Description

Technical Field

[0001] The invention relates to the technical field of material lifting, in particular to a chain plate type bucket elevator. Background Art

[0002] Bucket elevator is a conveying equipment used to continuously convey powdered, granular and small block materials in a vertical or nearly vertical direction. Its working principle is to scoop up the materials from the lower storage through a series of hoppers fixed on the traction chain or belt, lift them to the top with the conveyor belt or chain, bypass the top wheel and then flip downward to pour the materials into the receiving trough.

[0003] There are many types of bucket elevators available, which are mainly divided into three types: belt type, chain type and chain plate type according to the different traction devices. Among them, chain plate bucket elevators are widely used in building materials, chemical industry, mining, electric power and other industries because of their good sealing, convenient operation and maintenance and small footprint.

[0004] In the related art, for example, Chinese patent CN207209184U discloses a bucket elevator with a function of automatically raising the material height. When the bucket elevator with the function of automatically raising the material height is conveying rice, the rice is lifted up by the hopper so that the rice decreases in height, and the distance between the rice and the ultrasonic distance sensor increases, thereby exceeding the set value of the comparator. At this time, the power device is started to move the storage plate upward, thereby increasing the height of the rice, until the distance between the rice and the ultrasonic distance sensor is less than the set value of the comparator, the power device stops the storage plate from continuing to move, thereby keeping the height difference between the hopper and the rice unchanged, so that the hopper can carry more rice each time, thereby improving the conveying efficiency of the rice, and when the rice is conveyed, the vibrator is turned on to make the rice material at a higher place fall down, so that the rice material is more evenly distributed everywhere, which is convenient for being scooped up by the hopper.

[0005] Although the above-mentioned bucket elevator with the function of automatically raising the material height can ensure to a certain extent that the bucket can hold a sufficient amount of material every time it moves to the bottom, it is found in actual use that when the bucket moves to the top, most of the material inside it is mainly thrown out by centrifugal force, and a small part of the material cannot be thrown out due to its deep position, and can only fall back into the bucket elevator as the bucket flips, affecting the material conveying efficiency. Summary of the invention

[0006] Based on this, it is necessary to provide a chain plate bucket elevator to address the problem of low conveying efficiency in the current material lifting process.

[0009] Furthermore, the closing component includes a cover plate and a switching part, one end of the cover plate is elastically hinged to the top of the inner side of the hopper, and the other end is suspended. Under the elastic action, the cover plate has a tendency to open the opening of the hopper, and the cover plate has a corresponding first position and second position before and after rotation. When in the first position, the cover plate closes the opening of the hopper, and when in the second position, the cover plate opens the opening of the hopper; the switching part is configured to drive the cover plate to switch from the first position to the second position after the hopper receives material at the feed port, and drive the cover plate to switch from the second position to the first position when the hopper moves to the discharge port.

[0010] Further, the switching part includes a clamping strip and a clamping plate. The clamping strip is fixedly arranged at the top of the outer side of the hopper. The clamping plate is elastically and slidably inserted into the cover plate. Under the elastic action, the clamping plate has a tendency to protrude from the cover plate, and the clamping plate is configured to be capable of being clamped with the clamping strip. The closing mechanism further includes a first guiding part, a second guiding part and a third guiding part. The first guiding part is located above the feeding port and has a first inclined surface. The extending direction of the first inclined surface is the same as the inclined direction of the inclined pouring section and is in guiding cooperation with the clamping plate. The second guiding part and the third guiding part are arranged above the discharging port. The second guiding part is arranged above the third guiding part.

[0011] Further, the chain plate bucket elevator further includes an adjusting mechanism, and the adjusting mechanism is configured to be capable of adjusting the orientation when the cover plate opens the opening of the hopper so as to change the pouring direction of the material.

[0012] Further, the adjusting mechanism includes a vertical adjusting component and a horizontal adjusting component.

[0014] Further, the horizontal adjusting component includes a horizontally arranged second screw rod. One end of the second screw rod is threadedly connected to the slider, and the other end is rotatably arranged on the reversing sprocket.

[0017] Further, the chain plate bucket elevator further includes a tensioning mechanism configured to drive the driven sprocket to move in the vertical direction to tension the chain.

