Grain clean-out turnover device

Abstract

The present application relates to the technical fields of grain cleaning, and discloses a grain cleaning and turnover device, which comprises a vehicle body, a pushing frame fixedly connected to the front end of the vehicle body, and a rolling cylinder rotatably connected to the inner wall of the pushing frame. When the piston block contacts the side wall of the slide rod, the slide rod drives the sliding plate I to slide along the inner wall of the through hole fixed plate I, so that the through hole of the through hole fixed plate I coincides with the through hole of the sliding plate I. The negative pressure in the pulling frame reaches the inside of the inclined collecting groove through the above-mentioned coinciding gap. With the continuous rotation of the rolling cylinder, the spring inclined rod at the bottom moves upward. At this time, the pressure applied to the outer wall of the spring inclined rod disappears, the spring II drives the L-shaped sliding plate to reset, and the bulk grain in the inclined collecting groove enters the inside of the flow-through port I along the inclined surface of the inner wall of the inclined collecting groove. Under the action of the negative pressure, the bulk grain enters the inside of the circular pipe, thereby effectively collecting the recessed position at the bottom of the ship cabin.

Description

Technical Field

[0001] This invention relates to the field of grain cleaning technology, specifically a grain cleaning and turning device. Background Technology

[0002] Grain ships in ports typically use unloaders or grab buckets to remove grain from their holds. However, neither unloaders nor grab buckets can completely remove all the grain from the holds, leaving some residue. In such cases, forklifts are used to pile up the remaining grain, which is then discharged outwards using grab buckets.

[0003] To ensure sufficient load-bearing capacity, the ship's interior is equipped with a steel beam structure. However, under the pressure of thousands of tons of grain, small indentations will appear in these steel beam structures. After the grab bucket completes the final grain transport process, some grain will remain in these indentations. Since the bottom of the loader's bucket is smooth, it is difficult to effectively remove the grain from these indentations, resulting in excessive grain residue at the bottom of the ship's hold. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a grain clearing and turning device, including a vehicle body, a push frame fixedly connected to the front end of the vehicle body, a rolling cylinder rotatably connected to the inner wall of the push frame, an electric telescopic rod fixedly connected to the side wall of the push frame, a sliding frame fixedly connected to the end of the electric telescopic rod away from the push frame, and a rotating tube fixedly connected to the inner wall of the through hole of the side wall of the push frame.

[0005] The collecting mechanism is fixedly connected to the inner wall of the rolling drum and is used to change the air pressure state inside the rolling drum.

[0006] The pressure mechanism is fixedly connected to the inner wall of the rolling drum and is used to absorb the loose grain scattered inside the ship's hold.

[0007] The discharge mechanism is fixedly connected to the inner wall of the rotating drum to prevent the loose grain entering the rotating drum from flowing back due to the rotation of the rotating drum.

[0008] When it is necessary to collect loose grain inside the ship's hold, the driver first uses an electric telescopic rod to drive the sliding frame to close the side wall of the rotating tube, and then drives the vehicle to move the rolling drum towards the location where there is loose grain.

[0009] Preferably, the collection institutions include:

[0010] The pressure-bearing component is fixedly connected to the inner wall of the push frame via a drive component;

[0011] The driving component includes a toothed ring fixedly connected to the inner wall of the push frame, nine round tubes fixedly connected to the inner wall of the rolling cylinder, a toothed rod rotatably connected to the inner wall of the nine round tubes, a double-threaded rod fixedly connected to the side wall of the toothed rod, and a piston block meshing with the outer wall of the double-threaded rod.

[0012] The collection component is slidably connected to the side wall of the round tube by a slide rod, and a tensioning bracket is fixedly connected to the side wall of the slide rod;

[0013] As the vehicle moves forward, the rolling drum will roll, carrying nine toothed rods that roll along the outer wall of the toothed ring. The rolling toothed rods drive the piston block to reciprocate along the inner wall of the circular tube.

