Description

Technical Field

[0001] This invention relates to the field of granular grain collection equipment, and in particular to an automatic grain collection vehicle for potholed roads. Background Technology

[0002] After harvesting grain crops such as wheat, corn, and peanuts, small-scale farmers spread them out in the open to dry. After drying, they are manually collected, bagged, and stored. This process is time-consuming, labor-intensive, and inefficient. Current grain collection equipment is generally suitable for large-scale bulk grain collection, but shallow-layer grains or residual grains in depressions still require manual processing and secondary cleaning. Furthermore, existing equipment cannot automatically bag or change bags, requiring continuous operator intervention. Therefore, the entire grain collection process still requires a significant amount of manual labor, resulting in high operating costs and poor collection efficiency. Summary of the Invention

[0003] This invention aims to solve the above problems and provides an automatic grain collection vehicle that can be used on potholed roads. The technical solution adopted is as follows:

[0004] An automatic grain collecting vehicle for potholed roads includes a grain collecting mechanism, a surplus grain cleaning mechanism, a walking mechanism, a transport mechanism, and a bagging mechanism. The walking mechanism includes a base plate and tracks. The transport mechanism is mounted on the base plate. The bagging mechanism is positioned above the transport mechanism, driving a bag for holding grain to move and controlling the opening and closing of the bag. The bottom of the bag rests on the transport mechanism, and the transport mechanism moves in the same direction as the bag. The grain collecting mechanism is positioned in front of the walking mechanism in the direction of movement. The grain collecting mechanism includes a grain collecting shell, spiral blades, and a conveyor belt. The system includes a housing, a conveyor belt, and a grain outlet. The grain receiving housing, the conveyor housing, and the grain outlet are connected. The grain outlet is located above the opening of the bag. The conveyor belt is located inside the conveyor housing. Spiral blades are rotatably mounted inside the grain receiving housing and convey the grain to the conveyor belt. A residual grain cleaning mechanism is provided between the grain receiving mechanism and the traveling mechanism. The residual grain cleaning mechanism includes a cleaning mechanism housing and a cleaning unit. The cleaning mechanism housing is connected to the conveyor housing. The cleaning unit is rotatably mounted on the cleaning mechanism housing, and the rotation tangent at the bottom of the cleaning unit faces the direction of the conveyor housing.

[0005] Based on the above scheme, the cleaning unit includes a drive crank and a movable block. Both the drive crank and the movable block are Y-shaped structures, and each branch is evenly distributed circumferentially about its own axis. There are two drive cranks and two movable blocks. The drive cranks are located on the opposite outer side of the movable blocks. A first connecting rod is hinged between the corresponding branch ends of the drive cranks and the movable blocks, and a second connecting rod is hinged between the corresponding branch ends of the two movable blocks. The axes of the two drive cranks are collinear, and the axes of the two movable blocks are parallel but not collinear. The axes of the two movable blocks are parallel to but not collinear with the axes of the drive cranks. Springs are connected to the ends of each branch of the movable blocks. The springs are arranged radially along the movable blocks. The cleaning unit also includes an arc plate. There are three arc plates connected to each movable block. One end of each arc plate is connected to the end of a branch of the movable block, and the other end is connected to the free end of the spring on the adjacent branch of the movable block. The arc opening of the arc plate faces one side of the movable block, and a brush is connected to the side of the arc plate away from the movable block.

[0006] Preferably, the top of the bag is connected to a sealing clip, which is a parallelogram structure with each side hinged sequentially. The bagging mechanism includes two bag feeding guides, each with a slider slidably mounted on it. The opposite ends of the sealing clip are detachably mounted on the slider and move with it. The bag feeding guides include a first parallel section, a contraction section, an expansion section, and a second parallel section arranged sequentially along the direction of bag movement. In the first parallel section, the distance between the bag feeding guides is constant and is 0.8 to 0.9 times the maximum distance between the opposite ends of the sealing clip. In the second parallel section, the distance between the bag feeding guides is the maximum distance between the opposite ends of the sealing clip. The distance between the bag feeding guides gradually decreases in the contraction section and gradually increases in the expansion section. The grain outlet is located above the connection between the contraction section and the expansion section.

[0007] Based on the above scheme, a synchronous belt is wound around the bag feeding guide rail. The synchronous belt is driven and moved by a synchronous belt motor. A friction plate is set on the slider facing the synchronous belt. The friction plate is in close contact with the synchronous belt, and the synchronous belt drives the slider to move.

