[0047] Among them, there may be 1 driving wheel 13, and it is preferably arranged at the central position of the driving shaft 111. The driving wheel 13 is located at the central position of the driving shaft 111, which can make the driving of the driving device 4 more stable, make the force on the driving shaft 111 uniform, and can better protect the driving shaft 111. Even if there is a situation of flipping and jamming, the chains on both sides of the hopper car 3 can evenly pull the hopper car 3 to descend and reset without manual operation, greatly improving the feeding efficiency.

[0048] In some embodiments, the upper sprocket 12 includes a bearing seat 1201. The upper sprocket 12 is fixedly connected to the track of the upper double guide rail 1 through the bearing seat 1201. Specifically, the bearing seat 1201 of the upper sprocket 12 is fixedly connected to the end of the driven shaft 121. More specifically, the bearing seat 1201 of the first upper sprocket is fixedly connected to the end of the driven shaft 121, and the bearing seat 1201 of the second upper sprocket is also fixedly connected to the end of the driven shaft 121. The structure of the lower sprocket 11 is the same as that of the upper sprocket 12, and may also include a bearing seat 1201, and is fixedly connected to the end of the driving shaft 111 through the bearing seat 1201.

[0049] In some embodiments, the double guide rail single-bucket elevator further includes a tensioning device 5. The tensioning device 5 is arranged on the driven shaft 121 and is connected to the bearing seat 1201.

[0050] With reference to Figure 4 , the tensioning device 5 includes a tensioning seat 51, a fixing block 52 and a tensioning block 53. The tensioning block 53 is arranged at one end of the tensioning seat 51 and fits with the upper sprocket 12. The tensioning seat 51 abuts against the tensioning block 53 through the fixing block 52. The tensioning seat 51 is connected to the upper sprocket 12, specifically connected to the bearing seat 1201 of the upper sprocket 12. And the tensioning block 53 can be located below the upper sprocket 12 and fit with the upper sprocket 12. That is, the tensioning block 53 fits with the upper sprocket 12 on one side and the chain on the other side. After the chain meshes with the upper sprocket 12, it contacts the tensioning block 53, and the tensioning block 53 can adjust and stretch the length of the chain, so as to tighten the chain and prevent the chain from sagging. Specifically, the tensioning block 53 can be located below the first upper sprocket and / or the second upper sprocket and fit with the first upper sprocket and / or the second upper sprocket. The tensioning seat 51 is connected to the bearing seat 1201 of the first upper sprocket and / or the second upper sprocket.

[0051] Specifically, the chain includes upper and lower sections, which are sleeved on the upper sprocket 12 and the lower sprocket 11 and enclose the upper sprocket 12 and the lower sprocket 11 therein.

By selecting the fixing block 52 to be connected to the tensioning seat 51 and abutting the selected fixing block 52 against the tensioning block 53, the included angle between the tensioning block 53 and the tensioning seat 51 can be adjusted, and then the chain can be stretched.

[0054] To further prevent the chain from sagging due to gravity, a tensioning sprocket 6 can be added to the sprocket assembly. In some embodiments, a first tensioning sprocket is provided on the first sprocket assembly. The first tensioning sprocket is located at the lower end of the first chain and meshes with the first chain; a second tensioning sprocket is provided on the second sprocket assembly. The second tensioning sprocket is located at the lower end of the second chain and meshes with the second chain; the second tensioning sprocket corresponds to the first tensioning sprocket. That is, the tensioning sprocket 6 is outside the loop of the chain, located at the lower end of the chain, and meshes with the chain.

[0055] There can also be two pairs or more than two pairs of tensioning sprockets 6. Among them, one pair is arranged inside the loop of the chain on the upper double guide rail 1 and meshes with the lower end of the chain; one pair is arranged outside the loop of the chain on the upper double guide rail 1 and meshes with the upper end of the chain.

[0056] Specifically, the combined use of the tensioning sprocket 6 and the tensioning device 5 can prevent the chain from sagging due to gravity and wobbling during operation, which may cause the chain to deviate from the sprocket, prevent the phenomenon of the hopper car 3 derailing, and at the same time avoid abnormal noises caused by collision with the guide rail and interference.

