Description

Technical Field

[0001] This utility model relates to belt conveyors, and more specifically to a belt conveyor protection device. Background Technology

[0002] Chinese patent application number 202323246634.9 discloses a belt conveyor head protection device, including a frame, a head roller, a middle roller, and a tail roller rotatably connected to the frame in sequence. The head roller is rotatably connected to the middle roller and the tail roller via a belt. An anti-deviation unit is provided on the frame between the head roller and the tail roller, and a coal pile protection unit is provided on the other side of the tail roller. The anti-deviation unit is connected to the belt drive. A high-temperature protection unit is connected to the frame near the middle roller via a crossbar. It has the characteristics of high-temperature protection, coal pile protection, and anti-deviation protection during belt conveyor head transportation.

[0003] However, in actual use, materials tend to accumulate at the end of the belt conveyor, which is the feeding section, and the materials can easily damage the belt conveyor when they fall from a certain height. The Chinese patent with application number 202323246634.9 does not provide protection for the end of the belt conveyor.

[0004] A search revealed Chinese patent application number 202410122039.4, which discloses a material guide chute for a mining conveyor and its usage method. The chute includes a frame and a mounting cover fixedly mounted on the top of the frame via a support frame. A conveyor belt is internally connected to the frame, and a feed frame is fixedly mounted inside the mounting cover. A material guide mechanism is located inside the feed frame. The material guide mechanism includes guide plates rotatably mounted on both sides of the inner wall of the feed frame. This invention relates to the field of mining conveyor technology. This material guide chute and its usage method, through the material guide mechanism, allows for adjustment of the material feed rate and speed according to actual needs. Furthermore, the two guide plates buffer the material during its descent, reducing the impact of the vertical drop on the conveyor belt and extending its service life. Simultaneously, it guides and corrects the material, concentrating it in the middle of the conveyor belt and preventing material dispersion that could affect transmission efficiency.

[0005] However, Chinese Patent Application No. 202410122039.4, paragraph 0030, describes the following: "When personnel pour material into the feed frame 4 from the top surface, they start the motor 59, causing the motor 59 to drive the lead screw 510 to rotate. Then, the sliding block 511 on the lead screw 510 slides up and down along it. When the sliding block 511 slides downwards along the lead screw 510, the rotation of the push rod 512 at both ends allows the opposite sides of the two guide plates 51 to rotate along the inner wall of the feed frame 4. The opposite sides of the two guide plates 51 simultaneously tilt downwards, separating them, thus increasing the distance between the two guide plates 51." (Refer to the accompanying drawings in the specification.) Figure 2 During the process of material falling, it will impact the guide plate, which will cause the sliding block and lead screw to be stressed. Over time, this will damage the motor, sliding block and lead screw.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a belt conveyor protection device that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A protective device for a belt conveyor includes: a frame, a belt, and a power source for moving the belt; a feed hopper is installed on the frame; and a material distribution mechanism is installed on the feed hopper.

[0010] The material distribution mechanism includes: a feeding hopper, a cylinder for driving the feeding hopper to move, a fixed rod fixedly installed on the feeding hopper, a spring sleeved on the fixed rod, a sliding sleeve that slides in contact with the fixed rod, the spring abutting against the sliding sleeve, and a feeding hopper fixedly connected to the sliding sleeve.

[0011] Furthermore, a contact element is installed on the feed hopper, and the contact element slides on the feed hopper.

[0012] Furthermore: the cylinder is connected to the hopper via a connector, the connector having an elongated hole, and the hopper being fixedly connected to a connecting rod, which is inserted into the elongated hole and slides in contact with the connector.

