Description

Technical Field

[0001] This utility model relates to the technical field of mining machinery and equipment, specifically to an adjustable conveying device and a material crusher having the same. Background Technology

[0002] Crushers are mainly used in the crushing of materials such as coal, and can also crush other materials such as ore, slag, and rock. Taking coal as an example, after crushing, the coal is screened by a screen mechanism to obtain finer coal. Existing coal crushing systems generally include a frame, power system, crushing section, screening section, hopper, and conveying section. The frame is equipped with wheels. The screening section performs preliminary screening of the material conveyed from the hopper. The crushing section is used to crush the material. The conveying section receives the crushed material and transports it to the outside. The conveying section is located below the screening section and the crushing section. Crushers generally operate continuously during the crushing process, with a continuous supply of material and continuous output after crushing. Therefore, a large amount of material accumulates at the discharge port at the end of the crusher. If it is not transferred or disposed of in time, it may cause accumulation and affect the crushing operation. Existing crushers have a conveying section at the bottom for receiving the crushed material. This section generally uses a conveyor belt to transfer the material; that is, a conveyor belt is installed below the screening section and the crushing section to transfer the material out. To facilitate the transport of crushed materials to distant locations, conveyor belts are typically lengthened and inclined. However, excessively long or inclined conveyor belts can interfere with the setup and operation of other crushing components, such as the crushing and screening sections. Furthermore, these extended conveyor belts are usually fixed to the crusher, preventing relative deflection and severely limiting operational methods and efficiency. Alternatively, additional transfer machinery such as loaders can be used to transport materials to distant locations. While loaders are a better choice for distances far exceeding the material pile, they significantly increase equipment, labor, and energy costs for distances near the pile. The coordination between various large pieces of equipment also impacts work efficiency. Summary of the Invention

The crushing system is used to crush the raw materials. The discharging device is used to receive the material processed by the crushing system and convey the material to the conveying device located at the end of the frame. The conveying device receives the material fed by the discharge device and lifts and transports the material to a distant location.

[0012] The discharge device includes a second conveyor belt, which is located at the bottom of the crushing system.

Detailed Implementation

[0022] First embodiment: like Figure 1 As shown, the adjustable conveying device is mounted on the crusher at its tail end. The two devices work together to perform secondary lifting and long-distance conveying of the crushed material, thereby improving stockpiling efficiency. Alternatively, this adjustable conveying device can be integrated into a standalone unit and mounted on different types of crushers.

[0023] by Figure 1Taking the conveying device and crusher shown as an example, the conveying device includes a support base, a turntable, and a first conveyor belt. The support base is located at the tail of the crusher and is used to support and assemble the first conveyor belt and the turntable. The support base is fixedly connected to the crusher or integrally formed, or designed as a detachable structure for easy movement or replacement. The turntable is used to establish a movable connection between the first conveyor belt and the support base. The bottom of the turntable is rotatably connected to the support base, and the top of the turntable is provided with a support ear for assembling and connecting the first conveyor belt. A vertical adjustment device is provided between the first conveyor belt and the crusher to adjust the vertical tilt angle of the first conveyor belt. A horizontal adjustment device is provided between the turntable and the crusher to adjust the horizontal swing angle of the turntable and the first conveyor belt. The vertical adjustment device and the horizontal adjustment device are provided simultaneously, or only one of them is provided.

[0024] A conventional crusher includes a frame, power system, transmission system, crushing system, feeding device, discharging device, and conveying device. The frame provides a support platform and assembly base for the power system, transmission system, crushing system, feeding device, and discharging device. The power system, located at the front of the frame, provides power to all components, devices, and functional systems of the crusher. This power source can be a single type, a composite type, or a composite power source converted through methods such as oil-to-electricity conversion or electromagnetic conversion. The transmission system establishes the transmission connection between the power system and the crushing system, feeding device, and discharging device. These transmission methods include, but are not limited to, hydraulic devices, pneumatic devices, gear transmission devices, chain transmission devices, etc., which will not be elaborated further. The feeding device is located on the upper part of the frame and is used to convey raw materials to the crushing system. The crushing system is used to crush the raw materials. According to the different crushing principles of the crushers, they include jaw crushers, cone crushers, impact crushers, hammer crushers, double roll crushers, etc. After the raw materials are crushed, the discharge device is used to receive the material processed by the crushing system and convey the material to the conveying device located at the end of the frame. The conveying device receives the material fed by the discharge device and lifts and conveys the material to the far end.

