[0028] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0029] The present invention provides a wild jujube screening and packaging device, as Figure 1 and Figure 2 shown, including a chassis 5 for carrying a screening barrel 1, a feeding mechanism 2, a guiding mechanism 3 and an aggregate mechanism 4. The screening barrel 1 is rotatably arranged on the chassis 5. The feeding mechanism 2 is arranged at the feeding end of the screening barrel 1 and is connected to the chassis 5. The screening barrel 1 includes a cleaning barrel 6 and a waste barrel 7, and a first screening barrel 8 and a second screening barrel 9 arranged between the cleaning barrel 6 and the waste barrel 7. The cleaning barrel 6, the first screening barrel 8, the second screening barrel 9 and the waste barrel 7 are respectively provided with water filtering holes 10, first screening holes 11, second screening holes 12 and coarse screening holes 13. The guiding mechanism 3 includes a first collection chamber 14, a second collection chamber 15, a third collection chamber 16, a fourth collection chamber 17 respectively communicating with the water filtering holes 10, the first screening holes 11, the second screening holes 12 and the coarse screening holes 13, and a drain port 18, a first discharge port 19, a second discharge port 20 and a discharge port 21 respectively communicating with the first collection chamber 14, the second collection chamber 15, the third collection chamber 16 and the fourth collection chamber 17. The aggregate mechanism 4 includes a movable frame 22 slidably arranged on the chassis 5. A collection barrel 23 cooperating with the first discharge port 19 and the second discharge port 20 is arranged on the movable frame 22. When the wild jujubes enter the cleaning barrel 6, the wild jujubes in the cleaning barrel 6 are sprayed and cleaned by a spray gun 24. Cooperating with the rotation of the screening barrel 1 on the chassis 5, the wild jujubes in the cleaning barrel 6 are driven to continuously roll, so that the spray gun 24 can fully spray and wash the surface of the wild jujubes, avoiding that some areas of the wild jujubes are located on the lower side and cannot be cleaned, thereby improving the cleaning effect of the wild jujubes and the quality after the production of the wild jujubes. At the same time, the sewage after cleaning passes through the water filtering holes 10, is collected in the first collection chamber

[0030] Preferably, as Figure 1 , Figure 3 and Figure 4 shown, the feeding mechanism 2 includes a material guiding plate 25 arranged at the top of the cleaning cylinder 6. A spiral plate 26 is rotatably connected to the material guiding plate 25. By rotating the spiral plate 26 on the material guiding plate 25, the wild jujubes are gradually pushed to move on the material guiding plate 25, avoiding the blockage of the wild jujubes on the material guiding plate 25 and affecting the subsequent normal feeding, thereby improving the efficiency of screening wild jujubes; it also includes a roller 27 rotatably arranged on the chassis 5. The material guiding plate 25 is arranged at the top of the chassis 5. A plurality of material pushing mechanisms 28 are arranged on the roller 27. A number of feeding ports 29 that cooperate with the material pushing mechanisms 28 and the material guiding plate 25 are arranged on the roller 27. It further includes a conveying mechanism 30 arranged on the chassis 5 and cooperating with the material pushing mechanisms 28. The conveying mechanism 30 is connected to the previous process. By the rotation of the roller 27 on the chassis 5, the material pushing mechanisms 28 are driven to move together with the roller 27. When it moves to the left side, the picked wild jujubes are continuously supplied to the corresponding material pushing mechanisms 28 through the conveying mechanism 30. Then, it continuously drives the material pushing mechanisms 28 to move until it moves to the topmost position. The material pushing mechanisms 28 can no longer intercept the vertical movement of the wild jujubes, and under the action of their own gravity, they fall into the guiding groove at the top. By the rotation of the spiral plate 26 on the chassis 5, the spiral plate 26 contacts the wild jujubes, realizing the feeding of the wild jujubes. And the whole process is driven by mechanical transmission, without the need for manual continuous feeding of the picked wild jujubes into the material guiding plate 25, thereby improving the efficiency of screening wild jujubes and reducing the labor intensity of workers.

