Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to unloading control in block material conveying scenarios, and particularly to a synchronous lifting variable trough angle plow unloader. Background Technology

[0002] In the material conveying industry, especially in the conveyor belt transport of bulk materials, existing fixed plow-type unloaders have significant drawbacks. When not unloading, the parallel idlers supporting the belt are too flat. When material on the belt reaches this section, the vibration of the idlers causes the material to continuously spill along both sides of the belt. This problem leads to the following adverse consequences:

[0003] 1. The equipment has poor operational stability, frequently malfunctions and stops, which seriously affects production efficiency;

[0004] 2. Staff in this position need to spend a lot of time and energy cleaning up spilled materials, significantly increasing their workload;

[0005] Currently, there is a lack of unloader structures on the market that can effectively solve the above problems. There is an urgent need to develop a new type of unloading device that can automatically adjust the belt groove angle in both unloading and non-unloading states to prevent material spillage. Utility Model Content

[0006] The purpose of this utility model is to provide a variable trough angle synchronous lifting plow unloader, which, through a unique synchronous lifting structure design and in conjunction with a variable trough angle idler group, achieves precise synchronous lifting of the idler group and the plow head, changes the belt trough angle, effectively solves the problem of material spillage in the non-unloading section, reduces labor intensity, improves production efficiency, and improves the working environment.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A synchronous lifting variable trough angle plow-type unloader includes a belt support 1, a belt 3, and a plow head 2. The plow head 2 is located on the belt 3. A U-shaped channel steel support 4 is provided on the belt support 1. An electric hydraulic push rod 5 is hinged to the top crossbeam of the channel steel support 4. The push rod end of the electric hydraulic push rod 5 is hinged to the plow head 2. The plow head support 6 at the front end of the plow head 2 is hinged to the upright of the channel steel support 4 through a large pin 7. A lifting idler frame 8 is provided on the belt support 1 below the belt 3. Parallel idler rollers are installed on the lifting idler frame 8 in the left and right directions. The front end of the lifting idler frame 8 is hinged to the plow head support 6 at the front end of the plow head 2 through a connecting rod.

[0009] The lifting roller frame 8 includes mounting plates arranged in parallel on the left and right sides. The front and rear ends of the two mounting plates are connected together by a connecting plate. The parallel roller group is installed between the two mounting plates. The front and rear ends of the mounting plates are hinged to a lower connecting rod 9 by a pin 14. The lower end of the lower connecting rod 9 is hinged to the belt bracket 1.

[0010] The mounting plate is hinged to an upper connecting rod 10 at its front end, and the plowshare bracket 6 is fixed to a fixed connecting rod 11 at its lower front end. The upper connecting rod 10 and the fixed connecting rod 11 are hinged together by a connecting shaft 12.

[0011] A pair of variable trough angle idler groups 13 are symmetrically arranged on the left and right sides of the belt support 1 on the rear side of the lifting idler frame 8. The variable trough angle idler group 13 includes a variable trough angle idler frame and idlers arranged on the variable trough angle idler frame.

[0012] The variable trough angle idler frame includes a vertical frame and a mounting frame. The lower end of the vertical frame is fixed on the belt support 1, and the upper end of the vertical frame is hinged to the middle of the front and rear side plates of the mounting frame. The idler is installed in the mounting frame by rotating in the left and right direction.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. Highly efficient reduction of material spillage: Through the variable trough angle idler group and the strict synchronous lifting mechanism of the plow head, the belt can accurately restore the trough shape in the non-discharging state. Compared with traditional unloaders, it can more effectively prevent material from spilling due to idler vibration in the non-discharging section, and significantly improve the stability and reliability of material conveying.

[0015] 2. Significantly reduced labor intensity: The reduction in the amount of spilled materials significantly reduces the workload of staff cleaning up spilled materials, thus significantly reducing labor intensity.

[0027] Example 1

[0028] like Figure 1As shown, this embodiment provides a synchronous lifting variable groove angle plow-type unloader, including a belt support 1, a belt 3, and a plow head 2. The plow head 2 is located on the belt 3. A "U"-shaped channel steel support 4 is provided on the belt support 1. An electric hydraulic push rod 5 is hinged to the top crossbeam of the channel steel support 4. The push rod end of the electric hydraulic push rod 5 is hinged to the plow head 2. The plow head support 6 at the front end of the plow head 2 is hinged to the upright of the channel steel support 4 through a large pin 7. A lifting idler frame 8 is provided on the belt support 1 below the belt 3. A parallel idler group is installed on the lifting idler frame 8 in the left and right direction. The lifting idler frame 8 is specifically a rectangular frame structure. The parallel idler group is rotatably installed in the rectangular frame structure in the left and right direction. The front end of the lifting idler frame 8 is hinged to the plow head support 6 at the front end of the plow head 2 through a connecting rod.