[0008] Based on the above scheme, the slider includes a sliding frame, which is U-shaped and surrounds the lower fixing plate of the bag feeding guide rail and the inner and outer sides of the timing belt. Friction plates are fixedly connected to the inner side of the sliding frame. A first pulley and a second pulley are provided inside the U-shaped opening of the sliding frame. The first pulley and the second pulley are respectively provided on the inner and outer sides of the timing belt and roll on the upper surface of the lower fixing plate of the bag feeding guide rail. A third pulley is provided at the top of the sliding frame. The third pulley is horizontally arranged and rolls on the inner surface of the upper fixing plate of the bag feeding guide rail.

[0009] Based on the above scheme, a sliding groove is provided on the bag feeding guide rail, and the sliding groove is located at the moving path of the first pulley, the second pulley and the third pulley.

[0010] Preferably, the synchronous belt includes a first synchronous belt and a second synchronous belt. The first synchronous belt is wound around the first parallel section, and the second synchronous belt is wound around the contraction section, the expansion section, and the second parallel section. The first synchronous belt connects to multiple bags. The transport mechanism is located below the second synchronous belt.

[0011] Preferably, the sealing clamp is provided with a buckle, the buckle including a locking block on one side of the sealing clamp and a locking ring hinged at the corresponding position on the other side of the sealing clamp. A stop bar is provided on the second parallel section. The stop bar is set in a horizontal direction. The height of the stop bar is lower than the lower edge of the locking ring in the open state and higher than the upper edge of the locking ring in the closed state. When the buckle passes the stop bar, the locking ring rotates downward and locks onto the locking block.

[0012] Preferably, the conveyor belt is provided with multiple baffles, which extend outward from the outer surface of the conveyor belt in a direction perpendicular to the conveyor belt, forming a grain conveying cavity between adjacent baffles; it also includes a dust removal mechanism, which includes a dust removal fan, an air inlet pipe and an air outlet pipe. The dust removal fan and the air inlet pipe are both provided on opposite sides of the conveyor housing. The air inlet pipe is provided with multiple air inlets, each corresponding to a different grain conveying cavity. The dust removal fan introduces air into the conveyor housing through the air inlet pipe. The air outlet pipe is provided on the upper side of the conveyor housing at the air inlet position. The air outlet pipe is connected to the inlet grain conveying cavity through multiple air outlets. The conveyor housing is provided with a filter screen at the air outlet position.

[0013] Preferably, there are multiple cleaning units, which are arranged perpendicular to the moving direction of the walking mechanism, and the multiple cleaning units are symmetrically distributed about the conveyor housing.

[0014] The beneficial effects of this invention are as follows: A residual grain cleaning mechanism is added to the rear of the grain collecting mechanism. Each cleaning unit continuously drives the brush to rotate via an eccentrically positioned movable block, clearing the residual grain from the pit and conveying it to the grain collecting mechanism for unified collection. This effectively ensures that grain particles on the ground are collected in one go, eliminating the need for secondary manual cleaning, thus effectively reducing labor costs and improving grain collecting efficiency and quality. Furthermore, the use of a bagging mechanism with variable guide rail spacing allows the bags containing grain to automatically open, close, and seal during movement. This allows for the simultaneous use of multiple bags, significantly reducing manual intervention and labor costs during the grain collecting process. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] In the description of this invention, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figure 1 and Figure 2 As shown, an automatic grain collection vehicle for pothole roads includes a grain collection mechanism, a surplus grain cleaning mechanism, a walking mechanism, a transport mechanism, and a bagging mechanism.

[0027] The walking mechanism includes a base plate 41 and a walking track 42. The walking track 42 is driven and rotated by a walking motor 43, which in turn drives the base plate 41 to move.

[0028] The transport mechanism is mounted on the base plate 41, and the bagging mechanism is positioned above it. The bagging mechanism moves the bag 611 used to hold the grain and controls the opening and closing of the bag 611. The bottom of the bag 611 rests on the transport mechanism, and the transport mechanism and the bag 611 move in the same direction. The transport mechanism includes guide rollers 51, a transport timing belt 52, and a transport motor 53. Multiple guide rollers 51 are arranged in parallel. The transport timing belt 52 is wound around the guide rollers 51. The transport motor 53 drives the transport timing belt 52 to rotate via gears. The guide rollers 51 support the transport timing belt 52. A lower bag buffer plate 54 is provided at the transport direction end of the upper surface of the transport timing belt 52.