[0031] Preferably, as Figure 3 and Figure 4As shown, the material feeding mechanism 28 includes vertical plates 31 symmetrically arranged on the roller 27. Between the two vertical plates 31, a fixed roller 32 and a movable roller 33 are provided. A fine sieve hole 34 is formed between the fixed roller 32 and the movable roller 33. The conveying mechanism 30 includes a conveyor belt 35 and rollers 36 rotatably arranged on the chassis 5. A number of inclined plates 37 cooperating with the fine sieve hole 34 are provided on the side of the roller 36. When the inclined plate 37 moves to one side of the conveyor belt 35, its angle is inclined upward. When the inclined plate 37 moves above the fine sieve hole 34, its angle is inclined downward. A recycling box 38 cooperating with the fine sieve hole 34 is provided on the chassis 5; the picked wild jujubes are driven by the conveyor belt 35 to realize continuous conveying of the picked wild jujubes. When the picked wild jujubes move to the end of the conveyor belt 35, they fall onto the inclined plate 37 on one side of the conveyor belt 35. Since the angle of the inclined plate 37 is inclined upward at this time, it prevents the wild jujubes from falling off the roller 36. Then, the roller 36 is further rotated until the inclined plate 37 drives the wild jujubes to move above the fine sieve hole 34. At this time, since the angle of the inclined plate 37 is inclined downward, the wild jujubes on the inclined plate 37 fall above the fine sieve hole 34, and the leaves or other smaller impurities mixed with the wild jujubes, as well as the smaller wild jujubes, will pass through the fine sieve hole 34 formed between the fixed roller 32 and the movable roller 33 and fall into the recycling box 38 provided on the chassis 5, thereby realizing the preliminary screening of the wild jujubes, removing impurities such as leaves and soil on the wild jujubes, reducing the burden of subsequent cleaning and screening, and further improving the efficiency of screening wild jujubes.

[0032] Preferably, as Figure 3 , Figure 4 and Figure 5 shown, the fixed roller 32 is rotatably connected to the vertical plate 31. A vertical groove 39 for slidably connecting with the movable roller 33 is provided on the vertical plate 31. Turntables 40 are rotatably connected to both sides of the roller 27. A number of inclined grooves 41 for slidably connecting with the movable roller 33 are provided on the turntable 40. By rotating the turntable 40 on the roller 27, the inclined grooves 41 provided on the turntable 40 further come into contact with the movable roller 33. At the same time, through the slidable connection between the vertical groove 39 and the movable roller 33, it plays a guiding role in the sliding of the movable roller 33 on the vertical plate 31, thereby driving the movable roller 33 to move between the two vertical plates 31 in a specified direction, thereby adjusting the size of the fine sieve hole 34, changing the size of the initially screened wild jujubes, putting the smaller wild jujubes into the recycling box 38, and further improving the quality of the screened wild jujubes.

[0033] Preferably, as Figure 4 and Figure 5As shown, a plurality of first columns 42 are provided between the two turntables 40, and a first rotating shaft 43 is rotatably connected to the roller 27. Both ends of the first rotating shaft 43 are respectively provided with a shift block 44, and the shift block 44 contacts one of the first columns 42 and drives it to move to the position where the previous first column 42 was located. The two sides of the roller 27 are slidably connected to the limit block 45, and a protrusion 46 is provided on one side of the limit block 45. The two sides of the protrusion 46 contact two adjacent first columns 42 respectively. A first spring 47 is provided between the limit block 45 and the roller 27. Specifically, a guide rod is provided on the roller 27, and the first spring 47 is sleeved on the outer side of the guide rod to guide the compression of the first spring 47; a connecting rod 48 is provided on one side of the shift block 44, and the end of the connecting rod 48 is provided with a second column 49 that contacts the limit block 45; a first motor 50 is rotatably connected to the base frame 5, and a driving gear 51 is provided on the movable end of the first motor 50. The first rotating shaft 43 is provided with a driven gear 52 meshing with the driving gear 51. The first motor 50 drives the driving gear 51 to rotate, and transmits torque through the driven gear 52, driving the first rotating shaft 43 to rotate on the base frame 5, thereby driving the shift blocks 44 provided at both ends of the first rotating shaft 43 to move together, and at the same time driving the connecting rod 48 provided on the other side of the shift block 44 to rotate, and the second column 49 on the connecting rod 48 first contacts the limit block 45, driving the limit block 45 to move on the roller 27 until the protrusion 46 provided on one side of the limit block 45 slides out from between the adjacent first columns 42, thereby releasing the restriction on the rotation of the turntable 40 on the roller 27, and then contacts one of the first columns 42 through the shift block 44, driving it to move to the position before the adjacent first column 42, thereby driving the turntable 40 to rotate on the roller 27, adjusting the size of the fine sieve holes 34, changing the size of the initially screened sour dates, and putting the smaller sour dates into the recycling box 38, thereby improving the quality of the sour dates after screening.