[0013] Furthermore: support rollers are installed on the frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the belt conveyor protection device of the present invention uses springs to buffer and dampen shocks. When the material acts on the feeding hopper, the springs can reduce the force and avoid impacting the cylinder, making the piston rod of the cylinder less prone to damage.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 5 As shown, the present invention relates to a protective device for a conveyor belt, comprising: a frame 1, a conveyor belt 2, and a power source 3 for moving the conveyor belt 2. The power source 3 is a motor, and a rotating roller, which is a power roller, is connected to the motor shaft. The power roller is installed at one end of the frame 1, and a driven roller is installed at the other end of the frame 1. The conveyor belt 2 contacts the power roller and the driven roller. When the motor drives the power roller to rotate, the conveyor belt 2 moves accordingly. Support rollers are installed on the frame 1. The support rollers are divided into a flat support roller 4 and an inclined support roller 5. The flat support roller 4 is installed directly below the conveyor belt 2 and is used to support the material. The inclined support rollers 5 are installed on both sides of the conveyor belt 2. Due to the setting of the inclined support rollers 5, the conveyor belt 2 is higher on both sides and lower in the middle, thereby facilitating the transportation of materials.

[0025] The frame 1 is equipped with a feeding hopper 6; the feeding hopper 6 is equipped with a material distribution mechanism; the material distribution mechanism is used to distribute the material throughout the feeding hopper 6, to prevent the material from accumulating in one position of the feeding hopper 6, and to prevent excessive pressure on a certain part of the tape 2, thereby playing a protective role.

[0026] The material distribution mechanism includes: a feeding hopper 7, a cylinder 9 for driving the feeding hopper 7 to move, a fixed rod 73 fixedly installed on the feeding hopper 7, a spring sleeved on the fixed rod 73, and a sliding sleeve 81 that slides in contact with the fixed rod 73. The spring abuts against the sliding sleeve 81, and a feeding hopper 8 is fixedly connected to the sliding sleeve. In actual use, the spring acts as a buffer and shock absorber. When material acts on the feeding hopper 8, the spring can reduce the force and prevent impact on the cylinder 9, thus preventing damage to the piston rod of the cylinder 9.

[0027] It should be noted that the feeding hopper 8 is funnel-shaped. When the material impacts the upper end of the feeding hopper 8, the belt 2 can be protected by the buffering and shock absorption effect of the spring. The cylinder 9 drives the feeding hopper 8 to move through the fixed rod 73 and the sliding sleeve 81. The spring can reduce the axial vibration of the sliding sleeve 81.

[0028] As a further improvement of this utility model, a contact member 71 is installed on the hopper 7. The contact member 71 slides on the feed hopper 6 and is in sliding contact with the feed hopper 6. That is to say, the friction between the contact member 71 and the feed hopper 6 is small. A roller can be installed on the contact member 71 to change the sliding to rolling to further reduce the friction. It should be noted that the roller has two functions: first, it supports the hopper 7 to prevent the piston rod of the cylinder 9 from being subjected to radial force and protects the cylinder 9; second, it makes the hopper 7 move better and the movement is smoother.

[0029] As a further improvement of this utility model, the cylinder 9 is connected to the hopper 7 via a connector 10. The connector 10 is provided with an elongated hole 101. The hopper 7 is fixedly connected with a connecting rod 72. The connecting rod 72 is inserted into the elongated hole 101 and slides in contact with the connector 10. Even if a portion of the force is applied to the hopper 7, the piston rod of the cylinder 9 can be prevented from being subjected to radial force under the action of the contact member 71. Moreover, the elongated hole 101 can further prevent damage to the piston rod of the cylinder 9. In other words, when the hopper 7 is subjected to force, it will not move up and down under the support of the rollers, thus preventing damage to the piston rod of the cylinder 9. Even if there is slight up and down movement, the connecting rod 72 slides in the elongated hole 101, preventing the connector 10 from being subjected to force, thus preventing damage to the piston rod of the cylinder 9. At the same time, the connector 10 can drive the hopper 7 to move through the connecting rod 72.

[0030] Working principle:

[0031] When the material acts on the feeding hopper 8, the spring can reduce the force and avoid impacting the cylinder 9, making the piston rod of the cylinder 9 less prone to damage.
