By rotating the spiral plate 26 on the guide plate 25, the sour jujube is gradually pushed to move on the guide plate 25, so as to avoid the sour jujube blocking the guide plate 25 and affecting the subsequent normal feeding, thereby improving the efficiency of screening sour jujube; it also includes a roller 27 rotatably arranged on the base frame 5, the guide plate 25 is arranged on the top of the base frame 5, and a plurality of groups of material-dipping mechanisms 28 are provided on the roller 27, and a plurality of feeding ports 29 used in conjunction with the material-dipping mechanism 28 and the guide plate 25 are provided on the roller 27; it also includes a conveying mechanism 30 arranged on the base frame 5 and used in conjunction with the material-dipping mechanism 28, which is connected to the conveying mechanism 30 through the conveying mechanism 30. Continuing the previous process, the roller 27 rotates on the base frame 5, driving the material-dispensing mechanism 28 to move along with the roller 27. When it moves to the left, the picked sour dates are continuously supplied to the corresponding material-dispensing mechanism 28 through the conveying mechanism 30, and then the material-dispensing mechanism 28 is continuously driven to move until it moves to the top. The material-dispensing mechanism 28 can no longer intercept the sour dates from moving vertically, and under the action of its own gravity, it falls into the material guide trough at the top, and rotates on the base frame 5 through the spiral plate 26, so that the spiral plate 26 contacts the sour dates, realizing the feeding of the sour dates.

The first driven wheel 54 and the second driven wheel 55 are driven to rotate on the chassis 5 in sequence. The arc block 59 contacts with the third columns 60 and the fourth columns 61 in sequence, which restricts the first driven wheel 54 and the second driven wheel 55 from rotating on the chassis 5 in sequence. The driving wheel 57 is driven to rotate by the second motor 56, so that the arc block 59 provided on one side of the driving wheel 57 slides out from between the third columns 60, releasing the restriction on the rotation of the first driven wheel 54 on the chassis 5. At the same time, the lever 58 contacts with the fourth column 61 on one of the second driven wheels 55, generating a force component. The second driven wheel 55 is driven to rotate on the base frame 5. After the driving wheel 57 is further rotated, the arc block 59 will contact multiple fourth columns 61, limiting the rotation of the second driven wheel 55 on the base frame 5, preventing external force from accidentally driving the second driven wheel 55 to rotate, causing the roller 36 to rotate on the base frame 5, causing the hawthorns on the inclined plate 37 to fall off prematurely, affecting the normal feeding of subsequent hawthorns, thereby ensuring the stability of the overall structure and improving the efficiency of screening hawthorns; at the same time, the lever 58 contacts one of the third columns 60 on the first driven wheel 54, and the component force generated drives the first driven wheel 54 to rotate on the base frame 5.

[0052] Preferably, Figure 7-11As shown, the base frame 5 is slidably connected to a first slider 83 and a second slider 84. The ends 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 contact the first valve 76 and the second valve 77. The base frame 5 is slidably connected to a third slider 87. The third slider 87 is provided with a first wedge block 88 and a second wedge block 89. The end of the first slider 83 is provided with a wedge groove 90. 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 contact the wedge groove 90.

Since the two adjacent seventh gears 82 are engaged with each other, the remaining adjacent valve plates 80 are driven to rotate in the opposite direction at the same time, so that the two valve plates 80 on the first valve 76 are closed at the same time, avoiding the subsequent first discharge port 19. The sour jujubes in the material port 19 continue to fall, and at the same time, the two valve plates 80 on the second valve 77 are opened, so that the sour jujubes fall from the first collecting chamber 14 into the first discharge port 19; in addition, 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 continues to contact the valve plate 80 of the third valve 78, thereby closing the first discharge port 19 and the second discharge port 20 at the same time, preventing the sour jujubes from falling from the first discharge port 19 or the second discharge port 20 during the movement of the collection barrel 23 driven by the movable frame 22, thereby reducing the loss of qualified sour jujubes during the screening process;

[0053] 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 in the opposite direction on the base frame 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, and the first valve 76 is continuously kept closed and the second valve 77 is opened; in addition, the third slider 87 simultaneously drives the second wedge block 89 to move, 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 action of the rebound force of the second tension spring 95, the second slide plate is reset, and the restriction on the opening of the third valve 78 is released. The weight of the sour jujubes in the second hopper acts on the valve plate 80 of the third valve 78, pushing the valve plate 80 of the third valve 78 to rotate in the second hopper. 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 sour jujubes from entering the second discharge port 20 from the third collecting chamber 16, thereby slowing down the height of the sour jujubes falling continuously, reducing the damage caused by the sour jujubes falling during the process, and improving the quality of the sour jujubes after screening;

[0054] Repeat the above steps multiple times to realize the switching of opening and closing of the first discharge port 19 and the second discharge port 20 at the same time, and there is no need to set up a separate 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 installing the power device and the manufacturing cost, 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.