[0029] like Figure 7 As shown, a sealing clip 612 is connected to the top of the bag body 611. The sealing clip 612 has a parallelogram structure, and its sides are hinged sequentially. By controlling the angle between adjacent sides of the sealing clip 612, the opening and closing of the bag body 611 can be controlled. Figure 6As shown, the bagging mechanism includes two bag feeding guide rails 62. Sliding sliders 67 are slidably mounted on the bag feeding guide rails 62. The opposite ends of the sealing clamps 612 are detachably mounted on the sliding sliders 67 and move with them. The bag feeding guide rail 62, along the moving direction of the bag body 611, includes a first parallel section 621, a contraction section 622, an expansion section 623, and a second parallel section 624 arranged sequentially. At the first parallel section 621, the distance between the bag feeding guide rails 62 is constant and 0.8 to 0.9 times the maximum distance between the two ends of the sealing clips 612. At the second parallel section 624, the distance between the bag feeding guide rails 62 is the maximum distance between the two ends of the sealing clips 612. The distance between the bag feeding guide rails 62 gradually shortens at the contraction section 622 and gradually increases at the expansion section 623. The bag body 611 is pre-opened at the first parallel section 621. During its movement at the contraction section 622, the two ends of the sealing clips 612 move closer together, causing the opening of the bag body 611 to gradually expand, reaching its maximum at the end of the contraction section 622, facilitating grain collection. The bag body 611 pauses and collects grain at the connection between the contraction section 622 and the expansion section 623. A pressure sensor is installed on the transport mechanism, located below the end of the contraction section 622, to detect the weight or pressure of the bag 611, thereby determining whether the bag has finished receiving grain. After receiving the grain, the bag 611 continues to move into the expansion section 623, causing the opening of the bag 611 to gradually close until it is completely closed at the second parallel section 624. Through the above structure and process, the automatic opening and closing of the bag 611 can be completed. The connection points of the first parallel section 621, the contraction section 622, the expansion section 623, and the second parallel section 624 are all smooth transitions. Preferably, a buckle 613 is provided on the sealing clamp 612. The buckle 613 includes a locking block on one side of the sealing clamp 612 and a locking ring hinged at the corresponding position on the other side of the sealing clamp 612. A stop bar 625 is provided on the second parallel section 624. The stop bar 625 is set in a horizontal direction. The height of the stop bar 625 is lower than the lower edge of the locking ring in the open state and higher than the upper edge of the locking ring in the closed state. When the buckle 613 passes the stop bar 625, the locking ring rotates downward and locks onto the locking block, thereby completing the sealing on the basis of the closed bag body 611 and preventing the grain in the bag from leaking.

[0030] Preferably, the synchronous belt 63 includes a first synchronous belt and a second synchronous belt. The first synchronous belt is wound around the first parallel section 621, and the second synchronous belt is wound around the contraction section 622, the expansion section 623, and the second parallel section 624. Multiple bags 611 are connected to the first synchronous belt. The transport mechanism is located below the second synchronous belt. Multiple bags 611 are hung on the first synchronous belt for bagging and storage. After the bags 611 on the second synchronous belt are filled, the first synchronous belt moves, carrying the empty bags to the contact position with the second synchronous belt, whereupon the second synchronous belt continues to transport the empty bags.

[0031] Specifically, a synchronous belt 63 is wound around the bag feeding guide 62. The synchronous belt 63 is driven and moved by a synchronous belt motor 64. A friction plate 672 is provided on the side of the slider 67 facing the synchronous belt 63. The friction plate 672 is in close contact with the synchronous belt 63, and the synchronous belt 63 drives the slider 67 to move through friction. Multiple auxiliary rollers 65 are provided on the bag feeding guide 62. The auxiliary rollers 65 are located inside the synchronous belt 63 to reduce the friction during the synchronous belt 63's transmission process and to support and limit the synchronous belt 63. Multiple limiting posts 66 are also provided at the shrinking section 622 and the unfolding section 623. The limiting posts 66 are located at the upper and lower ends of the synchronous belt 63 to limit the position of the synchronous belt 63.

[0032] The slider 67 includes a sliding frame 671, which is U-shaped and surrounds the lower fixing plate of the bag feeding guide rail 62 and the inner and outer sides of the synchronous belt 63. Friction plates 672 are fixedly connected to the inner side of the sliding frame 671. A first pulley 673 and a second pulley 674 are arranged inside the U-shaped opening of the sliding frame 671. The first pulley 673 and the second pulley 674 are respectively arranged on the inner and outer sides of the synchronous belt 63 and roll on the upper surface of the lower fixing plate of the bag feeding guide rail 62. A third pulley 675 is arranged horizontally at the top of the sliding frame 671 and rolls on the inner surface of the upper fixing plate of the bag feeding guide rail 62. By using multiple pulleys in different directions, the slider 67 can move stably on the bag feeding guide rail 62 while effectively reducing the friction during the movement of the slider 67. The bag feeding guide rail 62 is provided with a sliding groove 626, which is located at the movement path of the first pulley 673, the second pulley 674, and the third pulley 675 to limit the movement trajectory of each pulley. A connecting post 676 is fixedly provided on the lower side of the sliding frame 671, and the sealing clamp 612 has connecting holes 614 at opposite ends. By passing the connecting post 676 through the connecting holes 614 and cooperating with bolts and other fasteners, the bag body 611 is connected.