[0034] Preferably, Figure 4 and Figure 6As shown in the figure, several driving rollers 53 are rotatably connected to the chassis 5, and the conveyor belt 35 is sleeved on the outside of the driving rollers 53. A first driven wheel 54 is provided on one of the driving rollers 53, and a second driven wheel 55 is provided on one side of the roller 36. It also includes a second motor 56 provided on the chassis 5 and a driving wheel 57 provided on the movable end of the second motor 56. A lever 58 and an arc-shaped block 59 are respectively provided on both sides of the driving wheel 57. A third column 60 and a fourth column 61 are respectively provided on the first driven wheel 54 and the second driven wheel 55. The lever 58 contacts the third column 60 and the fourth column 61 in sequence, driving the first driven wheel 54 and the second driven wheel 55 to rotate on the chassis 5 in sequence. The arc-shaped block 59 contacts multiple third columns 60 and fourth columns 61 simultaneously, restricting the rotation of the first driven wheel 54 and the second driven wheel 55 on the chassis 5 in sequence. By driving the driving wheel 57 to rotate through the second motor 56, the arc-shaped block 59 provided on one side of the driving wheel 57 slides out between several third columns 60, releasing the restriction on the rotation of the first driven wheel 54 on the chassis 5. At the same time, by contacting the fourth column 61 on one of the second driven wheels 55 through the lever 58, the generated component force drives the second driven wheel 55 to rotate on the chassis 5. After further rotating the driving wheel 57, the arc-shaped block 59 will contact multiple fourth columns 61, restricting the rotation of the second driven wheel 55 on the chassis 5, avoiding the second driven wheel 55 being accidentally driven to rotate by an external force, causing the roller 36 to rotate on the chassis 5, resulting in the premature dropping of the wild jujubes on the inclined plate 37 and affecting the normal feeding of the subsequent wild jujubes, thereby ensuring the stability of the overall structure and improving the efficiency of screening wild jujubes. At the same time, by contacting one of the third columns 60 on the first driven wheel 54 through the lever 58, the generated component force drives the first driven wheel 54 to rotate on the chassis 5. Repeating the above steps multiple times will alternately drive the roller 36 and the conveyor belt 35 to rotate. When the driving wheel 57 drives the conveyor belt 35 to rotate and drives the wild jujubes to move forward and fall onto the roller 36, the rotation of the roller 36 is restricted by the arc-shaped block 59, avoiding the wild jujubes from falling due to contact with the rotating roller 36 or not falling on the predetermined inclined plate 37, thereby improving the feeding efficiency of the wild jujubes. At the same time, when the driving wheel 57 drives the roller 36 to rotate and conveys the wild jujubes to the feeding mechanism 28, the movement of the conveyor belt 35 is restricted by the arc-shaped block 59, avoiding the wild jujubes from falling due to not falling on the predetermined inclined plate 37, further improving the feeding efficiency of the wild jujubes.

[0035] Preferably, as Figure 3 and Figure 4As shown in the figure, a plurality of first positioning rollers 62 in contact with the drum 27 are provided on the chassis 5, which play a role in limiting the rotation of the drum 27 on the chassis 5, and at the same time reduce the friction between the drum 27 and the chassis 5, facilitating the rotation of the drum 27 on the chassis 5; the aggregate mechanism 4 is arranged at the bottom of the sieve barrel 1 and is connected to the chassis 5, the material guiding mechanism 3 is arranged between the sieve barrel 1 and the aggregate mechanism 4 and is connected to the chassis 5, and a plurality of second positioning rollers 63 in contact with the turntable 40 are provided on the drum 27, which play a role in limiting the rotation of the turntable 40 on the drum 27, and at the same time reduce the friction between the turntable 40 and the drum 27, facilitating the rotation of the turntable 40 on the drum 27. A screw rod 64 is rotatably connected to the chassis 5, and the screw rod 64 is threadedly connected to the movable frame 22. Specifically, the screw rod 64 is connected to a stepping motor to control the movement of the movable frame 22 on the chassis 5.

[0036] Preferably, as Figure 3 shown in the figure, it further includes a third motor 65 arranged on the chassis 5, a second rotating shaft 66 and a third rotating shaft 67 rotatably arranged on the chassis 5.

