Technical Field
[0001] This utility model relates to the field of grain sampling, specifically a multi-stalk grain sampling device for sampling grain from grain trucks. Background Technology
[0002] my country is a major grain-producing country. As a fundamental natural resource, strategic economic resource, and public social resource for social development, grain is a very special product and commodity. Of the food people rely on for survival, 80% comes directly or indirectly from grain. As people's living standards have developed from a subsistence level to a moderately prosperous level, people's requirements for grain quality are no longer the previous concept of small quality, but a concept of large quality. Therefore, the issue of grain quality is receiving increasing attention.
[0003] In recent years, the form of grain logistics has undergone tremendous changes. During the grain procurement process, various types of grain transport vehicles often gather together. Currently, the commonly used sampling machinery can generally only sample small and medium-sized grain vehicles, resulting in a small sampling range, only one sampling point at a time, and low sampling efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a multi-bar grain sampling device for sampling grain trucks, which effectively solves the problem that the existing sampling machinery commonly used for large grain transport vehicles can only sample one point at a time, resulting in low sampling efficiency.
[0005] The technical solution of this utility model is as follows:
[0006] A multi-rod grain sampling device for grain truck sampling includes a rectangular frame with guide holes on two opposite faces. Two bidirectional threaded screws are provided on both sides of the frame, and symmetrically connected sliding blocks are provided on the bidirectional threaded screws. Positioning plates connected to the frame are provided at both ends of the bidirectional threaded screws. An externally powered motor is provided on the side of the positioning plates, and the output shaft of the motor is connected to the bidirectional threaded screw. A base is provided inside the frame, with guide shafts on both sides of the base. The guide shafts pass through the guide holes and are connected to the sliding blocks. Symmetrically mounted plates are provided on the sliding blocks, and sampling rods are provided on the mounting plates. A movable adjustment assembly is provided between the mounting plates and the base, and vertical sampling rods are symmetrically provided on the movable adjustment assembly.
[0007] Furthermore, a rotating gear is provided on the side of the frame away from the bidirectional threaded screw, and the vertical section of the frame side plate near the rotating gear is L-shaped. The horizontal section of the L-shaped part of the frame side plate is provided with spaced-apart matching slots, and the rotating gear and the matching slots cooperate with each other.
[0008] Furthermore, the sampling rod is vertically mounted on the mounting plate, and a cylinder assembly is provided at the top of the mounting plate. The cylinder assembly is connected to the top of the sampling rod to control the height change of the sampling rod.
[0009] Furthermore, the movable adjustment assembly includes a rotating wheel, a transmission belt, a linkage plate, a strip slide rail, and a sliding block. There are two rotating wheels, which are symmetrically arranged on the side of the base away from the sampling rod. The rotating wheels are movably connected to the base through a rotating shaft. The transmission belt is sleeved on the two rotating wheels. One of the rotating shafts is equipped with a motor with an external power supply.
[0010] Furthermore, there are two linkage plates, one end of which is connected to the mounting plate and the other end is symmetrically fixed to the transmission belt. The two linkage plates are respectively connected to the upper and lower layers of the transmission belt.
[0011] Furthermore, the strip rail is fixedly connected to the top of the base, the sliding block is symmetrically connected to the strip rail, and the sliding block is fixedly connected to the mounting plate.
[0012] Furthermore, the sampling rod includes a grain suction head and a rod body. The top of the grain suction head is provided with a mating ring, and the mating ring is provided with vertically arranged annular mating holes.
[0013] Furthermore, the bottom of the rod is provided with a retaining ring, and the bottom of the retaining ring is provided with a ring of plastic hooks. A sealing ring is provided between the grain suction head and the rod. After the grain suction head and the rod are engaged, the plastic hooks pass through the engagement hole and hook onto the bottom of the engagement ring.
[0014] The advantages of this utility model are:
[0015] 1. This utility model uses bidirectional threaded screws on both sides of the frame to drive two sliding blocks to move, thereby moving the base as well. The base is symmetrically equipped with sampling rods. With the cooperation of the cylinder assembly, the height of the sampling rods can be lowered. The number of sampling rods is set to multiple, so that multiple positions on the grain cart can be sucked at one time, which increases the sampling range at one time and improves the sampling efficiency.
