Description

Technical Field

[0001] The utility model relates to the technical field of speed reducing devices, in particular to a speed reducing device for slowing down the flow rate of incoming grain in a building warehouse. Background Technique

[0002] During the process of grain entering and leaving the warehouse in bulk building warehouses, tall flat warehouses, shallow silos, vertical silos, semi-underground warehouses and underground warehouses, chute pipes are used to connect the equipment rooms, so that the grain can be safely stored.

[0003] In the utility model patent with the patent authorization announcement number CN216128753U, a material conveying speed reducer for a granary is disclosed, which includes an upper outlet pipe and a lower outlet pipe. A buffer area communicated with them is arranged between the upper outlet pipe and the lower outlet pipe. The buffer area is a multi-section buffer pipe with a buffer angle symmetrically arranged. The included angle between the first section of the buffer pipe and the horizontal direction is 36 - 60°, and the included angle between the end section and the horizontal direction is 26 - 60°. A flange one is arranged at the top of the upper outlet pipe, and a flange two is arranged at the bottom of the lower outlet pipe.

[0004] However, when only using the slope of the buffer pipe to buffer the transportation of grain, when too much grain needs to be transported and is poured in all at once from the feed inlet, blockage will occur at the pipe orifice. Moreover, when a large amount of grain is transported together, under the action of gravity and inertia, the grain will not be fully buffered and transported.

[0005] Therefore, we propose a speed reducing device for slowing down the flow rate of incoming grain in a building warehouse. Content of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art, and propose a speed reducing device for slowing down the flow rate of incoming grain in a building warehouse.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A speed reducing device for slowing down the flow rate of incoming grain in a building warehouse includes a feed pipeline, and diversion pipelines fixedly installed at both ends of the feed pipeline. Connecting boxes are fixedly installed on one side surface of both diversion pipelines. Holes are opened at one ends of the diversion pipelines in contact with the connecting boxes. Baffles are slidably installed inside both the connecting boxes and the diversion pipelines.

[0009] As a further scheme of the utility model: a hole groove is opened on one side surface of the diversion pipeline close to the feed pipeline, and the baffle is used to block the hole groove.

[0010] As a further scheme of the utility model: a device box is fixedly installed at one end of the connecting box away from the diversion pipeline, and a support plate is fixedly installed inside the device box.

[0011] As a further solution of the present utility model: a driving device is fixedly installed on one side surface of the support plate, a threaded rod is fixedly installed at the output end of the driving device, and the threaded rod penetrates through the support plate.

[0012] As a further solution of the present utility model: a guide rod is fixedly installed on one side surface of the support plate, the guide rod penetrates through the support plate, an L-shaped plate is fixedly installed on the upper surface of the baffle, the threaded rod is in threaded connection with the L-shaped plate, and the guide rod is slidably connected with the L-shaped plate.

[0013] As a further solution of the present utility model: limiting holes are formed on the upper surface of the connection box and the lower surface of the device box, and the threaded rod and the guide rod extend into the connection box.

[0014] Compared with the prior art, the present utility model provides a speed reduction device for slowing down the flow rate of incoming grain in a building warehouse, and has the following beneficial effects:

[0015] In the present utility model, when the staff pours the grain through the feeding pipe, the grain will flow towards the two diversion pipes, further solving the problem of blockage at the feeding port. By forming holes on the bottom of the connection box and one side surface of the diversion pipe, the baffle can slide inside the connection box and inside the diversion pipe. When the staff controls the driving device to make the baffle slide, the holes formed on the diversion pipe can be blocked. Thus, the cooperation of the baffle and the holes can control the quantity of the discharged material, and further control the flow rate of the falling grain, so that the grain has a buffer when falling.

[0016] In the present utility model, when the threaded rod rotates, it drives the L-shaped plate to move vertically, and then drives the baffle to move vertically. Thus, the baffle can block the holes. At the same time, the guide rod is slidably connected with the L-shaped plate, so that when the L-shaped plate moves vertically, it is more stable.

