DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] Embodiment 1

[0036] See also Figure 1-4 , a rotary screw conveyor for agricultural production, comprising a conveying mechanism 1, the conveying mechanism 1 comprises a conveying pipe 11 and a working frame, the conveying pipe 11 is erected on the working frame, a conveying motor 12 is arranged at the end of the conveying pipe 11, the output end of the conveying motor 12 is movable and penetrates into the interior of the conveying pipe 11, the output end of the conveying motor 12 is fixedly connected with a conveying spiral sheet 13, a drop hole 15 is opened at the bottom of the conveyor near the end, a storage bin 2 is fixedly connected to the top of the conveyor body, a cleaning component 3 is arranged at the top of the storage bin 2, the cleaning component 3 comprises a working box 31 fixedly connected to the top of the storage bin 2, a collection box 32 is arranged inside the working box 31, a filter residue net 33 is arranged inside the collection box 32, the filter residue net 33 is truncated, and the top surface area is slightly smaller, a plurality of filter residue holes are also opened at the outer end of the collection box 32 near the bottom, and the dust is screened out in cooperation with the filter residue net 33, and a vibration component 4 is arranged on the filter residue net 33, and the vibration component 4 is used to drive the filter residue net 33 to rotate and shake at the same time;

[0037] In this case, a plurality of evenly distributed dust filter grooves can be provided at the inner bottom of the conveying pipe 11 to help further clean up some materials that have not been cleaned up.

[0038] See also Figure 6 A slag discharge component 5 is arranged under the filter residue net 33, and the slag discharge component 5 includes a slag receiving plate 51, and a control component 6 is arranged on the slag receiving plate 51; the control component 6 has two states: the first state is to pull up the slag receiving plate 51, so that it tilts upward to discharge slag and slides to the bottom; the second state is to lower the slag receiving plate 51, so that it tilts downward and slides to reset; a sinking component 7 is also arranged on the filter residue net 33, and the sinking component 7 is responsible for sinking the filter residue net 33 after the slag receiving plate 51 slides down, leaving a gap so that the material falls into the storage bin 2.

[0039] The outer end of the working box 31 is fixedly connected to the feed hopper 10 , and the top of the collecting box 32 is fixedly connected to the feed hopper 10 .

[0040] When the staff transports some crops, some crops such as peanuts will be stained with a small amount of soil or dust. When transported by the conveyor, not only will the soil attached to the material be conveyed to the storage bag, but a large amount of dust will also be generated at the outlet. Therefore, the material needs to be cleaned first. By setting a truncated cone-shaped filter net 33 and vibrating the filter net 33, the soil can be screened out, and the generated soil falls to the slag receiving plate 51. Subsequently, the soil on the slag receiving plate 51 can be poured onto the outer wall of the device. During the slag pouring process, the filter net 33 can also be driven to sink. There will be a certain gap between the filter net 33 and the aggregate box 32. The material on the filter net 33 will be poured into the storage bin 2 and transported upward layer by layer by the rotating conveying spiral blade 13 until it is transported to the highest point and collected by the storage bag.

[0041] In order not to affect the working efficiency of the conveying mechanism 1, the cleaning component 3 can be made to work for a period of time. When the storage bin 2 is full of materials, the conveying motor 12 is driven to start conveying the materials upward.

[0042] See also Figure 4-5 In an embodiment further provided by the present invention, the vibration component 4 also includes a reduction motor 41, the output end of the reduction motor 41 is fixedly connected to a square shaft 42, the outer end of the square shaft 42 is slidably connected to a driving shaft 43, the top of the driving shaft 43 is provided with a square groove, so that the square shaft 42 can slide in the square groove, the bottom of the driving shaft 43 is fixedly connected to the top of the filter residue net 33, the outer end of the driving shaft 43 is fixedly connected to a plurality of vibration rods 44, the ends of the vibration rods 44 are rotatably connected to rollers 45, a pair of limiting rings 46 are arranged on the outside of the driving shaft 43, an annular groove 47 is provided on the inner side of the limiting ring 46, and a plurality of protrusions 48 are fixedly connected to the inner bottom of the annular groove 47; the outer wall of the filter residue net 33 is fixedly connected to a rotating plate 34.

[0043] The sinking component 7 includes a bidirectional screw rod 71 rotatably connected to the top of the aggregate box 32, a movable sleeve 72 is threadedly sleeved on the outer end of the bidirectional screw rod 71, a transmission rod 73 is fixedly connected between the movable sleeve 72 and the limiting ring 46, a plurality of telescopic rods 74 are fixedly connected between the limiting ring 46 and the inner top of the working box 31, and a transmission component 8 is arranged on the top of the bidirectional screw rod 71, which is responsible for driving the bidirectional screw rod 71 to rotate.

