Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a mobile bulk material unloading and conveying device. Background Technology

[0002] A bulk material unloading and conveying device is used to unload bulk materials from transport vehicles or material silos. A typical bulk material unloading and conveying device includes a first conveyor belt and a second conveyor belt. The first conveyor belt is inclined, with its top end near the bulk material storage location. The second conveyor belt extends roughly horizontally, with its inlet end connecting to the bottom end of the first conveyor belt, and its outlet end near the unloading location. During unloading, the bulk material is poured onto the top end of the first conveyor belt, then slides downwards to the bottom end, and is subsequently conveyed to the unloading location by the second conveyor belt.

[0003] While existing bulk materials can be unloaded, they have the following drawbacks: the bulk material unloading and conveying device includes a first conveyor belt and a second conveyor belt, which are relatively long. In addition, the first conveyor belt is set at an incline and the second conveyor belt is set at a roughly horizontal position, resulting in a large overall volume. Consequently, when it is necessary to move the bulk material unloading and conveying device, the operation is troublesome, time-consuming, labor-intensive, and very inconvenient. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a mobile bulk material unloading and conveying device, which is simple to operate, saves time and effort, and is more convenient to move when the entire device needs to be moved.

[0005] According to an embodiment of the present invention, a mobile bulk material unloading and conveying device includes a first conveyor and a second conveyor. The first conveyor includes a first frame, a first conveyor belt, and an adjusting member. The first frame is provided with a plurality of first traveling wheels. The first conveyor belt is rotatably connected to the first frame. The rotation axis of the first conveyor belt extends along the width direction of the first conveyor belt. The first conveyor belt is provided with a sliding part that can slide along its own length direction, or the first frame is provided with a sliding part that can slide along its own length direction. The adjusting member is disposed between the first frame and the first conveyor belt to control the rotation of the first conveyor belt. The sliding part is connected to the second conveyor. The second conveyor is provided with a second conveyor belt and a plurality of second traveling wheels. When the adjusting member controls the first conveyor belt to rotate to a horizontal state, the sliding part can move the second conveyor to a first position and a second position by sliding. In the first position, the input end of the second conveyor belt is connected to the output end of the first conveyor belt. In the second position, the second conveyor is located inside the first frame.

[0006] The mobile bulk material unloading and conveying device according to embodiments of the present invention has at least the following beneficial effects:

[0007] When unloading is required, the walking bulk material unloading conveyor is moved to the corresponding position using the first and second traveling wheels. Then, the sliding adjustment part is slidable to position the second conveyor in the first position. In this case, the input end of the second conveyor belt is connected to the output end of the first conveyor belt. The adjusting component is then operated to control the first conveyor belt to rotate to an inclined state, bringing the top of the first conveyor belt close to the storage location of the bulk material. The bulk material can then be poured onto the top of the first conveyor belt, then slides downwards to the bottom of the first conveyor belt and falls onto the input end of the second conveyor belt, which then transports it to the unloading position. After unloading is completed, the adjusting component is operated to control the first conveyor belt to rotate to a horizontal state. The sliding adjustment part is then slidable to move the second conveyor to the second position within the first frame. In this case, the walking bulk material unloading conveyor is shorter overall, and the first conveyor belt is horizontally positioned, reducing the overall size of the walking bulk material unloading conveyor. Therefore, when moving the walking bulk material unloading conveyor, operation is simple, time-saving, labor-saving, and movement is more convenient.

[0036] The following is for reference. Figures 1 to 8 A mobile bulk material unloading and conveying device according to an embodiment of the present invention is described.

[0037] like Figures 1 to 5 As shown, the mobile bulk material unloading and conveying device according to an embodiment of the present invention includes a first conveyor 100 and a second conveyor 200.

[0038] For example, the first conveyor 100 includes a first frame 101, a first conveyor belt 102, and an adjusting member 103. The first frame 101 has a receiving cavity. The first frame 101 is provided with a plurality of first traveling wheels 104. Specifically, the first traveling wheels 104 can be mounted on a mounting part. The mounting part can be rotatably mounted on the first frame 101 around a vertical axis, thereby adjusting the traveling direction of the first traveling wheels 104 so that the first frame 101 can move in various directions. The first frame 101 can be moved manually, or the first traveling wheels 104 can be connected to a drive mechanism. The drive mechanism controls the rotation of the first traveling wheels 104, thereby driving the first frame 101 to move. The first conveyor belt 102 is rotatably connected to the first frame 101. The first conveyor belt 102 can be rotatably connected to the first frame 101 near the output end. The width direction of the first conveyor belt 102 can be parallel to the width direction of the first frame 101. The rotation axis of the first conveyor belt 102 extends along the width direction of the first conveyor belt 102. When the first conveyor belt 102 rotates to a horizontal state, the length direction of the first conveyor belt 102 can be parallel to the length direction of the first frame 101. The first conveyor belt 102 is provided with a sliding part 105 that can slide along the length direction of the first conveyor belt 102, or the first frame 101 is provided with a sliding part 105 that can slide along the length direction of the first frame 101. The adjusting member 103 is provided between the first frame 101 and the first conveyor belt 102 to control the rotation of the first conveyor belt 102.

