Description

Technical Field

[0001] This invention relates to the field of grain suction and conveying technology, specifically an environmentally friendly grain unloading machine. Background Technology

[0002] Grain entering a warehouse generally involves four steps: sampling, unloading, impurity removal, and warehousing. A grain suction machine is a common grain processing equipment suitable for bulk conveying of various small granular materials such as rice, wheat, and plastics. Its working principle is that the motor drives the spiral blades inside the rubber tube to rotate. The grain enters the collection port of the grain inlet. Under the action of the spiral blades, the grain in the collection port will rise along the spiral angle of the spiral blades. When it reaches the discharge port, it will be automatically unloaded due to gravity.

[0003] In traditional grain suction machines, the discharge component is typically installed in the desired location, and then the conveying hose is inserted into the grain pile for loading and unloading. However, after absorbing the surrounding grain, the fluidity of the granular grain and the inability of the hose to gradually penetrate deeper into the grain pile on its own cause pits to quickly form at the hose insertion point. Once these pits form, the end of the conveying hose is exposed to the air, preventing the feed inlet from being tightly wrapped by the grain. This makes it difficult for the spiral blades to achieve full-load, efficient conveying, resulting in decreased conveying efficiency. Furthermore, when the spiral blades spin idly in the pits, they continuously agitate a small amount of residual grain and air, which escapes from the pit opening, polluting the working environment. To maintain efficiency and the working environment, workers usually need to continuously push the grain above towards the pits to cover them, disrupting the continuity of operations and resulting in poor loading and unloading efficiency.

[0004] Therefore, those skilled in the art have provided an environmentally friendly grain unloading machine to solve the problems mentioned in the background art. Summary of the Invention

[0005] The technical problem solved by this invention is to provide an environmentally friendly grain unloading machine that can move and gather the surrounding grain and autonomously go deep into the grain for full-load transportation.

[0006] To solve the above problems, the present invention provides an environmentally friendly grain unloading machine, including a discharge shell, an axle-free auger installed inside the discharge shell, a soft rubber tube fixedly installed on the bottom side of the discharge shell and sleeved outside the axle-free auger, a grain inlet head clamped to the other end of the soft rubber tube, a cone head fixedly installed at the end of the grain inlet head, four feed ports equally spaced on the outer side of the grain inlet head, a rotating rod rotatably connected to the upper inner wall of each of the four feed ports, and a grain-dispensing plate fixedly connected to the outer wall of the rotating rod. The cone head is equipped with a grain shifting component, which includes a rotating shaft. When the rotating shaft rotates, it drives the lifting plate to move vertically back and forth through a guide moving component. The lifting plate is slidably connected with four sets of drive rods corresponding to the four feed ports. Each drive rod is fixedly connected to a fixing block on its outer wall, and the fixing block and the opposite side of the lifting plate are fixedly connected to a spring. The grain shifting plate is equipped with offset transmission components on both sides. When the movement of the lifting plate does not cause the spring to deform, the drive rod will drive the grain shifting plate to deflect back and forth through the offset transmission components. It also includes four sets of vibration anti-deviation components. The vibration anti-deviation components include a sleeve installed in the grain feeding plate. The two fixed blocks are rotatably connected to a rotating rod two on opposite sides. When the movement of the lifting plate causes the spring to deform, the rotating rod two will be rotated through the linkage transmission assembly, and the sleeve will be reciprocated through the retraction assembly.

[0007] Further: The guide moving assembly includes a circulation groove 1 opened on the outer wall of the rotating shaft. The bottom of the rotating shaft is rotatably connected to the center of the end of the feed head away from the soft rubber tube. The inside of the lifting plate is fixedly connected to the circulation groove 1, and the outer wall of the ball is slidably connected to the inner wall of the circulation groove 1. Each drive rod is slidably connected to the inner wall of the feed head.

[0008] Further: The offset transmission assembly includes: The cover is fixedly connected to the inner wall of the feed inlet. The two sides of the grain feeding plate are respectively an inner concave inclined surface and an outer convex inclined surface. A gear is fixedly connected to the end of the rotating rod. The lower outer wall of the drive rod is provided with a tooth groove corresponding to the gear, and the outer wall of the gear meshes with the inner wall of the tooth groove for transmission.