[0057] In some embodiments, the track of the lower double guide rail 2 includes an inclined section 21 and a bent section 22. The inclined section 21 is parallel to the track of the upper double guide rail 1; the bent section 22 is located at the top of the track and is in arc transition with the inclined section 21. The bent section 22 of the lower double guide rail 2 is used for the hopper car 3 to bend downward after the upper roller 32 of the hopper car 3 is lifted to the top of the track of the lower double guide rail 2, so as to facilitate the dumping of the material in the hopper car 3.

[0058] Specifically, the bent section 22 has a structure that bends downward, and the top of the bent section 22 is in arc transition with the top of the inclined section 21. Among them, the third track includes a first inclined section and a first bent section. The first inclined section is parallel to the first track of the upper double guide rail 1, and the first bent section is located at the top of the third guide rail and is in arc transition with the first inclined section; the fourth track includes a second inclined section and a second bent section. The second inclined section is parallel to the second track of the upper double guide rail 1, and the second bent section is located at the top of the fourth guide rail and is in arc transition with the second inclined section.

[0059] The material lifting and dumping process of the double-guide single-bucket elevator is as follows: After placing the material on the hopper car 3, the driving device 4 is started to drive the chain sleeved on the upper sprocket 12 and the lower sprocket 11 to rotate. The connecting sprocket 33 engaged with the chain is lifted as the chain rotates, pulling the lower rollers 31 at both ends of the lower optical axis 311 to move upward in the track of the upper double guide rail 1, and then driving the upper rollers 32 of the hopper car 3 to move upward in the track of the lower double guide rail 2, so that the hopper car 3 is steadily lifted along the upper double guide rail 1 and the lower double guide rail 2 based on the lower rollers 31 and the upper rollers 32 respectively. When the upper roller 32 moves to the top of the inclined section 21 and then moves downward along the bent section 22, the center of gravity of the hopper car 3 decreases as the upper roller 32 moves, causing the hopper car 3 to tilt and the material on the hopper car 3 to pour out.

[0060] The lowering process of the hopper car 3 after rising to the specified height is as follows: The driving device 4 drives the chain to move in the reverse direction. The connecting sprocket 33 engaged with the chain is lowered as the chain rotates, pulling the lower rollers 31 at both ends of the lower optical axis 311 to move downward in the upper double guide rail 1, and then driving the upper rollers 32 of the hopper car 3 to move downward in the lower double guide rail 2. The upper roller 32 moves upward along the bent section 22 to the top of the bent section 22 and then moves downward along the inclined section 21, so that the hopper car 3 steadily descends along the upper double guide rail 1 and the lower double guide rail 2 based on the lower rollers 31 and the upper rollers 32 respectively. In this process, under the uniform drive of the chains on both sides, the entire operation process of the hopper car 3 can be stable and quiet, avoiding the situation of jamming due to uneven force on one side.

[0061] Among them, both the upper roller 32 and the lower roller 31 of the hopper car 3 are supported by wear-resistant materials, which can be specifically polyurethane-coated bearing rollers; the polyurethane-coated bearing rollers are customized by coating the outer diameter of the bearing with polyurethane material, running smoothly and quietly in the guide rail, capable of withstanding large pressures, and having a longer service life.

[0062] In summary, the present application provides a double-guide single-bucket elevator. The hopper car is engaged with the first sprocket assembly and the second sprocket assembly, and the hopper car is driven to run on the upper double guide rail through the first sprocket assembly and the second sprocket assembly, so as to achieve the purpose of lifting the material on the hopper car; among them, the double-guide rail structure including the upper double guide rail and the lower double guide rail, the upper double guide rail not only provides a supporting role as a frame but also provides a guiding role as a guide rail, and the lower double guide rail mainly provides a guiding role as a guide rail. The two guide rails do not affect each other's work, but can stabilize the center of gravity position of the hopper car and avoid its running jamming; the hopper car is in rolling connection with the lower double guide rail, and is also in rolling connection with the first track and the second track, greatly improving the running stability of the hopper car.
