] Furthermore, the brush set also includes a hair-plucking rod. The upper brush unit and the lower brush unit are respectively equipped with a hair-plucking rod. The two ends of the hair-plucking rod are respectively fixed on the corresponding bearing seats. The hair-plucking rod crosses the brush. The hair-plucking rod is a fixed structure. During the rotation of the brush, the hair-plucking rod continuously moves the brush, and the cocoons adhered to the brush are removed, thereby solving the problem of the brush sticking to the cocoons. The structure is simple and practical.

[0017] Furthermore, the angle between the position where the plucking rod crosses the brush and the horizontal cross section of the brush unit is 8-30 degrees, wherein the brush unit is an upper brush unit or a lower brush unit; the plucking rod can be located above or below the horizontal cross section. The plucking rod is arranged at the above position, which has a good plucking effect on the one hand, and the cocoons will not be adhered to again, and on the other hand, it will not affect the entry of the cocoon cage.

[0018] The above technical solution has the following beneficial effects:

[0019] The present invention is a brush system for a cocoon picking machine for factory farming, which adopts a brush-type cocoon picking structure to scrape the cocoons off the cocoon cage in a rotating brush manner. The implementation method is simple, and it can act on each cocoon, with a significant cocoon picking effect. It is also systematically arranged to carry out multiple orderly cocoon picking on the cocoon cage and the cluster tool, which greatly improves the cocoon picking efficiency. After the cocoon picking, there are very few residual cocoons in the cocoon cage and the cluster tool, and the cocoon picking effect is further improved. The specific beneficial effects are shown in the following points:

[0020] 1. The brush system of the present invention is composed of a brush group, which is composed of an upper brush unit and a lower brush unit. When the cocoon cage passes, the two brush units clamp the cocoon cage; the cocoons above and below the cocoon cage are continuously scraped and swept by synchronous rotation. In the relative movement of the cocoon cage and the brush unit, the scraping effect is better. The brush of the present invention can penetrate into the concave part of the cocoon cage, draw the cocoons out of the concave part, and collect the cocoons more thoroughly. Compared with the existing cocoon collecting mechanism, the cocoon collecting efficiency and effect are significantly improved.

[0021] 2. The present invention realizes multiple cocoon picking from the cocoon cage by arranging multiple groups of brush groups. During the multiple cocoon picking processes, the cocoons are thoroughly scraped and swept off the cocoon cage. After the cocoons are picked, there is no cocoon in the cocoon cage, and the cocoon picking effect is remarkable.

[0022] 3. The brush tensioning mechanism of the present invention is composed of a guide rail mounting plate, a guide rail, a slider, a bearing seat and a tensioning bolt. The guide rail and the slider provide a certain buffer for the brush unit, and can quickly rebound after displacement; the tensioning bolt grips the brush unit by gripping the bearing seat, providing tensioning force to prevent the brush unit from slipping, deflecting and other problems during rotation, and keep the brush unit running smoothly. The structure is simple and has a good tensioning effect. Compared with other tensioning mechanisms, the brush unit runs more stably.

[0023] 4. The plucking rod is a fixed structure. During the rotation of the brush, the plucking rod continuously plucking the brush, and the cocoons adhering to the brush are removed, thus solving the problem of the brush sticking to the cocoons. The structure is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS
