Description

Technical Field

[0001] The present invention relates to the technical field of agricultural grain storage and transportation devices, and in particular to a rice storage and transportation device in rice production. Background Art

[0002] Agricultural grains are generally stored inside granaries and can be directly transferred out from the granaries when needed. In order to facilitate transfer and use, a large number of grain storage devices are required inside the granaries, and the interior of the granaries requires strict fire and heat-proof sealing treatment.

[0003] The invention patent with authorization announcement number CN 112978112 B discloses a rice grain storage and transportation equipment for rice production, including a storage tank and a bracket assembly. The storage tank is provided in multiple groups, and the multiple groups of storage tanks are movably arranged on the bracket assembly. The storage tank includes a storage tank body, a tank cover, a connecting clip, and a universal caster. The tank cover is hingedly provided on the storage tank body, and a boss is provided on the tank cover, and a handle is provided on the boss. The connecting clip is centrally located at the bottom of the storage tank body. The universal casters are provided in multiple groups, and the multiple groups of universal casters are evenly spaced at the bottom of the storage tank body.

[0004] The above-mentioned device and most of the grain storage devices in the prior art all adopt the bottom discharge method when discharging. In order to lower the center of gravity and make the grain storage device more stable when moving, the distance between its bottom and the ground needs to be kept in a small range. This makes it very inconvenient to use vehicles and other transportation equipment to directly receive the grain inside the grain storage device. The grain output from the bottom of the grain storage device can only be lifted to a high position by a transfer equipment with a lifting function and then added to the vehicle. This is relatively inconvenient in actual use, increases the cost of the transfer equipment, and also requires a waste of manpower to carry and operate the equipment.

[0005] In addition, when the above-mentioned device is outputting rice, since the bottom of its inner cavity is flat, a small amount of rice may not be output naturally, and manual auxiliary output is required later.

[0006] Therefore, it is necessary to invent a rice storage and transportation device in rice production to solve the above problems. Summary of the Invention

The supporting plate is slidingly sleeved on the outside of the screw. One end of the second spring is fixedly connected to the lifting plate and the other end is fixedly connected to the supporting plate. The supporting plate is slidably nested in the storage tank along the vertical direction. A limiting ring is provided under the supporting plate, and the limiting ring is fixedly connected to the inner wall of the storage tank.

[0017] Preferably, the trigger-type discharging mechanism includes a rotating seat and an arc-shaped pushing plate;

[0018] The rotating seat is slidingly sleeved on the outside of the screw rod, and a plurality of arc-shaped pusher plates are provided, and the plurality of arc-shaped pusher plates are evenly fixedly arranged on the outside of the rotating seat.

[0020] The sealing cover is fixedly arranged inside the base shell, the air inlet pipe is arranged through the left side of the sealing cover, the second fixed collar is fixedly sleeved on the outside of the screw, and the semicircular sealing block is fixedly sleeved on the outside of the second fixed collar. There are two L-shaped ventilation pipes, extension pipes and valves. The two L-shaped ventilation pipes are fixedly arranged on both sides of the top of the sealing cover respectively. The L-shaped ventilation pipe passes through the lifting plate and the supporting plate, and the lifting plate and the supporting plate are slidably connected to the L-shaped ventilation pipe. A plurality of air holes are evenly opened on the outside of the L-shaped ventilation pipe. The two extension pipes are respectively connected to the two L-shaped ventilation pipes, and the two valves are respectively fixed at the output ends of the two extension pipes.

[0021] The present invention also provides a method for using a rice storage and transportation device in rice production, which specifically comprises the following steps:

[0022] S1, in the storage state, paddy is added to the storage tank through the feed hopper until the storage tank is full, and the feed hopper is closed. After storage is completed, the drive motor drives the screw to repeat the forward and reverse rotation operations. In addition, air is input into the sealing cover through the air inlet pipe. The semicircular sealing block seals the inlet of any L-shaped ventilation pipe under the drive of the screw. The air inside the sealing cover enters the inside of the other L-shaped ventilation pipe and enters the storage tank through the air holes on its surface to ventilate the paddy. The ventilated air enters the inside of the L-shaped ventilation pipe through the air holes on the L-shaped ventilation pipe with the opening blocked, and is then discharged through the extension pipe connected to the L-shaped ventilation pipe. Under the continuous rotation of the semicircular sealing block, the two L-shaped ventilation pipes repeat the air intake and exhaust operations;