[0018] The beneficial effects of the present invention are as follows:

[0019] When the chain plate bucket elevator provided by the present invention is in use, first, the driving mechanism drives the driving sprocket to rotate. During the rotation of the driving sprocket, the driving sprocket synchronously drives the driven sprocket and the reversing sprocket to rotate through the chain, so that the chain forms a closed triangular conveying loop inside the casing, and further enables the hopper to move along the triangular conveying loop. During the movement of the hopper, materials are simultaneously fed into the casing through the feeding port. When the hopper moves in the vertical lifting section, the hopper first receives the materials fed from the feeding port, and then closes the opening under the action of the closing assembly to avoid material spilling during the lifting process. When the hopper switches from the vertical lifting section to the inclined discharging section, the hopper flips under the traction of the chain, so that the hopper opening faces downward, facilitating discharging. When the hopper moves in the inclined discharging section, the hopper opening is opened under the action of the closing assembly, and the materials inside the hopper can all be poured out under the action of gravity and discharged from the discharging port, which not only avoids the materials from falling back into the casing but also improves the conveying efficiency of the materials. When the hopper switches from the inclined return section to the vertical lifting section, the hopper flips under the traction of the chain, so that the hopper opening faces upward, facilitating material receiving. And since the hoppers filled with materials are distributed in both the vertical lifting section and the inclined discharging section, part of the energy required to lift the hopper in the vertical lifting section is converted from the gravitational potential energy of the hoppers in the inclined discharging section, which is beneficial to reducing the load of the driving mechanism and the use cost.

[0020] Further, by providing an adjusting mechanism, during use, the adjusting mechanism can adjust the orientation of the cover plate when opening the hopper opening, and while changing the dumping direction of the materials, it can also change the discharging direction of the materials from the discharging port, so as to adapt to the requirements of different material lifting heights and improve the versatility.

[0042] Specifically in this embodiment, Figure 1 As shown, the housing 1 is configured as a vertical box structure, the feed port 101 is opened on the left side wall of the housing 1, the discharge port 102 is opened on the right side wall of the housing 1, and the discharge port 102 is higher in the vertical direction than the feed port 101; Figure 2 As shown, the chain 11 is configured as an annular structure and is vertically inserted into the housing 1. There are two chains 11, which are spaced apart in the horizontal direction and are simultaneously transmission-sleeved on the outside of the driving sprocket 12, the driven sprocket 13 and the reversing sprocket 14.

[0043] There are two driving sprockets 12. The two driving sprockets 12 are coaxial and arranged at intervals in the horizontal direction, and are both inserted into the top of the machine housing 1. To facilitate the installation of the two driving sprockets 12, the chain plate bucket elevator is further provided with a first rotating shaft. The first rotating shaft is horizontally arranged at the top of the machine housing 1 and vertically penetrates the front and rear side walls of the machine housing 1 during installation. The two driving sprockets 12 are respectively fixedly sleeved at both ends of the first rotating shaft. There are two driven sprockets 13. The two driven sprockets 13 are coaxial and arranged at intervals in the horizontal direction, and are both inserted into the bottom of the machine housing 1. To facilitate the installation of the two driven sprockets 13, the chain plate bucket elevator is further provided with a second rotating shaft. The second rotating shaft is horizontally arranged at the bottom of the machine housing 1 and vertically penetrates the front and rear side walls of the machine housing 1 during installation. The axis of the second rotating shaft and the axis of the first rotating shaft are located in the same vertical plane. The two driven sprockets 13 are respectively fixedly sleeved at both ends of the second rotating shaft. The chain 11 between the driven sprocket 13 and the driving sprocket 12 is vertically arranged and is a vertical lifting section.

[0044] There are two reversing sprockets 14. The two reversing sprockets 14 are coaxial and inserted into the middle of the machine housing 1 and are located on the right side of the driving sprocket 12. To facilitate the installation of the two reversing sprockets 14, the chain plate bucket elevator is further provided with a third rotating shaft. The third rotating shaft is horizontally arranged in the middle of the machine housing 1 and vertically penetrates the front and rear side walls of the machine housing 1 during installation. The chain 11 between the driving sprocket 12 and the reversing sprocket 14 is inclined in the lower right direction and is an inclined discharging section. The chain 11 between the reversing sprocket 14 and the driven sprocket 13 is inclined in the lower left direction and is an inclined returning section.

