Description

Technical Field

[0001] The present invention relates to the technical field of rice production, and in particular to an automatic rice transport and bagging device. Background Art

[0002] During the automated production and processing of rice, bagging is required by a bagging machine, and the bagging discharge port of the existing automatic bagging device for rice processing is fixed. For example, an automatic bagging device for rice processing disclosed in announcement number CN210942480U includes a box body, a feed trough is opened at the center of the top wall of the box body, a funnel is fixedly installed on the top wall of the box body at the opening at the upper end of the feed trough, mounting plates are symmetrically fixedly connected to the front and rear sides of the top wall of the box body, a sealed bag conveying device is arranged between the two mounting plates, a base is fixedly connected to the lower side wall of one side of the box body, a conveying device is arranged on the base, and a sealed bag sealing device and a sealed bag cutting device are arranged from top to bottom on the side wall of the box body close to the base.

[0003] In order to control costs and maintain good tensile and compressive strength, most rice packaging bags on the market are nylon bags. When bagging rice, the existing automatic bagging device for rice processing has a fixed feeding port (usually dropping the material from the middle downward). This can easily cause incomplete filling of the bottom corners of the nylon packaging bag, resulting in wrinkles. This can lead to overflow after quantitative bagging, causing waste and difficulty in subsequent bag sealing. In addition, vertical downward dropping can easily cause dust diffusion, affecting the hygiene and safety of the packaging environment. Summary of the Invention

[0004] The present invention provides an automatic rice transport and bagging device, which solves the problem in the prior art that the bottom corners of both sides of the packaging bag are not completely filled, which easily causes dust diffusion.

[0005] The technical solution of the present invention is as follows: A rice automatic transport and bagging device includes a conveyor line, a drying box located above the conveyor line, and a bagging mechanism located at the discharge end of the conveyor line, wherein the bagging mechanism includes: The collecting hopper is used to store the rice transported by the conveyor line; The sub-bin is integrally connected to the bottom of the collecting hopper and is used to separate and store the rice falling from the collecting hopper; Fixed bracket, fixed to the outside of the bottom of the distribution silo; The movable bracket is horizontally arranged below the fixed bracket; The material dispensing component is located below the material dispensing bin and can be rotated on a movable bracket to adjust the material dispensing direction; An elastic cloth bag is used to guide the rice in the distribution bin to the cloth component; A driving component is arranged on a fixed bracket; The traction component drives the movable bracket and the cloth component to move up and down under the drive component; The feeding component spirally guides the rice in the collecting hopper into the sub-bin when the driving component drives the movable bracket and the distribution component to rise, and stops feeding when the driving component drives the movable bracket and the distribution component to descend.

[0006] The spring support rod is used to enable the movable bracket to elastically rise and fall relative to the fixed bracket.

[0007] Preferably, the driving component includes a motor, the motor is fixed to the bottom surface of the fixed bracket, the output shaft of the motor passes through the fixed bracket and is fixed with a worm, and the upper end of the worm is fixed with a ratchet.

[0008] Preferably, the traction component includes a first driven shaft, which is perpendicular to the motor output shaft and rotatably connected to a fixed bracket. A worm wheel meshing with the worm is fixed on the first driven shaft, and reels are fixed at both ends of the first driven shaft, and a traction belt is fixed on the inner side of the reel.

[0009] Preferably, the unloading component includes a second transmission shaft, which is rotatably connected to the distribution bin, and an auger extending into the collecting hopper is fixed to the outer side of the second transmission shaft. The lower end of the second transmission shaft passes through the outside of the distribution bin and is fixed with a transmission disk. The inner side of the transmission disk is rotatably connected to a ratchet through a rotating shaft, and the inner side of the transmission disk is clamped with a metal spring that contacts the ratchet. The inner side of the transmission disk is provided with a holding portion that can block the ratchet and lock the ratchet when the ratchet is reversed.