[0014] Preferably, the pressure mechanism includes:

[0015] The adsorption component is fixedly connected to the inner wall of the rotating drum via a collecting element.

[0016] The collecting component includes an inclined collecting groove formed on the inner wall of the rolling drum, an L-shaped sliding plate slidably connected to the inner wall of the inclined collecting groove, a spring inclined rod slidably connected to the outer wall of the rolling drum, and a round rod rotatably connected to the inner wall of the L-shaped sliding plate.

[0017] The opening and closing assembly is fixedly connected to the inner wall of the rotating cylinder via a collection component;

[0018] The collection component includes a flow port one opened on the inner wall of the inclined collection trough, a flow port two opened on the inner wall of the rolling cylinder, and a through hole fixing plate one fixedly connected to the inner wall of the flow port one.

[0019] During the rotation of the drum, the spring-loaded inclined rod at the bottom will be compressed and move. The spring-loaded inclined rod forces the round rod to slide along the inner wall of the inclined collection trough through the inclined surface, so that the bulk grain enters the inner wall of the inclined collection trough through the gap between the inclined collection trough and the L-shaped sliding plate.

[0020] Preferably, the discharge mechanism includes:

[0021] The flow component is fixedly connected inside the flow port two via a closure;

[0022] The closure includes a through-hole fixing plate two fixedly connected to the inner wall of the flow port two, a sliding plate two slidably connected to the inner wall of the through-hole fixing plate two, and an L-shaped pressure rod fixedly connected to the top of the sliding plate two.

[0023] A closing component is fixedly connected to the inner wall of the pressure-bearing component via a sealing element;

[0024] When the piston block moves toward the sliding frame, the piston block will squeeze the L-shaped pressure rod, forcing the L-shaped pressure rod to drive the sliding plate two to slide along the inner wall of the through hole fixing plate two, and at this time the through hole of the sliding plate two will coincide with the through hole of the through hole fixing plate two.

[0025] Preferably, the pressure-bearing component includes a bell-shaped tube fixedly connected to the inner wall of the rolling cylinder, the outer wall of the toothed rod meshing with the outer wall of the toothed ring, and the outer wall of the piston block slidingly connected to the inner wall of the round tube.

[0026] The piston block has rubber rings fixedly connected to its interior and outer wall to ensure the sealing of the connection between the piston block and the round tube.

[0027] Preferably, the collecting assembly includes a spring that is fixedly connected to the side wall of the slide bar, and the other end of the spring is used for fixed connection to the inner wall of the round tube;

[0028] When the piston block slides along the inner wall of the circular tube, the side wall of the piston block will contact the side wall of the slide rod, forcing the slide rod to drive the pulling frame to move outward.

[0029] Preferably, the adsorption assembly includes a second spring fixedly connected to the side wall of the L-shaped sliding plate, and the end of the second spring away from the L-shaped sliding plate is fixedly connected to the inner wall of the inclined collection groove.

[0030] When the L-shaped sliding plate moves laterally along the inner wall of the inclined collection groove, the pressure applied by the second spring will cause it to contract and accumulate potential energy.

[0031] Preferably, the opening and closing assembly includes a sliding plate slidably connected to the inner wall of the through-hole fixing plate, and the end of the pull bracket away from the slide rod is fixedly connected to the inner wall of the through-hole fixing plate.

[0032] When the piston block moves toward the slide rod, since the opening and closing assembly and the flow assembly are in a closed state, a negative pressure will be generated inside the round tube as the piston block moves. When the piston block contacts the side wall of the slide rod, the slide rod drives the sliding plate one to slide along the inner wall of the through hole fixing plate one through the pulling frame, so that the through hole of the through hole fixing plate one coincides with the through hole of the sliding plate one, so that the negative pressure inside the pulling frame reaches the inside of the inclined collection trough, and draws the grain inside the inclined collection trough into the inside of the round tube.

[0033] Preferably, the flow assembly includes a spring three fixedly connected to the side wall of the sliding plate two, and the end of the spring three away from the sliding plate two is fixedly connected to the inner wall of the through hole fixing plate two;

[0034] When the second sliding plate slides, the third spring will be compressed and store potential energy. After the piston block moves away from the L-shaped pressure rod, the third spring will drive the second sliding plate to reset.

[0035] Preferably, the closing assembly includes an outflow groove formed on the side wall of the horn tube, a fixed square rod is fixedly connected to the inner wall of the outflow groove, a rotating arc plate is rotatably connected to the inner wall of the fixed square rod, and a torsion spring is fixedly connected to the side wall of the rotating arc plate.

[0036] As the rolling drum rotates, it drives the trumpet tube to rotate in the same direction. When the rotating arc plate is in the upper position, it will rotate due to the high-pressure air jet from the top. When it rotates downward, the rotating arc plate will gradually close, restricting the flow of the bulk grain.

[0037] The present invention has the following beneficial effects:

[0038] (1) This invention addresses the problem of difficulty in collecting loose grain in recessed areas by providing a collection mechanism inside the device. When the piston block contacts the side wall of the sliding rod, the sliding rod drives the sliding plate one to slide along the inner wall of the through hole fixing plate one through the pulling frame, so that the through hole of the through hole fixing plate one coincides with the through hole of the sliding plate one. The negative pressure inside the pulling frame reaches the inside of the inclined collection trough through the above-mentioned overlapping gap. At this time, the inclined collection trough will adsorb the loose grain at the bottom of the cabin and send it to the inside of the inclined collection trough. As the rolling drum continues to rotate, the spring inclined rod at the bottom will move upward. At this time, the pressure applied to the outer wall of the spring inclined rod disappears, and the spring two will drive the L-shaped sliding plate to reset. The loose grain inside the inclined collection trough will enter the inside of the flow port one along the inclined surface of the inner wall of the inclined collection trough, and under the drive of the negative pressure, it will enter the inside of the round tube. Through the application of the above components, effective collection of the recessed area at the bottom of the cabin is achieved.

[0039] (2) This invention utilizes the reciprocating movement of the piston block and sets up a flow component inside the equipment. After the equipment completes the collection of the loose grain at the bottom, the piston block will move towards the sliding frame. After the sliding rod loses the compression of the piston block, the through hole fixing plate one and the sliding plate one will be in a closed state, and the flow component will also be in a closed state. When the piston block moves towards the sliding frame, it will compress the gas inside the round tube, making the gas inside the round tube form a high pressure state. When the round tube reaches the top, the piston block will compress the L-shaped pressure rod, forcing the L-shaped pressure rod to drive the sliding plate two to slide along the inner wall of the through hole fixing plate two, and forcing the through hole of the sliding plate two to coincide with the through hole of the through hole fixing plate two. At this time, the high pressure gas inside the round tube carries the loose grain quickly through the above-mentioned overlapping position and enters the inside of the trumpet tube. Through the application of the above component, too many impurities are avoided inside the round tube, which may cause blockage inside the equipment.

[0040] (3) The present invention utilizes the characteristics of the above-mentioned rotating drum to set up a closing component inside the equipment. As the rotating drum rotates, the rotating drum will drive the trumpet tube to rotate in the same direction. When the rotating arc plate is in the upper position, the rotating arc plate will rotate due to the high pressure jet at the top. When rotating downward, the rotating arc plate will gradually close, restricting the flow of loose grain and preventing the loose grain from returning to the inside of the round tube through the flow port 2, which would affect the collection efficiency of the equipment.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1, please refer to Figures 1-8 The present invention is a grain clearing and turning device, including a vehicle body 13, a push frame 14 fixedly connected to the front end of the vehicle body 13, a rolling cylinder 15 rotatably connected to the inner wall of the push frame 14, an electric telescopic rod 16 fixedly connected to the side wall of the push frame 14, a sliding frame 17 fixedly connected to the end of the electric telescopic rod 16 away from the push frame 14, and a rotating tube 18 fixedly connected to the inner wall of the through hole on the side wall of the push frame 14.

[0058] The collecting mechanism 1 is fixedly connected to the inner wall of the rolling drum 15 and is used to change the air pressure state inside the rolling drum 15.

[0059] Pressure mechanism 2 is fixedly connected to the inner wall of the rolling drum 15 and is used to absorb the loose grain scattered inside the ship's hold.

[0060] The discharge mechanism 3 is fixedly connected to the inner wall of the rolling drum 15 to prevent the loose grain entering the rolling drum 15 from flowing back due to the rotation of the rolling drum 15.

[0061] When it is necessary to collect loose grain inside the ship's hold, the driver first uses the electric telescopic rod 16 to drive the sliding frame 17 to close the side wall of the rotating tube 18, and then drives the vehicle body 13 to move the rolling drum 15 to the location where there is loose grain.

[0062] Collection agency 1 includes:

[0063] The pressure-bearing component 11 is fixedly connected to the inner wall of the push frame 14 via a drive component;

[0064] The driving component includes a toothed ring 111 fixedly connected to the inner wall of the push frame 14, nine round tubes 112 fixedly connected to the inner wall of the rolling cylinder 15, a toothed rod 113 rotatably connected to the inner wall of the nine round tubes 112, a bidirectional threaded rod 114 fixedly connected to the side wall of the toothed rod 113, and a piston block 115 meshing with the outer wall of the bidirectional threaded rod 114.

[0065] The collecting component 12 is slidably connected to the slide rod 121 on the side wall of the round tube 112, and the side wall of the slide rod 121 is fixedly connected to the pull frame 122.

[0066] As the vehicle body 13 moves forward, the rolling drum 15 will roll, carrying nine toothed rods 113 that roll along the outer wall of the toothed ring 111. The rolling toothed rods 113 drive the piston block 115 to reciprocate along the inner wall of the circular tube 112. Figure 4 As shown, when the circular tube 112 is at its highest position, the bidirectional threaded rod 114 drives the piston block 115 to the rightmost position, and when the circular tube 112 reaches the bottom, it will drive the piston block 115 to position T.

[0067] Pressure mechanism 2 includes:

[0068] Adsorption component 21 is fixedly connected to the inner wall of the rolling drum 15 via a collection component.

[0069] The collecting component includes an inclined collecting groove 211 formed on the inner wall of the rolling drum 15, an L-shaped sliding plate 212 slidably connected to the inner wall of the inclined collecting groove 211, a spring inclined rod 213 slidably connected to the outer wall of the rolling drum 15, and a round rod 214 rotatably connected to the inner wall of the L-shaped sliding plate 212.

[0070] The opening and closing component 22 is fixedly connected to the inner wall of the rolling cylinder 15 via the collecting component;

[0071] The collection component includes a flow port 221 opened on the inner wall of the inclined collection trough 211, a flow port 222 opened on the inner wall of the rolling cylinder 15, and a through hole fixing plate 223 fixedly connected to the inner wall of the flow port 221.

[0072] When the piston block 115 moves toward the slide rod 121, since the opening and closing assembly 22 and the flow assembly 31 are in a closed state, a negative pressure will be generated inside the circular tube 112 as the piston block 115 moves. At this time, the spring inclined rod 213 at the bottom of the rolling cylinder 15 will contact the bottom of the cabin, and the spring inclined rod 213 will be compressed and move. The spring inclined rod 213 forces the circular rod 214 to drive the L-shaped sliding plate 212 to slide along the inner wall of the inclined collection groove 211 through the inclined surface, presenting a shape as shown in the figure. Figure 8 The status of G in China.

[0073] The material discharge mechanism 3 includes:

[0074] Flow component 31 is fixedly connected inside the flow port 222 by a closure;

[0075] The closure includes a through-hole fixing plate 311 fixedly connected to the inner wall of the flow port 222, a sliding plate 312 slidably connected to the inner wall of the through-hole fixing plate 311, and an L-shaped pressure rod 314 fixedly connected to the top of the sliding plate 312.

[0076] Closure component 32 is fixedly connected to the inner wall of pressure-bearing component 11 by a sealing member;

[0077] When the piston block 115 moves toward the sliding frame 17, the piston block 115 will squeeze the L-shaped pressure rod 314, forcing the L-shaped pressure rod 314 to drive the sliding plate 312 to slide along the inner wall of the through hole fixing plate 311, and at this time the through hole of the sliding plate 312 will coincide with the through hole of the through hole fixing plate 311.

[0078] Example 2, please refer to Figures 2-12 The present invention is a grain clearing and turning device. Based on Example 1, the pressure-bearing component 11 includes a trumpet tube 116 fixedly connected to the inner wall of the rolling cylinder 15, the outer wall of the toothed rod 113 meshing with the outer wall of the toothed ring 111, and the outer wall of the piston block 115 slidingly connected to the inner wall of the round tube 112.

[0079] Among them, rubber rings are fixedly connected to the inside and the outer wall of the piston block 115 to ensure the sealing of the connection between the piston block 115 and the round tube 112.

[0080] At this time, when the piston block 115 contacts the side wall of the slide rod 121, the slide rod 121 drives the sliding plate 224 to slide along the inner wall of the through hole fixing plate 223 through the pulling frame 122, so that the through hole of the through hole fixing plate 223 coincides with the through hole of the sliding plate 224. The negative pressure inside the pulling frame 122 reaches the inside of the inclined collection trough 211 through the above-mentioned overlapping gap. At this time, the inclined collection trough 211 will absorb the loose grain at the bottom of the cabin and send it into the inside of the inclined collection trough 211, and with the rolling As the rotating cylinder 15 continues to rotate, the spring inclined rod 213 at the bottom will move upward. At this time, the pressure applied to the outer wall of the spring inclined rod 213 will disappear, and the spring 215 will drive the L-shaped sliding plate 212 to reset. The loose grain inside the inclined collection trough 211 will enter the interior of the flow port 221 along the inclined surface of the inner wall of the inclined collection trough 211, and under the drive of negative pressure, it will enter the interior of the circular tube 112. Through the application of the above components, effective collection of the recessed position at the bottom of the cabin can be achieved.

[0081] The collecting assembly 12 includes a spring 123 fixedly connected to the side wall of the slide bar 121, and the other end of the spring 123 is used for fixed connection to the inner wall of the round tube 112.

[0082] When the piston block 115 slides along the inner wall of the circular tube 112, the side wall of the piston block 115 will contact the side wall of the slide rod 121, and force the slide rod 121 to drive the pulling frame 122 to move outward.

[0083] Taking advantage of the reciprocating movement of the piston block 115, a flow assembly 31 is installed inside the equipment. After the equipment completes the collection of loose grain at the bottom, the piston block 115 will move towards the sliding frame 17. After the slide rod 121 loses the compression of the piston block 115, the through hole fixing plate 223 and the sliding plate 224 will be in a closed state, and the flow assembly 31 will also be in a closed state. At this time, when the piston block 115 moves towards the sliding frame 17, it will compress the gas inside the circular tube 112, causing the gas inside the circular tube 112 to form a high pressure state. When the circular tube 112 reaches its top, the piston block 115 will squeeze the L-shaped pressure rod 314, forcing the L-shaped pressure rod 314 to drive the sliding plate 312 to slide along the inner wall of the through hole fixing plate 311, and forcing the through hole of the sliding plate 312 to coincide with the through hole of the through hole fixing plate 311. At this time, the high-pressure gas inside the circular tube 112 carries the bulk grain through the above-mentioned overlapping position and enters the interior of the trumpet tube 116. Through the application of the above components, excessive impurities are avoided inside the circular tube 112, which may cause blockage inside the equipment.