[0045] As Figure 10 shown, the hopper 2 is arranged as a box structure with an open top. The cross-sectional shape of the hopper 2 is set as a rectangle, and the vertical cross-sectional shape is set as a U shape. To facilitate connecting the hopper 2 to the chain 11, the chain plate bucket elevator is further provided with multiple pairs of connecting blocks 21. A pair of connecting blocks 21 corresponds to one hopper 2 and two chains 11 at the same time. The two connecting blocks 21 of the same pair are symmetrically arranged on the left side wall of the hopper 2. The connecting block 21 is arranged as a U-shaped structure and is arranged on the left side wall of the hopper 2 with the opening facing right during installation. As Figure 3 shown, the other end of the connecting block 21 with opposite openings is fixedly sleeved on the chain 11.

[0046] During use, first, the driving mechanism 5 drives the driving sprocket 12 to rotate clockwise. During the process of the driving sprocket 12 rotating clockwise, the driving sprocket 12 synchronously drives the driven sprocket 13 and the reversing sprocket 14 to rotate clockwise through the chain 11, so that the chain 11 forms a closed triangular conveying loop inside the machine housing 1, and further enables the hopper 2 to move along the triangular conveying loop.

[0047] During the movement of the hopper 2, materials are simultaneously fed into the interior of the casing 1 through the feed inlet 101. When the hopper 2 moves in the vertical lifting section, the hopper 2 first receives the materials fed from the feed inlet 101, and then the opening is closed under the action of the closing assembly to avoid material spillage during the lifting process.

[0048] When the hopper 2 switches from the vertical lifting section to the inclined discharging section, the hopper 2 flips under the traction of the chain 11, so that the opening of the hopper 2 is set towards the lower right for convenient discharging.

[0049] When the hopper 2 moves in the inclined discharging section, the opening of the hopper 2 is opened under the action of the closing assembly. Under the action of gravity, all the materials inside the hopper 2 can be poured out and discharged from the discharge outlet 102. While preventing the materials from falling back into the interior of the casing 1, it is beneficial to improve the conveying efficiency of the materials.

[0050] When the hopper 2 switches from the inclined discharging section to the inclined returning section, the opening of the hopper 2 is set towards the lower left under the traction of the chain 11.

[0051] When the hopper 2 switches from the inclined returning section to the vertical lifting section, the hopper 2 flips under the traction of the chain 11, so that the opening of the hopper 2 is set upwards for convenient material receiving; and since the hoppers 2 filled with materials are simultaneously distributed in the vertical lifting section and the inclined discharging section, part of the energy required to lift the hopper 2 in the vertical lifting section is converted from the gravitational potential energy of the hopper 2 in the inclined discharging section, which is beneficial to reducing the load of the driving mechanism 5 and reducing the use cost.

[0052] In some embodiments, the closing assembly is provided to include a cover plate 31 and a switching part 32. One end of the cover plate 31 is elastically hinged to the top of the inner side of the hopper 2, and the other end is suspended. Under the elastic action, the cover plate 31 has a tendency to open the opening of the hopper 2. The cover plate 31 has corresponding first and second positions before and after rotation. When in the first position, the cover plate 31 closes the opening of the hopper 2, and when in the second position, the cover plate 31 opens the opening of the hopper 2; the switching part 32 is configured to drive the cover plate 31 to switch from the first position to the second position after the hopper 2 receives materials at the feed inlet 101, and drive the cover plate 31 to switch from the second position to the first position when the hopper 2 moves to the discharge outlet 102.

[0053] Specifically in this embodiment, as Figure 3 shown, the cover plate 31 is set as a plate-like structure with a rectangular shape, and is provided to include a mounting frame 311 and a sealing plate 312, as Figure 10As shown, the mounting frame 311 is set as a frame structure with a rectangular shape, and when installed, the left long side is hinged to the left top of the hopper 2, and the right long side is set to be suspended; the sealing plate 312 is set as a plate-like structure with a rectangular shape, and when installed, it covers the top of the mounting frame 311; to facilitate hinging the mounting frame 311 to the hopper 2, a rotating shaft 201 is arranged in parallel at the left top of the hopper 2. The rotating shaft 201 is set as a rotary body structure in the shape of a "work" character, and is set to include a fixed part in the shape of a "T" and a rotating part in the shape of a ring. The fixed part is fixedly arranged on the hopper 2 during installation, and the rotating part can be rotatably sleeved on the front end of the fixed part during installation. The left end of the front short side of the mounting frame 311 is fixedly sleeved on the rotating part during installation, and the left end of the rear short side can be rotatably sleeved on the rear end of the fixed part.