[0033] The grain receiving mechanism is located in front of the traveling mechanism in the direction of movement. The grain receiving mechanism includes a grain receiving shell 11, a spiral blade 12, a conveyor shell 13, a conveyor belt 14, and a grain outlet 16. The grain outlet 16 is located above the connection between the contraction section 622 and the expansion section 623. The grain receiving shell 11, the conveyor shell 13, and the grain outlet 16 are connected. The grain outlet 16 is located above the opening of the bag body 611. The conveyor belt 14 is located inside the conveyor shell 13. The spiral blade 12 is located near the ground surface. The spiral blade 12 is rotatably mounted inside the grain receiving shell 11 and conveys the grain to the conveyor belt 14. The conveyor belt 14 then transfers the grain to the grain outlet 16 for bagging.

[0034] A residual grain cleaning mechanism is provided between the grain receiving mechanism and the traveling mechanism. The residual grain cleaning mechanism includes a cleaning mechanism housing 21 and a cleaning unit 22. The cleaning mechanism housing 21 is connected to the conveying housing 13. The cleaning unit 22 is rotatably mounted on the cleaning mechanism housing, and the rotation tangent at the bottom of the cleaning unit 22 faces the conveying housing 13, thereby transferring the grain into the conveying housing 13 and conveying it by the conveyor belt 14.

[0035] like Figure 3 and Figure 4 As shown, the cleaning unit 22 includes a drive crank 221 and a movable block 223. Both the drive crank 221 and the movable block 223 are Y-shaped structures, and each branch is evenly distributed circumferentially about its respective axis. There are two drive cranks 221 and two movable blocks 223. The drive cranks 221 are located on the opposite outer side of the movable blocks 223. A first connecting rod 222 is hinged between the corresponding branch ends of the drive cranks 221 and the movable blocks 223, and a second connecting rod 227 is hinged between the corresponding branch ends of the two movable blocks 223. The axes of the two drive cranks 221 are collinear, and the axes of the two movable blocks 223 are parallel but not collinear. The axes of the two movable blocks 223 are respectively aligned with... The axes of the drive handle 221 are parallel but not collinear; the ends of each branch of the movable block 223 are connected to springs 224, which are arranged radially along the movable block 223. The cleaning unit 22 also includes an arc plate 225. There are three arc plates 225 connected to each movable block 223. One end of each arc plate 225 is connected to the end of a branch of the movable block 223, and the other end is connected to the free end of the spring 224 on the adjacent branch of the movable block 223. The arc opening of the arc plate 225 faces the movable block 223. A brush 226 is connected to the side of the arc plate 225 away from the movable block 223. When the brush 226 rotates to the bottom, the end of the brush 226 is lower than the ground surface. Rotating the drive handle 221 on one side drives two movable blocks 223 to rotate, thereby sweeping and collecting residual grain particles on the ground and in pits using brushes 226. A spring 224 adjusts the radial position of the brushes 226, allowing them to adapt to pits of varying depths. Multiple cleaning units 22 are arranged perpendicular to the direction of movement of the walking mechanism, symmetrically distributed about the conveyor housing 13. This increases the collection area and improves collection efficiency, while multiple cleaning operations enhance collection quality.

[0036] like Figure 5As shown, multiple baffles 15 are provided on the conveyor belt 14. The baffles 15 extend outward from the outer surface of the conveyor belt 14 in a direction perpendicular to the conveyor belt 14, and a grain conveying chamber is formed between adjacent baffles 15. For preliminary cleaning of the collected grain, a dust removal mechanism is also included. The dust removal mechanism includes a dust removal fan 31, an inlet pipe 32, and an outlet pipe 34. The dust removal fan 31 and the inlet pipe 32 are both located on opposite sides of the conveyor housing 13. The inlet pipe 32 has multiple air inlets, each corresponding to a different grain conveying chamber. The dust removal fan 31 introduces air into the conveyor housing 13 through the inlet pipe 32. The outlet pipe 34 is located on the upper side of the conveyor housing 13 at the air inlet position and communicates with the inlet grain conveying chamber through multiple air outlets. A filter screen 33 is provided at the air outlet position of the conveyor housing 13. The dust removal fan 31 causes the dust in the grain conveying chamber to be discharged through the air outlet 34 along with the high-speed airflow. During the dust removal process, the grain particles are blocked by the filter screen 33, thus completing the dust removal and cleaning process.

[0037] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
