Description

Technical Field

[0001] This utility model relates to the technical field of silkworm feeding devices, and in particular to a silkworm feeding device. Background Technology

[0002] Traditional silkworm rearing tools mostly consist of cardboard boxes or bamboo products. Silkworms are placed in rearing frames, and mulberry leaves are manually spread on top. This manual spreading of mulberry leaves is labor-intensive, inefficient, and cannot guarantee uniform thickness. In recent years, there have been reports in China of automated silkworm feeding devices, such as the automated feeding device for silkworm rearing disclosed in CN215557429U. However, this device requires manual pushing via casters, which presents operational inconvenience. Furthermore, feeding young silkworms requires cutting mulberry leaves into small pieces before feeding, and the amount of leaves must be adjusted according to the feeding needs of silkworms of different ages. Therefore, currently, manual feeding of young silkworms is the primary method in China, and no literature on automated silkworm feeding devices has been found. Utility Model Content

[0003] In order to solve the problems of low silkworm feeding efficiency and difficulty in controlling the amount of feed for young silkworms, the present invention adopts the following technical solution: a young silkworm feeding device, including a frame (1), a first hopper (3) and a second hopper (4), characterized in that: the first hopper (3) is horizontally fixedly connected on the frame (1), and the second hopper (4) is inclinedly fixedly connected above the rear side of the first hopper (3).

[0004] A first variable frequency motor (31) is fixedly connected to one side of the first hopper (3), and a first connecting shaft (33) is rotatably connected to the front end of the first hopper (3). A first circulating conveyor belt (5) is connected to the outside of the first connecting shaft (33). A large brush roller (15) is rotatably connected inside the first hopper (3), and the large brush roller (15) is located above the first circulating conveyor belt (5). The output end of the first variable frequency motor (31) is fixedly connected to one end of the corresponding first connecting shaft (33), and a second rotating shaft (13) is fixedly connected to the other end of the first connecting shaft (33). A second sprocket (14) is fixedly connected to the second rotating shaft (13). One end of the large brush roller (15) is fixedly connected to one end of the first rotating shaft (10), and a first sprocket (11) is fixedly connected to the first rotating shaft (10). The second sprocket (14) and the first sprocket (11) are driven by a first chain (12).

[0005] A second variable frequency motor (32) is fixedly connected to one end of the outer side of the second hopper (4), and a second connecting shaft (34) is rotatably connected to the front end of the second hopper (4). A second circulating conveyor belt (6) is connected to the outside of the second connecting shaft (34). A small brush roller (28) is rotatably connected to the front side inside the second hopper (4). The small brush roller (28) is located above the second circulating conveyor belt (6). The output end of the second variable frequency motor (32) is fixedly connected to one end of the corresponding second connecting shaft (34). A third rotating shaft (20) is fixedly connected to the other end of the second connecting shaft (34). A third sprocket (21) is fixedly connected to the third rotating shaft (20). A fourth rotating shaft (23) is fixedly connected to one end of the small brush roller (28). A fourth sprocket (24) is fixedly connected to the fourth rotating shaft (23). The third sprocket (21) and the fourth sprocket (24) are driven by a second chain (22).

[0006] Furthermore, the mulberry leaves fed into the second hopper (4) tend to concentrate in the middle of the bottom of the hopper. In order to disperse the mulberry leaves fed from the second hopper (4) to the first hopper (3), a spiral distribution rod (30) is rotatably connected inside the second hopper (4) behind the small brush roller (28). One end of the spiral distribution rod (30) is fixedly connected to a fifth rotating shaft (25). One end of the fifth rotating shaft (25) is fixedly connected to a fifth sprocket (26). The fifth sprocket (26) and the sixth sprocket (36) are driven by a third chain (27).

[0007] Furthermore, in order to make the mulberry leaves conveyed from the second hopper (4) to the first hopper (3) more evenly distributed, the spiral pattern on the spiral distribution rod (30) is a left spiral and a right spiral respectively from the middle of the spiral distribution rod (30) to both ends.

[0008] Furthermore, mulberry leaves fed into the second hopper (4) tend to concentrate in the middle of the bottom of the hopper. In order to achieve the effect of pre-dispersing the mulberry leaves, this utility model fixes the second hopper (4) at an angle to the upper rear side of the first hopper (3); preferably, the second hopper (4) forms a 30-degree angle with the bottom of the first hopper (3). Through the inclined surface of the second hopper (4), the mulberry leaves fed into the second hopper (4) are evenly distributed to a certain extent as they slide down to the bottom of the hopper under the action of gravity.

[0009] Furthermore, in order to monitor the amount of mulberry leaves in the first hopper (3) and the second hopper (4) in real time, a first infrared probe (19) is fixedly connected to one side inside the first hopper (3); and a second infrared probe (35) is fixedly connected to one side inside the second hopper (4).