[0009] Further: The linkage transmission assembly includes: Two slip rings are symmetrically arranged on the outer wall of the rotating rod 2. Each of the two slip rings is hinged to a connecting rod at one end, and the other end of each connecting rod is hinged to the bottom of the lifting plate. Two spiral grooves are symmetrically formed on the outer wall of the rotating rod 2 corresponding to the slip ring. The slip ring is slidably connected to the outer wall of the rotating rod 2 through the spiral grooves. A pull rope is wound around the center of the outer wall of the rotating rod 2. Tension springs are fixedly connected to the sides of the two fixed blocks that are close to each other. The ends of the two tension springs that are close to each other are fixedly connected to the ends of the two slip rings that are far apart.

[0010] Further: The retracting component includes: A sliding groove, wherein the sleeve is fitted onto the center of the outer wall of the rotating rod, and the other end of the pull rope passes through the inside of the grain inlet head and is wrapped around the outer wall of the sleeve; The sliding groove is formed through the inner wall of the grain feeding plate. The outer wall of the rotating rod is slidably connected to the inner wall of the sliding groove. The inner wall of the sliding groove is symmetrically provided with limit grooves. The outer wall of the rotating rod is symmetrically fixedly connected to the limit grooves, and the outer wall of the limit block is slidably connected to the inner wall of the limit groove. The inner wall of the sleeve is provided with a second circulation groove. The inner wall of the sleeve is slidably connected to the center of the outer wall of the rotating rod through the second circulation groove. Torsion springs are fixedly connected to both ends of the sleeve, and the other ends of the two torsion springs are fixedly connected to the inner walls of both sides of the grain feeding plate.

[0011] Furthermore, the grain unloader also includes a deep dispersing component, which is disposed at the outer conical tip of the cone head.

[0012] Further: The deep disintegration component includes a lifting rod, the tip of the cone head is provided with a circular groove corresponding to the lifting rod, and the inner wall of the circular groove is provided with a spiral groove II. The outer wall of the lifting rod is slidably connected to the inner wall of the circular groove through the spiral groove II. The outer wall of the lifting rod is inclinedly connected with loosening rods at equal intervals, and the other ends of several loosening rods are fixedly connected to the chassis.

[0013] Furthermore, the top of the lifting plate is symmetrically and fixedly connected with support rods, and the top of the support rods is provided with a limiting groove corresponding to the chassis. The outer wall of the chassis is slidably connected to the inner wall of the limiting groove.

[0014] Furthermore: A drive motor 1 for driving the shaftless dragon to rotate is fixedly installed on the outer side of the discharge shell, and a drive motor 2 is fixedly connected to the inner wall of the tip of the cone. One end of the output shaft of the drive motor 2 is fixedly connected to the end of the rotating shaft.

[0015] The effects of the above solution are as follows: 1. This invention, through the cooperation of a rotating shaft and a lifting plate, enables four sets of drive rods to move up and down, allowing four grain-dispensing plates located at the feed inlet to move back and forth. Utilizing the convex and concave shape of the grain-dispensing plates, when dispensing inwards, the grain is firmly confined to the concave surface of the dispensing plate, pushing the surrounding grain towards the central conveying area of ​​the feed head. This achieves automatic and real-time filling of the depressions, effectively maintaining a high material concentration at the feed head. Simultaneously, when dispensing outwards, the convex inclined surface significantly reduces the contact resistance with the grain pile, creating a significant resistance difference between inward and outward swings. This resistance difference is converted into a continuous axial propulsive force acting on the entire feed head through the drive rods and lifting plate, driving the feed head to actively drill deeper into the grain pile. This expands the effective working range after single-point placement, ensuring that the feed head is always covered and enveloped by grain, thus guaranteeing a clean working environment.

[0016] 2. During grain loading and unloading, grain piles often form locally compacted or sticky hard lumps due to uneven moisture distribution, differences in particle composition, or different storage times. This invention, through the cooperation of springs and fixing blocks, allows a single set of grain-distributing plates to stop when encountering relatively compacted or sticky grain, without affecting the normal grain-gathering ability of other grain-distributing plates. At the same time, to avoid deviation in the overall movement direction due to unilateral obstruction, the lifting plate can be lowered separately during the spring compression, allowing the rotating rod two to drive the sleeve back and forth through the pull rope. This causes the obstructed grain-distributing plate to axially reciprocate along the rotating rod one, effectively loosening the compacted grain and restoring its fluidity. This ensures that the overall propulsion direction will not deviate due to unilateral obstruction when the equipment encounters local uneven working conditions, maintaining the stability and straightness of the drilling trajectory.