[0044] The reduction motor 41 is turned on, and the reduction motor 41 rotates the square shaft 42, and the square shaft 42 causes the driving shaft 43 to rotate continuously. Since the filter residue net 33 also rotates continuously with the rotating plate 34, the material is forced to rotate slowly, and the soil is peeled off by the friction between them. In addition, a vibration rod 44 and a roller 45 are also connected to the driving shaft 43. When the roller 45 rolls in the annular groove 47, it touches the protrusion 48 and will roll over the protrusion 48, giving the vibration rod 44 a shaking force, so that the vibration rod 44 shakes intermittently during the rotation process. As a result, the filter residue net 33 can be repeatedly shaken while rotating to clean the soil on the material, and the detached dust falls to the slag receiving plate 51 through the filter residue holes of the aggregate box 32 and the filter residue net 33, and is collected by the slag receiving plate 51.

[0045] Due to the limitation of the bidirectional screw rod 71, the initial position of the limiting ring 46 remains unchanged.

[0046] When the bidirectional screw rod 71 rotates, the drive shaft 43 and the filter residue net 33 connected thereto can be moved downward, so that a gap begins to form between the filter residue net 33 and the aggregate box 32, and this gap will become larger and larger, and the material will begin to fall rapidly into the storage bin 2.

[0047] In the embodiment further provided by the present invention, the slag discharge component 5 also includes a pair of sliders 53, the slag receiving plate 51 is a drawer-type structure, one side and the top are open, a guide groove 52 is provided on the top of the slag receiving plate 51, the slider 53 is slidably connected to the inner wall of the guide groove 52, and a pulling rod 54 is fixedly connected between the pair of sliders 53; a slag pouring trough is provided on the left side of the working box 31, and a pile of supporting protrusions 48 are arranged on the slag pouring trough. The supporting protrusions 48 are made of smooth curved surface material, which not only supports the slag receiving plate 51, but also facilitates the slag receiving plate 51 to slide on it.

[0048] See also Figure 8 The control component 6 includes a plurality of traction members 61 fixedly connected to the outer end of the pulling rod 54, the traction member 61 is a steel wire rope (or other tough thin rope), a pair of support frames 62 are fixedly connected to the top of the working box 31, a roller 63 is fixedly connected between the pair of support frames 62, one end of the plurality of traction members 61 is fixedly connected to the outer wall of the roller 63, a gear sleeve 64 is fixedly sleeved on the outer wall of the roller 63, a driving component 9 is arranged below the roller 63, and the driving component 9 is responsible for driving the roller 63 to rotate; the slag receiving plate 51 is fixedly connected to a counterweight near the bottom of the storage bin 2, the counterweight can be a metal solid with a mass of 1-5 kg, which helps to balance the two ends of the slag receiving plate 51.

[0049] When it is necessary to start slag discharge, the roller 63 can be rotated. During the rotation of the roller 63, the traction member 61 is pulled, and the traction member 61 pulls the traction rod 54 up a short distance, so that the slag receiving plate 51 starts to tilt. After the tilt, the slag receiving plate 51 starts to slide downward. At this time, the traction rod 54 slides with the slider 53 in the guide groove 52, and the dust on the slag receiving plate 51 falls outside the device, so as to achieve the purpose of intermittent soil discharge.

[0050] The slag receiving plate 51 continues to slide until it slides to the bottom. At this time, there is no obstruction of the slag receiving plate 51 below the filter residue net 33, and the filter residue net 33 can be smoothly moved down to discharge the materials thereon.

[0051] See also Figure 8-10 In the solution further provided by the present invention, the driving component 9 includes a first reduction gear 91 fixedly sleeved on the output end of the reduction motor 41, the top of the working box 31 is rotatably connected to a driven shaft 92, the outer ends of the driven shaft 92 are respectively fixedly sleeved with a second reduction gear 93 and an eccentric wheel 94, the first reduction gear 91 is meshed with the second reduction gear 93, there is a large gear ratio between the first reduction gear 91 and the second reduction gear 93, the gear ratio range is 1:10-20 (this case will take 1:18 as an example later, The top surface of the working box 31 is provided with a friction groove, on which a friction block is slidably connected, and the top of the friction block is fixedly connected to the gear bar 95, so that there is sliding damping between the working box 31 and the gear bar 95, and the outer edge of the gear sleeve 64 is meshingly connected to the gear bar 95, and the end of the gear bar 95 is fixedly connected to a push-pull plate 96, which is an arc-shaped structure, and the angle range of the arc is 120-180 degrees (this case will take 120 degrees as an example to describe the subsequent working process).