A rack 75 that meshes with the fifth gear 73 is provided on one side of the drum 27. By driving the third rotating shaft 67 to rotate on the chassis 5 through the third motor 65, the first gear 68 and the second gear 69 are driven to rotate on the chassis 5 together. Since the third gear 70 is provided at the end of the second rotating shaft 66 and the fourth gear 71 that meshes with both the first gear 68 and the third gear 70 is rotatably connected to the chassis 5, the second rotating shaft 66 is driven to rotate on the chassis 5. Since the second rotating shaft 66 is connected to the sieve barrel 1, the sieve barrel 1 is driven to rotate on the chassis 5, realizing the cleaning and screening of wild jujubes; at the same time, since the sixth gear 74 provided at the end of the fourth rotating shaft 72 meshes with the second gear 69, the spiral plate 26 connected to the fourth rotating shaft 72 is driven to rotate on the chassis 5, and the spiral plate 26 contacts the wild jujubes, realizing the continuous feeding of wild jujubes; in addition, since the fifth gear 73 arranged on the chassis 5 meshes with the rack 75 provided on the drum 27, the drum 27 will be driven to rotate on the chassis 5. Thus, through the third motor 65, the sieve barrel 1, the spiral plate 26 and the drum 27 are simultaneously driven to rotate on the chassis 5, eliminating the need to separately set up a power device, further reducing the cost required for the installation of the power device and the space required for manufacturing. In addition, by adjusting the tooth number ratio among the first gear 68, the third gear 70 and the fourth gear 71, the transmission ratio between the second rotating shaft 66 and the third rotating shaft 67 is changed, and further the speed ratio of the rotation of the screening barrel 1 and the spiral plate 26 is adjusted, so as to adjust the balance between feeding and screening and cleaning, ensure the screening and cleaning efficiency, and improve the quality of wild jujubes after screening and cleaning. In addition, by fixing the speed ratio of the roller 27 and the spiral plate 26, it is ensured that the feeding of the roller 27 and the feeding of the spiral plate 26 are in a balanced state, avoiding the accumulation of materials in the material guiding plate 25, increasing the working burden of driving the spiral plate 26 to rotate, or there is no material supply to the material guiding plate 25 for a long time, reducing the feeding efficiency of wild jujubes, and thus improving the screening and cleaning efficiency of wild jujubes.

[0037] Preferably, as Figure 7 and Figure 8 shown, the aggregate mechanism 4 further includes a first valve 76 and a second valve 77 symmetrically arranged on the first discharge port 19, and a third valve 78 and a fourth valve 79 arranged on the second discharge port 20. The first valve 76, the second valve 77, the third valve 78 and the fourth valve 79 each include a valve plate 80 symmetrically and rotatably arranged on the first discharge port 19 or the second discharge port 20. A fifth rotating shaft 81 rotatably connected to the first discharge port 19 or the second discharge port 20 is provided on the valve plate 80. One end of the fifth rotating shaft 81 extends to the outside and is provided with a seventh gear 82. The adjacent seventh gears 82 are meshed with each other, so as to connect a plurality of flap plates on the first valve 76 and the second valve 77 together, and connect a plurality of flap plates on the third valve 78 and the fourth valve 79 together. When one of the valve plates 80 is driven to rotate, the remaining valve plates 80 of the first valve 76 and the second valve 77 are driven to rotate, or the flap plates of the third valve 78 and the fourth valve 79 are driven to rotate.