[0017] 3. When the grain inlet head drills downwards, the present invention can drive the lifting rod to move up and down through the lifting plate. With the cooperation of the spiral groove two, several loosening rods can loosen and disperse the grain below in advance during the drilling process, reducing the main thrust required to drive the grain inlet head to drill. Thus, a deeper drilling depth can be achieved with the same power, avoiding rapid attenuation due to the increasingly dense bottom of the grain pile. This allows the equipment to effectively approach and clean up the leftover material at the bottom edge of the silo, greatly improving the grain recovery rate of a single operation and reducing the need for subsequent manual cleaning.

[0020] The technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Example 1, please refer to Figures 1-8 An environmentally friendly grain unloading machine includes a discharge shell 1, inside which a shaftless auger 2 is installed. A soft rubber tube 4 is fixedly installed on the bottom side of the discharge shell 1 and sleeved on the outside of the shaftless auger 2. The other end of the soft rubber tube 4 is clamped to a grain inlet head 5. A cone head 6 is fixedly installed at the end of the grain inlet head 5. Four feed ports 7 are opened at equal intervals on the outer side of the grain inlet head 5. A rotating rod 808 is rotatably connected to the upper inner wall of each of the four feed ports 7. A grain-pulling plate 809 is fixedly connected to the outer wall of the rotating rod 808.

[0022] A drive motor 3 is fixedly installed on the outer side of the discharge housing 1 to drive the shaftless dragon 2 to rotate. A drive motor 801 is fixedly connected to the inner wall of the tip of the cone head 6. One end of the output shaft of the drive motor 801 is fixedly connected to the end of the rotating shaft 802.

[0023] The cone head 6 is equipped with a grain shifting component 8. The grain shifting component 8 includes a rotating shaft 802. When the rotating shaft 802 rotates, it drives the lifting plate 803 to move vertically back and forth through the guide moving component. The lifting plate 803 is slidably connected with four sets of drive rods 804 corresponding to the four feed ports 7. Each drive rod 804 is fixedly connected to a fixing block 807 on its outer wall. The fixing block 807 and the opposite side of the lifting plate 803 are jointly fixedly connected to a spring 806. The grain shifting plate 809 is equipped with offset transmission components on both sides.

[0024] Specifically, when using this environmentally friendly grain unloading machine, first install the discharge housing 1 at the location where the grain needs to be transported, then insert the grain inlet head 5 at the other end of the soft rubber tube 4 vertically downward into the grain pile to be transported, and then start the drive motor 3, so that the shaftless spiral 2 located between the discharge housing 1 and the grain inlet head 5 rotates, so that the grain to be transported can rise along the spiral angle direction of the spiral blades of the shaftless spiral 2, and after reaching the discharge port of the discharge housing 1, it will automatically unload the grain by gravity.

[0025] During the loading and unloading of grain, the drive motor 801 drives the rotating shaft 802 to rotate. When rotating, the shaft 802 uses a guide moving component to drive the lifting plate 803 to move vertically back and forth. During the lifting of the lifting plate 803, the spring 806 and the fixed block 807 simultaneously drive the drive rod 804 to move up and down. When the movement of the lifting plate 803 does not cause deformation of the spring 806, the drive rod 804 will drive the grain-dispensing plates 809 to reciprocate through the offset transmission component, allowing the four grain-dispensing plates 809 located at the feed inlet 7 to move back and forth. Utilizing the convex and concave shape of the grain-dispensing plates 809, when dispensing inwards, they can... The grain is firmly confined to the concave surface of the grain feeding plate 809, and the surrounding grain is pushed towards the central conveying area of ​​the grain feeding head 5. This achieves automatic and real-time filling of the depression, effectively maintaining a high material concentration at the grain feeding head 5. At the same time, when pushing outward, the convex inclined surface can significantly reduce the contact resistance with the grain pile, creating a significant resistance difference between inward and outward swinging. This resistance difference is converted into a continuous axial propulsion component acting on the entire grain feeding head 5 through the drive rod 804 and the lifting plate 803, driving the grain feeding head 5 to actively drill into the depth of the grain pile, expanding the effective working range after single-point placement, ensuring that the grain feeding head 5 can be covered and wrapped by grain at all times, and ensuring a clean working environment.