[0016] 2. This utility model, by setting an adjustable distance component on the base, achieves rotation by rotating the transmission belt through the rotating wheel under the drive of the second motor. With the cooperation of the linkage plate, the distance between the two mounting plates can be changed, thereby adjusting the distance between the sampling rods. It can be adjusted for different widths of vehicle models to adapt to different vehicle widths, thus improving the flexibility of sampling.
[0017] 3. This utility model makes the head of the sampling rod detachable, and the number of grain suction heads is multiple. The grain suction heads can be quickly replaced by the combination of plastic hooks and matching rings. This allows for the replacement of different sampling rods for different types of grains, effectively avoiding the clogging of the grain suction heads. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] like Figures 1 to 6As shown, this utility model provides a multi-rod grain sampling device for grain truck sampling, which includes a rectangular frame 1, with guide holes 2 on two opposite surfaces of the frame 1, and bidirectional threaded screws 3 on both sides of the frame 1. The threads on the bidirectional threaded screws 3 are symmetrical. When the bidirectional threaded screws 3 rotate in one direction, the two sliding blocks 4 will move in opposite or opposite directions. There is no specific limitation on the use of bidirectional threaded screws 3, as long as the sliding blocks 18 can achieve the same opposite or opposite movement.
[0027] The bidirectional threaded screw 3 is symmetrically provided with movable sliding blocks 4, and both ends of the bidirectional threaded screw 3 are provided with positioning plates 5 connected to the frame 1. The positioning plates 5 are used to install the bidirectional threaded screw 3.
[0028] The side of the positioning plate 5 is equipped with an external power supply motor 6. The output shaft of the motor 6 is connected to the bidirectional threaded screw 3. The rotation of the bidirectional threaded screw 3 is achieved by the motor 6. In addition to electric means, it can also be replaced by hand crank or other means, as long as rotation can be achieved.
[0029] The frame 1 has a base 7 inside, and guide shafts 8 on both sides of the base 7. The guide shafts 8 pass through the guide holes 2 and are connected to the sliding block 4. The two ends of the guide shafts 8 are fixedly connected to the base 7 and the sliding block 4 respectively, so that when the sliding block 4 moves, the base 7 can be moved synchronously to adjust the position of the sampling rod 10.
[0030] The sliding block 4 is symmetrically mounted with a plate 9. The plate 9 is equipped with a sampling rod 10. The sampling rod 10 and the plate 9 can be fixed by screws, which can achieve a detachable connection. This allows the sampling rod 10 to be cleaned after sampling.
[0031] A movable adjustment assembly is provided between the mounting plate 9 and the base 7, and vertical sampling rods 10 are symmetrically provided on the movable adjustment assembly.
[0032] A rotating gear 11 is provided on the side of the frame 1 away from the bidirectional threaded screw 3. The rotating gear 11 is connected to the guide shaft 8. The vertical section of the side plate of the frame 1 near the rotating gear 11 is L-shaped. The horizontal section of the L-shaped side plate of the frame 1 is provided with spaced-apart mating grooves 12. The rotating gear 11 and the mating grooves 12 are mated with each other. The rotating gear 11 and the guide shaft 8 are rotatably connected. When the guide shaft 8 moves, the teeth on the rotating gear 11 will be embedded in the mating grooves 12, thereby ensuring the stability of the movement of the guide shaft 8.
[0033] The sampling rod 10 is vertically mounted on the mounting plate 9. The top of the mounting plate 9 is equipped with a cylinder assembly 13. The cylinder assembly 13 is connected to the top of the sampling rod 10 to control the height change of the sampling rod 10. The cylinder assembly 13 is connected to an external power source, so that the height of the sampling rod 10 can be changed, and samples can be taken from grain at different depths on the grain truck.
[0034] The adjustable distance assembly includes two rotating wheels 14, a transmission belt 15, a linkage plate 16, a strip slide rail 17, and a sliding block 18. The rotating wheels 14 are symmetrically arranged on the side of the base 7 away from the sampling rod 10. The rotating wheels 14 are movably connected to the base 7 via a rotating shaft 19. The rotating wheels 14 and the rotating shaft 19 are rotatably connected. The transmission belt 15 is sleeved on the two rotating wheels 14. When the rotating wheels 14 rotate, they will synchronously drive the transmission belt 15 to move. One of the rotating shafts 19 is equipped with a motor 20 with an external power supply. The connection between the aforementioned rotating wheels 14 and the transmission belt 15 can also be achieved by using a sprocket and rack mechanism.
