[0006] CN212387330U discloses a flowing type grain warehouse grain distribution system, which comprises a grain feeding device and a grain conveying and distribution device; the grain conveying and distribution device comprises a horizontal belt conveyor arranged on the top of the grain warehouse, a transverse grain distribution mechanism and a grain distribution mechanism; wherein the transverse grain distribution mechanism comprises a distribution frame slidably arranged on the grain warehouse, and a distribution pipe structure arranged on the distribution frame; the distribution pipe structure comprises a distribution pipeline with a plurality of discharge holes arranged on the distribution frame and connected with the grain distribution mechanism, and the distribution pipeline is inclinedly arranged from the top of the grain warehouse to the bottom of the grain warehouse. The above patent aims to solve the problem of traditional technology that a large amount of manpower and material resources are needed to level the grain in the grain warehouse, and the efficiency is low and the cost is high.

[0007] The above two patent documents both adopt horizontal sliding interception structure (the feeding warehouse of CN212449778U and the distribution frame of CN212387330U) to achieve the purpose of leveling the grain in the warehouse. However, due to the structural limitation, the way of intercepting grain is not only easy to damage the belt conveyor, but also difficult to intercept small grain. UTILITY MODEL CONTENT

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-7 A grain conveying and diverting device is applied to a belt conveyor 1, including a diverting box 2; a lower pressure roller 3 is provided below the diverting box 2; the diverting box 2 is provided with an inlet 201 and a diverting outlet 202; only the lower pressure roller 3 of the diverting box 2 contacts the belt a of the belt conveyor 1 and the contact is rolling.

[0034] When the belt conveyor 1 transports grain to the distribution box 2, the lower pressure roller 3 contacts and presses down on the belt a of the belt conveyor 1, so that the grain enters the distribution box 2 from the feed inlet 201 and is output from the distribution outlet 202.

[0035] In this design, the diversion box 2 serves to receive and output grain. The grain enters the interior of the diversion box 2 through the inlet 201 and is then output through the side outlet 202. Furthermore, in practical applications, the inlet 201 of the diversion box 2 is positioned lower than the conveying surface of the belt a to ensure that it can fully receive the grain conveyed by the belt a.

[0036] The grain conveying diversion device of this embodiment, when applied to the belt conveyor 1, can not only stably change the grain conveying direction, but also ensures that only the lower pressure roller 3 contacts the belt a of the belt conveyor 1 during the entire process, and the contact is rolling. Compared with the sliding contact of the previous material distribution structure, the rolling contact method adopted in this case can avoid damage to the belt a of the belt conveyor 1.

[0037] The diversion device in this embodiment also includes a lifting module 5; the diversion box 2 is mounted on the lifting module 5.

[0038] When the lifting module 5 drives the diversion box 2 to rise to a certain height, the diversion box 2 moves away from the belt a of the belt conveyor 1, and the belt conveyor 1 maintains horizontal transport of grain.

[0039] When the lifting module 5 drives the diversion box 2 to descend to a certain height, the lower pressure roller 3 contacts and presses down the belt a of the belt conveyor 1, so that the grain enters the diversion box 2 from the feed inlet 201 and is output from the feed outlet 202.

[0040] In this embodiment, the lower pressure roller 3 includes a first pressure roller 31 and a second pressure roller 32 respectively disposed on both sides of the diverter box 2. The length of the first pressure roller 31 and the second pressure roller 32 is not less than the width of the belt a, so as to ensure that the belt a can be pressed down stably without wrinkling, arching or folding.

[0041] In the above design, this embodiment uses the lower pressure roller 3 to press down the belt a, so that the belt a is in direct contact with the lower pressure roller 3. As the belt a continues to move, it will drive the first pressure roller 31 and the second pressure roller 32 to rotate. Compared with the traditional design that uses a scraper to intercept grain, this method can avoid damaging the belt a. It should be noted that in order to achieve the above action, the belt conveyor 1 should be equipped with a tensioning device to maintain the normal operation of the belt a.

[0042] In this embodiment, preferably, there are two distributing ports 202; the two distributing ports 202 are arranged opposite each other on one side of the diversion box 2. Under this preferred configuration, the design of two distributing ports 202 effectively improves the output efficiency of grain in the diversion box 2, thus enabling faster grain conveying. Of course, this embodiment does not limit the number and location of the distributing ports 202. Other preferred solutions for the number and location of the distributing ports 202 based on actual scenarios and requirements, as well as those skilled in the art, should also fall within the protection scope of this embodiment.

[0043] In this embodiment, more preferably, the diversion box 2 is provided with a guide surface inclined towards the dispensing port 202, so that the grain can be quickly output from the dispensing port 202. In this embodiment, the diversion box 2 is a rectangular parallelepiped, and a baffle 21 is provided inside, the surface of which is the guide surface; under this design, the interior of the diversion box 2 forms a cavity for receiving grain, and the grain in the cavity is guided out of the dispensing port 202 by the guide surface. In this embodiment, the guided grain is output vertically downwards, and the specific conveying direction is shown in the attached drawings. Of course, this embodiment does not limit the final output position of the grain.

[0044] Furthermore, it should be noted that this embodiment does not limit the number of lower pressure rollers 3 or the shape of the diversion box 2 in this solution. It is only necessary to ensure that the entire grain diversion device has only the lower pressure rollers 3 in rolling contact with the belt a of the belt conveyor.

[0045] In practical applications, multiple support rollers 4 are also included; the support rollers 4 are mounted on the belt conveyor 1; the diverter box 2 is positioned between two adjacent support rollers 4. Under the action of the support rollers 4, except for the area where the belt a is pressed down, the remaining area is unaffected and continues to transport grain in a stable state.

[0046] In this embodiment, specifically, the lifting module 5 includes a ball screw assembly 51 and a drive motor 52; the ball screw assembly 51 is mounted on the belt conveyor 1, and the movable end of the ball screw assembly 51 is connected to the diverter box 2; the drive motor 52 is used to control the diverter box 2 to rise or fall. More specifically, in this embodiment, there are four lifting modules 5; the diverter box 2 is mounted inside the belt conveyor 1 via the four lifting modules 5.

[0047] In this embodiment, four lifting modules 5 are respectively connected to one end of the first pressure roller 31 and the second pressure roller 32, thereby stably driving the flow divider 2 to press down. Of course, in other embodiments, one lifting module 5 can also drive the entire flow divider 2. In addition, this embodiment does not limit the type of lifting module 5. Under suitable conditions, it is also feasible to use a cylinder or a hydraulic cylinder.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