[0017] Parts not involved in this device are the same as or can be implemented by using the prior art. The structure of the present utility model is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0025] Embodiment: A flow rate reducing device for grain intake in a building warehouse, as Figure 1 - Figure 4 shown, includes a feed pipe 1 and shunt pipes 2 fixedly installed at both ends of the feed pipe 1. Connection boxes 3 are fixedly installed on one side surface of both shunt pipes 2. Holes 11 are opened at one end of the shunt pipe 2 in contact with the connection box 3. Baffles 5 are slidably installed inside both the connection box 3 and the shunt pipe 2. By providing the shunt pipe 2, and the staff can manually connect and install the shunt pipe 2 with other buffer pipes to further slow down the flow rate of the grain intake in the building warehouse. By providing the feed pipe 1 and the shunt pipes 2, when the staff pours the grain into the feed pipe 1, the grain will flow into the two shunt pipes 2, further solving the problem of blockage at the feed port. By opening holes 11 on the bottom of the connection box 3 and one side surface of the shunt pipe 2, the baffle 5 can slide inside the connection box 3 and inside the shunt pipe 2. When the staff controls the driving device to make the baffle 5 slide, the slot 12 opened on the shunt pipe 2 can be blocked, so that the cooperation of the baffle 5 and the slot 12 can control the quantity of the discharged material, thereby controlling the flow rate of the falling grain, and then making the grain have a buffer when falling.

[0026] As Figure 1 - Figure 4 shown, on the surface of the diversion pipeline 2 near the feed pipeline 1, there is a hole groove 12. The baffle 5 is used to block the hole groove 12. At one end of the connection box 3 away from the diversion pipeline 2, a device box 4 is fixedly installed. Inside the device box 4, a support plate 9 is fixedly installed. By setting the hole groove 12, when the baffle 5 does not block the hole groove 12, the grains poured from the feed pipeline 1 will enter the inside of the diversion pipeline 2 through the hole groove 12. If one of the baffles 5 blocks the hole groove 12, the grains poured from the feed pipeline 1 will enter the inside of the diversion pipeline 2 through the unblocked hole groove 12. Thus, the staff can control the flow direction of the grains and avoid blockage. By setting the device box 4 and installing a driving device inside the device box 4, the device box 4 can protect the driving device inside it.

[0027] As Figure 1 - Figure 4 shown, on one side surface of the support plate 9, a driving device 7 is fixedly installed. At the output end of the driving device 7, a threaded rod 6 is fixedly installed. The threaded rod 6 penetrates through the support plate 9. On one side surface of the support plate 9, a guide rod 8 is fixedly installed. The guide rod 8 penetrates through the support plate 9. By setting the driving device 7 and fixedly installing the threaded rod 6 at the output end of the driving device 7, and at the same time, the threaded rod 6 is rotatably connected to the support plate 9. When the staff turns on the driving device 7, it drives the threaded rod 6 to rotate.

[0028] As Figure 1 - Figure 4 shown, on the upper surface of the baffle 5, an L-shaped plate 13 is fixedly installed. The threaded rod 6 is threadedly engaged with the L-shaped plate 13. The guide rod 8 is slidably connected to the L-shaped plate 13. On the upper surface of the connection box 3 and the lower surface of the device box 4, limit holes 10 are opened. The threaded rod 6 and the guide rod 8 extend into the connection box 3. By setting the threaded rod 6 to be threadedly engaged with the L-shaped plate 13 and the L-shaped plate 13 being fixedly connected to the baffle 5, when the threaded rod 6 rotates, it drives the L-shaped plate 13 to move vertically, and then drives the baffle 5 to move vertically, so that the baffle 5 can block the hole groove 12. At the same time, the guide rod 8 is slidably connected to the L-shaped plate 13, so that when the L-shaped plate 13 moves vertically, it is more stable. By setting the limit holes 10, the threaded rod 6 and the guide rod 8 can extend into the connection box 3, and the L-shaped plate 13 and the baffle 5 can slide into the device box 4. Thus, when the hole groove 12 is not blocked by the baffle 5, and the staff can control the switch and usage time of the driving device 7, and then control the moving time of the baffle 5, and then can control the area of the hole groove 12 blocked by the baffle 5, so as to control the flow rate of the grains.

[0029] Working principle: When the staff pour the grain into the feeding pipe 1, the grain will flow towards the two shunt pipes 2. When the staff turn on the driving device 7, it drives the threaded rod 6 to rotate, drives the L-shaped plate 13 to move vertically, and then drives the baffle 5 to move vertically, so that the baffle 5 can block the hole slot 12. At the same time, the guide rod 8 is slidably connected to the L-shaped plate 13, so that when the L-shaped plate 13 moves vertically, it is more stable. At the same time, the staff can control the switch and usage time of the driving device 7, and then control the moving time of the baffle 5, and then can control the area of the hole slot 12 blocked by the baffle 5, so as to control the flow rate of the grain.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
