[0004] CN212387330U discloses a flow-type grain distribution system for a granary, including a grain feeding device and a grain conveying and distributing device; the grain conveying and distributing device includes a horizontal grain conveyor belt arranged on the top of the granary, a transverse grain distributing mechanism and a grain distributing mechanism; wherein the transverse grain distributing mechanism includes a distributing frame slidably arranged on the granary, and a distributing pipe structure arranged on the distributing frame; the distributing pipe structure includes a distributing pipe with multiple feeding holes arranged on the distributing frame and connected to the grain distributing mechanism, and the distributing pipe is arranged to extend obliquely from the top of the granary to the bottom of the granary. The above patent aims to solve the problem that the leveling of grain in the granary in the traditional technology requires a lot of manpower and material resources, low efficiency and high cost.

[0005] Both of the above patent documents use a horizontally sliding interception structure (the feed bin of CN212449778U and the material distribution rack of CN212387330U) to achieve the purpose of leveling the grain in the granary. However, due to its structural limitations, it is not only single-purpose, but also the way of intercepting grain is not only easy to damage the grain conveyor belt, but also difficult to intercept grain with small particle size.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0046] Example 1

[0047] refer to Figures 1 to 9 A grain conveying device comprises a belt conveyor 1 and a plurality of grain conveying diverting devices, wherein the grain conveying diverting devices are arranged on the belt conveyor 1; the plurality of grain conveying diverting devices are arranged along the conveying direction of the belt conveyor 1 so that the grain is output from its set position;

[0048] The grain conveying and diverting device comprises a diverting box 2; a lower pressing roller 3 is arranged below the diverting box 2; the diverting box 2 is provided with a material inlet 201 and a material diverting port 202; only the lower pressing roller 3 of the diverting box 2 is in contact with the belt a of the belt conveyor 1 and is in rolling contact;

[0049] When the belt conveyor 1 conveys grains to the diverter box 2 , the pressing roller 3 contacts and presses down the belt a of the belt conveyor 1 , so that the grains enter the diverter box 2 from the feed inlet 201 and are output from the diverter box 2 .

[0050] The grain conveying equipment of this embodiment adopts a modular design. Without affecting the original structure of the belt conveyor 1, it is only necessary to add a grain conveying diversion device at a suitable position to output the grain transported by the belt conveyor 1 from a set position; in addition, the staff can arrange the grain conveying diversion device according to actual needs to achieve various transportation needs. It can be used for grain warehousing, screening, etc., which is of great significance for large-scale grain transportation.

[0051] In this design, the diverter box 2 plays the role of receiving and outputting grains. The grains enter the diverter box 2 from the inlet 201 and are then output from the side diverter port 202. In addition, in actual application, the inlet 201 of the diverter box 2 is arranged at a position lower than the conveying surface of the belt a so that it can fully receive the grains conveyed by the belt a.

[0052] The grain conveying diverting device of the present embodiment, when applied to the belt conveyor 1, can not only stably change the grain conveying direction, but also in the whole process, only the lower pressure roller 3 of the diverting device is in contact with the belt a of the belt conveyor 1 and is in rolling contact. Compared with the sliding contact of the previous material dividing structure, the rolling contact method adopted in this case can avoid damaging the belt a of the belt conveyor 1.

[0053] The flow diversion device of this embodiment further includes a lifting module 5; the flow diversion box 2 is arranged on the lifting module 5;

[0054] When the lifting module 5 drives the diverter box 2 to rise to a certain height, the diverter box 2 is away from the belt a of the belt conveyor 1, and the belt conveyor 1 keeps conveying the grain horizontally;

[0055] When the lifting module 5 drives the diverter box 2 to descend to a certain height, the pressing roller 3 contacts and presses down the belt a of the belt conveyor 1 , so that the grain enters the diverter box 2 from the feed inlet 201 and is output from the feed outlet 202 .

[0056] In this embodiment, the lower pressure roller 3 includes a first pressure roller 31 and a second pressure roller 32 respectively arranged on both sides of the diversion 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 to ensure that the belt a can be stably pressed down without wrinkling, arching or folding.

[0057] Under the above design, the present embodiment presses down the belt a through the lower pressing roller 3, and the belt a is in direct contact with the lower pressing roller 3. The belt a continues to move and drives the first pressing roller 31 and the second pressing roller 32 to rotate. Compared with the traditional design of intercepting grains with a scraper, this method can avoid damaging the belt a. It should be noted that in order to achieve the above action, a tensioning device should be provided on the belt conveyor 1 to maintain the normal operation of the belt a.

[0058] In this embodiment, preferably, there are two material distribution ports 202; the two material distribution ports 202 are relatively arranged on one side of the diverter box 2. Under this preference, the design of the two material distribution ports 202 effectively improves the output efficiency of grain in the diverter box 2 to adapt to faster grain transportation efficiency. Of course, this embodiment does not limit the number and position of the material distribution ports 202. Those skilled in the art may make other preferred solutions for the number and position of the material distribution ports 202 according to actual scenarios and requirements, which should also fall within the protection scope of this embodiment.