[0054] As Figure 3 shown, at this time, the cover plate 31 is in the first position, and the opening of the hopper 2 is open; as Figure 4 shown, at this time, the cover plate 31 is in the second position, and the opening of the hopper 2 is closed.

[0055] In a further embodiment, the switching part 32 is set to include a clamping strip 321 and a clamping plate 322. The clamping strip 321 is fixedly arranged on the top of the outer side of the hopper 2; the clamping plate 322 is elastically slidably inserted into the cover plate 31, and under the elastic action, the clamping plate 322 has a tendency to extend out of the cover plate 31, and the clamping plate 322 is configured to be able to be clamped with the clamping strip 321; the closing mechanism 3 is further set to include a first guiding part 16, a second guiding part 17 and a third guiding part 18. The first guiding part 16 is located above the feeding port 101 and has a first inclined surface 161. The extending direction of the first inclined surface 161 is the same as the inclined direction of the inclined pouring section, and is in guiding cooperation with the clamping plate 322; the second guiding part 17 and the third guiding part 18 are arranged above the discharging port 102. The second guiding part 17 is arranged above the third guiding part 18. The second guiding part 17 has a second inclined surface 171. The extending direction of the second inclined surface 171 is the same as the inclined direction of the inclined restoring section, and the second inclined surface 171 is in guiding cooperation with the clamping plate 322; the third guiding part 18 has a third inclined surface 181. The extending direction of the third inclined surface 181 is the same as the inclined direction of the inclined pouring section, and the third inclined surface 181 is in guiding cooperation with the clamping plate 322.

[0056] Specifically in this embodiment, as Figure 10As shown, the clamping strip 321 is set as a strip-shaped structure in the shape of "7", and is arranged parallel and fixed at the right top of the hopper 2 during installation. The bent section of the clamping strip 321 faces the rotating shaft 201; the clamping plate 322 is set as a plate-shaped structure in the shape of a rectangle, and is inserted into the mounting frame 311 during installation; to facilitate the support of the clamping plate 322, two guiding columns 3221 are vertically and symmetrically arranged on the front and rear side walls of the clamping plate 322 at the left end. The guiding column 3221 is set as a T-shaped structure, and the large end faces outward. Slide holes 3111 are opened in the middle of the two short side walls of the mounting frame 311. The clamping plate 322 is set such that the guiding column 3221 slides and is inserted into the slide hole 3111 during installation; to facilitate the elastic sliding of the clamping plate 322, a plurality of compression springs 34 are vertically and fixedly arranged on the right side wall of the left long side of the mounting frame 311. The plurality of compression springs 34 are arranged at intervals along the length direction of the mounting frame 311. The other ends of the compression springs 34 are all vertically and fixedly / abutted against the left side wall of the clamping plate 322. Under the action of the compression springs 34, the clamping plate 322 has a tendency to extend out of the cover plate 31; to facilitate the smoothness of the clamping between the clamping plate 322 and the clamping strip 321, the right side wall of the clamping plate 322 is set as an inclined surface, and the inclined surface extends along the lower left direction.

[0057] As Figure 2 and Figure 3 shown, the first guiding portion 16 is arranged on the rear inner wall surface of the housing 1. As Figure 7 shown, the first guiding portion 16 is set as a plate-shaped structure in the shape of a right trapezoid. The short bottom side and the long bottom side of the first guiding portion 16 both extend vertically, and the short bottom side is located on the left side of the long bottom side. The right-angled waist is horizontally arranged and is located above the inclined waist; the plane where the inclined waist is located is set as the first inclined surface 161.

[0058] Before receiving materials, the cover plate 31 is vertically arranged.

[0059] During the use process, when the hopper 2 moves to the first guiding portion 16, the guiding column 3221 first abuts against the first inclined surface 161. As the chain 11 moves, the hopper 2 moves upward relative to the first guiding portion 16. Under the pushing of the first inclined surface 161, the guiding column 3221 moves downward along the slide hole 3111. The guiding column 3221 synchronously drives the clamping plate 322 to retract into the cover plate 31, and the compression spring 34 is compressed; when the clamping plate 322 is completely retracted into the cover plate 31, under the continuous pushing of the first inclined surface 161, the guiding column 3221 drives the cover plate 31 to rotate counterclockwise around the rotating shaft 201 until the cover plate 31 is horizontally arranged; when the guiding column 3221 disengages from the first inclined surface 161, the compression spring 34 is released, and synchronously drives the clamping plate 322 to extend out of the cover plate 31 and be clamped on the clamping strip 321, realizing the sealing of the hopper 2.

