A drum screening device for grading the size of Chinese yam tubers.

Abstract

This utility model discloses a drum screening device for grading the size of Chinese yam tubers, relating to the field of Chinese yam tuber screening technology. It includes a base, a first screening cylinder, a second screening cylinder, and a third screening cylinder, with a feeding mechanism on the top of the base. This utility model, through the feeding mechanism, can separately feed tubers of different sizes. During use, by activating the electric cylinder and through the cooperation of threaded holes and bolts, the first, second, and third screening cylinders are adjusted to angles conducive to feeding. By opening the corresponding door panels, tubers of the corresponding sizes are fed separately.

This ensures the feeding efficiency and effect of the device.

Description

Technical Field

[0001] This utility model relates to the field of Chinese yam tuber screening technology, specifically a drum screening device for grading the size of Chinese yam tubers. Background Technology

[0002] Chinese yam tubers vary in size, and grading can separate them into different grades according to size, making the product more in line with market demand and consumer preferences, which helps to improve product quality and market competitiveness. In the process of grading and screening Chinese yam, a drum screening device for grading the size of Chinese yam tubers is required.

[0003] Most of the currently used drum screening devices have difficulty discharging the graded and screened Chinese yam tubers. In the process of use, the traditional method of discharging is to directly open the door and then the staff discharging the Chinese yam tubers. This method is not only slow, but also easy to mix tubers of different sizes, which may result in the need to re-screen them, making the discharging efficiency and discharging effect of the screening device poor. Utility Model Content

[0004] The purpose of this invention is to provide a drum screening device for grading the size of Chinese yam tubers, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drum screening device for grading the size of Chinese yam tubers, comprising a base, a first screening cylinder, a second screening cylinder, and a third screening cylinder. A feeding mechanism is provided on the top of the base, and the feeding mechanism includes a first support plate. The first support plate is provided on the top of the base, and a first rotating shaft is connected to the inner wall of the first support plate through a bearing. Turntables are provided at both ends of the first rotating shaft.

[0006] As a preferred technical solution, threaded holes are provided inside the turntable and inside the first support plate, bolts are provided on the inner wall of the threaded holes, and a first rotating block is provided on the outer wall of the first rotating shaft.

[0007] As a preferred technical solution, a second support plate is provided on the top of the base, and a second rotating shaft is provided on the inner side of the second support plate.

[0008] As a preferred technical solution, a second rotating block is provided on the outer wall of the second rotating shaft, an electric cylinder is provided on the top of the second rotating block, and a third rotating block is provided on the top of the electric cylinder.

[0009] As a preferred technical solution, the inner wall of the third rotating block is provided with a third rotating shaft, and both ends of the third rotating shaft are provided with connecting plates. The top of the connecting plate is fixedly connected to the outer wall of the first screening cylinder. One end of the first screening cylinder is provided with a door panel, and one side of the door panel is provided with a handle.

[0010] As a preferred technical solution, a fixing plate is provided on the top of the first rotating block, and a first screening cylinder is provided on one side of the fixing plate. Holes are provided inside the first screening cylinder, the second screening cylinder, and the third screening cylinder.

[0011] As a preferred technical solution, a rotating screening mechanism is provided on the other side of the fixed plate. The rotating screening mechanism includes a tray, and a motor is provided on the top of the tray.

[0012] As a preferred technical solution, the output shaft of the motor is connected to a motor shaft via a coupling, the outer wall of the motor shaft is connected through to the other side of the fixing plate, a fixing plate is provided at one end of the motor shaft, a second screening cylinder is provided on one side of the fixing plate, and a third screening cylinder is provided on one side of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of the feeding mechanism, can achieve the function of feeding tubers of different sizes separately. During use, by activating the electric cylinder and cooperating with the threaded hole and bolt, the first screening cylinder, the second screening cylinder and the third screening cylinder are adjusted to an angle that is easy to feed. By opening the corresponding door plate, the tubers of the corresponding size are fed separately. This avoids the traditional feeding method, which directly opens the door plate and then the worker feeds the Chinese yam tubers, resulting in a slow feeding speed and easy mixing of tubers of different sizes, which may require re-screening. This ensures the feeding efficiency and feeding effect of the device.