[0038] Preferably, as Figures 7 - 11As shown in the figure, a first slider 83 and a second slider 84 are slidably connected to the chassis 5. The end portions of the first slider 83 and the second slider 84 are respectively provided with a first inclined surface 85 and a second inclined surface 86 that are in contact with the first valve 76 and the second valve 77. A third slider 87 is slidably connected to the chassis 5. A first wedge block 88 and a second wedge block 89 are provided on the third slider 87. A wedge-shaped groove 90 is provided at the end of the first slider 83. The two sides of the first wedge block 88 are respectively provided with a third inclined surface 91 and a fourth inclined surface 92 that are in contact with the wedge-shaped groove 90. One side of the second wedge block 89 is provided with a fifth inclined surface 93 that is in contact with the second slider 84. The end of the second slider 84 is in contact with the end of the second wedge block 89. A first tension spring 94 and a second tension spring 95 are respectively provided between the first slider 83 and the second slider 84 and the chassis 5. A telescopic cylinder 96 is provided on the chassis 5. The movable end of the telescopic cylinder 96 is connected to the third slider 87. When it is necessary to close the first discharge port 19 and the second discharge port 20 simultaneously, the telescopic cylinder 96 drives the third slider 87 to slide on the chassis 5, so that the first inclined surface 85 provided on the first wedge block 88 is in contact with one side of the wedge-shaped groove 90, and the generated component force drives the first slider 83 to slide on the chassis 5 until the first inclined surface 85 provided at its end is in contact with one of the valve plates 80 of the first valve 76, driving the valve plate 80 to rotate on the first discharge port 19, and transmitting torque through the fifth rotating shaft 81 to drive one of the seventh gears 82 to rotate. Since two adjacent seventh gears 82 are meshed with each other, the remaining adjacent valve plates 80 are simultaneously driven to rotate in the opposite direction, so that the two valve plates 80 on the first valve 76 are simultaneously closed, avoiding the subsequent continued dropping of wild jujubes in the first discharge port 19, and at the same time opening the two valve plates 80 on the second valve 77, so that the wild jujubes fall from the first collection chamber 14 into the first discharge port 19; in addition, at this time, the end of the second slider 84 is in contact with the end surface of the second wedge block 89, so that the first slider 83 continuously contacts the valve plate 80 of the third valve 78, thereby simultaneously closing the first discharge port 19 and the second discharge port 20, avoiding the dropping of wild jujubes from the first discharge port 19 or the second discharge port 20 during the process of the movable frame 22 driving the collection bucket 23 to move, and thus reducing the loss of qualified wild jujubes during the screening process; When it is necessary to close the first discharge port 19 and open the second discharge port 20, the telescopic cylinder 96 drives the third slider 87 to slide reversely on the chassis 5, so that the fourth inclined surface 92 provided on one side of the first wedge block 88 contacts the other side of the wedge groove 90, continuously keeping the first valve 76 closed and the second valve 77 open; in addition, the third slider 87 drives the second wedge block 89 to move at the same time, so that the second slider 84 no longer contacts the second wedge block 89, and further moves the second wedge block 89 until the fifth inclined surface 93 provided on one side of the second wedge block 89 no longer contacts the second slider 84, and under the resilience of the second tension spring 95, the second slide plate is reset, releasing the restriction on the opening of the third valve 78. Under the action of the self-weight of the wild jujubes in the second bin, the valve plate 80 of the third valve 78 is pushed to rotate in the second bin. Similarly, through the cooperation of the fifth rotating shaft 81 and the seventh gear 82, the valve plate 80 of the fourth valve 79 is driven to close, intercepting the subsequent wild jujubes from entering the second discharge port 20 from the third collection cavity 16, thereby slowing down the height of the continuous fall of the wild jujubes and reducing the damage caused during the fall of the wild jujubes, and improving the quality of the screened wild jujubes; Repeat the above steps multiple times to simultaneously realize the switching of the opening and closing of the first discharge port 19 and the second discharge port 20, and there is no need to separately set a power device to control the opening and closing of the first valve 76, the second valve 77, the third valve 78 and the fourth valve 79, thereby reducing the space required for the installation of the power device and the cost required for manufacturing, and at the same time reducing the programming difficulty of controlling the opening and closing of the first valve 76, the second valve 77, the third valve 78 and the fourth valve 79.

[0039] Embodiment 1 The present invention provides a wild jujube screening and packaging device, as Figure 1 and Figure 2 shown, by rotating the spiral plate 26 on the guide plate 25, gradually pushing the wild jujubes to move on the guide plate 25, avoiding the blockage of the guide plate 25 by the wild jujubes and affecting the subsequent normal feeding, thereby improving the efficiency of screening wild jujubes; After the wild jujubes enter the cleaning cylinder 6, the wild jujubes in the cleaning cylinder 6 are sprayed by the spray gun 24. In cooperation with the rotation of the sieve barrel 1 on the chassis 5, the wild jujubes in the cleaning cylinder 6 are continuously tumbled, so that the spray gun 24 can fully spray the surface of the wild jujubes, avoiding that some areas of the wild jujubes are located at the lower side and cannot be cleaned, thereby improving the cleaning effect of the wild jujubes and the quality of the wild jujubes after production. At the same time, the sewage after cleaning passes through the water filtering holes 10 and is collected in the first collection chamber 14 provided in the aggregate mechanism 4, and is discharged to the outside through the drain port 18. Then the wild jujubes pass through the first screening cylinder 8 and the second screening cylinder 9 in sequence. The wild jujubes that meet the size requirements pass through the first sieve holes 11 and the second sieve holes 12 provided in the first screening cylinder 8 and the second screening cylinder 9 respectively, and are collected in the second collection chamber 15 or the third collection chamber 16 provided in the aggregate mechanism 4, so as to realize the screening of the wild jujubes. At the same time, the screening and cleaning mechanisms are both arranged on the sieve barrel 1, and the screening and cleaning operations can be carried out in sequence without separately cleaning and screening the wild jujubes, thereby reducing the transportation steps required in the intermediate process and improving the production efficiency of the wild jujubes. At the same time, by the rotation of the sieve barrel 1 on the chassis 5, it is prevented that the wild jujubes stay in one place for a long time and block the first sieve holes 11 or the second sieve holes 12, thereby improving the screening efficiency of the wild jujubes. When the quantity reaches a certain amount, the movable seat slides on the chassis 5, driving the collection barrel 23 to slide on the chassis 5, and respectively sliding to the lower sides of the first discharge port 19 or the second discharge port 20, moving the screened wild jujubes to the next process. In addition, several groups of screening cylinders can be set according to actual needs, and in cooperation with sieve holes of different sizes, the multi-stage screening of the wild jujubes can be further realized, and the screening effect of the wild jujubes can be further improved. Finally, the remaining large branches or other large sundries fall out through the coarse sieve holes 13 provided on the waste barrel 7, and are collected in the fourth collection chamber 17 provided in the aggregate mechanism 4, and are discharged through the discharge port 21.

