Description

Technical Field

[0001] The utility model belongs to the technical field of buffer equipment, in particular to an anti-breakage flow pipe buffer device. Background Art

[0002] After being husked, the rice loses the protection of the husk. When the rice is fed into the rice storage box through the elevator hopper, the rice will fall directly from the top of the rice storage box to the bottom of the rice storage box. The rice grains fall from a high place and come into contact with mechanical equipment, causing the rice grains to be subjected to a large impact force when falling, causing the rice to break due to the impact, and the broken rice rate is high.

[0003] In the related art, a search revealed a scheme for an anti-breakage buffer device for rice processing (Announcement No. CN208616826U), which changes the inclination angle of the first buffer plate through the elastic deformation of the support spring, thereby changing the sliding speed of the rice. In addition, the limit block can limit the inclination angle of the first buffer plate, thereby limiting the sliding speed of the rice, protecting the rice, reducing the broken rice rate during rice processing, and increasing the service life of the equipment without affecting the quality of the rice. However, when rice enters this buffer device, it will hit the buffer plate multiple times during the falling process, causing the rice to be subjected to excessive collision and still easily broken. Summary of the Invention

[0004] The purpose of the utility model is to provide an anti-breakage flow pipe buffer device to solve the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an anti-breakage flow pipe buffer device, comprising a base and a top plate, wherein the top plate is arranged above the base, and a lifting mechanism is connected to the upper side of the base.

[0006] A connecting plate is welded to the front side of the top plate, a bearing is fixedly connected to the inside of the connecting plate, a spiral pipe is installed on the inside of the bearing, a feed hopper is welded to the upper end of the spiral pipe, the lower end of the discharge pipe is connected to the discharge pipe, the upper side of the discharge pipe is fixedly connected to an arc plate, a sealing plate is slidably connected to the inside of the spiral pipe, a rotating rod is welded to the upper end of the outer side of the sealing plate, a first driven gear is installed on the outer side of the upper end of the rotating rod, a round rod is connected to the inside of the connecting plate, a rotating handle is welded to the upper end of the round rod, and the lower end of the round rod is fixedly connected to the first driving gear.

[0007] Preferably, the feed pipes are fixed to the same vertical direction inside the spiral pipe at equal distances, and the arc-shaped plate is fixed to the upper rear end of the feed pipe.

[0008] Preferably, a sliding hole is opened at one inner end of the connecting plate, and the outer side of the round rod is slidably connected to the inner side of the sliding hole.

[0009] Preferably, the first driven gear is meshed with the first driving gear.

[0010] Preferably, the lifting mechanism includes a threaded barrel, which is fixedly connected to the upper side of the base, and is welded to the front and rear ends of the outer side of the threaded barrel. The lower side of the top plate is connected to a threaded rod, and limiting rods are welded to the front and rear ends of the threaded rod on the lower side of the top plate, and a first motor is installed on the upper side of the top plate.

[0011] Preferably, the lower end of the output shaft of the first motor is fixedly connected to the upper end of the threaded rod, the outer side of the limiting rod is slidingly connected to the inner side of the cylinder, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded cylinder.

[0012] Preferably, a second motor is installed at the upper front end of the top plate, the lower end of the output shaft of the second motor is fixedly connected to a second driving gear, the outer side of the upper end of the spiral pipe is fixedly connected to a second driven gear, and the second driving gear and the second driven gear are meshed.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] The anti-breakage flow pipe buffer device moves the spiral pipe to the inside of the rice filling box, then fills the rice from the feed hopper into the spiral pipe and then slides down the inner side of the spiral pipe. The sliding of the spiral can buffer the sliding rice, so that the rice slides out of the spiral pipe at a low speed and does not break. When the rice in the box submerges the bottom end of the spiral pipe or one of the discharge pipes, the first driving gear is moved to the outer end of the first driven gear at the upper end of the discharge pipe to engage with it. Then, the rotating handle is rotated to rotate the first driving gear and drive the sealing plate to rotate to close the front end of the discharge pipe, so that the rice does not slide down further. The rice is discharged from the discharge pipe, which can prevent a large amount of rice from accumulating in the spiral pipe during the filling process. At this time, the distance the rice falls from the discharge pipe to the rice pile is short, so the impact force when falling is small and the rice is not easily broken.

[0015] The anti-breakage flow pipe buffer device is configured such that after rice filling is completed, the first motor is started to rotate its output shaft, driving the threaded rod to rotate, causing the threaded rod located inside the threaded barrel to rotate and move upward, driving the top plate and the spiral pipe at the front end to move upward together. Simultaneously, the second motor is started to rotate the second driving gear, driving the second driven gear to rotate, causing the spiral pipe to move upward and rotate along its own thread direction. In this way, when the spiral pipe is removed from a box filled with rice, the rice is not excessively squeezed and thus broken. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0029] To solve the problem that the rice will hit the buffer plate multiple times during the falling process, causing the rice to be hit too hard and still easily broken, please refer to Figures 1 to 6 As shown, an anti-breakage flow pipe buffer device, in this embodiment, includes a base 1 and a top plate 2, the top plate 2 is arranged above the base 1, and a lifting mechanism is connected between the base 1 and the top plate 2, which is used to place the spiral pipe 303 at the front end into the rice filling box.