[0039] The second conveyor 200 can be lower than the first conveyor belt 102. A sliding part 105 is connected to the second conveyor 200; specifically, the sliding part 105 can be connected to the input end of the second conveyor 200. The second conveyor 200 is equipped with a second conveyor belt 201 and multiple second traveling wheels 202. Specifically, the second traveling wheels 202 can be mounted on a mounting part that can rotate around a vertical axis on the second conveyor 200, thereby adjusting the traveling direction of the second traveling wheels 202 to facilitate movement of the second conveyor 200 in various directions. The second conveyor 200 can be moved manually, or the second traveling wheels 202 can be connected to a drive mechanism that controls the rotation of the second traveling wheels 202, thereby driving the second conveyor 200 to move.

[0040] When the adjusting member 103 controls the first conveyor belt 102 to rotate to a horizontal state, the sliding part 105 can move the second conveyor 200 to a first position and a second position through sliding. In the first position, the second conveyor 200 is mostly located outside the first conveyor 100, and the feed end of the second conveyor 200 is close to the output end of the first conveyor 100 and located below the output end of the first conveyor 100. As a result, the input end of the second conveyor belt 201 is just connected to the output end of the first conveyor belt 102. In the second position, the second conveyor 200 is located in the receiving cavity of the first frame 101.

[0041] In an embodiment of the present invention, when unloading is required, the walking bulk material unloading and conveying device is moved to the corresponding position by the first walking wheel 104 and the second walking wheel 202. Then, the sliding adjustment part 105 is slidably adjusted so that the second conveyor 200 is in the first position. In this case, the input end of the second conveyor belt 201 is connected to the output end of the first conveyor belt 102. Then, the adjustment member 103 is operated to control the first conveyor belt 102 to rotate to an inclined state, so that the top of the first conveyor belt 102 is close to the storage position of the bulk material. Then, the bulk material can be poured into the top of the first conveyor belt 102. Then, the bulk material slides downward to the bottom of the first conveyor belt 102 and falls to the input end of the second conveyor belt 201. Then, it is conveyed to the unloading position by the second conveyor belt 201. After unloading is completed, the operating adjustment component 103 controls the first conveyor belt 102 to rotate to a horizontal state. Then, the sliding adjustment component 105 is slidably adjusted, causing the second conveyor 200 to move to a second position within the first frame 101. In this case, the overall length of the walking bulk material unloading conveyor is shortened, and the first conveyor belt 102 is horizontally positioned, reducing the overall size of the walking bulk material unloading conveyor. Consequently, when the walking bulk material unloading conveyor needs to be moved, operation is simple, time-saving, labor-saving, and movement is more convenient. In addition, the first conveyor belt 102 can rotate around a horizontal axis, thereby adjusting the height of the input end of the first conveyor belt 102, making it suitable for bulk material storage positions at different heights, thus improving its practicality.

[0042] It should be noted that the adjusting component 103 can have various structures, such as a hydraulic cylinder or a pneumatic cylinder. Both the first conveyor belt 102 and the second conveyor belt 201 can include a support frame and a conveyor belt body mounted on the support frame. The sliding part 105 can be mounted on the first conveyor belt 102 or slidably mounted on the first frame 101; further details will not be provided here.

[0043] In some embodiments of the present invention, such as Figures 4 to 6As shown, the second conveyor 200 is provided with a first connecting part 203, and a second connecting part 204 is rotatably connected to the first connecting part 203. The rotation axis between the first connecting part 203 and the second connecting part 204 extends vertically. A sliding part 105 is connected to the second connecting part 204. The second conveyor 200 achieves rotation adjustment around the vertical axis through the relative rotation of the first connecting part 203 and the second connecting part 204. When the second conveyor 200 moves to the first position as the sliding part 105 slides, the first connecting part 203 rotates relative to the second connecting part 204, thereby allowing the second conveyor 200 to rotate and adjust around the vertical axis. This allows for adjustment of the conveying direction of the second conveyor 200, enabling the transport of bulk materials to different positions according to actual needs. Furthermore, when a large amount of material is unloaded at one position and there is insufficient space, the second conveyor 200 can be rotated and adjusted to unload the remaining bulk material to other positions.