[0023] S2. In the discharging state, the hydraulic cylinder drives its output shaft to extend and retract according to actual needs, and then the hydraulic cylinder drives the discharging pipe and the lifting adjustment plate to move up and down through the first fixed collar to adjust the discharging height of the discharging pipe. When the lifting adjustment plate moves, the second driving mechanism is driven to move up and down as a whole outside the screw through the lifting cross bar and the first connecting collar. Then, the stop valve on the discharging pipe is opened, and the rice located at the upper part of the inner cavity of the storage tank is discharged through the discharging pipe;

[0024] S3. After the rice in the upper part of the storage tank cavity is discharged, the drive motor is started. After the drive motor is started, the screw is continuously rotated, and the rotation of the screw drives the lifting plate to continuously rise. When the lifting plate rises, it first compresses the second spring, and then drives the supporting plate to rise synchronously. When the supporting plate rises, it lifts the rice in the storage tank, and the rice is discharged again through the discharge pipe;

[0025] S4. As the carrying plate continues to rise, the rice on the top of the carrying plate is continuously discharged. When the lifting distance of the lifting plate reaches the first threshold, the two positioning pins are respectively inserted into the two slots on the top of the rotating seat. At this time, the horizontal height of the arc-shaped pushing plate is higher than the horizontal height of the L-shaped ventilation pipe. At this time, the screw drives the lifting ring to rotate through the lifting shaft, and the lifting ring drives the rotating seat to rotate synchronously through the two positioning pins. The rotating seat drives multiple arc-shaped pushing plates to rotate, thereby pushing the small amount of rice remaining on the top of the carrying plate;

[0026] S5. When the lifting distance of the lifting plate reaches the second threshold, the supporting plate moves to below the inlet of the discharge pipe. At this time, the rice on the top of the supporting plate is pushed by multiple arc-shaped pushing plates and is all discharged from the discharge pipe.

[0027] Technical effects and advantages of the present invention:

[0028] The present invention is provided with an adjustable side discharging mechanism, a first driving mechanism, a second driving mechanism, a lifting mechanism, a trigger-type discharging mechanism and an alternating ventilation mechanism, so that the alternating ventilation mechanism can be driven by the feed hopper, thereby enabling the alternating ventilation mechanism to realize uninterrupted switching of air intake and air outlet during operation, thereby ensuring the uniformity of ventilation of the rice inside the storage tank. In addition, when discharging, the adjustable side discharging mechanism can be used for side discharging, and the second driving mechanism can be synchronously adjusted when the adjustable side discharging mechanism is used for discharging height adjustment, thereby enabling the subsequent first driving mechanism to adjust the lifting mechanism. During the driving process of the mechanism, the trigger-type discharging mechanism can be brought into contact with the second driving mechanism under the drive of the lifting mechanism, and then the second driving mechanism driven by the first driving mechanism drives the trigger-type discharging mechanism to output all the rice remaining in the storage tank. Compared with the same type of device in the prior art, the present invention can discharge the material from the side, which is convenient for vehicles and other transportation equipment to directly carry it. At the same time, the discharge height can be adjusted according to actual needs. In addition, the remaining rice can be effectively output without wasting manpower for auxiliary output, thereby reducing the use cost, saving manpower and having better actual use effect.

[0039] By setting the above structure, the hydraulic cylinder 44 can drive its output shaft to extend and retract according to actual needs, and then the hydraulic cylinder 44 drives the discharge pipe 42 and the lifting adjustment plate 41 to rise and fall through the first fixed ring 43, and adjusts the discharge height of the discharge pipe 42. When the lifting adjustment plate 41 moves, the second drive mechanism 6 is driven to rise and fall as a whole on the outside of the screw 52 through the lifting cross bar 45 and the first connecting ring 46, and then the stop valve on the discharge pipe 42 is opened, and the rice located in the upper part of the inner cavity of the storage tank 1 is discharged through the discharge pipe 42.

In addition, when the two positioning pins 63 are pushed from bottom to top during the rotation process, the positioning pins 63 can push the second connecting ring 65 and move it upward. At this time, the first spring 64 is stretched.

[0043] like Figure 4 As shown, the lifting mechanism 7 includes a lifting plate 71, a second spring 72, a supporting plate 73 and a limiting ring 74, wherein the lifting plate 71 is sleeved on the outside of the screw 52 and is threadedly connected to the screw 52, a plurality of second springs 72 are provided, and the supporting plate 73 is slidingly sleeved on the outside of the screw 52, one end of the second spring 72 is fixedly connected to the lifting plate 71 and the other end is fixedly connected to the supporting plate 73, the supporting plate 73 is slidably nested in the storage tank 1 along the vertical direction, and a limiting ring 74 is provided below the supporting plate 73, and the limiting ring 74 is fixedly connected to the inner wall of the storage tank 1.