[0052] A fixing column 97 is fixedly connected to the top of the eccentric wheel 94 , and a pulling rope 98 is fixedly connected between the fixing column 97 and the push-pull plate 96 . When the fixing column 97 is located at the farthest end of the push-pull plate 96 , the pulling rope 98 is in a straightened state.

[0053] In the solution further provided by the present invention, the transmission component 8 includes an incomplete gear 81 fixedly sleeved on the driven shaft 92, the top of the working box 31 is rotatably connected with the transmission shaft 82, the outer wall of the transmission shaft 82 is fixedly sleeved with the first transmission gear 83, the top of the bidirectional screw rod 71 is fixedly connected with the reduction shaft 84, the top of the reduction shaft 84 movably passes through the top of the working box 31, the outer end of the reduction shaft 84 is fixedly sleeved with the second transmission gear 85, the first transmission gear 83 is meshingly connected with the second transmission gear 85, the second transmission gear 85 has a gear ratio with the first transmission gear 83, and the gear ratio range is 1:5-10 (this case will take 1:8 as an example to describe the subsequent working process).

[0054] When the first reduction gear 91 rotates 6 circles following the driving shaft 43, the eccentric wheel 94 rotates 120 degrees from the initial position (this is the first stage), and then starts to rotate 120 degrees to first touch the push-pull plate 96 and push the push-pull plate 96 to start moving (this is the second stage). During the movement of the push-pull plate 96, the gear bar 95 slides and drives the gear sleeve 64 to rotate, and the driven roller 63 rotates, causing the slag receiving plate 51 to begin to tilt. The first reduction gear 91 continues to rotate 6 circles in the second stage, and the second reduction gear 93 also rotates 120 degrees until the push-pull plate 96 moves to the farthest distance. Then the first reduction gear 91 continues to rotate 6 circles, and the second reduction gear 93 also continues to rotate 120 degrees (this is the third stage). Due to the sliding damping between the working box 31 and the gear bar 95, the gear bar 95 does not move. In the third stage, the slag receiving plate 51 51 can not only discharge slag but also slide on the slag pouring chute until it slides to the bottom. In the second half of the third stage, the incomplete gear 81 begins to mesh with the first transmission gear 83, and rotates the first transmission gear 83 90 degrees, and drives the second transmission gear 85 through the first transmission gear 83, so that the second transmission gear 85 rotates 2 circles, which can just make the two-way screw rod 71 rotate 2 circles, and can just move the filter residue net 33 downward to discharge the material, and then automatically reset; the second reduction gear 93 finally rotates 120 degrees, and begins to pull the push-pull plate 96 to reset through the pulling rope 98. At this time, the pulling member begins to be lowered to the initial state. Under the action of the counterweight, the slag receiving plate 51 begins to tilt slightly downward (the tilt angle is 5-20), and the slag receiving plate 51 slides smoothly to the bottom of the filter residue net 33 and begins to collect the fallen dust.

[0055] A limiting plate is also fixedly connected to the inner wall of the actual working box 31 , and there is a resistance relationship between the right end of the slag receiving plate 51 and the limiting plate, so that the slag receiving plate 51 can be stabilized when tilted at a certain angle.

[0056] There is a pair of bidirectional screw rods 71, and the outer ends of a pair of reduction shafts 84 are fixedly sleeved with pulleys 75. The top of the working box 31 is also rotatably connected to a pair of movable shafts 76, and the outer ends of the movable shafts 76 are fixedly sleeved with tension pulleys 77. The outer walls of the pulleys 75 and the tension pulleys 77 are transmission-connected with transmission belts 78.

[0057] In order to make the filter residue net 33 more stable during the downward movement, a pair of bidirectional screw rods 71 ​​can be set. By setting a transmission belt 78, a pair of movable shafts 76 can be rotated, and finally the pair of bidirectional screw rods 71 ​​can be rotated synchronously to smoothly bring the filter residue net 33 down.

[0058] Embodiment 2

[0059] The difference between the second embodiment and the first embodiment is that the traction member 61 is a thin rod, a paddle is fixedly connected to the rotating roller 63, the paddle is movably connected to the thin rod, a movable block is rotatably connected to the top of the thin rod, the movable block is slidably connected to the paddle, and the bottom of the thin rod is rotatably connected to the rotating roller 63. The other structures are the same as those of the first embodiment.

[0060] This embodiment does not require a counterweight. When the roller 63 starts to rotate clockwise, the thin rod is pulled up, so that the slag receiving plate 51 can be tilted upward. Similarly, when the roller 63 rotates counterclockwise, the thin rod will be squeezed by the paddle, so that the slag receiving plate 51 tilts downward and finally slides to the initial position.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