[0044] It should be noted that after unloading is completed, the second conveyor 200 can be rotated and adjusted so that the length direction of the second conveyor belt 201 of the second conveyor 200 is parallel to the length direction of the first frame 101. Then, the first conveyor 100 can be easily moved into the first frame 101. There are several ways to rotate the first connecting part 203 and the second connecting part 204. For example, the bottom end of the second connecting part 204 may have a mounting hole, and the first connecting part 203 may be rotatably mounted in the mounting hole. Alternatively, the top end of the first connecting part 203 may have a mounting hole, and the second connecting part 204 may be rotatably mounted in the mounting hole.

[0045] In some embodiments of the present invention, such as Figure 4 and Figure 6 As shown, one of the first connecting part 203 and the second connecting part 204 is provided with a plurality of first positioning holes 205, and the other is provided with a plurality of second positioning holes 206. When the length direction of the second conveyor belt 201 is parallel to the length direction of the first frame 101, the first positioning holes 205 and the corresponding second positioning holes 206 are aligned to install fasteners and lock the first connecting part 203. After unloading is completed, the second conveyor 200 is rotated until the length direction of the second conveyor belt 201 is parallel to the length direction of the first frame 101. In this case, the first positioning hole 205 is aligned with the corresponding second positioning hole 206. Then, fasteners such as bolts or screws are installed in the first positioning hole 205 and the corresponding second positioning hole 206, which restricts the relative rotation of the first connecting part 203 and the second connecting part 204. This prevents the second conveyor 200 from rotating arbitrarily and keeps the second conveyor 200 in a state where the length direction of the second conveyor belt 201 is parallel to the length direction of the first frame 101, making it easier to move the second conveyor 200 into the first frame 101.

[0046] In some embodiments of the present invention, such as Figure 6 As shown, one of the first connecting part 203 and the second connecting part 204 is provided with a spring pin 207, and the other is provided with a recess 208. When the length direction of the second conveyor belt 201 is parallel to the length direction of the first frame 101, the spring pin 207 is engaged in the recess 208, so that the first positioning hole 205 and the corresponding second positioning hole 206 are kept in a centered state. After unloading is completed, the second conveyor 200 is rotated until the length direction of the second conveyor belt 201 is parallel to the length direction of the first frame 101. In this case, the spring pin 207 is just aligned with the recess 208, and the spring pin 207 can extend and slide into the recess 208, thereby causing a stop in the rotation of the second conveyor 200. The operator can then know that the first positioning hole 205 and the corresponding second positioning hole 206 are in a centered state, and then it is convenient for the operator to install bolts or screws and other fasteners into the first positioning hole 205 and the corresponding second positioning hole 206.

[0047] It should be noted that the spring pin 207 is a common elastic telescopic structure, which generally includes a mounting base, a spring on the mounting base, and an arc-shaped pin installed at the end of the spring. When the first positioning hole 205 is not aligned with the corresponding second positioning hole 206, the spring is compressed. When the first positioning hole 205 is aligned with the corresponding second positioning hole 206, the spring pin 207 is aligned with the recess 208, and the spring extends so that the arc-shaped pin is inserted into the recess 208.

[0048] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the sliding part 105 is slidably disposed on the first conveyor belt 102. The sliding part 105 is provided with a first connecting shaft 106, and the second connecting part 204 is provided with a second connecting shaft 209. Both the first connecting shaft 106 and the second connecting shaft 209 extend along the width direction of the first conveyor belt 102. The walking bulk material unloading conveyor also includes a connecting member 300. The connecting member 300 is provided with a sliding groove 301 that extends through both sides. The length direction of the sliding groove 301 is perpendicular to the axial direction of the first connecting shaft 106. Both the first connecting shaft 106 and the second connecting shaft 209 pass through the sliding groove 301 and can slide relative to the connecting member 300 along the length direction of the sliding groove 301. The sliding part 105 is slidably disposed on the first conveyor belt 102, which enables the second conveyor belt 201 of the second conveyor 200 to better connect with the first conveyor belt 102. With this configuration, the sliding part 105 will swing with the rotation of the first conveyor belt 102, while the first connecting part 203 and the second connecting part 204 are rotatably connected and cannot swing with the sliding part 105, which can easily lead to interference between the sliding part 105 and the first connecting part 203. In this embodiment, a connecting member 300 is provided, so that when the sliding part 105 swings with the rotation of the first conveyor belt 102, the first connecting shaft 106 and the second connecting shaft 209 can slide within the groove 301, thereby avoiding interference between the sliding part 105 and the first connecting part 203 and improving practicality.