[0010] Preferably, the fabric component includes a bent tube, which is rotatably connected to the movable bracket through a pin shaft, a fixing ring is fixed to the outer side of the bottom of the bent tube, hanging rods are fixed on both sides of the fixing ring, the lower end of the traction belt is fixed to the hanging rod, and a baffle rod is fixed on the outer wall of the bent tube for contacting the movable bracket when the traction belt is pulled back.

[0011] Preferably, an arc-shaped bayonet for limiting the traction belt is provided on the side surface of the movable bracket, and the traction belt passes around the arc-shaped bayonet.

[0012] Preferably, an electromagnetic discharge valve is provided on the inner side of the bent pipe, and the electromagnetic discharge valve is closed when the bent pipe descends and opened when the bent pipe rises.

[0013] Preferably, the upper end of the elastic cloth bag is connected to the bottom of the distribution bin, and the lower end of the elastic cloth bag is connected to the upper end of the elbow.

[0014] The beneficial effects of the present invention are: The present invention realizes automatic control of the bagging mechanism to load materials when it is rising and stop feeding materials when it is descending by cooperating with the driving component and the traction component. Specifically, when the motor rotates forward, the traction belt lowers the movable bracket and the cloth component to a height position close to the bottom cavity of the packaging bag, and the unloading component starts feeding materials. At the same time, when the motor rotates backward, the traction belt pulls the cloth component to rotate inward, and the unloading component starts to feed materials to the sub-bin. In the present invention, the cloth component can rotate on the movable bracket. Through the pulling of the traction belt, the bent pipe can be synchronously rotated inward with the pin shaft as the rotation fulcrum, thereby adjusting the feeding direction and ensuring that the rice is first filled into the bottom corners of the packaging bag during the initial bagging, thereby preventing the bottom corners from being incompletely filled and wrinkles from occurring. The spring support rod in the present invention enables the movable bracket to be elastically raised and lowered relative to the fixed bracket. In this way, when the traction belt pulls the cloth component to rotate inward, the movable bracket can maintain a relatively stable height position, ensuring that the height of the bent pipe does not change much, providing sufficient time for filling the bottom corners on both sides of the packaging bag. When the motor reverses and the traction belt pulls the cloth component and the movable bracket to rise, the position height of the two bent pipes can rise as the bagging height increases, thereby preventing the lower ends of the two bent pipes from being covered by the rice, and at the same time maintaining a small distance at the rice bagging height to reduce dust diffusion.

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1 、 Figure 2 and Figure 3The present invention provides a technical solution: a rice automatic transport and bagging device, comprising a conveyor line 1, a drying box 2 located above the conveyor line 1, and a bagging mechanism 3 located at the discharge end of the conveyor line 1. The bagging mechanism 3 comprises a collecting hopper 31, a material distribution bin 32, an elastic cloth bag 33, a cloth component 34, a driving component 35, a traction component 36, a material discharge component 37, a fixed bracket 38, a movable bracket 39, and a spring support rod 310. The collecting hopper 31 is used to store the rice transported by the conveyor line 1, and the material distribution bin 32 is integrally connected to the bottom of the collecting hopper 31 for separating and storing the rice falling from the collecting hopper 31. The bracket 38 is fixed to the bottom outer side of the distribution bin 32, the movable bracket 39 is horizontally arranged below the fixed bracket 38 and can move up and down relative to the fixed bracket 38, the cloth component 34 is located below the distribution bin 32 and can rotate on the movable bracket 39 to adjust the discharge direction, the elastic cloth bag 33 is used to guide the rice in the distribution bin 32 to the cloth component 34, the driving component 35 is arranged on the fixed bracket 38, and the traction component 36 drives the movable bracket 39 and the cloth component 34 to do the lifting movement under the drive of the driving component 35. The discharge component 37 is driven by the driving component 35 to drive the movable bracket 39 and the cloth component 34 to rise. The rice in the collecting hopper 31 is spirally guided into the distribution bin 32, and the feeding is stopped when the driving component 35 drives the movable bracket 39 and the cloth component 34 to descend. The spring strut 310 is used to enable the movable bracket 39 to elastically rise and fall relative to the fixed bracket 38. When the driving component 35 rotates forward, the traction component 36 lowers the movable bracket 39 and the cloth component 34 to a height position close to the bottom cavity of the packaging bag, and the unloading component 37 starts to feed. At the same time, the driving component 35 reverses the traction component 36 to pull the cloth component 34 to rotate inward, and the unloading component 37 starts to feed the distribution bin 32, and the spring strut 310 enables the movable bracket 39 to rotate downward. It can be elastically raised and lowered relative to the fixed bracket 38, so that when the traction component 36 pulls the cloth component 34 to rotate inward, the movable bracket 39 can maintain a relatively stable height position, ensuring that the height of the cloth component 34 does not change much, providing sufficient time for filling the bottom corners on both sides of the packaging bag. When the driving component 35 reverses the traction component 36 to pull the cloth component 34 and the movable bracket 39 to rise, the position height of the two cloth components 34 can rise as the bagging height increases, thereby preventing the lower ends of the two cloth components 34 from being covered by the rice, and at the same time maintaining a small distance at the rice bagging height to reduce dust diffusion.

