A wind-powered hoist for preventing grain damage

Abstract

The utility model discloses a wind lift for preventing grain damage, and specifically relates to the field of crop processing. The front of the moving block is fixedly connected with a fixed rod, and the opposite ends of the fixed rods on the front and rear sides are fixedly connected with deformable metal springs. When the material is blocked in the access pipe, the two sliding rods are pulled outward, and the sliding rods drive the middle position of the metal springs to be pulled outward through the connecting block, so that the diameter of the access pipe becomes thicker, so that the place where the material is blocked becomes wider, so that the gravity of the material above pushes the blocked material, and the blocked material is pushed out of the inside of the access pipe. When the metal spring is pulled outward, the arc of the metal spring deformation becomes larger, so that the fixed rods on both sides slide upward along the rolling groove, and at the same time drive the moving block to slide along the inside of the sliding groove, so as to achieve the guidance of the fixed rod when moving. Thereby, the effect of preventing material blockage is achieved, and the surface of the material will not be damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of crop processing, in particular to a wind hoist for preventing grain damage. Background Art

[0002] Air elevators can be divided into low-pressure and high-pressure conveying according to pressure. Generally, low-pressure conveying uses fans, and high-pressure conveying uses air compressors. That is, air (wind or compressed air) is used to suspend materials in containers and pipes, and then the air flows in the pipes to bring the materials to the desired destination, and then the wind or air is separated from the materials.

[0003] A Chinese patent discloses a wind-driven vibration elevator with a publication number of CN213201504U, and the application date is 2020.08.25. This patented technology changes the design of the sunflower seed suction port, adds a stirring mechanism at the suction port, and at the same time increases the suction volume of sunflower seeds and avoids the occurrence of sunflower seed jamming. In addition to the vibration of the vibration head, the combined effect of the stirring spiral fork and the sunflower seed conical pump suction port can greatly improve the lifting efficiency. However, although there will be no jamming problem through the setting of the stirring thread fork during the above-mentioned feeding process, when the stirring thread fork contacts the surface of the material, it will cause damage to the surface of the material, which is not convenient for the preservation of the material after discharge. Therefore, a mechanism is needed to prevent blocking during feeding, and it will not damage the surface of the material. Therefore, the inventor provides a wind-driven elevator that avoids grain damage to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0004] The utility model aims to provide a wind lift which can avoid grain damage, prevent material accumulation when the device is in use, and will not damage the surface of the material.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The wind lifter that avoids grain damage, when the material is blocked in the access pipe, pulls the two sliding rods outward, and the sliding rod drives the middle position of the metal spring to pull outward through the connecting block, so that the diameter of the access pipe becomes thicker, so that the place where the material is blocked becomes wider, so that the gravity of the material above pushes the blocked material, and pushes the blocked material out of the access pipe.

After the blocked material is cleared, the sliding rod is moved in the opposite direction, and the metal spring returns to its original position. Thereby achieving the effect of preventing material blockage without damaging the surface of the material.

[0014] In addition, the wind elevator should be used to avoid damage to grains. After the guide tube machine is transformed into a round feeding tube, since there are no edges and corners inside the guide tube, it is not easy for the grains to directly collide with the inside of the guide tube. After field tests, the granular materials sucked in from low places, such as grains and corn, have no damage to the appearance of the granular materials during the entire lifting and transfer process. The wind conveying force is truly realized in the process of transferring the granular materials from low places to high places, which is convenient for farmers to collect and store, and the storage period of the granular materials is guaranteed.

DETAILED DESCRIPTION

[0022] like Figure 1 As shown, a wind lift for preventing grain damage comprises a fixed box 10, wherein the interior of the fixed box 10 is hollow and the top is open, and a material guide pipe 12 for conveying materials is installed inside the fixed box 10.

[0023] refer to Figure 1 , 3 The top of the fixed box 10 is fixedly connected with a fan 11, and the output end of the fan 11 is fixedly connected with a guide pipe 12. The guide pipe 12 first extends downward, then extends to the right, and then extends forward. Finally, the guide pipe 12 extends to the right and is fixedly connected with a discharge tube 13. The fan 11 is driven by a motor.

[0024] Preferably, a three-way connector 14 is provided on the front side of the guide tube 12. When in use, the fan 11 is started by an external power supply, and the fan 11 draws air from the outside and discharges it into the guide tube 12, and finally discharges it from the discharge barrel 13. In this process, the material is placed into the three-way connector 14, and the material moves in the direction of the airflow, and finally discharged from the discharge barrel 13, thereby achieving the effect of material transmission.

[0025] Preferably, the guide pipe 12 is a smooth cylindrical design with rounded corners. Since the cross-section of the commonly used feeding pipe is rectangular, in the process of transferring the material from the bottom to the top, under the negative pressure air supply of the fan 11, it is easy for the granular material at a relatively low position to collide with the cylinder wall at high speed, and then the surface of the material will be broken, causing the grains or corn to be damaged at the discharge port, affecting storage. However, after the guide pipe 12 adopts a cylindrical design, since there are no edges and corners inside the guide pipe 12, it is not easy for the grains to directly collide with the inside of the guide pipe 12. According to field tests, the granular materials sucked in from the bottom, such as grains, corn, etc., have no appearance damage to the granular materials during the entire lifting and transfer process, which truly realizes the integrity of the granular materials during the entire process of transporting from the bottom to the top by the wind conveying force, which is convenient for farmers to collect and store, and the storage period of the granular materials is guaranteed.