[0059] In this embodiment, it is further preferred that a guide surface inclined toward the distributing port 202 is provided in the diverter box 2, so that the grain can be quickly output from the distributing port 202. In this embodiment, the diverter box 2 is a rectangular parallelepiped as a whole, and a baffle 21 is provided inside the diverter box 2, and the surface of the baffle 21 is the guide surface; under this design, a cavity for receiving grain is formed inside the diverter box 2, and the grain in the cavity is guided and output toward the distributing port 202 through the guide surface. In this embodiment, the guided grain is output vertically downward, and the specific conveying direction is shown in the drawings of the specification. Of course, this embodiment does not limit the final output position of the grain.

[0060] In addition, it should be noted that this embodiment does not limit the number of the lower pressure rollers 3 and the shape of the diverter box 2 in this solution. It only needs to ensure that the entire grain diverter device has only the lower pressure roller 3 in rolling contact with the belt a of the belt conveyor.

[0061] In practical applications, a plurality of support rollers 4 are also included; the support rollers 4 are arranged on the belt conveyor 1; and the diverter box 2 is arranged 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 rest of the area is not affected, and the food is still transported in a stable state.

[0062] In this embodiment, the belt conveyor 1 is provided with a plurality of grooved rollers 6; the diverter box 2 is arranged between two adjacent grooved rollers 6. The grooved roller 6 is one of the key components of the belt conveyor 1, and is mainly used to maintain the smooth operation of the conveyor belt, prevent the belt a from running off, and form a certain guiding effect through the part in contact with the conveyor belt to ensure the conveying efficiency and accurate transmission of materials. Under the above position layout, when the diverter box 2 is fully pressed down, the belt a at the diverter box 2 is sunken downward, while the belts a on both sides of the diverter box 2 still maintain a horizontal conveying state, which has little effect on the movement of the belt a.

[0063] In this embodiment, specifically, the lifting module 5 includes a ball screw pair 51 and a drive motor 52; the ball screw pair 51 is arranged on the belt conveyor 1, and the movable end of the ball screw pair 51 is connected to the diverter box 2; the drive motor 52 is used to control the diverter box 2 to rise or fall. In this embodiment, more specifically, there are four lifting modules 5; the diverter box 2 is arranged in the belt conveyor 1 through the four lifting modules 5.

[0064] 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, so as to stably drive the diverter box 2 downward. Of course, in other embodiments, one lifting module 5 can also be used to drive the entire diverter box 2. In addition, this embodiment does not limit the type of lifting module 5. Under appropriate conditions, it is also feasible to use a cylinder or a hydraulic cylinder to achieve this.

[0065] Example 2

[0066] A grain conveying method, based on the grain conveying device described in Example 1, comprises the following steps:

[0067] Step 1: The belt conveyor 1 continuously and horizontally conveys grain;

[0068] Step 2: The lifting module 5 of any of the grain conveying and diverting devices drives the diverting box 2 to descend to a certain height, so that the lower pressing roller 3 contacts and presses down the belt a of the belt conveyor 1, thereby allowing the grain to enter the diverting box 2 from the feed inlet 201 and then be discharged from the diverting port 202;

[0069] Step 3: The lifting modules 5 of all the grain transporting and diverting devices drive the diverting boxes 2 to rise to a certain height, so that the diverting boxes 2 are away from the belt a of the belt conveyor 1, and the belt conveyor 1 resumes to transport grain horizontally.

[0070] In actual application, it also includes a control system, and the multiple grain transportation and diversion devices are all communicatively connected to the control system to realize various grain transportation scenarios.

[0071] Some application scenarios are provided below:

[0073] At this time, warehouse A, warehouse B, and warehouse C are respectively provided with grain conveying and diverting devices, and the corresponding grain conveying and diverting devices are connected to the corresponding warehouses through the discharge hopper 7; in actual application, the control system makes the grain conveying and diverting device of warehouse A work first according to the program setting, and its lifting module 5 drives the diverting box 2 and the lower pressure roller 3 to press down, so that the belt a there is concave downward, so that the feeding port 201 of the diverting box 2 can receive grain, and then input it into warehouse A through the diverting port 202 and the discharge hopper 7. Of course, the storage of quantitative grain can be realized in combination with the external sensor. When the storage volume of warehouse A reaches the requirement, the grain conveying and diverting device of warehouse A rises, and the grain conveying and diverting device of warehouse B presses down, and the storage of warehouse B is completed in the same way, and the same is true for warehouse C.

[0074] Scenario 2: Reference Figure 2 , transport grain to large warehouse D and make the grain level.

[0075] At this time, three grain conveying and diverting devices are arranged at a certain interval on the large warehouse D, and the three grain conveying and diverting devices are connected to the large warehouse D through the unloading hopper 7; the control method is similar to that of scene 1, except that the three grain conveying and diverting devices work in sequence, so that the grain falls from different positions of the large warehouse D.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
