Description

Technical Field

[0001] The utility model relates to the technical field of raw material transportation, and more specifically to a raw material elevator. Background Art

[0002] A material elevator is a mechanical device used to lift and transport bulk materials in a vertical or nearly vertical direction. It plays a vital role in industrial production, especially in situations where a large amount of materials need to be stored, mixed, processed and transported. The most commonly used material elevator is a bucket elevator. In a chain bucket elevator, the motor drives the sprocket to rotate, and then the sprocket drives the chain to rotate. The chain drives the bucket fixed to the surface to flip, thereby realizing the transportation and unloading of materials.

[0003] In the prior art, the bucket and chain of the bucket elevator are mainly connected by welding or bolted connection. Welding is a permanent connection method, which means that once the bucket and the chain are connected together by welding, if the bucket is damaged or needs to be replaced, it is very difficult to separate the bucket and the chain. Complex processes such as cutting are required, which consumes a lot of time and labor costs. It may also cause a certain degree of damage to the chain, affecting the subsequent use of the chain. In addition, the welding quality is affected by many factors, such as the technical level of the welder, the performance of the welding equipment, the welding environment, etc. If the welding process has quality problems such as loose welding, pores, slag inclusions, etc., the connection between the bucket and the chain is prone to breakage during the long-term operation of the bucket elevator, affecting the normal operation of the equipment. The bolt connection requires drilling holes at corresponding positions on the bucket and the chain. During installation, the bolts need to be passed through these holes and the nuts need to be tightened. The operation is relatively cumbersome, and it is difficult to install and remove the bolts in a small space, which increases the maintenance time and cost of the equipment. Utility Model Content

[0006] The cam is secured to the chassis and has a locking plate, which is adapted to lock the chassis and to provide a locking plate for locking the chassis.

[0007] Furthermore, the top and bottom of the slot are both provided with a slot, the top and bottom of the fixed plate are both fixedly connected to a limiting column, the outer surface of the limiting column is slidably connected to the inside of the slot, and the outer surface of the fixed plate is slidably connected to the inside of the slot.

[0008] Furthermore, the surface of the clamping block is arc-shaped, the surface of the clamping block is meshed and connected to the inside of the tooth groove, and the end surface of the clamping block extends to the outer surface of the fixing plate.

[0009] Furthermore, the inclined groove is a parallelogram, and steel balls are equidistantly and movably installed inside the positioning plate. The surfaces of the steel balls extend to the outer surface of the positioning plate and are rollingly connected to the inner wall of the inclined groove.

[0010] Furthermore, the outer surfaces of the connecting rod and the pressure plate are both slidably connected to the inside of the fixing plate, and the outer surface of the sealing plate is sealingly slidably connected to the inside of the sealing groove.

[0011] Furthermore, the interiors of the air outlet pipe and the air inlet pipe are both connected to the interior of the sealing groove, and the interior of the sealing groove is connected to the outside of the fixed plate through the air outlet pipe and the direct-flow one-way valve. The diameter of the air inlet pipe is smaller than the diameter of the air outlet pipe, and the outer surface of the sliding plate is slidably connected to the interior of the limit groove.

[0024] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0025] Figure 1-Figure 8 It is the best embodiment of the utility model, and the following Figure 1-Figure 8The utility model is further described.

[0026] Specifically, the raw material elevator comprises a bucket elevator body 1 and a chain 2 which is rotated inside the bucket elevator body 1 by electric drive, a bucket 3 is equidistantly connected to the inside of the bucket elevator body 1, slots 31 are provided on both sides of the bucket 3, tooth grooves 33 are equidistantly provided inside the slot 31, and a positioning assembly 4 is installed between the chain 2 and the bucket 3;

[0027] The positioning assembly 4 includes a fixed plate 41 fixedly connected to the surface of the chain 2, a limiting groove 42 is provided inside the fixed plate 41, a limiting rod 43 is fixedly connected inside the limiting groove 42, a sliding plate 44 is slidably connected to the outer surface of the limiting rod 43, a block 45 is fixedly connected to the surface of the sliding plate 44 at equal intervals, a connecting column 46 is fixedly connected at the center of the surface of the sliding plate 44, an oblique groove 47 is provided on the surface of the connecting column 46, a positioning plate 48 is slidably connected inside the oblique groove 47, a connecting rod 49 is fixedly connected to the surface of the positioning plate 48, a pressing plate 410 is fixedly connected to the end surface of the connecting rod 49, a sliding rod 411 is fixedly connected to the surface of the pressing plate 410, a sealing plate 412 is fixedly connected to the end surface of the sliding rod 411, a sealing groove 413 is provided inside the fixed plate 41, a spring 414 is movably installed inside the sealing groove 413, an air outlet pipe 415 and an air inlet pipe 417 are fixedly connected inside the fixed plate 41, and an air inlet pipe 417 is fixedly installed on the end surface of the air outlet pipe 415.