[0026] refer to Figure 2 , 3 A mounting plate 15 is fixedly connected to the left side of the interior of the fixed box 10, and a feed box 20 is fixedly connected to the top of the mounting plate 15 for facilitating the introduction of materials into the guide tube 12. The feed box 20 is fixed to the top of the mounting plate 15 by means of a threaded connection with the mounting plate 15 by bolts.

[0027] Specifically, a feed slot 21 is provided at the top of the feed box 20, and an introduction plate 22 is fixedly connected to the inside of the feed slot 21. An introduction slot 23 is provided at the front side of the feed slot 21, and the introduction slot 23 is in a "Y" shape. An access pipe 24 is fixedly connected to the bottom of the introduction slot 23, and the access pipe 24 is fixedly connected to the three-way connector 14 when in use.

[0028] Preferably, the introduction plate 22 is designed to be inclined with the front higher and the back lower. When the material is poured into the feed trough 21, the material contacts the surface of the introduction plate 22. Due to natural gravity, the material slides downward into the introduction trough 23. Because the introduction trough 23 is high at both ends and low in the middle, the material will enter the bottom of the introduction trough 23 and finally be discharged into the inside of the guide pipe 12 through the access pipe 24.

[0029] During the use of the above device, since the access pipe 24 is relatively thin, the material may be guided too fast, and the material surfaces may be squeezed and blocked inside the access pipe 24, thereby affecting the feeding. Therefore, a dredging structure is proposed.

[0030] refer to Figure 4 , 5 6. Access grooves 30 are provided on the left and right sides of the access tube 24. Guide blocks 31 are fixedly connected to the upper and lower ends of the left and right sides of the two access grooves 30 respectively. A rolling groove 32 is provided on the front of the guide block 31. Sliding grooves 33 are provided on the left and right sides of the guide block 31. Moving blocks 34 are slidably connected to the opposite sides of the two sliding grooves 33. A fixing rod 35 is fixedly connected to the front of the moving block 34. Metal springs 36 are fixedly connected to the opposite ends of the fixing rods 35 on the front and rear sides.

[0031] Specifically, a pair of translation blocks 37 are fixedly connected to the outer sides of the two metal spring sheets 36, and a movable sliding rod 39 is rotatably connected to the opposite sides of the pair of translation blocks 37 through a movable axis. A through groove 38 is opened on the opposite side of the access groove 30, and the sliding rod 39 is slidably connected to the through groove 38. The through groove 38 is adapted to the shape of the sliding rod 39, so as to guide the sliding rod 39 when it moves.

[0032] When the material is blocked in the access pipe 24, the two sliding rods 39 are pulled outwards, and the sliding rods 39 drive the middle position of the metal spring 36 to be pulled outwards through the translation block 37, so that the diameter of the access pipe 24 becomes thicker, so that the place where the material is blocked becomes wider, so that the gravity of the material above pushes the blocked material, and pushes the blocked material out of the access pipe 24. When the metal spring 36 is pulled outwards, the arc of the metal spring 36 deformation becomes larger, so that the fixed rods 35 on both sides slide upward along the rolling groove 32, and at the same time drive the moving block 34 to slide along the inside of the sliding groove 33, so as to guide the movement of the fixed rod 35. After the blocked material is cleared, the sliding rod 39 is moved in the opposite direction, so that the metal spring 36 returns to its original position.

[0033] Specifically, a bidirectional cylinder 41 is fixedly connected to the rear side of the access pipe 24, and a connection block 40 is fixedly connected to the left and right output ends of the bidirectional cylinder 41, and the connection block 40 is fixedly connected to the corresponding sliding rod 39. When in use, the bidirectional cylinder 41 is started by an external power supply, and the output ends on both sides of the bidirectional cylinder 41 extend outward, driving the two sliding rods 39 to move back to each other, so that the metal spring sheet 36 is pulled outward. Similarly, when the output ends on both sides of the bidirectional cylinder 41 shrink inward, the two sliding rods 39 are driven to move toward each other and return to their original positions.

[0034] Preferably, baffles 42 are fixedly connected to the opposite ends of the top sides of the two access grooves 30, and the baffles 42 can prevent materials from entering the interior of the access groove 30 from the top of the access groove 30 and affecting the deformation of the metal spring piece 36; inclined grooves 43 are opened at the opposite ends of the bottom of the two access grooves 30. When the metal spring piece 36 is deformed into a "C" shape, the material expands toward the blockage so that the material fits the surface of the metal spring piece 36, and finally the material moves downward along the bottom arc of the metal spring piece 36, and finally slides downward along the inclined groove 43 to be discharged from the access pipe 24.

[0035] The working principle of the utility model is as follows: when the material is blocked in the access pipe 24, the two sliding rods 39 are pulled outward, and the sliding rods 39 drive the middle position of the metal spring 36 to be pulled outward through the translation block 37, so that the diameter of the access pipe 24 becomes thicker, so that the place where the material is blocked becomes wider, and the gravity of the material above pushes the blocked material to push the blocked material out of the access pipe 24. When the metal spring 36 is pulled outward, the metal spring 36 is deformed and bent inward, so that the fixed rods 35 on both sides slide upward along the rolling groove 32, and at the same time drive the moving block 34 to slide along the inside of the sliding groove 33, so as to guide the movement of the fixed rod 35. When the metal spring is deformed, the upper and lower ends will move toward the middle, and the moving block 34 is set to slide along the inside of the sliding groove 33, which can prevent the metal spring 34 from detaching from the inside of the guide block 31. After the blocked material is dredged, the sliding rod 39 is moved in the opposite direction, so that the metal spring 36 returns to its original position.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
