Description

Technical Field

[0001] The present application relates to the technical field of fruit screening, and in particular to a fruit size screening device. Background Art

[0002] In the Chinese patent with application number 202021199924.6, a fruit size sorting machine is disclosed, which sorts the fruit by size through the screening plates on the left inclined plate and the right inclined plate, thereby avoiding the accumulation of fruit in the box. By replacing the screening plates with different sieve holes, different types of fruits can be screened, thereby improving the applicability of the screening machine.

[0003] With regard to the above-mentioned related technologies, the inventors believe that, in actual use, the above-mentioned device only relies on rolling the fruit on the sieve plate to screen its size. However, when the size of the fruit is similar to the size of the sieve plate, the fruit is easily stuck in the sieve plate, resulting in the inability to continue screening the subsequent fruit. The staff needs to take it out from the sieve plate before they can continue working, which wastes working time and reduces work efficiency.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that when the size of the fruit is similar to the size of the sieve plate, the fruit is easily stuck in the sieve plate, resulting in the inability to continue to screen the subsequent fruits, the present application provides a fruit size screening device.

[0006] The fruit size screening device provided in this application adopts the following technical solution:

[0007] A fruit size screening device comprises a material storage box, the bottom of which is connected to a screening box, four groups of sieve plates with different apertures are arranged in the screening box, a support plate is fixedly installed on the material storage box, a telescopic cylinder is fixedly installed on the bottom of the support plate, a driving mechanism is arranged on the bottom of the telescopic cylinder, and four groups of receiving plates cooperating with the sieve plates are fixedly installed on the screening box.

[0008] Preferably, the driving mechanism comprises four groups of strip holes opened on the screening box, and the screening plate is hinged with connecting rods penetrating the strip holes.

[0009] Preferably, a lifting rod penetrating the connecting rod is fixedly mounted on the bottom of the telescopic cylinder, and a plurality of driving plates cooperating with the connecting rod are fixedly mounted on the lifting rod.

[0010] Preferably, a slide groove is provided on the screening box, a connecting block is fixedly mounted on the screen plate, and a pulley cooperating with the slide groove is fixedly mounted on the connecting block.

[0011] Preferably, four groups of fixing blocks are fixedly mounted on the inner wall of the screening box, a guide rod penetrating the fixing block is fixedly mounted on the connecting block, and the bottom of the connecting block is connected to the fixing block via a spring.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By controlling the telescopic cylinder to reciprocate, the lifting rod is driven to lift and reciprocate, and the lifting rod drives one end of the sieve plate to lift and reciprocate through the connecting rod. At this time, the fruit enters the screening box from the storage box, and the fruit is rolled on the sieve plate by controlling one end of the sieve plate to lift and reciprocate. The fruit is screened by setting sieve plates with different apertures. When the fruit rolls to the end of the sieve plate, pressure is applied to the end of the sieve plate, thereby compressing the spring. When the fruit leaves the sieve plate, the spring extends, and the compression and extension of the spring are controlled to drive the end of the sieve plate to shake. By shaking the end and starting end of the sieve plate, the fruit can be effectively prevented from being stuck in the aperture of the sieve plate, thereby improving work efficiency.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a fruit size screening device. Figure 1-4A fruit size screening device comprises a storage box 1, a screening box 2 is connected and installed at the bottom of the storage box 1, four groups of sieve plates 3 with different apertures are arranged in the screening box 2, a support plate 4 is fixedly installed on the storage box 1, a telescopic cylinder 5 is fixedly installed at the bottom of the support plate 4, a driving mechanism is arranged at the bottom of the telescopic cylinder 5, four groups of receiving plates 6 cooperating with the sieve plates 3 are fixedly installed on the screening box 2, the driving mechanism comprises four groups of strip holes 7 opened on the screening box 2, connecting rods 8 penetrating the strip holes 7 are hinged on the sieve plates 3, a lifting rod 9 penetrating the connecting rod 8 is fixedly installed at the bottom of the telescopic cylinder 5, and a plurality of driving plates 10 cooperating with the connecting rod 8 are fixedly installed on the lifting rod 9;

[0021] By adopting the above technical solution, the telescopic cylinder 5 is controlled to reciprocate and retract, thereby driving the lifting rod 9 to reciprocate and lift. The lifting rod 9 cooperates with the driving plate 10 to drive the connecting rod 8 to reciprocate and lift, thereby driving the starting end of the screen plate 3 to reciprocate and lift, thereby shaking the fruit at the starting end.

[0022] Reference Figure 3-4 A chute 11 is provided on the screening box 2, a connecting block 12 is fixedly installed on the screen plate 3, a pulley 13 matching the chute 11 is fixedly installed on the connecting block 12, four groups of fixing blocks 14 are fixedly installed on the inner wall of the screening box 2, a guide rod 15 penetrating the fixing block 14 is fixedly installed on the connecting block 12, and the bottom of the connecting block 12 is connected to the fixing block 14 through a spring 16;

[0023] By adopting the above technical solution, when the fruit rolls to the end of the sieve plate 3, pressure will be applied to the end of the sieve plate 3, thereby compressing the spring 16. When the fruit leaves the sieve plate 3, the spring 16 extends, and the compression and extension of the spring 16 are controlled to drive the end of the sieve plate 3 to shake. By shaking the end and the starting end of the sieve plate 3, the fruit can be effectively prevented from being stuck in the aperture of the sieve plate 3. Through the action of the slide groove 11 and the pulley 13, the friction between the connecting block 12 and the screening box 2 can be reduced to prevent the friction from being greater than the elastic force of the spring 16, resulting in the end of the sieve plate 3 being unable to shake.

[0024] The implementation principle of a fruit size screening device in an embodiment of the present application is as follows: controlling the telescopic cylinder 5 to reciprocate and retract, thereby driving the lifting rod 9 to reciprocate and lift, and the lifting rod 9 drives one end of the sieve plate 3 to reciprocate and lift through the connecting rod 8. At this time, the fruit enters the screening box 2 from the storage box 1, and the fruit is rolled on the sieve plate 3 by controlling one end of the sieve plate 3 to reciprocate and lift. The fruit is screened by providing sieve plates 3 with different aperture sizes. When the fruit rolls to the end of the sieve plate 3, pressure is applied to the end of the sieve plate 3, thereby compressing the spring 16. When the fruit leaves the sieve plate 3, the spring 16 extends, and the compression and extension of the spring 16 are controlled to drive the end of the sieve plate 3 to shake. By shaking the end and starting end of the sieve plate 3, the fruit can be effectively prevented from being stuck in the aperture of the sieve plate 3, thereby improving work efficiency.