[0014] 2. This utility model, through the setting of a rotary screening mechanism, can achieve the function of rotating the tubers and screening them in stages. During use, the second and third screening cylinders are rotated by starting the motor to screen the tubers in stages. This avoids the situation where the tubers cannot move fully in the cylinder due to the difficulty in rotating the second and third screening cylinders, which would slow down the screening speed and may result in incomplete screening of the tubers. This ensures the screening efficiency and screening effect of the device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, this utility model provides the following technical solution, including a base 1, a first screening cylinder 5, a second screening cylinder 6 and a third screening cylinder 7. A feeding mechanism 2 is provided on the top of the base 1. A fixing plate 4 is provided on the top of the first rotating block 206. The first screening cylinder 5 is provided on one side of the fixing plate 4. Holes 8 are provided inside the first screening cylinder 5, the second screening cylinder 6 and the third screening cylinder 7. A rotating screening mechanism 3 is provided on the other side of the fixing plate 4. The second screening cylinder 6 is provided on one side of the fixing plate 304 and the third screening cylinder 7 is provided on one side of the fixing plate 304.

[0019] When this screening device is needed to grade and screen yam tubers of different sizes, firstly, open the door plate 214 through handle 215, and put all the yam tubers into the third screening cylinder 7. Then close the door plate 214, and the screening work can begin. At this time, the third screening cylinder 7 and the second screening cylinder 6 need to be rotated to grade and screen the yam tubers. The grading and screening of the yam tubers is carried out by the set rotating screening mechanism 3. Since the aperture of the third screening cylinder 7 is larger than that of the second screening cylinder 6 and the first screening cylinder 5, the largest yam tubers are placed in the third screening cylinder 7, the medium-sized tubers are placed in the second screening cylinder 6, and the smaller yam tubers are placed in the first screening cylinder 5. The holes 8 on the screen cylinder are all square holes. Since most yams are cylindrical, the square holes provide a greater angle for material to escape when passing through, making it less likely to get stuck, thus completing the grading and screening work. After grading and screening, the yam tubers need to be unloaded by the set unloading mechanism 2, thus completing the work.

[0020] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a feeding mechanism 2 is provided on the top of the base 1. The feeding mechanism 2 includes a first support plate 201. The inner wall of the first support plate 201 is connected to a first rotating shaft 202 via bearings. Turntables 203 are provided at both ends of the first rotating shaft 202. Threaded holes 204 are provided inside both the turntables 203 and the first support plate 201. Bolts 205 are provided on the inner wall of the threaded holes 204. A first rotating block 206 is provided on the outer wall of the first rotating shaft 202. A second support plate 20 is provided on the top of the base 1. 7. A second rotating shaft 208 is provided on the inner side of the second support plate 207. A second rotating block 209 is provided on the outer wall of the second rotating shaft 208. An electric cylinder 210 is provided on the top of the second rotating block 209. A third rotating block 211 is provided on the top of the electric cylinder 210. A third rotating shaft 212 is provided on the inner wall of the third rotating block 211. A connecting plate 213 is provided at both ends of the third rotating shaft 212. The top of the connecting plate 213 is fixedly connected to the outer wall of the first screening cylinder 5. A door panel 214 is provided at one end of the first screening cylinder 5. A handle 215 is provided on one side of the door panel 214.

[0021] After grading and screening, the Chinese yam tubers need to be fed into the machine. At this point, bolt 205 is rotated out of the threaded hole 204, disengaging it from the control of the turntable 203. Then, electric cylinder 210 is activated, causing it to shorten. Through the rotation of the third rotating block 211 on the outer wall of the third rotating shaft 212, the rotation of the second rotating block 209 on the outer wall of the second rotating shaft 208, and the rotation of the first rotating shaft 202 within the first support plate 201, the fixed plate 4 begins to rotate. The fixed plate 4 then rotates the first screening cylinder 5, the second... The screening cylinder 6 and the third screening cylinder 7 are rotated to a suitable angle so that the side with the door panel 214 faces down. Then, the bolt 205 is rotated and inserted into the threaded hole 204 in the turntable 203 and the threaded hole 204 in the first support plate 201 to fix the angle. Then, the smallest door is opened first, and the largest tuber is fed through its tilt angle. After feeding, the medium-sized door is opened to feed the medium-sized tuber. After feeding, the largest door panel 214 is opened through the handle 215 to feed the smallest tuber, thus completing the feeding work.