[0060] As Figure 6 and Figure 9As shown in the figure, both the second guiding part 17 and the third guiding part 18 are arranged on the rear inner wall surface of the housing 1. The second guiding part 17 is located at the upper right of the third guiding part 18. The second guiding part 17 is arranged as a plate-like structure in the shape of a right trapezoid. The short bottom side and the long bottom side of the second guiding part 17 both extend vertically. The short bottom side is located on the left side of the long bottom side. The right-angle waist is horizontally arranged and is located below the inclined waist. The plane where the inclined waist is located is set as the second inclined surface 171. The third guiding part 18 is arranged as a plate-like structure in the shape of a pentagon, which is obtained by cutting off a corner from a rectangle. The inclined side of the third guiding part 18 is located at the upper right and extends obliquely in the lower right direction.

[0061] During the use process, when the hopper 2 moves to the second guiding part 17, the guiding column 3221 first abuts against the second inclined surface 171. As the chain 11 moves, the hopper 2 moves downward relative to the second guiding part 17. Under the pushing of the second inclined surface 171, the guiding column 3221 moves along the sliding hole 3111 in the direction away from the clamping strip 321. The guiding column 3221 synchronously drives the clamping plate 322 to retract into the cover plate 31. While making the clamping block disengage from the clamping connection with the clamping strip 321, the compression spring 34 is compressed. When the clamping plate 322 is completely retracted into the cover plate 31, under the action of the gravity of the material, the cover plate 31 has a tendency to rotate clockwise around the rotating shaft 201 to open the opening of the hopper 2. When the guiding column 3221 disengages from the second inclined surface 171, under the action of the gravity of the material, the cover plate 31 rotates clockwise around the rotating shaft 201 until it abuts against the third inclined surface 181. Under the action of the compression spring 34, the clamping plate 322 then extends out of the cover plate 31.

[0062] In a further embodiment, the height of the material lifted by the same elevator is often not adjustable and cannot adapt to complex working requirements. To solve this problem, the chain plate bucket elevator is further provided with an adjusting mechanism 4. The adjusting mechanism 4 is configured to be able to adjust the orientation of the cover plate 31 when opening the opening of the hopper 2, so as to change the dumping direction of the material.

[0063] During use, through the adjusting mechanism 4, the orientation of the cover plate 31 when opening the opening of the hopper 2 can be adjusted. While changing the dumping direction of the material, the discharging direction of the material from the discharge port 102 can be changed, so as to be able to adapt to the requirements of different material lifting heights and is beneficial to improving the versatility.

[0064] In a further embodiment, the adjusting mechanism 4 is arranged to include a vertical adjusting component 41 and a horizontal adjusting component 42. The vertical adjusting component 41 is configured to be able to adjust the position of the reversing sprocket 14 in the vertical direction. The horizontal adjusting component 42 is configured to be able to adjust the position of the reversing sprocket 14 in the horizontal direction.

[0065] Specifically in this embodiment, as Figure 6As shown, when the reversing sprocket 14 moves to the right, the angle between the vertical lifting section and the inclined discharging section increases, causing the rotation angle when the cover plate 31 opens to become larger, so as to be able to adapt to the discharging requirements at a lower height; similarly, when the reversing sprocket 14 moves to the left, the angle between the vertical lifting section and the inclined discharging section decreases, causing the rotation angle when the cover plate 31 opens to become smaller, so as to be able to adapt to the discharging requirements at a higher height.

[0066] When the reversing sprocket 14 moves upward, the angle between the vertical lifting section and the inclined discharging section increases, causing the rotation angle when the cover plate 31 opens to become larger, so as to be able to adapt to the discharging requirements at a lower height; similarly, when the reversing sprocket 14 moves downward, the angle between the vertical lifting section and the inclined discharging section decreases, causing the rotation angle when the cover plate 31 opens to become smaller, so as to be able to adapt to the discharging requirements at a higher height.

[0067] In a further embodiment, the vertical adjustment assembly 41 is arranged to include a vertically arranged first screw rod (not shown), one end of the first screw rod is threadedly connected to the machine housing 1, the other end is provided with a slider 411, and the reversing sprocket 14 is arranged on the slider 411.

