Description

Technical Field

[0001] This utility model relates to the field of screening equipment. More specifically, this utility model relates to a chestnut screening device with a circulating screening function. Background Technology

[0002] Chestnut, also known as: chestnut (common name), kuili (Hebei and other provinces), hairy chestnut (Henan), wind chestnut (Guangdong).

[0003] In the process of chestnut processing, a screening device is required to screen the chestnuts. Existing screening devices simply pour chestnuts onto a screen plate repeatedly, resulting in only one screening pass per chestnut. This leads to poor screening efficiency and difficulty in thoroughly screening the chestnuts. Furthermore, existing screening devices require replacing the screen plate with one of different mesh sizes to screen chestnuts of varying sizes, further complicating the ease of use of the device. Therefore, this invention designs a chestnut screening device with a circulating screening function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a chestnut screening device with a cyclic screening function to solve the problems of poor screening effect and poor ease of use of existing screening devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chestnut screening device with a circulating screening function, comprising a support frame, an outer cylinder rotatably connected to the support frame, a first motor fixedly connected to the support frame, one end of the output shaft of the first motor fixedly connected to the outer cylinder, a screen cylinder rotatably connected to the inner wall of the outer cylinder, a cylinder cover threadedly connected to one end of the screen cylinder, a rotating rod rotatably connected to the inner wall of the screen cylinder, multiple sets of material feeding plates fixedly connected to the circumferential side of the rotating rod, a second motor fixedly connected to the side of the screen cylinder, one end of the output shaft of the second motor fixedly connected to the rotating rod, four limiting blocks fixedly connected to the end face of the screen cylinder, and a fixing mechanism fixedly connected to the top of the outer cylinder.

[0006] Preferably, a receiving box is placed on the support, and a rotating wheel is fixedly connected to the screen cylinder and the cylinder cover.

[0007] Preferably, the fixing mechanism includes a support plate, which is fixed to the outer cylinder. A locking post is slidably connected to the surface of the support plate. A pull plate is fixedly connected to the top of the locking post. A spring is sleeved on the periphery of the locking post. The top of the spring is fixed to the pull plate, and the bottom of the spring is fixed to the support plate.

[0008] Preferably, the surface of the limiting block is provided with a limiting hole that cooperates with the locking post, and the locking post is inserted into the limiting hole.

[0009] Preferably, each group of the material feeding plates consists of four plates, and the multiple groups of material feeding plates are arranged in a crisscross pattern.

[0010] Preferably, the circumferential surface of the sieve cylinder is evenly divided into four parts, each of which has a sieve hole, but the diameter of the sieve hole in each of the four parts is different.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a screen cylinder and a material-pushing plate, uses a second motor to drive a rotating rod to rotate, which in turn drives the material-pushing plate to rotate. The material-pushing plate continuously pushes chestnuts from the bottom of the screen cylinder to the top, and then from the top back onto the screen cylinder, thereby enabling the chestnuts to be cyclically screened. This cyclical screening effectively improves the screening effect. Compared with existing screening devices where chestnuts are only screened once by the screen plate, this device significantly improves the screening effect.

[0013] 2. This utility model, through the design of the outer cylinder and the sieve cylinder, allows for the selection of chestnuts based on their size. By rotating the sieve cylinder, the portion with appropriately sized sieve holes is rotated to the bottom, while the other three parts of the sieve cylinder are blocked by the outer cylinder. Only the bottom part can be used for screening. In summary, according to the screening needs, only the rotation of the sieve cylinder is required to select the appropriate sieve hole. Compared to existing screening devices that require replacing sieve plates with different hole sizes, this screening device significantly improves ease of use. Attached Figure Description

[0027] Please see Figures 1-6This utility model provides a technical solution: a chestnut screening device with a circulating screening function, including a support 1, a receiving box 8 placed on the support 1, an outer cylinder 2 rotatably connected to the support 1, a first motor fixedly connected to the support 1, one end of the output shaft of the first motor fixedly connected to the outer cylinder 2, a screen cylinder 3 rotatably connected to the inner wall of the outer cylinder 2, a cylinder cover 4 threadedly connected to one end of the screen cylinder 3, a rotating wheel 9 fixedly connected to the screen cylinder 3 and the cylinder cover 4, the rotating wheel 9 being used to rotate the screen cylinder 3 and the cylinder cover 4, a rotating rod 5 rotatably connected to the inner wall of the screen cylinder 3, multiple sets of material-pulling plates 6 fixedly connected to the circumference of the rotating rod 5, each set of material-pulling plates 6 consisting of four, the multiple sets of material-pulling plates 6 being arranged in a crisscross pattern, a second motor fixedly connected to the side of the screen cylinder 3, one end of the output shaft of the second motor fixedly connected to the rotating rod 5, four limiting blocks 7 fixedly connected to the end face of the screen cylinder 3, and a fixing mechanism fixedly connected to the top of the outer cylinder 2.

[0028] Among them, such as Figure 1 and Figure 3 As shown, the fixing mechanism includes a support plate 10, which is fixed to the outer cylinder 2. A locking post 11 is slidably connected to the surface of the support plate 10. A pull plate 12 is fixedly connected to the top of the locking post 11. A spring is sleeved on the periphery of the locking post 11. The top of the spring is fixed to the pull plate 12, and the bottom of the spring is fixed to the support plate 10. A limiting hole is opened on the surface of the limiting block 7 to cooperate with the locking post 11. When the locking post 11 is located in the limiting hole, the outer cylinder 2 and the screen cylinder 3 are relatively fixed.

[0029] Among them, such as Figure 2 and Figure 6 As shown, the circumferential side of the sieve cylinder 3 is evenly divided into four parts, and each of the four parts is provided with a sieve hole. However, the diameter of the sieve hole on the four parts is different. Only the bottom part of the sieve cylinder 3 is exposed and not blocked by the outer cylinder 2. The other three parts of the sieve cylinder 3 are blocked by the outer cylinder 2.

[0030] The first motor drives the screen cylinder 3 to rotate, making the screen cylinder 3 vertically upward. Then, the cylinder cover 4 is removed, and the chestnuts are poured into the screen cylinder 3. The cylinder cover 4 is then installed back onto the screen cylinder 3, and the first motor is used to rotate the screen cylinder 3 back to a horizontal position. Figure 1 As shown, then, according to the screening requirements, i.e. the size of the chestnuts to be screened, first pull the pull plate 12 upward to move the locking post 11 out of the limiting hole, then rotate the screen cylinder 3 to rotate the part of the screen cylinder 3 with the appropriate screen hole size to the bottom, then release the pull plate 12, and under the action of the spring, the locking post 11 moves into the limiting block 7, thereby fixing the outer cylinder 2 and the screen cylinder 3 relatively. Then start the second motor, the second motor drives the rotating rod 5 to rotate, the rotating rod 5 drives the material feeding plate 6 to rotate, thereby using the material feeding plate 6 to continuously push the chestnuts from the bottom of the screen cylinder 3 to the top, and then from the top back onto the screen cylinder 3, thereby enabling the chestnuts to be screened in a cyclic manner. Through cyclic screening, the screening effect can be effectively improved.