[0019] See also Figure 4 and Figure 5 The driving component 35 includes a motor 351, which is fixed to the bottom surface of the fixed bracket 38. The output shaft of the motor 351 passes through the fixed bracket 38 and is fixed with a worm 352. The upper end of the worm 352 is fixed with a ratchet 353.

[0020] See also Figure 4 and Figure 6 The traction component 36 includes a first driven shaft 361, which is perpendicular to the output shaft of the motor 351 and is rotatably connected to the fixed bracket 38. A worm wheel 362 engaged with the worm 352 is fixed on the first driven shaft 361, and reels 363 are fixed at both ends of the first driven shaft 361. A traction belt 364 is fixed on the inner side of the reel 363.

[0021] See also Figure 4 and Figure 7 The unloading component 37 includes a second transmission shaft 371, which is rotatably connected to the sub-bin 32. The outer side of the second transmission shaft 371 is fixed with an auger 372 extending into the collecting hopper 31. The lower end of the second transmission shaft 371 passes through the outside of the sub-bin 32 and is fixed with a transmission disc 373. Figure 8 As shown, the inner side of the transmission disk 373 is rotatably connected to the ratchet 375 through the rotating shaft 374, and the inner side of the transmission disk 373 is clamped with a metal spring 376 that conflicts with the ratchet 375. The inner side of the transmission disk 373 is provided with a holding portion 377 that can block the ratchet 375 and lock the ratchet 353 when the ratchet 353 is reversed. The ratchet 353 and the ratchet 375 in the driving component 35 can lock the ratchet 353 when the motor 351 is reversed, so that the transmission disk 373 can rotate synchronously with the output shaft of the motor 351, driving the auger 372 to spirally transport the rice in the collecting hopper 31 to the distribution bin 32 as a supplement, realizing the function of automatically feeding the collecting hopper into the distribution bin, and ensuring the continuity and stability of the bagging process.

[0022] See also Figure 9 The cloth component 34 includes a curved tube 341, which is rotatably connected to the movable bracket 39 through a pin shaft 342. A fixing ring 344 is fixed to the outer side of the bottom of the curved tube 341, and hanging rods 345 are fixed on both sides of the fixing ring 344. The lower end of the traction belt 364 is fixed to the hanging rod 345. A stop rod 343 is fixed on the outer wall of the curved tube 341 for contacting the movable bracket 39 when the traction belt 364 is pulled back. The curved tube 341 can rotate on the movable bracket 39. Through the traction of the traction belt 364, the curved tube 341 can be synchronously rotated inward with the pin shaft 342 as the rotation fulcrum, thereby adjusting the feeding direction and ensuring that the rice is first filled to the bottom corners on both sides of the packaging bag during the initial bagging to prevent wrinkles caused by incomplete filling of the bottom corners.