[0030] A connecting plate 301 is welded to the front side of the top plate 2, and a bearing 302 is fixedly connected to the inside of the connecting plate 301, and a spiral pipe 303 is installed on the inner side of the bearing 302. A feed hopper 304 is welded to the upper end of the spiral pipe 303, and a discharge pipe 305 is connected to the lower end of the discharge pipe 305. The upper side of the discharge pipe 305 is fixedly connected to an arc plate 306. The discharge pipe 305 is fixed to the same vertical direction inside the spiral pipe 303 at equal distances, and the arc plate 306 is fixed to the upper rear end of the discharge pipe 305, so that the rice after entering the feed hopper 304 will flow into the spiral pipe 303, rotate and slide down along the inner side of the spiral pipe 303, and at the same time play a buffering role for the rice, and when the rice moves above the discharge pipe 305, it is blocked by the arc plate 306 and slides to both sides, and will not fall into the discharge pipe 305.

[0031] A sealing plate 307 is slidably connected to the inside of the spiral pipe 303. A rubber pad is fixedly connected to the outside of the sealing plate 307. When the sealing plate 307 is rotated to close the spiral pipe 303, the rubber pad on the outside of the sealing plate 307 contacts the inside of the spiral pipe 303, thereby maintaining a seal. A rotating rod 308 is welded to the upper end of the outer side of the sealing plate 307. A first driven gear 309 is mounted on the outer side of the upper end of the rotating rod 308. A round rod 311 is connected to the inside of the connecting plate 301. A rotating handle 310 is welded to the upper end of the round rod 311, and the lower end of the round rod 311 is fixedly connected to the first driving gear 312. A sliding hole is formed at one end of the connecting plate 301. The outer side of the round rod 311 is slidably connected to the inner side of the sliding hole. As a result, when the rotating handle 310 is pulled, the round rod 311 slides along the inner side of the sliding hole, driving the first driving gear 312 to move to different height positions.

[0032] The first driven gear 309 is meshed with the first driving gear 312. When the round rod 311 moves to move the first driving gear 312 to mesh with the first driven gear 309, the rotating handle 310 is rotated to rotate the first driving gear 312, thereby driving the first driven gear 309 to rotate, thereby rotating the rotating rod 308 and driving the sealing plate 307 to rotate together.

[0033] The lifting mechanism includes a threaded barrel 401, which is fixedly connected to the upper side of the base 1 and welded to the front and rear ends of the outer side of the threaded barrel 401. A threaded rod 403 is connected to the lower side of the top plate 2. A limiting rod 404 is welded to the front and rear ends of the threaded rod 403 on the lower side of the top plate 2. A first motor 405 is installed at the upper rear end of the top plate 2. The lower end of the output shaft of the first motor 405 is fixedly connected to the upper end of the threaded rod 403. The outer side of the limiting rod 404 is slidably connected to the inner side of the cylinder 402. The outer side of the threaded rod 403 is threadedly connected to the inner side of the threaded barrel 401. When the first motor 405 is started and its output shaft rotates, the threaded rod 403 located inside the threaded barrel 401 rotates, which can cause the threaded rod 403 to move relative to the threaded barrel 401. At the same time, the limiting rod 404 slides in the cylinder 402, causing the top plate 2 at the upper end to move while driving the spiral pipe 303 at the front end to move together.

[0034] A second motor 5 is mounted on the upper front end of the top plate 2. A second driving gear 6 is fixedly connected to the lower end of the output shaft of the second motor 5. A second driven gear 7 is fixedly connected to the outer side of the upper end of the spiral pipe 303. The second driving gear 6 and the second driven gear 7 are meshed. By starting the second motor 5, the second driving gear 6 rotates, driving the second driven gear 7, which in turn rotates the spiral pipe 303 and simultaneously lifts it. This ensures that the lifting of the spiral pipe 303 does not excessively squeeze the rice inside the filling box, preventing the filled rice from breaking.

[0035] The first motor 405 and the second motor 5 are both conventional instruments. Their working principles, sizes and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] Working principle: When filling rice, the anti-breakage flow pipe buffer device first places the box to be filled with rice under the spiral pipe 303, then starts the first motor 405, and its output shaft rotates to drive the threaded rod 403 to rotate and move downward until the spiral pipe 303 at the front end is driven to move into the interior of the box. After that, the first motor 405 is turned off, and the rice is filled into the feed hopper 304. Then the rice enters the spiral pipe 303 and slides down along the inner side of the spiral pipe 303 until it slides out from the lower end to the bottom end of the box. Then, as the rice accumulates inside the box, when the bottom of the spiral pipe 303 or one of the discharge pipes 305 is submerged, the sealing plate 307 at the upper end of the discharge pipe 305 is rotated to close the inner side of the spiral pipe 303, so that the rice falls from the discharge pipe 305 above the rice pile until the rice is completely filled and the spiral pipe 303 is taken out of the box.