[0026] Furthermore, during the loading and unloading of grain, grain piles often form locally compacted or sticky hard lumps due to uneven moisture distribution, differences in particle composition, or different storage times. To prevent all grain-dispensing plates 809 from failing to operate when encountering relatively compacted or sticky grain on a certain group of dispensing plates 809, the cooperation of spring 806 and fixing block 807 ensures that when the resistance of a grain-dispensing plate 809 on one side is too high, the fixing block 807 cannot move. This allows the lifting plate 803 to still drive the normal operation of the remaining grain-dispensing plates 809 by compressing the spring 806 on that side, thus enhancing its grain-gathering ability.

[0027] Furthermore, the guide moving assembly includes a circulation groove 805 formed on the outer wall of the rotating shaft 802. The bottom of the rotating shaft 802 is rotatably connected to the center of the end of the feed head 5 away from the soft rubber tube 4. The inside of the lifting plate 803 is fixedly connected to the circulation groove 805, and the outer wall of the ball is slidably connected to the inner wall of the circulation groove 805. Each drive rod 804 is slidably connected to the inner wall of the feed head 5.

[0028] Specifically, during the movement of the lifting plate 803, the driving rod 804 restricts the lifting plate 803 so that it can only move up and down and cannot rotate. At this time, in conjunction with the circulation groove 805 and the ball bearings, the lifting plate 803 can only move up and down under the rotation of the rotating shaft 802.

[0029] Furthermore, the offset transmission assembly includes: The cover 812 is fixedly connected to the inner wall of the feed inlet 7. The two sides of the grain feeding plate 809 are respectively an inner concave inclined surface and an outer convex inclined surface. The end of the rotating rod 808 is fixedly connected to the gear 810. The lower outer wall of the drive rod 804 is provided with a tooth groove 811 corresponding to the gear 810, and the outer wall of the gear 810 meshes with the inner wall of the tooth groove 811 for transmission.

[0030] Specifically, during the lifting and lowering movement of the drive rod 804, the gear 810 and the tooth groove 811 work together to enable the drive rod 804 to drive the rotating rod 808 to rotate back and forth, so that the four grain-dispensing plates 809 located at the feed inlet 7 can be dispensing back and forth.

[0031] In Example 2, based on the above examples, the environmentally friendly grain unloading machine also includes four sets of vibration anti-deviation components 9. The vibration anti-deviation components 9 include a sleeve 906 installed in the grain feeding plate 809, and two rotating rods 901 are rotatably connected to the opposite sides of the two fixed blocks 807.

[0032] The linkage drive assembly includes: Two slip rings 902 are symmetrically arranged on the outer wall of the rotating rod 901. The ends of the two slip rings 902 are hinged to the connecting rods 903, and the other ends of the two connecting rods 903 are hinged to the bottom of the lifting plate 803. Two spiral grooves 904 are symmetrically opened on the outer wall of the rotating rod 901 corresponding to the slip ring 902. The slip ring 902 is slidably connected to the outer wall of the rotating rod 901 through the spiral grooves 904. A pull rope 905 is wound around the center of the outer wall of the rotating rod 901. Tension springs 911 are fixedly connected to the sides of the two fixed blocks 807 that are close to each other. The ends of the two tension springs 911 that are close to each other are fixedly connected to the ends of the two slip rings 902 that are far apart.

[0033] Specifically, to avoid the situation where movement is difficult due to obstruction on one side, the operation of the other grain feeding plates 809 causes the overall direction of the grain feeding head 5 to rotate and shift around the obstructed side as the axis. During the period when the spring 806 on the obstructed side is compressed, the fixed block 807 cannot move down. Thus, through the cooperation of the connecting rod 903 and the slip ring 902, the two slip rings 902 on the rotating rod 901 on the obstructed side can move closer to each other. At this time, through the cooperation of the spiral groove 904 and the ball inside the slip ring 902, when the two slip rings 902 move closer to each other, they can synchronously drive the rotating rod 901 on the obstructed side to rotate, thereby pulling the pull rope 905.

[0034] Furthermore, the expansion and contraction components include: The sliding groove 907 and the sleeve 906 are fitted on the center of the outer wall of the rotating rod 808. The other end of the pull rope 905 passes through the inside of the grain feed head 5 and is wrapped around the outer wall of the sleeve 906.

