Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing, in particular to an impurity removing device for removing pepper stems of pepper raw materials. Background Art

[0002] Sichuan peppercorns are an important economic crop in my country. After being picked, they undergo several processes, including sun drying or drying, seed removal, screening, and selection, before they can be used.

[0003] In the process of screening peppercorns, it is necessary to separate the peppercorns from the peppercorn stalks to achieve the purpose of removing impurities. A small amount of peppercorns can be removed manually. Generally, the peppercorns are shaken with a dustpan. Under the action of gravity, the peppercorns will roll down, while the light peppercorn stalks will stay on top, which can also achieve the purpose of removing impurities from the peppercorns.

[0004] However, with the continuous development of mechanical equipment, when the amount of pepper is large, the manual method is difficult to meet the efficiency of removing impurities from the pepper. Nowadays, mechanical equipment that shakes the pepper with a dustpan to remove impurities is also common. The pepper is placed on the conveyor belt with an inclined setting, so that the pepper slides down on the conveyor belt, and the pepper stems run with the conveyor belt, which can also achieve the purpose of removing impurities from the pepper.

[0005] However, existing equipment cannot adjust the inclination of the conveyor belt, resulting in the inability to adjust the angle according to the actual situation of the pepper when removing impurities. For example, the dryness of the pepper varies, and the speed of the conveyor belt varies. Adjusting the corresponding inclination angle can help improve the effect of removing impurities from the pepper. Therefore, it is urgent to design an impurity removal device for removing the stems of the pepper raw material to solve the above problem. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5As shown, an embodiment of the present invention provides an impurity removal device for removing peppercorn stalks from peppercorn raw materials, comprising a support frame 1, with driven rollers 2 and active rollers 3 provided on both sides of the top of the support frame 1, respectively, and the driven rollers 2 and the active rollers 3 are externally connected to a screening belt 7 for transmission and screening of the peppercorns; columns 9 are fixedly provided on the outer walls on both sides of the support frame 1, and a material box 10 is provided on the top of the columns 9, and the material box 10 is at least used for storing the peppercorns; support rods 13 are fixedly provided on the outer walls on both sides of the support frame 1, and an adjusting mechanism 14 is provided on the top of the support rod 13, and the adjusting mechanism 14 is at least used for adjusting the inclination angle of the screening belt 7; a positioning component 15 is provided on the top of the support rod 13, and the positioning component 15 is at least used for positioning and locking the adjusting mechanism 14.

[0030] In this embodiment, a support frame 1 is included, and a driven roller 2 and an active roller 3 are respectively provided on both sides of the top of the support frame 1. The external transmission of the driven roller 2 and the active roller 3 is connected to a screening belt 7. The screening belt 7 is at least used for conveying and screening the peppercorns. The peppercorns fall from top to bottom on the screening belt 7. Under the action of gravity, the peppercorns will roll down along the screening belt 7, while the lighter peppercorn stalks will move upward with the screening belt 7, thereby achieving the effect of removing impurities from the peppercorn stalks.

[0031] In this embodiment, columns 9 are fixedly provided on the outer walls of both sides of the support frame 1, and a material box 10 is provided on the top of the column 9. The material box 10 is at least used for storing peppercorns;

[0032] An adjustment hole 11 is provided on the top of the column 9, and a hoist 12 for vertically transporting the peppercorns is provided on one side of the material box 10. The peppercorns at a lower position can be transported to the material box 10 at a higher position through the hoist 12, thereby realizing a convenient loading function.

[0033] In this embodiment, support rods 13 are fixedly provided on the outer walls of both sides of the support frame 1, and an adjustment mechanism 14 is provided on the top of the support rod 13. The adjustment mechanism 14 is at least used to adjust the inclination angle of the screening belt 7;

[0034] Specifically, the adjustment mechanism 14 includes a rotating disk 20, a synchronization rod 17 is provided between the two rotating disks 20, and elastic support members 16 are fixedly provided on both sides of the rotating disk 20. The end of the elastic support member 16 is installed with a shaft sleeve 18, and the shaft sleeve 18 is provided with a transmission roller 19 that contacts the screening belt 7. The end of the synchronization rod 17 is provided with a tool hole 22. The operator can use a tool such as a hexagonal wrench to insert it into the tool hole 22, let the hexagonal wrench drive the synchronization rod 17 to rotate, and use the synchronization rod 17 to drive the rotating disk 20 to rotate, thereby adjusting the angle between the elastic support member 16 and the screening belt 7 to adjust the inclination angle of the screening belt 7;

[0035] Specifically, the elastic support member 16 includes a sleeve 25 fixedly mounted on the rotating disk 20, and a spring 27 is provided inside the sleeve 25. A telescopic rod 26 is slidably inserted into the temporal portion of the sleeve 25, and the end of the telescopic rod 26 is fixedly connected to the shaft sleeve 18. As the rotating disk 20 rotates, the elastic support member 16 changes the relative length of the telescopic rod 26 and the sleeve 25 under the action of the spring 27, ensuring that the transmission roller 19 can always contact and transmit with the screening belt 7. When the rotating disk 20 rotates clockwise, the inclination angle of the screening belt 7 becomes smaller, and vice versa, the inclination angle of the screening belt 7 becomes larger.

[0036] In this embodiment, a positioning assembly 15 is provided at the top end of the support rod 13, and the positioning assembly 15 is at least used to achieve positioning and locking of the adjustment mechanism 14;

[0037] Specifically, the positioning assembly 15 includes a fixed disk 21 fixedly mounted on the top of the support rod 13. The fixed disk 21 and the rotating disk 20 are distributed in parallel. The fixed disk 21 and the rotating disk 20 are both provided with a number of equidistant and annularly distributed sockets 23. The number of sockets 23 is preferably 12, and an insertion rod 24 is provided inside the socket 23. When adjusting the position of the elastic support member 16, the operator first pulls out the insertion rod 24 from the inside of the socket 23 so that the rotating disk 20 and the fixed disk 21 can rotate relative to each other. After the position adjustment of the elastic support member 16 is completed, the operator inserts the insertion rod 24 into the corresponding socket 23 to achieve re-locking between the rotating disk 20 and the fixed disk 21.

[0038] The utility model provides a de-impurity device for removing the stems of Sichuan pepper raw materials. The device adopts an adjusting mechanism 14, which can change the contact point between the transmission roller 19 and the screening belt 7 by rotating the adjusting mechanism 14, thereby changing the inclination angle of the screening belt 7 to achieve the de-impurity function of the Sichuan pepper under different actual conditions.

[0039] In this embodiment, a reducer 4 and a driving member 5 mounted on the support frame 1 are provided on one side of the active roller 2. The reducer 4 and the driving member 5 are connected in transmission. The driving member can be a motor, which drives the active roller 2 to rotate through the reducer 4, thereby driving the screening belt 7 to move.

[0040] In this embodiment, a storage container 6 is provided on one side of the screening belt 7, and the opening at the top of the storage container 6 is lower than the height of the screening belt 7. The storage container 6 can be a mobile trolley with a bucket or a storage box, which can realize the storage of the pepper after screening.

[0041] In this embodiment, baffle plates 8 are provided on both sides of the top of the support frame 1, and the baffle plates 8 are located on both sides of the screening belt 7. The baffle plates 8 are used to prevent the peppercorns from falling from the screening belt 7, thereby ensuring the stability of their transmission.