[0040] Embodiment 2 On the basis of Embodiment 1, as Figure 3 and Figure 4 shown, the previous process is connected through the conveying mechanism 30. The roller 27 rotates on the chassis 5, driving the feeding mechanism 28 to move together with the roller 27. When it moves to the left side, the picked wild jujubes are continuously supplied to the corresponding feeding mechanism 28 through the conveying mechanism 30. Then, the feeding mechanism 28 is continuously driven to move until it moves to the topmost position. The feeding mechanism 28 can no longer intercept the vertical movement of the wild jujubes, and under its own gravity, the wild jujubes fall into the guide trough at the top. The spiral plate 26 rotates on the chassis 5, so that the spiral plate 26 contacts the wild jujubes, realizing the feeding of the wild jujubes. And the whole process is through mechanical transmission, without the need for workers to continuously put the picked wild jujubes into the guide plate 25, thereby improving the efficiency of screening wild jujubes and reducing the labor intensity of workers.

[0041] Embodiment 3 On the basis of Embodiment 2, asFigures 3 - 6 As shown, during the feeding process, the second motor 56 drives the driving wheel 57 to rotate, causing the arc-shaped block 59 provided on one side of the driving wheel 57 to slide out between several third columns 60, releasing the restriction on the rotation of the first driven wheel 54 on the chassis 5. At the same time, the dial rod 58 contacts the fourth column 61 on one of the second driven wheels 55, and the generated component force drives the second driven wheel 55 to rotate on the chassis 5, thereby driving the roller 36 to rotate on the chassis 5, causing the inclined plate 37 provided on the roller 36 to drive the wild jujubes to move above the fine sieve holes 34. At this time, due to the downward inclination of the inclined plate 37, the wild jujubes on the inclined plate 37 fall above the fine sieve holes 34; After further rotating the driving wheel 57, the arc-shaped block 59 will contact multiple fourth columns 61, restricting the rotation of the second driven wheel 55 on the chassis 5, preventing the second driven wheel 55 from being inadvertently driven to rotate by an external force, which may cause the roller 36 to rotate on the chassis 5, resulting in the premature dropping of the wild jujubes on the inclined plate 37 and affecting the normal feeding of subsequent wild jujubes. Furthermore, it ensures the stability of the overall structure and improves the efficiency of screening wild jujubes. At the same time, the dial rod 58 contacts one of the third columns 60 on the first driven wheel 54, and the generated component force drives the first driven wheel 54 to rotate on the chassis 5, driving the conveyor belt 35 to move on the chassis 5, causing the picked wild jujubes to move to the end of the conveyor belt 35 and fall onto the inclined plate 37 on one side of the conveyor belt 35. Since the inclined plate 37 is inclined upward at this time, it prevents the wild jujubes from falling off the roller 36; Repeating the above steps multiple times will alternately drive the roller 36 and the conveyor belt 35 to rotate. When the driving wheel 57 drives the conveyor belt 35 to rotate and drives the wild jujubes to move forward and fall onto the roller 36, the rotation of the roller 36 is restricted by the arc-shaped block 59, preventing the wild jujubes from falling due to contact with the rotating roller 36 or not falling on the predetermined inclined plate 37, thereby improving the feeding efficiency of the wild jujubes. At the same time, when the driving wheel 57 drives the roller 36 to rotate and conveys the wild jujubes to the feeding mechanism 28, the movement of the conveyor belt 35 is restricted by the arc-shaped block 59, preventing the wild jujubes from falling due to not falling on the predetermined inclined plate 37, further improving the feeding efficiency of the wild jujubes. In addition, by adjusting the rotation speed of the second motor 56, the feeding rate of the conveying mechanism 30 is controlled to ensure that the materials falling from the roller 36 fall on the fine sieve holes 34 provided between the fixed roller 32 and the movable roller 33. At the same time, the leaves or other smaller impurities mixed with the wild jujubes, as well as the smaller wild jujubes, will pass through the fine sieve holes 34 formed between the fixed roller 32 and the movable roller 33 and fall into the recycling box 38 