[0035] The sliding groove 907 is opened through the inner wall of the grain feeding plate 809. The outer wall of the rotating rod 808 is slidably connected to the inner wall of the sliding groove 907. The inner wall of the sliding groove 907 is symmetrically provided with limiting grooves 908. The outer wall of the rotating rod 808 is symmetrically fixedly connected to the limiting groove 908 with a limiting block 909, and the outer wall of the limiting block 909 is slidably connected to the inner wall of the limiting groove 908. The inner wall of the sleeve 906 is provided with a circulation groove 910. The inner wall of the sleeve 906 is slidably connected to the center of the outer wall of the rotating rod 808 through the circulation groove 910. Torsion springs 912 are fixedly connected to both ends of the sleeve 906. The other ends of the two torsion springs 912 are fixedly connected to the inner walls of both sides of the grain feeding plate 809.

[0036] Specifically, a sleeve 906 is fitted onto the center of the outer wall of the first rotating rod 808, and the other end of the pull rope 905 passes through the inside of the grain inlet head 5 and is wound around the outer wall of the sleeve 906. This allows the second rotating rod 901 to rotate, via the pull rope 905, causing the sleeve 906 located at the center of the outer wall of the first rotating rod 808 to rotate. Through the cooperation of the limiting groove 908 and the limiting block 909, while the first rotating rod 808 can rotate and drive the grain-dispensing plate 809, it can also move back and forth a short distance along its own axis. When the grain-dispensing plate 809 cannot move, the first rotating rod 808 will also be unable to move. When the device rotates, the ball bearings installed on the rotating rod 808 via the second circulation groove 910 allow the sleeve 906 to make axial back-and-forth contact. This causes the obstructed grain-pulling plate 809 to vibrate axially along the rotating rod 808 in a short amplitude, effectively loosening the compacted grain and restoring its fluidity. This ensures that the overall propulsion direction will not deviate due to obstruction on one side when the equipment encounters local uneven working conditions, maintaining the stability and straightness of the drilling trajectory. After the vibration loosens the grain, the spring force of the tension spring 911 and the torsion spring 912 is used to reset the state of the pull rope 905 on the sleeve 906 and the rotating rod 808, respectively.

[0037] In embodiment three, based on the above embodiments, the deep dispersing component 10 includes a lifting rod 1001. The tip of the cone 6 is provided with a circular groove 1002 corresponding to the lifting rod 1001, and the inner wall of the circular groove 1002 is provided with a spiral groove 1003. The outer wall of the lifting rod 1001 is slidably connected to the inner wall of the circular groove 1002 through the spiral groove 1003. The outer wall of the lifting rod 1001 is inclinedly connected with loosening rods 1004 at equal intervals. The other ends of several loosening rods 1004 are fixedly connected to the chassis 1005.

[0038] The top of the lifting plate 803 is symmetrically fixedly connected with support rods 1006. The top of the support rods 1006 is provided with a limiting groove 1007 corresponding to the chassis 1005. The outer wall of the chassis 1005 is in contact with the inner wall of the limiting groove 1007 and is slidably connected.

[0039] Specifically, when the feed head 5 drills downwards, loosening rods 1004 are inclinedly connected at equal intervals to the outer wall of the lifting rod 1001. The other ends of several loosening rods 1004 are fixedly connected to the base 1005. Support rods 1006 are symmetrically fixedly connected to the top of the lifting plate 803. The top of the support rod 1006 has a limiting groove 1007 corresponding to the base 1005. The outer wall of the base 1005 and the inner wall of the limiting groove 1007 are slidably connected in contact, so that the lifting plate 803 can drive the support rod 1006 to move up and down, thereby synchronously driving the lifting rod 1001 to move up and down. At this time, a circular groove 1002 is opened at the tip of the cone head 6 corresponding to the lifting rod 1001, and the inner wall of the circular groove 1002 has a... The spiral groove 1003 connects the outer wall of the lifting rod 1001 to the inner wall of the circular groove 1002. During the lifting motion of the lifting rod 1001, the spiral groove 1003 engages with the ball bearings on the lower side of the lifting rod 1001, allowing the lifting rod 1001 to rotate during the lifting process. This loosens and disperses the grain below during drilling, reducing the main thrust required to drive the grain feed head 5 into the hole. As a result, a deeper drilling depth can be achieved with the same power, preventing rapid attenuation due to the increasingly dense bottom of the grain pile. This allows the equipment to effectively approach and clean up the remaining material at the bottom of the silo, significantly improving the grain recovery rate of a single operation and reducing the need for subsequent manual cleaning.

[0040] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0041] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