[0044] By setting the above structure, when the screw 52 rotates in the forward direction, the lifting plate 71 can be driven to rise. At this time, the lifting plate 71 first compresses the second spring 72.

[0048] By setting the above structure, air flow is input into the sealing cover 91 through the air inlet pipe 92, and the semicircular sealing block 94 is driven by the screw 52 to seal the inlet of any L-shaped ventilation pipe 95. The air flow inside the sealing cover 91 enters the other L-shaped ventilation pipe 95 and enters the storage tank 1 through the air holes on its surface to ventilate the rice. The ventilated air enters the L-shaped ventilation pipe 95 through the air holes on the L-shaped ventilation pipe 95 with the opening blocked, and is then discharged through the extension pipe 96 connected to the L-shaped ventilation pipe 95. Under the continuous rotation of the semicircular sealing block 94, the two L-shaped ventilation pipes 95 repeat the air intake and exhaust operations, thereby ensuring the uniformity of ventilation of the rice inside the storage tank 1.

[0050] The present invention also provides a method for using a rice storage and transportation device in rice production, which specifically comprises the following steps:

[0051] S1, in the storage state, paddy is added to the storage tank 1 through the feed hopper 2 until the storage tank 1 is full, and the feed hopper 2 is closed. After storage is completed, the drive motor 51 drives the screw 52 to repeat the forward and reverse rotation operations. In addition, air is input into the sealing cover 91 through the air inlet pipe 92. The semicircular sealing block 94 seals the inlet of any L-shaped ventilation pipe 95 under the drive of the screw 52. The airflow inside the sealing cover 91 enters the other L-shaped ventilation pipe 95 and enters the storage tank 1 through the air holes on its surface to ventilate the paddy. The ventilated air enters the L-shaped ventilation pipe 95 through the air holes on the L-shaped ventilation pipe 95 with the opening blocked, and is then discharged through the extension pipe 96 connected to the L-shaped ventilation pipe 95. Under the continuous rotation of the semicircular sealing block 94, the two L-shaped ventilation pipes 95 repeat the air intake and exhaust operations;

[0052] S2. In the discharging state, the hydraulic cylinder 44 drives its output shaft to extend and retract according to actual needs, and then the hydraulic cylinder 44 drives the discharging pipe 42 and the lifting adjustment plate 41 to rise and fall through the first fixed collar 43 to adjust the discharging height of the discharging pipe 42. When the lifting adjustment plate 41 moves, the second driving mechanism 6 is driven to rise and fall as a whole on the outside of the screw 52 through the lifting cross bar 45 and the first connecting collar 46. Then, the stop valve on the discharging pipe 42 is opened, and the rice located in the upper part of the inner cavity of the storage tank 1 is discharged through the discharging pipe 42;

[0053] S3. After the rice located in the upper part of the inner cavity of the storage tank 1 is output, the drive motor 51 is started. After the drive motor 51 is started, the screw 52 is driven to rotate continuously. When the screw 52 rotates, the lifting plate 71 is driven to rise continuously. When the lifting plate 71 rises, it first compresses the second spring 72, and then drives the supporting plate 73 to rise synchronously.

At this time, the horizontal height of the arc-shaped pushing plate 82 is higher than the horizontal height of the L-shaped ventilation pipe 95. At this time, the screw 52 drives the lifting ring 62 to rotate through the lifting shaft 61, and the lifting ring 62 drives the rotating seat 81 to rotate synchronously through the two positioning pins 63. The rotating seat 81 drives multiple arc-shaped pushing plates 82 to rotate, thereby pushing a small amount of rice remaining on the top of the carrying plate 73;

[0055] S5. When the lifting distance of the lifting plate 71 reaches the second threshold, the supporting plate 73 moves to below the inlet of the discharge pipe 42. At this time, the rice on the top of the supporting plate 73 is pushed by multiple arc-shaped pushing plates 82 and is all discharged by the discharge pipe 42.

When the lifting distance of the lifting plate reaches the first threshold, the two positioning pins are respectively inserted into the two slots on the top of the rotating seat. At this time, the horizontal height of the arc-shaped pushing plate is higher than the horizontal height of the L-shaped ventilation pipe. At this time, the screw drives the lifting ring to rotate through the lifting shaft, and the lifting ring drives the rotating seat to rotate synchronously through the two positioning pins. The rotating seat drives multiple arc-shaped pushing plates to rotate, thereby pushing the small amount of rice remaining on the top of the carrying plate; S5. When the lifting distance of the lifting plate reaches the second threshold, the supporting plate moves to below the inlet of the discharge pipe. At this time, the rice on the top of the supporting plate is pushed by multiple arc-shaped pushing plates and is all discharged from the discharge pipe.