[0035] There are two linkage plates 16. One end of each linkage plate 16 is connected to the mounting plate 9, and the other end is symmetrically fixed to the transmission belt 15. The two linkage plates 16 are respectively connected to the upper and lower layers of the transmission belt 15. By connecting the two linkage plates 16 to the upper and lower layers, the distance between the two sampling rods 10 on the same body 7 can be adjusted.
[0036] The strip slide rail 17 is fixedly connected to the top of the base 7, and the sliding block 18 is symmetrically connected to the strip slide rail 17. The sliding block 18 is fixedly connected to the mounting plate 9. Through the cooperation of the sliding block 18 and the strip slide rail 17, the position of the mounting plate 9 can be easily changed and the movement can be more flexible. However, the movement method does not include the one mentioned above. Other methods such as pulleys can also be used to move the mounting plate 9.
[0037] The sampling rod 10 includes a grain suction head 10-1 and a rod body 10-2. The top of the grain suction head 10-1 is provided with a mating ring 10-1-1. The mating ring 10-1-1 is provided with vertically arranged annular mating holes 10-1-2. The mating ring 10-1-1 is fixedly connected to the top of the grain suction head 10-1. The size of the mating hole 10-1-2 is smaller than the size of the plastic hook 10-2-2 in its normal state. Therefore, when the plastic hook 10-2-2 wants to be inserted into the mating hole 10-1-2, the shape of the plastic hook 10-2-2 needs to be bent to facilitate insertion into the mating hole 10-1-2 and spring back to achieve positioning.
[0038] The bottom of the rod 10-2 is provided with a retaining ring 10-2-1, and the bottom of the retaining ring 10-2-1 is provided with a ring of plastic hooks 10-2-2. The hooks are made of spring-loaded plastic material, which facilitates quick engagement with the mating hole 10-1-2, thereby enabling quick disassembly and replacement of the grain suction head 10-1.
[0039] A sealing ring 21 is provided between the grain suction head 10-1 and the rod body 10-2. The sealing ring 21 can improve the sealing between the grain suction head 10-1 and the rod body 10-2. After the grain suction head 10-1 and the rod body 10-2 are engaged, the plastic hook 10-2-2 passes through the mating hole 10-1-2 and hooks onto the bottom of the mating ring 10-1-1.
[0040] Detailed usage and function of the above embodiments:
[0041] The frame 1 can be installed above ground using support columns and other components. When the grain truck is sampling, it will drive under the frame 1. At this time, the motor 6 is started, which drives the bidirectional threaded screw 3 to rotate. The symmetrical sliding blocks 4 can move relative to each other or in opposite directions. The guide shaft 8 on the sliding block 4 moves in the guide hole 2. The other end of the guide shaft 8 is connected to the base 7, which drives the base 7 to move. The mounting plate 9 and the sampling rod 10 are connected to the base 7 through the movable adjustment assembly, which can adjust the spacing of the sampling rods 10 on both sides. When the appropriate spacing is adjusted, the sampling rod 10 will be lowered and extended into the grain truck under the drive of the cylinder assembly 13, so as to sample at multiple locations at the same time, increase the sampling area, and realize one-time multi-point sampling.
[0042] The second motor 20 is started, and the second motor 20 drives the rotating wheel 14 to rotate through the rotating shaft 19, which in turn moves the transmission belt 15. There are two layers of linkage plates 16 on the transmission belt 15. The other end of the linkage plate 16 is connected to the mounting plate 9. The sliding block 18 connected to the bottom of the mounting plate 9 is slidably connected to the strip rail 17, which can adjust the distance between the two sampling rods 10 on the same body 7, so that it can be adjusted for different widths of vehicle models and improve the flexibility of the device.
[0043] When sampling different types of grain, initially, the plastic hook 10-2-2 is hooked onto the bottom wall of the mating ring 10-1-1. The plastic hook 10-2-2 is bent inwards to disengage from the mating ring 10-1-1, allowing for the replacement of different types of grain suction heads 10-1. After replacement, the sealing ring 21 is placed between the two, and the plastic hook 10-2-2 is inserted back into the mating ring 10-1-1 to hook it, thus completing the replacement of the grain suction head 10-1.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