[0025] Conventional crushers are limited by the overall height and length requirements of the machine, resulting in relatively short conveyor systems with limited capacity to transport materials to distant locations. Furthermore, the conveyor system is typically mounted at the bottom of the feeding device and crushing system, severely restricting its tilt angle and further limiting its ability to transport materials upwards. Therefore, in large-volume, flow-through crushing operations, conventional crushers and their conveyor systems easily lead to material accumulation nearby, failing to meet production requirements. In contrast, the adjustable conveyor system described in this embodiment can transport incoming material from the crusher end to distant locations and increase its height as needed. It is adjustable both vertically and horizontally, meeting the requirements for continuous flow material processing and achieving energy conservation and emission reduction.

[0026] Furthermore, the first conveyor belt is provided with an auxiliary support rod, one end of which is hinged to the bottom of the first conveyor belt and the other end is a free end. The turntable of the conveying device is provided with several locking positions, and the free end of the auxiliary support rod can be attached to any of the locking positions on the turntable.

[0027] Furthermore, the outer end of the first conveyor belt can be raised to an angle ranging from 0 to 45 degrees via the vertical adjustment device. That is, starting from a horizontal position, the first conveyor belt swings upwards via the vertical adjustment device, with a maximum swing angle not exceeding 45 degrees. Within this range, the material on the first conveyor belt will not slip off. However, beyond this range, the material will slip off and cannot be conveyed. The length of the first conveyor belt is 5-20 meters. Furthermore, according to actual production conditions, a vertical inclination angle of 40-42 degrees is sufficient to prevent the material on the first conveyor belt from slipping off. However, beyond this range, the probability of the material slipping off increases significantly.

[0028] The horizontal adjustment device has a left-right swing amplitude of less than 120 degrees. The left-right swing amplitude refers to the first conveyor belt swinging to its left limit and to its right limit, and the angle between these two points does not exceed 120 degrees, so as to prevent the crusher from tilting due to excessive lateral force on the first conveyor belt and the material on it.

[0029] Furthermore, the vertical adjustment device is implemented using one or more of the following methods: a pull rod, a cable, a hydraulic cylinder, a rack, a pulley system, or any existing technical solution that achieves the same technical effect.

[0030] Furthermore, the horizontal adjustment device is implemented in a manner including a geared disc, a hydraulic cylinder, a sprocket, or any existing technical solution that achieves the same technical effect.

[0031] Furthermore, the horizontal adjustment device includes a hydraulic cylinder and an adjusting rod. This horizontal adjustment device is located at the bottom of the support base, which has a through hole in the middle. A short shaft is located at the center of the turntable, passing through the through hole and extending downwards. The adjusting rod is rod-shaped and fixed to the short shaft of the turntable. One end of the hydraulic cylinder is hinged to the bottom of the support base, and the other end is hinged to the outer end of the adjusting rod. The horizontal adjustment device is used to adjust the left and right swing of the first conveyor belt. Based on the movable connection between the turntable and the support base, the horizontal adjustment device, i.e., the hydraulic cylinder, needs to provide the driving force to make the first conveyor belt swing along the central axis of the turntable. When the length of the first conveyor belt or the material it carries is too heavy, it will put pressure on the operation of the horizontal adjustment device. Therefore, it is necessary to use an adjustment device such as a hydraulic cylinder with matching power; this is self-evident and will not be elaborated further.

[0032] The second embodiment.

[0033] like Figure 1 As shown, based on the above embodiments, this embodiment provides a material crusher with an adjustable conveying device. The crusher includes a frame, a power system, a transmission system, a crushing system, a feeding device, a discharging device, and a conveying device. The frame provides a support platform and assembly base for the power system, transmission system, crushing system, feeding device, and discharging device. The power system is located at the front end of the frame and provides a power source to the crusher. The transmission system establishes the transmission connection between the power system and the crushing system, feeding device, and discharging device. The feeding device is located on the upper part of the frame and conveys raw materials to the crushing system. The crushing system crushes the raw materials. The discharging device receives the material processed by the crushing system and conveys the material to the conveying device located at the end of the frame. The conveying device receives the material from the discharging device and lifts and conveys the material to a distant end.

[0034] The discharge device includes a second conveyor belt located at the bottom of the crushing system. The second conveyor belt is horizontal or inclined (lower at the front and higher at the back), with its rear end intersecting and staggered with the front end of the first conveyor belt. This staggered arrangement means that material on the second conveyor belt falls in a parabolic trajectory at its end. The first conveyor belt needs to fully catch this material; therefore, the front end of the first conveyor belt is aligned with the end of the second conveyor belt, with the former located below the latter. A more preferable arrangement is to further stagger them, meaning the front end of the first conveyor belt extends beyond the vertical projection of the end of the second conveyor belt. However, this should not be excessive; otherwise, when the first conveyor belt swings horizontally, the parabolic landing point of the material on the second conveyor belt might fall outside the first conveyor belt, causing material spillage. Preferably, the parabolic landing point of the material on the second conveyor belt coincides with the hinge point where the first conveyor belt and the turntable support lug meet, thus preventing material spillage regardless of how the first conveyor belt swings horizontally.