[0068] Specifically in this embodiment, the first screw rod can be arranged outside the machine housing 1; as Figure 2 shown, one end of the slider 411 is slidably inserted into the machine housing 1, and the other end penetrates through the rear side wall of the machine housing 1; when installing the first screw rod, it can be arranged that the top end is fixedly connected to the bottom of the slider 411, and the bottom end is threadedly connected to the machine housing 1, and the second rotating shaft is rotatably arranged on the slider 411.

[0069] During use, the first screw rod can be rotated to drive the second rotating shaft to move up and down in the vertical direction through the slider 411, and the second rotating shaft synchronously drives the two reversing sprockets 14 to move up and down in the vertical direction.

[0070] In a further embodiment, the horizontal adjustment assembly 42 is arranged to include a horizontally arranged second screw rod 421, one end of the second screw rod 421 is threadedly connected to the slider 411, and the other end is rotatably arranged on the reversing sprocket 14.

[0071] Specifically in this embodiment, as Figure 2 shown, the left end of the second screw rod 421 is vertically and threadedly connected to the right side wall of the slider 411, and the right end is rotatably sleeved on the second rotating shaft.

[0072] During use, the second screw rod 421 can be rotated to drive the second rotating shaft to move left and right in the horizontal direction, and the second rotating shaft synchronously drives the two reversing sprockets 14 to move left and right in the horizontal direction.

[0073] In other embodiments, the closing component is further provided with an elastic member, which is connected to the hinge joint between the cover plate 31 and the hopper 2. Under the action of the elastic member, the cover plate 31 has a tendency to open the opening of the hopper 2.

[0074] Specifically in this embodiment, the elastic member is set as a torsion spring 33. As Figure 3 shown, when the torsion spring 33 is installed, it is sleeved on the rotating shaft 201, and the right end is fixedly arranged on the fixed part, and the left end is fixedly arranged on the rotating part. Under the action of the torsion spring 33, the cover plate 31 has a tendency to rotate clockwise around the rotating shaft 201.

[0075] In some other embodiments, the driving mechanism 5 is set to include a driving motor 51 and a speed reducer 52. The driving motor 51 and the speed reducer 52 are arranged outside the machine shell 1, and the input ends of the driving motor 51 and the speed reducer 52 are in transmission connection. The output end of the speed reducer 52 is in transmission connection with the driving sprocket 12.

[0076] Specifically in this embodiment, as Figure 1 shown, for the convenience of installing the driving mechanism 5, an installation platform 15 is fixedly sleeved on the outer side wall of the top of the machine shell 1. The installation platform 15 is horizontally arranged. When the driving motor 51 and the speed reducer 52 are installed, they are both fixedly connected to the top of the installation platform 15 by bolts.

[0077] During use, the driving motor 51 is started, and the driving motor 51 drives the driving sprocket 12 to rotate by itself through the speed reducer 52.

[0078] In some other embodiments, to improve the stability of the hopper 2 during movement, the chain plate bucket elevator is further provided with a tensioning mechanism 6. The tensioning mechanism 6 is configured to be able to drive the driven sprocket 13 to move in the vertical direction to tension the chain 11.

[0079] Specifically in this embodiment, sliding bearing seats are sleeved on both ends of the second rotating shaft outside the machine shell 1, and the sliding bearing seats can slide in the vertical direction; the tensioning mechanism 6 can be set to include a counterweight 61 and a sliding frame 62. The counterweight 61 is set as a strip structure and is horizontally penetrated through the front and rear side walls of the machine shell 1 during installation; the sliding frame 62 is set as a "C" - shaped structure and the opening faces downward. When the sliding frame 62 is installed, the two suspended ends are respectively vertically and fixedly arranged on the tops of the two sliding bearing seats. The counterweight 61 is arranged on the top of the sliding frame 62 during installation; to enable the counterweight 61 and the sliding frame 62 to slide in the vertical direction, as Figure 1 shown, vertical chutes 103 are penetrated through the front and rear side walls of the machine shell 1. The chutes 103 extend in the vertical direction. The counterweight 61 and the sliding block are simultaneously slidably inserted into the chutes 103.

[0080] During use, under the action of the gravity of the counterweight 61, the second rotating shaft has a tendency to move downward in the vertical direction, and the second rotating shaft has a tendency to tighten the chain 11 through the driven sprocket 13, so that the chain 11 can be tensioned.