[0023] See also Figure 2 and Figure 10 An arc-shaped bayonet 391 is provided on the side of the movable bracket 39 to limit the traction belt 364, and the traction belt 364 passes around the arc-shaped bayonet 391.

[0024] It should be noted that an electromagnetic discharge valve is provided on the inside of the curved pipe 341. The electromagnetic discharge valve closes when the curved pipe 341 descends and opens when the curved pipe 341 rises. This design ensures that rice will not leak out of the curved pipe 341 prematurely during the descending movement of the cloth component 34. The discharge will only begin when the cloth component 34 is in the correct position, thereby improving the accuracy and efficiency of bagging.

[0025] The upper end of the elastic cloth bag 33 is connected to the bottom of the distribution bin 32, and the lower end of the elastic cloth bag 33 is connected to the upper end of the curved pipe 341. The elastic cloth bag 33 connects the distribution bin 32 and the cloth component 34, and can flexibly adapt to the movement and rotation of the cloth component 34, ensuring that the rice is smoothly guided from the distribution bin 32 to the cloth component 34, avoiding the blockage or obstruction problems that may be caused by traditional rigid connections.

[0026] The working principle and use process of the present invention are as follows: the rice transported on the conveyor line 1 is dried in the drying box 2 and then enters the bagging mechanism 3. When the packaging bag is transported to the bottom of the bagging mechanism 3 through the production line, the motor 351 rotates forward to drive the worm 352. The engagement between the worm 352 and the worm wheel 362 drives the first driven shafts 361 on both sides to rotate, and then the reel 363 rotates and the traction belt 364 lowers the movable bracket 39 and the cloth component 34 to a height position close to the bottom cavity of the packaging bag. At this time, the two cloth components 34 and the movable bracket 39 are in the state as shown in FIG. Figure 11 As shown; The electromagnetic discharge valve in the bend pipe 341 is opened, so that the rice in the distribution bin 32 is guided to the bend pipe 341 through the elastic cloth bag 33 and output from the lower port of the bend pipe 341, and then the bottom corners on both sides of the packaging bag are filled first to prevent the bottom corners from being incompletely filled and wrinkles. At the same time, the motor 351 is started to reverse, and the worm 352 is engaged with the worm gear 362, and the traction belt 364 pulls the hanging rod 345 on the fixed ring 344, so that the two bend pipes 341 rotate synchronously inward with their respective pin shafts 342 as the rotation fulcrum. In this process, the movable bracket 39 is kept relatively small in height position change by the elastic force of the spring support rod 310, that is, the height position change of the two bend pipes 341 is not large, thereby providing sufficient time for the filling of the bottom corners on both sides of the packaging bag. Figure 12 As shown, when the blocking rod 343 outside the curved pipe 341 rotates to contact the movable bracket 39, the movable bracket 39 begins to move upward synchronously under the action of the tension force, overcoming the elastic force of the spring support rod 310, thereby causing the height of the two curved pipes 341 to rise as the bagging height increases, thereby preventing the lower ends of the two curved pipes 341 from being covered by rice and maintaining a small distance at the rice bagging height to reduce dust diffusion; When the motor 351 is rotating forward, the ratchet 353 squeezes the ratchet teeth 375, so that the ratchet teeth 375 compress the metal spring 376 without restricting the rotation of the ratchet 353. When the motor 351 is rotating backward, the ratchet teeth 375 are resisted by the supporting part 377 to lock the ratchet 353, so that the transmission plate 373 can rotate synchronously with the output shaft of the motor 351, and then drive the auger 372 outside the second transmission shaft 371 to spirally transport the rice in the collecting hopper 31 to the distribution bin 32 as a supplement, thereby realizing automatic feeding of the collecting hopper 31 into the distribution bin 32.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