[0035] The third embodiment.

[0036] like Figure 2 , 3As shown, based on the above embodiments, the conveying device in this embodiment is equipped with a counterweight device. This counterweight device is located at the bottom of the support base and includes a counterweight block and a connecting column. The counterweight block and the connecting column are fixedly connected or integrally formed. The connecting column is rectangular, with one end connected to the counterweight block and the other end being a free end. A sleeve is provided at the bottom end of the short shaft of the turntable. The top end of the sleeve is fixedly connected to the short shaft or integrally formed. A square hole with a cross-sectional shape matching the connecting column is provided in the middle of the sleeve. Generally, the self-weight of the conveying device is less than the weight of the crusher. When the first conveyor belt is vertically adjusted or horizontally oscillating within a certain threshold, the weight of the crusher can suppress the shift in weight caused by the adjustment of the conveying device. However, the conveying device may be required to transport materials to higher, farther distances, or larger radius stockpile areas, which may result in the weight of the crusher being unable to suppress the shift in weight caused by the adjustment of the conveying device. Therefore, a counterweight device is required for the conveying device.

[0037] The sleeve is provided with a locking pin, which is used to limit and lock the movement of the connecting post relative to the sleeve.

[0038] The counterweight is equipped with 3-5 casters, which are omnidirectional wheels capable of changing the direction of travel.

[0039] Fourth embodiment.

[0040] like Figure 4 , 5 As shown, based on the above embodiments, the conveying device in this embodiment is equipped with a pressing device. This pressing device is used to prevent material from slipping off the conveyor belt when the first conveyor belt swings vertically to a large angle. The pressing device is a conveyor belt structure parallel to the first conveyor belt. It is assembled and connected to the first conveyor belt through a secondary support (including a support structure, transmission components, etc.). The rotation direction of the pressing device is opposite to that of the first conveyor belt, that is, the top surface of the first conveyor belt and the bottom surface of the pressing device move upward in the same direction. The two support surfaces form a clamping form to press or restrict the material to always remain on the surface of the first conveyor belt and prevent it from slipping off.

[0041] The pressing device includes a third conveyor belt, on which several movable baffles are evenly arranged. Each movable baffle includes a rigid baffle and a stop block. The stop block is fixed on the third conveyor belt. One side of the rigid baffle is hinged to the third conveyor belt near the stop block, and the other side is provided with a flexible plate. The length of the movable baffle is greater than the distance between the top surface of the first conveyor belt and the bottom surface of the third conveyor belt.

[0042] The flexible plate includes a connecting edge and a free edge. The side of the flexible plate that is fixedly connected to the rigid baffle is the connecting edge, and the opposite side is the free edge. The flexibility of the material of the flexible plate gradually changes from hard to soft from the connecting edge to the free edge, that is, the toughness decreases.

[0043] In operation, as the inclination angle of the first conveyor belt increases, the material on it is more likely to slide downwards. At this point, the movable baffle on the third conveyor belt can confine the material between the top surface of the first conveyor belt and the bottom surface of the third conveyor belt. Depending on the inclination angle of the first conveyor belt, the pressure exerted by the material on the movable baffle of the third conveyor belt varies. When the inclination angle is small, the movable baffle experiences less force and is in an inclined state (e.g., Figure 5 (As shown by the mark m), the flexible plate at the front end of the rigid baffle does not deform or deforms very little; when the inclination angle increases, the flexible plate deforms to a certain threshold, and the angle between the movable baffle and the third conveyor belt increases, but the rigid baffle and the flexible plate themselves can withstand the material pressure, and the rigid baffle does not contact the stop block (e.g. Figure 5 (The state indicated by the mark n); When the inclination angle of the first conveyor belt further increases, the pressure of the material on the movable baffle increases to the point that it cannot be supported by the top surface of the first conveyor belt and the bottom surface of the third conveyor belt alone. The rigid baffle is almost vertical, and its back abuts against the stop block (as shown in the image). Figure 5 (As shown in the state marked p), the rigid baffle is prevented from malfunctioning due to excessive oscillation by the stop block. When the movable baffle rotates to the top surface of the third conveyor belt, the rigid baffle and flexible plate oscillate to a state parallel to the third conveyor belt, as shown in the figure. Figure 5 The state indicated by the mark q allows the flexible plate to return to its original shape and maintain its elasticity.

[0044] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