[0084] The adsorption assembly 21 includes a second spring 215 fixedly connected to the side wall of the L-shaped sliding plate 212, and one end of the second spring 215 away from the L-shaped sliding plate 212 is fixedly connected to the inner wall of the inclined collection groove 211.

[0085] When the L-shaped sliding plate 212 moves laterally along the inner wall of the inclined collection groove 211, the spring 215 will contract and accumulate potential energy when it is pressed.

[0086] As the amount of loose grain collected inside the horn tube 116 increases, the driver's vehicle body 13 drives the equipment to the collection area, and then the power supply of the electric telescopic rod 16 is turned on, causing the electric telescopic rod 16 to drive the sliding frame 17 to extend outward. The loose grain inside the horn tube 116 will fall into the collection area through the gap between the sliding frame 17 and the rotating tube 18.

[0087] The opening and closing assembly 22 includes a sliding plate 224 that is slidably connected to the inner wall of the through hole fixing plate 223, and the end of the pull bracket 122 away from the slide rod 121 is fixedly connected to the inner wall of the through hole fixing plate 223.

[0088] When the piston block 115 moves toward the slide rod 121, since the opening and closing component 22 and the flow component 31 are in a closed state, the inside of the round tube 112 will generate negative pressure as the piston block 115 moves. When the piston block 115 contacts the side wall of the slide rod 121, the slide rod 121 drives the sliding plate 224 to slide along the inner wall of the through hole fixing plate 223 through the pulling frame 122, so that the through hole of the through hole fixing plate 223 coincides with the through hole of the sliding plate 224, so that the negative pressure inside the pulling frame 122 reaches the inside of the inclined collection trough 211, and draws the grain inside the inclined collection trough 211 into the inside of the round tube 112.

[0089] The flow component 31 includes a spring 313 fixedly connected to the side wall of the sliding plate 312, and the end of the spring 313 away from the sliding plate 312 is fixedly connected to the inner wall of the through hole fixing plate 311.

[0090] When the sliding plate 2 312 slides, the spring 3 313 will accumulate potential energy under pressure, and after the piston block 115 moves away from the L-shaped pressure rod 314, the spring 3 313 will drive the sliding plate 2 312 to reset.

[0091] The closing assembly 32 includes an outflow groove 321 opened on the side wall of the horn tube 116, a fixed square rod 322 fixedly connected to the inner wall of the outflow groove 321, a rotating arc plate 323 rotatably connected to the inner wall of the fixed square rod 322, and a torsion spring 324 fixedly connected to the side wall of the rotating arc plate 323.

[0092] As the rolling drum 15 rotates, it drives the trumpet tube 116 to rotate in the same direction. When the rotating arc plate 323 is in the upper position, it will rotate due to the high-pressure jet from the top. When it rotates downward, the rotating arc plate 323 will gradually close, restricting the flow of loose grain and preventing it from returning to the inside of the circular tube 112 through the flow port 222, thus affecting the collection efficiency of the equipment.

[0093] One specific application of this embodiment is as follows: when it is necessary to collect loose grain inside the ship's hold, the driver first drives the sliding frame 17 to close the side wall of the rotating tube 18 through the electric telescopic rod 16, and then drives the vehicle body 13 to move the rolling drum 15 to the location where there is loose grain.

[0094] As the vehicle body 13 moves forward, the rolling drum 15 will roll. At this time, the rolling drum 15 will carry nine toothed rods 113, which will roll along the outer wall of the toothed ring 111. The rolling toothed rods 113 will drive the piston block 115 to reciprocate along the inner wall of the circular tube 112. Figure 4 As shown, when the circular tube 112 is at its highest position, the bidirectional threaded rod 114 drives the piston block 115 to the rightmost position, and when the circular tube 112 reaches the bottom, it will drive the piston block 115 to position T.