[0010] Furthermore, in order to adjust the amount of mulberry leaves fed according to the feeding amount of silkworms of different ages, an adjustment component for adjusting the height of the large brush roller (15) is provided on each side of the first hopper (3); the adjustment component includes a mounting frame (7) fixedly connected to both sides of the first hopper (3); a connecting block (8) is slidably connected inside the mounting frame (7); a screw (9) is threadedly connected to the upper end of the mounting frame (7), and the bottom end of the screw (9) is rotatably connected to the upper end of the corresponding connecting block (8); the two ends of the connecting block (8) are rotatably connected inside the first rotating shaft (10). The distance between the large brush roller (15) and the first circulating conveyor belt (5) is adjusted by the adjustment component. The smaller the distance between the two, the smaller the amount of mulberry leaves passing through, and the larger the distance between the two, the larger the amount of mulberry leaves passing through.

[0011] Furthermore, support feet (2) are fixedly connected to the four corners of the bottom of the frame (1), and first reinforcing rods (16) are fixedly connected to the left and right sides of the frame (1). Second reinforcing rods (29) are fixedly connected laterally to the middle of the front and rear ends of the frame (1). When the silkworm feeding device of this utility model is started, the square silkworm frame containing the silkworms is carried by a conveyor belt between the second reinforcing rod (29) and the first circulating conveyor belt (5) and passes at a constant speed from the rear of the frame (1) to the front to catch the mulberry leaves falling from the first hopper (3). The above-mentioned conveyor belt and square silkworm frame are not technical features of this utility model, and will not be described in detail here. The same applies below.

[0012] Furthermore, since the square silkworm frame has a certain thickness at its edges, some of the mulberry leaves falling from the first hopper (3) will inevitably land on the edges of the silkworm frame, resulting in waste or pollution. In this invention, a connecting plate (17) is fixedly connected to the lower front end of the first hopper (3), and a cleaning brush (18) is fixedly connected to the bottom end of the connecting plate (17). When the square silkworm frame moves forward with the conveyor belt toward the frame (1), the cleaning brush (18) can clean the mulberry leaves that have fallen on the edges of the silkworm frame.

[0013] Furthermore, when designing the silkworm feeding device of this utility model, the inventor uses a combination of a large brush roller (15) and a small brush roller (28) to make it easier to control the amount of mulberry leaves fed; preferably, the diameter of the large brush roller (15) is 200mm; and the diameter of the small brush roller (28) is 100mm.

[0014] Furthermore, the surface of the second circulating conveyor belt (6) is provided with a grass-like texture to provide it with a certain degree of friction. The silkworm feeding device described in this invention can also be used normally when the mulberry leaves are relatively wet and slippery.

[0015] The working principle of the silkworm feeding device of this utility model is as follows: Mulberry leaves are continuously fed from directly above the second hopper (4), and the second variable frequency motor (32) is started at the same time. The second variable frequency motor (32) drives the second circulating conveyor belt (6) through the second connecting shaft (34), and drives the small brush roller (28) and the spiral feed rod (30) through the second chain (22) and the third chain (27) respectively. The mulberry leaves on the second circulating conveyor belt (6) are successively fed into the first circulating conveyor belt (5) in the first hopper (3) below through the spiral feed rod (30) and the small brush roller (28), and the first variable frequency motor (31) is started at the same time. The first variable frequency motor (31) drives the first circulating conveyor belt (5), and drives the large brush roller (15) through the first chain (12). Then the mulberry leaves on the first circulating conveyor belt (5) are fed into the silkworm frame of the frame (1) at a uniform speed through the large brush roller (15).

[0016] The beneficial effects of this invention are as follows: The silkworm feeding device described in this invention, through the above-described working principle, enables continuous and automated feeding of silkworms, is easy to operate, and saves manpower. During the operation of the silkworm feeding device, the rotation of the small brush roller brushes mulberry leaves exceeding the thickness back to the bottom of the second hopper, allowing only mulberry leaves of a certain thickness to fall onto the first circulating conveyor belt below. The first infrared probe monitors the amount of mulberry leaves on the first circulating conveyor belt in real time, and the second infrared probe monitors the amount of mulberry leaves in the second hopper. When the total amount of mulberry leaves in the second hopper exceeds the limit, feeding to the first hopper will stop, and both probes can be adjusted according to the required amount of mulberry leaves for different stages. The rotation of the large brush roller in this invention brushes mulberry leaves exceeding the thickness back for redistribution, allowing only mulberry leaves of the same thickness to fall evenly into the silkworm frames containing the silkworms below. Through the above technical means, the silkworm feeding device described in this invention can achieve precise feeding of silkworms. Attached Figure Description