provided on the chassis 5, thereby realizing the preliminary screening of the wild jujubes, removing the impurities such as leaves and soil on the wild jujubes, reducing the burden of subsequent cleaning and screening, and further improving the efficiency of screening the wild jujubes; When it is necessary to change the size of the initially screened wild jujubes, the first motor 50 drives the drive gear 51 to rotate, transmits the torque through the driven gear 52, drives the first rotating shaft 43 to rotate on the chassis 5, thereby driving the shifting blocks 44 provided at both ends of the first rotating shaft 43 to move together. At the same time, it drives the connecting rod 48 provided on the other side of the shifting block 44 to rotate, and the second upright post 49 on the connecting rod 48 first contacts the limiting block 45, driving the limiting block 45 to move on the drum 27 until the convex block 46 provided on one side of the limiting block 45 slides out from between the adjacent first upright posts 42, thereby releasing the restriction on the rotation of the turntable 40 on the drum 27. Then, by the shifting block 44 contacting one of the first upright posts 42 and driving it to move to the position where the previous adjacent first upright post 42 was located, the turntable 40 is driven to rotate on the drum 27, so that the inclined slot 41 provided on the turntable 40 further contacts the movable roller 33. At the same time, through the sliding connection between the vertical slot 39 and the movable roller 33, it plays a guiding role in the sliding of the movable roller 33 on the vertical plate 31, thereby driving the movable roller 33 to move between the two vertical plates 31 in a specified direction, thereby adjusting the size of the fine sieve holes 34, changing the size of the initially screened wild jujubes, putting the smaller wild jujubes into the recycling box 38, and further improving the quality of the screened wild jujubes.

[0042] Embodiment 4 On the basis of Embodiment 1, as Figure 3 shown, the third motor 65 drives the third rotating shaft 67 to rotate on the chassis 5, driving the first gear 68 and the second gear 69 to rotate together on the chassis 5. Since the end of the second rotating shaft 66 is provided with a third gear 70, and the fourth gear 71 that is rotatably connected to the chassis 5 and meshes with both the first gear 68 and the third gear 70 is provided, the second rotating shaft 66 is driven to rotate together on the chassis 5. Since the second rotating shaft 66 is connected to the sieve barrel 1, the sieve barrel 1 is driven to rotate on the chassis 5, realizing the cleaning and screening of wild jujubes; At the same time, since the sixth gear 74 provided at the end of the fourth rotating shaft 72 meshes with the second gear 69, the spiral plate 26 connected to the fourth rotating shaft 72 is driven to rotate on the chassis 5, and contacts the wild jujubes through the spiral plate 26, realizing the continuous feeding of wild jujubes; In addition, since the fifth gear 73 provided on the chassis 5 meshes with the rack 75 provided on the drum 27, the drum 27 will be driven to rotate on the chassis 5, so that through the third motor 65, the sieve barrel 1, the spiral plate 26 and the drum 27 are simultaneously driven to rotate on the chassis 5, without the need to separately set up a power device, further reducing the cost required for the installation of the power device and the space required for manufacturing; In addition, by adjusting the tooth number ratio among the first gear 68, the third gear 70 and the fourth gear 71, the transmission ratio between the second rotating shaft 66 and the third rotating shaft 67 is changed, thereby adjusting the speed ratio of the rotation of the screening barrel 1 and the spiral plate 26, regulating the balance between feeding and screening and cleaning, ensuring the screening and cleaning efficiency, and improving the quality of wild jujubes after screening and cleaning. Additionally, by fixing the speed ratio of the roller 27 and the spiral plate 26, it is ensured that the feeding of the roller 27 and the feeding of the spiral plate 26 are in a balanced state, preventing materials from accumulating in the material guiding plate 25, increasing the working burden of driving the spiral plate 26 to rotate, or delaying the supply of materials into the material guiding plate 25, reducing the feeding efficiency of wild jujubes, and thus improving the screening and cleaning efficiency of wild jujubes.