[0049] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the sliding part 105 is slidably disposed on the first conveyor belt 102. The first conveyor belt 102 has third positioning holes 107 at both ends along its length. The sliding part 105 has a fourth positioning hole. When the second conveyor 200 is in the first and second positions, the fourth positioning hole aligns with the corresponding third positioning hole 107 to secure the sliding part 105 with fasteners. When the sliding part 105 slides to position the second conveyor 200 in the first position, the fourth positioning hole aligns with the corresponding third positioning hole 107. Fasteners are then installed in the fourth positioning hole and the corresponding third positioning hole 107 to prevent the second conveyor 200 from moving arbitrarily, thus improving the docking effect between the second conveyor belt 201 of the second conveyor 200 and the first conveyor belt 102 of the first conveyor 100. When the sliding part 105 slides to position the second conveyor 200 in the second position, the fourth positioning hole is aligned with the corresponding third positioning hole 107. Then, fasteners are installed in the fourth positioning hole and the corresponding third positioning hole 107 to prevent the second conveyor 200 from moving at will, thereby making the second conveyor 200 move better with the first conveyor 100.

[0050] In some embodiments of the present invention, such as Figures 1 to 3As shown, the second conveyor 200 also includes a second frame 210, with second traveling wheels 202 mounted on the second frame 210. Both the first frame 101 and the second frame 210 are equipped with retractable lifting mechanisms 400. During the extension and retraction of the lifting mechanism 400 on the first frame 101, it can be staggered with the first traveling wheel 104 to support the ground. Similarly, during the extension and retraction of the lifting mechanism 400 on the second frame 210, it can be staggered with the second traveling wheel 202 to support the ground. When the walking bulk material unloading and conveying device of the present invention is working, the lifting mechanism 400 extends, supporting the lifting mechanism 400 on the ground and separating the first traveling wheel 104 and the second traveling wheel 202 from the ground. This provides stable support for the first conveyor 100 and the second conveyor 200, preventing the walking bulk material unloading and conveying device from moving arbitrarily during operation, thereby improving the working effect. When the walking bulk material unloading and conveying device of the present invention needs to be moved, the lifting mechanism 400 is shortened so that the lifting mechanism 400, the first walking wheel 104 and the second walking wheel 202 can be supported on the ground, thereby facilitating the walking bulk material unloading and conveying device to move.

[0051] In some embodiments of the present invention, such as Figures 1 to 3 As shown, the second frame 210 includes two mounting brackets arranged side by side, each equipped with a lifting mechanism 400. The two ends of the second conveyor belt 201 are rotatably mounted on the two mounting brackets, and the axis of rotation of the second conveyor belt 201 extends along its width. When the lifting mechanisms 400 on the two mounting brackets extend or retract, the height of both ends of the second conveyor belt 201 can be adjusted, allowing the second conveyor belt 201 to be in a horizontal or inclined state according to actual conditions, thus improving its practicality.

[0052] In some embodiments of the present invention, such as Figure 7 and Figure 8As shown, the lifting mechanism 400 includes a sleeve 401, a sliding column 402, a lead screw 403, and a drive structure 404. The sleeve 401 extends vertically, the sliding column 402 is slidably installed vertically inside the sleeve 401, the lead screw 403 is vertically and rotatably installed inside the sleeve 401, the lead screw 403 is threadedly connected to the sliding column 402, and the drive structure 404 is located in the sleeve 401 and is connected to the lead screw 403 to control the rotation of the lead screw 403. Specifically, the sleeve 401 can be a square tube, and the sliding column 402 can be a square column. The outer wall of the sliding column 402 fits against the inner wall of the sleeve 401. The sliding column 402 is slidably installed inside the sleeve 401. The sliding column 402 has a vertical threaded hole, and the lead screw 403 is threadedly connected to the threaded hole. The lead screw 403 is controlled to rotate by the drive structure 404. Since the sliding column 402 cannot rotate with it, it can slide up and down. This allows the sliding column 402 to slide downwards and extend out of the sleeve 401 or slide upwards and be stored inside the sleeve 401, thereby realizing the extension and retraction of the lifting mechanism 400. The structure is simple and the operation is convenient.

[0053] It should be noted that the lifting mechanism 400 can also be other structures, such as a vertically arranged hydraulic cylinder.

[0054] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the drive structure 404 includes a drive shaft 405, a first bevel gear 406, a second bevel gear 407, and a handle 408. The drive shaft 405 is horizontally and rotatably mounted on the sleeve 401. The first bevel gear 406 is coaxially mounted on the drive shaft 405. The second bevel gear 407 is coaxially mounted on the top of the lead screw 403 and meshes with the first bevel gear 406. The handle 408 is connected to the drive shaft 405 to drive the drive shaft 405 to rotate. The rotation of the drive shaft 405 is controlled by the handle 408, and the rotation of the lead screw 403 is controlled by the meshing of the first bevel gear 406 and the second bevel gear 407. The structure is simple, and it is easy to operate manually, with low cost.

[0055] It should be noted that the lead screw 403 can also be rotated directly by the motor.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