[0028] In this embodiment, by setting the positioning component 4, when the surface of the block 45 is engaged with the tooth groove 33, the hopper 3 can be positioned by the fixing plate 41, so that the hopper 3 and the chain 2 can be quickly aligned and fixed, which greatly improves the installation efficiency and saves time and labor costs. When the equipment needs maintenance or replacement of the hopper 3, the positioning component 4 can be quickly disassembled and reinstalled, which simplifies the maintenance operation and reduces the difficulty and cost of maintenance.

[0029] Specifically, a card slot 32 is opened at the top and bottom of the slot 31, and a limiting column 321 is fixedly connected to the top and bottom of the fixing plate 41. The outer surface of the limiting column 321 is slidably connected to the inside of the card slot 32, and the outer surface of the fixing plate 41 is slidably connected to the inside of the slot 31.

[0030] In this embodiment, by providing the card slot 32 and the limit column 321, the sliding of the fixed plate 41 inside the slot 31 can be accurately positioned, and at the same time, the friction between the hopper 3 and the fixed plate 41 can be increased, thereby enhancing the firmness between the hopper 3 and the fixed plate 41 and enhancing practicality.

[0031] Specifically, the surface of the clamping block 45 is arc-shaped, the surface of the clamping block 45 is meshed and connected to the inside of the tooth groove 33 , and the end surface of the clamping block 45 extends to the outer surface of the fixing plate 41 .

[0032] In this embodiment, due to the shape of the clamping block 45 , when installing the fixing plate 41 and fixing the hopper 3 , the pressure plate 410 is not required, and the clamping block 45 can slide inside the slot 31 and can be directly engaged with the inside of the tooth groove 33 .

[0033] Specifically, the inclined groove 47 is a parallelogram, and steel balls are equidistantly and movably installed inside the positioning plate 48 . The surfaces of the steel balls extend to the outer surface of the positioning plate 48 and are rollingly connected to the inner wall of the inclined groove 47 .

[0034] In this embodiment, by providing steel balls, the friction between the positioning plate 48 and the inner wall of the inclined groove 47 can be reduced, thereby extending the service life of the positioning plate 48.

[0035] Specifically, the outer surfaces of the connecting rod 49 and the pressing plate 410 are both slidably connected to the inside of the fixing plate 41 , and the outer surface of the sealing plate 412 is sealingly slidably connected to the inside of the sealing groove 413 .

[0036] In this embodiment, by applying pressure to the pressure plate 410 , the sealing plate 412 can be driven to slide, and the air inside the sealing groove 413 can be squeezed out.

[0037] Specifically, the interiors of the air outlet pipe 415 and the air inlet pipe 417 are both connected to the interior of the sealing groove 413, and the interior of the sealing groove 413 is connected to the exterior of the fixed plate 41 through the air outlet pipe 415 and the direct-flow one-way valve 416. The diameter of the air inlet pipe 417 is smaller than the diameter of the air outlet pipe 415, and the outer surface of the sliding plate 44 is slidably connected to the interior of the limit groove 42.

[0038] In this embodiment, by providing an air inlet pipe 417, after the pressure plate 410 stops applying external force, the pressure plate 410 will not be immediately reset by the elasticity of the spring 414, but the external air slowly enters the sealing groove 413 through the air inlet pipe 417, and then passes through the spring 414, causing the spring 414 to slowly reset. Therefore, after pressing the pressure plate 410 once, the staff can disengage from the operating pressure plate 410 and directly pull the hopper 3 with both hands to remove it, which greatly improves the installation efficiency and saves time and labor costs.

[0039] The working principle and use process of the utility model are as follows: when the hopper 3 needs to be replaced, pressure is applied to the pressure plate 410, and the pressure plate 410 drives the connecting rod 49 to slide through the sliding rod 411, so that the positioning plate 48 slides deep into the interior of the inclined groove 47, and the friction between the positioning plate 48 and the connecting column 46 drives the sliding plate 44 to slide through the connecting column 46. At this time, the sliding plate 44 drives the block 45 to slide into the interior of the limiting groove 42, and the block 45 gradually disengages from the interior of the tooth groove 33. When the block 45 is completely out of contact with the interior of the tooth groove 33, the hopper 3 can be pulled to disengage the hopper 3 from the fixed plate 41, and the hopper 3 can be removed. While applying pressure to the pressure plate 410, the pressure plate 410 drives the sealing plate 412 to slide through the sliding rod 411. At this time, the air inside the sealing groove 413 is discharged through the air outlet pipe 415 and the direct current one-way valve 416. When the pressure plate 410 stops applying external force, the pressure plate 410 will not be reset immediately through the elasticity of the spring 414, but the external air slowly enters the sealing groove 413 through the air inlet pipe 417, and then passes through the spring 414, causing the spring 414 to slowly reset. Therefore, after pressing the pressure plate 410 once, the staff can disengage from the operating pressure plate 410 and directly pull the hopper 3 with both hands to remove it, which greatly improves the installation efficiency and saves time and labor costs. When the equipment needs maintenance or replacement of the hopper 3, it can be quickly disassembled and reinstalled through the setting of the positioning component 4, which simplifies the maintenance operation and reduces the difficulty and cost of maintenance.