[0055] Example 1

[0056] The present invention provides a device for screening and packaging sour jujube, such as Figure 1 and Figure 2 As shown, by rotating the spiral plate 26 on the guide plate 25, the sour jujube is gradually pushed to move on the guide plate 25, so as to avoid the sour jujube blocking the guide plate 25 and affecting the subsequent normal feeding, thereby improving the efficiency of screening sour jujube;

[0057] When the sour jujube enters the cleaning cylinder 6, the sour jujube in the cleaning cylinder 6 is sprayed by the spray gun 24, and the screen barrel 1 rotates on the base frame 5 to drive the sour jujube in the cleaning cylinder 6 to roll continuously, so that the spray gun 24 can fully spray the surface of the sour jujube to avoid that some areas of the sour jujube are located on the lower side and cannot be cleaned, thereby improving the cleaning effect of the sour jujube and improving the quality of the sour jujube after production. At the same time, the cleaned sewage is collected into the first collecting chamber 14 provided in the collecting mechanism 4 through the filtering water hole 10, and is discharged to the outside through the drain port 18; then the sour jujube passes through the first screening cylinder 8 and the second screening cylinder 9 in turn, and the sour jujubes of the same size pass through the first sieve hole 11 and the second sieve hole 12 provided in the first screening cylinder 8 and the second screening cylinder 9 respectively, and are collected into the second collecting chamber 15 or the third collecting chamber 16 provided in the collecting mechanism 4, thereby achieving the sour jujube The screening and cleaning mechanisms are both arranged on the screening barrel 1, which can perform screening and cleaning work in sequence, without the need to clean and screen the jujube separately, thereby reducing the transportation steps required in the intermediate process and improving the efficiency of producing jujube. At the same time, the screening barrel 1 rotates on the base frame 5 to prevent the jujube from staying in one place for a long time and blocking the first sieve hole 11 or the second sieve hole 12, thereby improving the screening efficiency of jujube. When the number reaches a certain level, the movable seat slides on the base frame 5, driving the collecting barrel 23 to slide on the base frame 5, and slides to the bottom of the first discharge port 19 or the second discharge port 20 respectively, and moves the screened jujube to the next process. In addition, several groups of screening barrels can be provided according to actual needs, with sieve holes of different sizes, to further realize multi-stage screening of jujube, and further improve the effect of jujube screening.

[0058] Finally, the remaining large branches or other large debris fall out through the coarse sieve holes 13 provided on the waste bucket 7 and are collected in the fourth collecting chamber 17 provided on the collecting mechanism 4 and discharged from the discharge port 21.

[0059] Example 2

[0060] On the basis of Example 1, Figure 3 and Figure 4 As shown, the previous process is connected through the conveying mechanism 30, and the roller 27 rotates on the base frame 5, driving the material-dispensing mechanism 28 to move with the roller 27. When it moves to the left, the picked sour dates are continuously supplied to the corresponding material-dispensing mechanism 28 through the conveying mechanism 30, and then the material-dispensing mechanism 28 is continuously driven to move until it moves to the top. The material-dispensing mechanism 28 can no longer intercept the sour dates from moving vertically, and under the action of its own gravity, it falls into the material guide trough at the top, and rotates on the base frame 5 through the spiral plate 26, so that the spiral plate 26 is in contact with the sour dates, realizing the feeding of the sour dates. The whole process is mechanically driven, and there is no need to manually put the picked sour dates into the material guide plate 25, thereby improving the efficiency of screening sour dates and reducing the labor intensity of workers.

