DETAILED DESCRIPTION
[0021] The present invention is further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined by the appended claims.
[0022] See also Figure 1 、 Figure 2 、 Figure 3and Figure 4 This is a schematic diagram of the structure of this patent, a pumpkin seed screening device with a guide mechanism, including a cylinder 1 and a storage cylinder 2. The storage cylinder 2 is inserted into the upper wall of the cylinder 1, and a screening mechanism 3 is installed in the inner cavity of the cylinder 1;
[0023] The screening mechanism 3 includes a connecting spring 31, a sieve plate 32, a fixing column 33, a sleeve 34, a lower plate 35 and a push rod 36. One end of the connecting spring 31 is installed on the inner side wall of the cylinder 1, and the other end of the connecting spring 31 is installed on the side wall of the sieve plate 32. The fixing column 33 is installed on the lower wall of the sieve plate 32. The sleeve 34 is installed on the upper wall of the lower plate 35. The sleeve 34 is sleeved on the outer side of the fixing column 33. The push rod 36 is installed on the upper wall of the lower plate 35. The push rod 36 can be inserted into the mesh on the sieve plate 32.
[0024] The pumpkin seeds enter the cylinder 1 through the discharge hole 5 at the bottom of the storage cylinder 2 and fall on the top of the sieve plate 32, so that the pumpkin seeds are screened according to their size through the sieve plate 32. At the same time, the sieve plate 32 vibrates under the action of the vibration motor 12, thereby accelerating the screening efficiency of the pumpkin seeds. At the same time, the lower plate 35 continuously moves up and down during the vibration process, so that the ejector rod 36 is intermittently inserted into the mesh of the sieve plate 32, and the pumpkin seeds stuck in the mesh are ejected to avoid clogging of the sieve plate 32.
[0025] The lower wall of the lower plate 35 is provided with a blanking hole 4;
[0026] The pumpkin seeds that have been screened will pass through the lower plate 35 through the drop hole 4, fall onto the inclined plate 7 below, and then slide out of the cylinder 1 through the first discharge hole 8.
[0027] The lower wall of the storage barrel 2 is provided with a discharge hole 5, and there are four discharge holes 5. The discharge holes 5 are connected to the inner cavity of the storage barrel 2. The lower wall of the inner cavity of the storage barrel 2 is installed with a guide block 6, and the cross section of the guide block 6 is conical;
[0028] The pumpkin seeds in the storage barrel 2 can be guided by the guide block 6 so that they can be evenly discharged through the four discharge holes 5 below the storage barrel 2 and evenly sprinkled onto the screen plate 32, thereby improving the screening efficiency of the device.
[0029] An inclined plate 7 is installed in the inner cavity of the cylinder 1 , and the inclined plate 7 is arranged below the screening mechanism 3 . A first discharge hole 8 is opened on the side wall of the cylinder 1 , and the inclined plate 7 is in contact with the side wall of the first discharge hole 8 .
[0030] A retaining ring 9 is fitted on the upper wall of the sieve plate 32. The retaining ring 9 is made of rubber. A clearance groove 10 is provided on the side wall of the retaining ring 9. A second discharge hole 11 is provided on the side wall of the cylinder 1. The clearance groove 10 can be connected to the second discharge hole 11.
[0031] The outer wall of the retaining ring 9 herein is bonded to the inner wall of the cylinder 1;
[0032] The setting of the retaining ring 9 can prevent the pumpkin seeds from falling directly onto the inclined plate 7 below without being screened by the sieve plate 32, thereby avoiding affecting the screening effect. Because the retaining ring 9 is made of rubber and can be deformed, the vibration of the sieve plate 32 will not cause the retaining ring 9 to separate from the inner wall of the cylinder 1 from the bonded state;
[0033] The larger pumpkin seeds that are screened out can be discharged through the second discharge hole 11. A block is also provided in the second discharge hole 11 to block the second discharge hole 11 during the screening process to prevent unscreened pumpkin seeds from being discharged directly through the second discharge hole 11.
[0034] A vibration motor 12 is installed on the lower wall of the sieve plate 32, and the vibration motor 12 is electrically connected to an external power supply. A ball 13 is installed on the outer side of one end of the fixed column 33 located in the sleeve 34, and the ball 13 can fit with the inner wall of the sleeve 34;
[0035] The provision of the ball 13 can reduce the friction force generated between the fixing column 33 and the sleeve 34, making the sleeve 34 smoother during the sliding process.
[0036] A support leg 14 is installed on the lower wall of the cylinder 1 .
[0037] When the present invention is working, the pumpkin seeds enter the cylinder body 1 through the discharge hole 5 below the storage cylinder 2 and fall on the top of the sieve plate 32, so that the pumpkin seeds are screened according to their size through the sieve plate 32. At the same time, the sieve plate 32 will vibrate under the action of the vibration motor 12, so as to speed up the screening efficiency of the pumpkin seeds. At the same time, the lower plate 35 will continuously move up and down during the vibration process, so that the ejector rod 36 is intermittently inserted into the mesh on the sieve plate 32, and the pumpkin seeds stuck in the mesh are ejected to avoid clogging of the sieve plate 32.
[0038] Smaller pumpkin seeds will pass through the sieve plate 32 and fall onto the inclined plate 7 below, and then be discharged through the first discharge hole 8, while larger pumpkin seeds can be discharged through the second discharge hole 11.