[0081] It can be understood that the tensioning mechanism 6 can also be set as any one of the spiral tensioning device, the automatic compensation tensioning device or the screw tensioning device in the prior art.

[0082] Combined with the above embodiments, the working principle and process of the embodiments of the present invention are as follows:

[0083] During use, first rotate the first screw and the second screw 421 respectively according to the requirements of the discharging height. The first screw drives the second rotating shaft to move in the vertical direction through the second screw 421, and the second rotating shaft synchronously drives the two reversing sprockets 14 to move in the vertical direction; the second screw 421 drives the two reversing sprockets 14 to move in the horizontal direction through the second rotating shaft.

[0084] Then start the driving motor 51, and the driving motor 51 drives the driving sprocket 12 to rotate clockwise through the speed reducer 52; during the process of the driving sprocket 12 rotating clockwise, the driving sprocket 12 synchronously drives the driven sprocket 13 and the reversing sprocket 14 to rotate clockwise through the chain 11, so that the chain 11 forms a closed triangular conveying loop inside the machine housing 1, and further enables the hopper 2 to move along the triangular conveying loop.

[0085] During the movement of the hopper 2, materials are simultaneously fed into the machine housing 1 through the feeding port 101. When the hopper 2 moves in the vertical lifting section, the hopper 2 first receives the materials fed from the feeding port 101, and then moves to the first guiding portion 16; when the hopper 2 moves to the first guiding portion 16, the guiding column 3221 first abuts against the first inclined surface 161. As the chain 11 moves, the hopper 2 moves upward relative to the first guiding portion 16. Under the pushing of the first inclined surface 161, the guiding column 3221 moves downward along the sliding hole 3111, and the guiding column 3221 synchronously drives the clamping plate 322 to retract into the cover plate 31, and the compression spring 34 is compressed; when the clamping plate 322 is completely retracted into the cover plate 31, under the continuous pushing of the first inclined surface 161, the guiding column 3221 drives the cover plate 31 to rotate counterclockwise around the rotating shaft 201 until the cover plate 31 is horizontally arranged, and the torsion spring 33 stores energy; when the guiding column 3221 disengages from the first inclined surface 161, the compression spring 34 is released, and synchronously drives the clamping plate 322 to protrude from the cover plate 31 and be clamped on the clamping strip 321, realizing the sealing of the hopper 2.

[0086] When the hopper 2 switches from the vertical lifting section to the inclined discharging section, the hopper 2 is turned over under the traction of the chain 11, so that the opening is arranged towards the lower right, which is convenient for discharging.

[0087] When the hopper 2 moves in the inclined discharging section, when the hopper 2 moves to the second guiding part 17, the guiding column 3221 first abuts against the second inclined surface 171. As the chain 11 moves, the hopper 2 moves downward relative to the second guiding part 17. Under the pushing of the second inclined surface 171, the guiding column 3221 moves along the sliding hole 3111 in the direction away from the clamping strip 321. The guiding column 3221 synchronously drives the clamping plate 322 to retract into the cover plate 31. While the clamping block is disengaged from the clamping connection with the clamping strip 321, the compression spring 34 is compressed; when the clamping plate 322 is completely retracted into the cover plate 31, under the action of the gravity of the material and the elastic action of the torsion spring 33, the cover plate 31 has a tendency to rotate clockwise around the rotating shaft 201 to open the opening of the hopper 2; when the guiding column 3221 is disengaged from the second inclined surface 171, under the action of the gravity of the material and the elastic action of the torsion spring 33, the cover plate 31 rotates clockwise around the rotating shaft 201 until it abuts against the third inclined surface 181. At this time, the material pours out along the cover plate 31 and is discharged from the discharge port 102. At the same time, under the action of the compression spring 34, the clamping plate 322 synchronously extends out of the cover plate 31.

[0088] When the hopper 2 switches from the inclined discharging section to the inclined restoring section, under the traction of the chain 11, the opening of the hopper 2 is arranged towards the lower left, and the cover plate 31 is reset under the action of the torsion spring 33.

[0089] When the hopper 2 switches from the inclined restoring section to the vertical lifting section, under the traction of the chain 11, the hopper 2 turns over so that the opening is arranged upwards, which is convenient for receiving materials.

[0090] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0091] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