[0029] The lifting roller frame 8 includes mounting plates arranged in parallel on the left and right sides. The front and rear ends of the two mounting plates are connected together by connecting plates (the two mounting plates and the two connecting plates are welded to form a rectangular frame structure). The parallel roller group is installed between the two mounting plates. The front and rear ends of the mounting plates are hinged to the lower connecting rod 9 by the pin 14. The lower end of the lower connecting rod 9 is hinged to the belt bracket 1.

[0030] The mounting plate is hinged to an upper connecting rod 10 at its front end, and the plowshare bracket 6 is fixed to a fixed connecting rod 11 at its lower front end. The upper connecting rod 10 and the fixed connecting rod 11 are hinged together by a connecting shaft 12.

[0031] A pair of variable trough angle idler groups 13 are symmetrically arranged on the left and right sides of the belt support 1 at the rear of the lifting idler frame 8. The variable trough angle idler group 13 includes a variable trough angle idler frame and idlers arranged on the variable trough angle idler frame. One section of the idler is located under the belt 3, and the other section extends out of the belt 3.

[0032] The variable trough angle idler frame includes a vertical frame and a mounting frame. The lower end of the vertical frame is fixed on the belt support 1, and the upper end of the vertical frame is flexibly hinged to the middle of the front and rear side plates of the mounting frame. The idler is installed in the mounting frame by rotating in the left and right direction.

[0033] When the plow head rotates upward and the lifting idler frame 8 and the parallel idler group installed on it descend, the middle part of the belt loses support and descends under the gravity of the material on it, until it reaches the parallel idler group. At this time, the mounting groove hinged to the upright and the idler in the mounting groove tilt at 45° under the action of unbalanced force.

[0034] This invention, based on the lever principle, constructs an innovative connecting and actuating structure (upper connecting rod 10, fixed connecting rod 11, and lower connecting rod 9) to cleverly connect the plowshare bracket and the lifting roller frame. The lifting roller frame is connected to the channel steel bracket on which the electro-hydraulic push rod is installed via the connecting rod. This connection method ensures that the electro-hydraulic push rod can stably and reliably drive the lifting roller frame and the parallel roller group on it to move, thereby driving the variable trough angle roller group to achieve state change. Through this connecting structure, the parallel roller group and the plowshare can achieve precise synchronous lifting and lowering; that is, when one rises or falls, the other moves synchronously with the same motion trend and reasonable motion amplitude under the linkage of the connecting rod.

[0035] The variable trough angle idler group in this invention, driven by the lifting and lowering of the plowshare, raises and lowers the parallel idler group. The belt changes its running trajectory according to the operating state of the variable trough angle idler group, achieving flexible switching between a parallel and troughed state. The variable trough angle idler group, through a flexible connection structure between the variable trough angle idler frame and the shaft pin, allows the idlers to freely adjust their angle according to the belt's operating state, thus achieving variability in the trough angle during belt operation. The advantage of the variable trough angle idler group lies in its adaptability to the conveying needs of different materials: for example, when conveying large or heavy materials, the trough angle can be increased to enhance material cohesion and reduce spillage; while when conveying light or bulk materials, the trough angle can be appropriately decreased to reduce belt running resistance. This design improves the adaptability and conveying efficiency of the belt conveyor under different operating conditions.

[0036] The working process of this utility model is as follows: 1. Non-unloading state: The hydraulic push rod is activated, and the power output of the hydraulic push rod drives the plow head and plow head support to rise (e.g. Figure 1 The part in red is Figure 4 (As shown). Under the synergistic effect of the lever principle and connecting rod, the parallel idler group descends accordingly. At this time, the variable trough angle idler group changes angle from a parallel state (forming a 45° angle state) back to a trough shape as the belt runs. As the shape of the idler group changes, the working surface of the belt also returns to a trough shape. This trough structure can effectively constrain the material, allowing it to pass smoothly on the trough belt, greatly avoiding the situation where the material spills in the non-discharge section due to the vibration of the idler.

[0037] 2. Unloading state: Operating the hydraulic push rod causes the plow blade to lower the frame; simultaneously, the parallel idler rollers rise under the action of the connecting rod (e.g., Figure 1 The black lines in the middle and Figure 3 (As shown). The variable trough angle idler group returns to a parallel state as the conveyor belt changes. At this time, the plow head of the plow-type unloader is in close contact with the parallel belt, thus achieving efficient unloading. Throughout the process, the state transitions of the plow head and the variable trough angle idler group are strictly synchronized, ensuring the accuracy and reliability of the unloading operation.