[0043] Example 5 On the basis of Example 1, as Figures 7 - 11 shown, in the initial state, the first valve 76 and the fourth valve 79 are open, and the second valve 77 and the third valve 78 are closed. At this time, the first discharge port 19 is in an open state, and the second discharge port 20 is in a closed state. The wild jujubes in the second collection chamber 15 no longer fall into the first discharge port 19, while the wild jujubes in the third collection chamber 16 fall into the second discharge port 20, so that only the wild jujubes from the first discharge port 19 are collected, and the second discharge port 20 is in a closed state to prevent the screened wild jujubes from falling. When there are no longer screened wild jujubes in the first discharge port 19 and there are enough wild jujubes collected in the second discharge port 20, it is necessary to close both the first discharge port 19 and the second discharge port 20 simultaneously. Specifically, the telescopic cylinder 96 drives the third slider 87 to slide on the chassis 5, so that the first inclined surface 85 provided on the first wedge block 88 contacts one side of the wedge-shaped groove 90, and the generated component force drives the first slider 83 to slide on the chassis 5 until the first inclined surface 85 provided at its end contacts one of the valve plates 80 of the first valve 76, driving this valve plate 80 to rotate on the first discharge port 19, and transmitting torque through the fifth rotating shaft 81 to drive one of the seventh gears 82 to rotate. Since two adjacent seventh gears 82 are meshed with each other, the remaining adjacent valve plates 80 are simultaneously driven to rotate in the opposite direction, so that the two valve plates 80 on the first valve 76 are simultaneously closed, preventing the subsequent wild jujubes in the first discharge port 19 from falling, and simultaneously opening the two valve plates 80 on the second valve 77, so that the wild jujubes fall from the first collection chamber 14 into the first discharge port 19. Additionally, at this time, the end of the second slider 84 contacts the end surface of the second wedge block 89, so that the first slider 83 continuously contacts the valve plate 80 of the third valve 78, thereby closing both the first discharge port 19 and the second discharge port 20 simultaneously, preventing the wild jujubes from falling from the first discharge port 19 or the second discharge port 20 during the process of the movable frame 22 driving the collection barrel 23 to move, and thus reducing the loss of qualified wild jujubes during the screening process. Then, by rotating the screw rod 64 on the chassis 5, the movable frame 22 is driven to slide on the chassis 5, and the collection bucket 23 on the movable frame 22 is driven to move to one side, and another collection bucket 23 is replaced. Then, the screw rod 64 is continuously rotated, so that the new collection bucket 23 moves below the second discharge port 20. Then, the telescopic cylinder 96 drives the third slider 87 to slide reversely on the chassis 5, so that the fourth inclined surface 92 provided on one side of the first wedge block 88 contacts the other side of the wedge groove 90, continuously keeping the first valve 76 closed and the second valve 77 open. In addition, during the movement of the third slider 87, the second wedge block 89 is driven to move at the same time, so that the second slider 84 no longer contacts the second wedge block 89, and the second wedge block 89 is further moved until the fifth inclined surface 93 provided on one side of the second wedge block 89 no longer contacts the second slider 84. Under the resilience of the second tension spring 95, the second sliding plate is reset, and the restriction on the opening of the third valve 78 is released. Under the action of the self-weight of the wild jujubes in the second bin on the valve plate 80 of the third valve 78, the valve plate 80 of the third valve 78 is pushed to rotate in the second bin. Similarly, through the cooperation of the fifth rotating shaft 81 and the seventh gear 82, the valve plate 80 of the fourth valve 79 is driven to close, intercepting the subsequent wild jujubes from entering the second discharge port 20 from the third collection cavity 16, thereby slowing down the height of the continuous fall of the wild jujubes and reducing the damage caused during the fall of the wild jujubes, and improving the quality of the screened wild jujubes; Repeat the above steps multiple times, simultaneously realizing the switching of the opening and closing of the first discharge port 19 and the second discharge port 20, and there is no need to separately set a power device to control the opening and closing of the first valve 76, the second valve 77, the third valve 78 and the fourth valve 79. Furthermore, the space required for the installation of the power device and the cost required for manufacturing are reduced, and at the same time, the programming difficulty of controlling the opening and closing of the first valve 76, the second valve 77, the third valve 78 and the fourth valve 79 is reduced.