[0095] When the piston block 115 moves toward the slide rod 121, since the opening and closing assembly 22 and the flow assembly 31 are in a closed state, a negative pressure will be generated inside the circular tube 112 as the piston block 115 moves. At this time, the spring inclined rod 213 at the bottom of the rolling cylinder 15 will contact the bottom of the cabin. The spring inclined rod 213 will be compressed and move. The spring inclined rod 213 forces the circular rod 214 to drive the L-shaped sliding plate 212 to slide along the inner wall of the inclined collection groove 211 through the inclined surface, presenting a shape as shown in the figure. Figure 8 The status of G in the middle;

[0096] At this time, when the piston block 115 contacts the side wall of the slide rod 121, the slide rod 121 drives the sliding plate 224 to slide along the inner wall of the through hole fixing plate 223 through the pulling frame 122, so that the through hole of the through hole fixing plate 223 coincides with the through hole of the sliding plate 224. The negative pressure inside the pulling frame 122 reaches the inside of the inclined collection trough 211 through the above-mentioned overlapping gap. At this time, the inclined collection trough 211 will absorb the loose grain at the bottom of the cabin and send it into the inside of the inclined collection trough 211, and with the rolling As the rotating cylinder 15 continues to rotate, the spring inclined rod 213 at the bottom will move upward. At this time, the pressure applied to the outer wall of the spring inclined rod 213 will disappear, and the spring 215 will drive the L-shaped sliding plate 212 to reset. The loose grain inside the inclined collection trough 211 will enter the interior of the flow port 221 along the inclined surface of the inner wall of the inclined collection trough 211, and under the drive of negative pressure, it will enter the interior of the circular tube 112. Through the application of the above components, effective collection of the recessed position at the bottom of the cabin can be achieved.

[0097] Taking advantage of the reciprocating movement of the piston block 115, a flow assembly 31 is installed inside the equipment. After the equipment completes the collection of loose grain at the bottom, the piston block 115 will move towards the sliding frame 17. After the slide rod 121 loses the compression of the piston block 115, the through hole fixing plate 223 and the sliding plate 224 will be in a closed state, and the flow assembly 31 will also be in a closed state. At this time, when the piston block 115 moves towards the sliding frame 17, it will compress the gas inside the circular tube 112, causing the gas inside the circular tube 112 to form a high-pressure state. When the circular tube 112 reaches its top, the piston block 115 will squeeze the L-shaped pressure rod 314, forcing the L-shaped pressure rod 314 to drive the sliding plate 312 to slide along the inner wall of the through hole fixing plate 311, and forcing the through hole of the sliding plate 312 to coincide with the through hole of the through hole fixing plate 311. At this time, the high-pressure gas inside the circular tube 112 carries the bulk grain through the above-mentioned overlapping position and enters the interior of the trumpet tube 116. Through the application of the above components, too many impurities are left inside the circular tube 112, which may cause blockage inside the equipment.

[0098] Taking advantage of the rotation of the aforementioned rolling drum 15, a closing component 32 is installed inside the equipment. As the rolling drum 15 rotates, it drives the trumpet tube 116 to rotate in the same direction. When the rotating arc plate 323 is in the upper position, it will rotate due to the high-pressure air jet from the top. When rotating downwards, the rotating arc plate 323 will gradually close, restricting the flow of loose grain and preventing it from returning to the inside of the circular tube 112 through the flow port 222, thus affecting the collection efficiency of the equipment.

[0099] As the amount of loose grain collected inside the horn tube 116 increases, the driver uses the vehicle body 13 to drive the equipment to the collection area, and then turns on the power to the electric telescopic rod 16, causing the electric telescopic rod 16 to drive the sliding frame 17 to extend outward. The loose grain inside the horn tube 116 will fall into the collection area through the gap between the sliding frame 17 and the rotating tube 18.