[0061] Example 3

[0062] On the basis of Example 2, Figure 3-Figure 6 As shown, during the feeding process, the driving wheel 57 is driven to rotate by the second motor 56, so that the arc block 59 provided on one side of the driving wheel 57 slides out from between the plurality of third columns 60, releasing the restriction on the rotation of the first driven wheel 54 on the base frame 5, and at the same time, the lever 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 base frame 5, thereby driving the roller 36 to rotate on the base frame 5, so that the inclined plate 37 provided on the roller 36 drives the sour jujube to move above the fine sieve holes 34. At this time, since the inclined plate 37 is tilted downward, the sour jujube on the inclined plate 37 falls above the fine sieve holes 34;

[0063] After the driving wheel 57 is further rotated, the arc block 59 will contact multiple fourth columns 61, limiting the second driven wheel 55 from rotating on the base frame 5, preventing external force from accidentally driving the second driven wheel 55 to rotate, causing the roller 36 to rotate on the base frame 5, causing the sour dates on the inclined plate 37 to fall off in advance, affecting the normal loading of subsequent sour dates, thereby ensuring the stability of the overall structure and improving the efficiency of screening sour dates; at the same time, the lever 58 contacts one of the third columns 60 on the first driven wheel 54, and the component force generated drives the first driven wheel 54 to rotate on the base frame 5, driving the conveyor belt 35 to move on the base frame 5, so that the picked sour dates 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 angle of the inclined plate 37 is tilted upward at this time, the sour dates are prevented from falling from the roller 36;

[0064] Repeat the above steps several times, alternately drive the roller 36 and the conveyor belt 35 to rotate, so that the driving wheel 57 drives the conveyor belt 35 to rotate, and drives the sour jujube to move forward and fall onto the roller 36. The arc block 59 limits the rotation of the roller 36 to prevent the sour jujube from contacting the rotating roller 36 and falling, or not falling on the predetermined inclined plate 37 and falling, thereby improving the efficiency of sour jujube feeding. At the same time, the driving wheel 57 drives the roller 36 to rotate, and when the sour jujube is transported to the material diverting mechanism 28, the arc block 59 limits the movement of the conveyor belt 35 to prevent the sour jujube from not falling on the predetermined inclined plate 37 and falling, further improving the efficiency of sour jujube feeding. efficiency; in addition, by adjusting the speed of the second motor 56, the feeding rate of the conveying mechanism 30 is controlled to ensure that the material dropped by the roller 36 falls on the fine sieve hole 34 provided between the fixed roller 32 and the movable roller 33, and at the same time, the leaves or other smaller impurities mixed with the sour jujube, and the smaller sour jujube will pass through the fine sieve hole 34 formed between the fixed roller 32 and the movable roller 33 and fall into the recovery box 38 provided on the chassis 5, thereby achieving the preliminary screening of the sour jujube, removing impurities such as leaves and soil on the sour jujube, reducing the burden of subsequent cleaning and screening, and further improving the efficiency of screening the sour jujube;

[0065] When the size of the initially screened sour jujube needs to be changed, 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 shifting blocks 44 provided at both ends of the first rotating shaft 43 to move together, and at the same time drives the connecting rod 48 provided on the other side of the shifting 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 rotation restriction of the turntable 40 on the roller 27, and then the shifting block 44 is used to rotate. It contacts one of the first columns 42, driving it to move to the position where the adjacent previous first column 42 was located, thereby driving the turntable 40 to rotate on the drum 27, so that the inclined groove 41 provided on the turntable 40 further contacts the movable roller 33, and at the same time, through the vertical groove 39 and the sliding connection with the movable roller 33, it guides the sliding of the movable roller 33 on the vertical plate 31, thereby driving the movable roller 33 to move in the specified direction between the two vertical plates 31, thereby adjusting the size of the fine sieve hole 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.

[0066] Example 4

[0067] On the basis of Example 1, Figure 3 As shown, the third rotating shaft 67 is driven to rotate on the chassis 5 by the third motor 65, driving the first gear 68 and the second gear 69 to rotate together on the chassis 5. Since the third gear 70 is provided at the end of the second rotating shaft 66, the chassis 5 is rotatably connected to the fourth gear 71 that is engaged with the first gear 68 and the third gear 70 at the same time, driving the second rotating shaft 66 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, thereby achieving the cleaning and screening of the sour jujube.