[0022] like Figure 1 , Figure 2 and Figure 6 As shown, a rotary screening mechanism 3 is provided on the other side of the fixed plate 4. The rotary screening mechanism 3 includes a support plate 301. A motor 302 is provided on the top of the support plate 301. The output shaft of the motor 302 is connected to a motor shaft 303 through a coupling. The outer wall of the motor shaft 303 is connected through the other side of the fixed plate 4. A fixed disk 304 is provided at one end of the motor shaft 303. A second screening cylinder 6 is provided on one side of the fixed disk 304. A third screening cylinder 7 is provided on one side of the fixed disk 304.

[0023] Specifically, when the screening device is needed to grade and screen yam tubers of different sizes, first, open the door panel 214 by handle 215, put the yam tubers into the third screening cylinder 7, and then close the door panel 214. At this time, the screening work can be carried out. The third screening cylinder 7 and the second screening cylinder 6 need to be rotated to grade and screen the yam tubers. At this time, the motor 302 is started, so that the motor 302 drives the motor shaft 303 to start rotating. The motor shaft 303 drives the fixed plate 304 to start rotating. The fixed plate 304 drives the second screening cylinder 6 and the third screening cylinder 7 to start rotating, so that the yam tubers in the third screening cylinder 7 are graded and screened through the second screening cylinder 6 and the third screening cylinder 7, thereby completing the rotational screening work.

[0024] The working principle of this utility model is as follows: When the screening device is needed to grade and screen yam tubers of different sizes, firstly, open the door panel 214 through handle 215, place the yam tubers into the third screening cylinder 7, and then close the door panel 214. At this time, the screening work can be carried out. It is necessary to rotate the third screening cylinder 7 and the second screening cylinder 6 to grade and screen the yam tubers. At this time, the motor 302 is started, causing the motor shaft 303 to start rotating. The motor shaft 303 drives the fixed plate 304 to start rotating, and the fixed plate 304 drives the second screening cylinder 6 and the third screening cylinder 7 to start rotating. The third screening cylinder 7 begins to rotate, causing the yam tubers inside it to pass through the second screening cylinder 6 and the third screening cylinder 7 for grading and screening, thus completing the rotary screening process. Since the aperture of the third screening cylinder 7 is larger than that of the second screening cylinder 6, which is larger than that of the first screening cylinder 5, the rotation ensures that the largest yam tubers are in the third screening cylinder 7, medium-sized tubers are in the second screening cylinder 6, and smaller yam tubers are in the first screening cylinder 5. The holes 8 on the screening cylinders are all square holes. Since most yams are cylindrical, the square holes provide a greater angle for material to escape, making it less likely for the material to get stuck. After the grading and screening are completed, the yam tubers need to be fed into the machine. At this point, bolt 205 is rotated out of the threaded hole 204, disengaging it from the control of the turntable 203. Then, the electric cylinder 210 is activated, causing it to shorten. The electric cylinder 210, through the rotation of the third rotating block 211 on the outer wall of the third rotating shaft 212, the rotation of the second rotating block 209 on the outer wall of the second rotating shaft 208, and the rotation of the first rotating shaft 202 within the first support plate 201, drives the fixed plate 4 to rotate. The fixed plate 4 then drives the first screening cylinder 5. The second screening cylinder 6 and the third screening cylinder 7 are rotated to a suitable angle so that the side with the door panel 214 faces down. Then, the bolt 205 is rotated and inserted into the threaded hole 204 in the turntable 203 and the threaded hole 204 in the first support plate 201 to fix the angle. Then, the smallest door is opened first, and the largest tuber is fed through its tilt angle. After feeding, the medium-sized door is opened to feed the medium-sized tuber. After feeding, the largest door panel 214 is opened through the handle 215 to feed the smallest tuber, thus completing the feeding work.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