[0068] At the same time, since the sixth gear 74 provided at the end of the fourth rotating shaft 72 is engaged with the second gear 69, the spiral plate 26 connected to the fourth rotating shaft 72 is driven to rotate on the base frame 5, and the spiral plate 26 contacts the sour jujube, thereby realizing continuous feeding of the sour jujube;

[0069] In addition, since the fifth gear 73 provided on the base frame 5 is engaged with the rack 75 provided on the drum 27, the drum 27 is driven to rotate on the base frame 5, thereby driving the screen barrel 1, the spiral plate 26 and the drum 27 to rotate on the base frame 5 at the same time through the third motor 65, there is no need to provide a separate power device, further reducing the cost required for installing the power device and the space required for manufacturing;

[0070] In addition, by adjusting the gear ratio between 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 then the speed ratio of the screen barrel 1 and the spiral plate 26 is adjusted, and the balance between feeding and screening and cleaning is adjusted to ensure the screening and cleaning efficiency, while improving the quality of the sour jujube 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 guide plate 25, increasing the workload of driving the spiral plate 26 to rotate, or delaying the supply of materials to the guide plate 25, reducing the efficiency of sour jujube feeding, and thus improving the efficiency of sour jujube screening and cleaning.

[0071] Example 5

[0072] On the basis of Example 1, Figure 7-11 As 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 sour jujubes in the second collecting chamber 15 no longer fall into the first discharge port 19, while the sour jujubes in the third collecting chamber 16 fall into the second discharge port 20, so that only the sour jujubes from the first discharge port 19 are collected, and the second discharge port 20 is in a closed state, so as to avoid the sour jujubes after screening from falling.

[0073] When there are no more screened sour dates at the first discharge port 19 and there are enough sour dates at the second discharge port 20, it is necessary to close the first discharge port 19 and the second discharge port 20 at the same time. Specifically, the telescopic cylinder 96 drives the third slider 87 to slide on the base frame 5, so that the first inclined surface 85 provided on the first wedge block 88 contacts one side of the wedge groove 90, and the component force generated drives the first slider 83 to slide on the base frame 5 until the first inclined surface 85 provided on its end contacts 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 the two adjacent seventh gears 82 are meshed with each other, This simultaneously drives the remaining adjacent valve plates 80 to rotate in the opposite direction, so that the two valve plates 80 on the first valve 76 are closed at the same time, preventing the sour dates in the first discharge port 19 from continuing to fall, and at the same time opening the two valve plates 80 on the second valve 77, so that the sour dates fall from the first collecting chamber 14 into the first discharge port 19; in addition, 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 continues to contact the valve plate 80 of the third valve 78, thereby closing the first discharge port 19 and the second discharge port 20 at the same time, preventing the sour dates from falling from the first discharge port 19 or the second discharge port 20 during the movement of the collection barrel 23 driven by the movable frame 22, thereby reducing the loss of qualified sour dates during the screening process;

[0074] Then, by rotating the screw 64 on the base frame 5, the movable frame 22 is driven to slide on the base frame 5, and the collecting bucket 23 on the movable frame 22 is driven to move to one side, and another collecting bucket 23 is replaced. Then, the screw 64 is continuously rotated, so that the new collecting bucket 23 moves to the bottom of the second discharge port 20, and then the third slider 87 is driven by the telescopic cylinder 96 to slide in the opposite direction on the base frame 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, and the first valve 76 is continuously kept closed and the second valve 77 is opened; in addition, during the movement of the third slider 87, the second wedge block 89 is also driven to move, so that the second slider 84 is no longer in contact with the second wedge block 89, and further The second wedge block 89 is moved until the fifth inclined surface 93 provided on one side of the second wedge block 89 no longer contacts the second sliding block 84, and under the action of the rebound force of the second tension spring 95, the second slide plate is reset, and the restriction on the opening of the third valve 78 is released. The weight of the sour dates in the second hopper acts on the valve plate 80 of the third valve 78, pushing the valve plate 80 of the third valve 78 to rotate in the second hopper. Similarly, the cooperation of the fifth rotating shaft 81 and the seventh gear 82 drives the valve plate 80 of the fourth valve 79 to close, intercepting the subsequent sour dates from entering the second discharge port 20 from the third collecting chamber 16, thereby slowing down the height of the sour dates falling continuously, reducing the damage caused by the sour dates during the falling process, and improving the quality of the sour dates after screening;

[0075] Repeat the above steps multiple times to realize the switching of opening and closing of the first discharge port 19 and the second discharge port 20 at the same time, and there is no need to set up a separate 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 installing the power device and the manufacturing cost, 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.
