[0001] The utility model relates to the technical field of anti-smashing buffering, in particular to an anti-smashing buffering device for a conveyor head trough. Background technology:

[0002] In the process of coal processing and transportation, belt conveyors are one of the indispensable equipment, especially in raw coal workshops. Belt conveyors are responsible for transporting coal from one place to another and are a key link in the production process. However, due to the physical properties of coal, such as weight, density, hardness, etc., coal will cause greater impact and wear on belt conveyors and related equipment during transportation, especially the trough part of the belt conveyor head, which is more susceptible to direct impact from large pieces of coal or gangue.

[0003] The traditional solution is usually to improve the impact resistance of the trough by strengthening its material and thickness. However, although this method can reduce equipment damage to a certain extent, it is costly and has limited effect. At the same time, due to the continuous increase in coal transportation volume and fluctuations in coal quality, traditional trough anti-smash measures can no longer meet the needs of actual production. Utility model content:

[0008] Preferably, the locking assembly includes a positioning sleeve and an L-shaped plate, the L-shaped plate is inserted into the positioning sleeve and fixedly connected to the tension spring, the tension spring is fixed in the positioning sleeve, and the positioning sleeve is fixed on the top surface of the positioning plate.

[0009] Preferably, the positioning frame further includes four limiting members, and each limiting member is fixedly connected to the bottom of the positioning plate, and the limiting members can limit the multiple chains.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the anti-smashing buffer device for the trough at the head of the conveyor includes a conveyor 1, a trough 2 is fixed on the conveyor head by a bracket, and buffer plates 3 are fixedly installed on the four sides of the trough 2 by a positioning frame. The buffer plate 3 is formed by splicing a plurality of chains 6 in sequence, and a plurality of locking components 4 are fixed on the top of the positioning frame. The locking components 4 can lock the positioning frame and connect it with the trough 2.

[0020] Specifically, the buffer plate 3 is used to provide the material trough 2 with anti-smashing and buffering functions when the material falls, thereby protecting the material trough from damage and reducing the impact and scattering of the material during the conveying process;

[0021] The buffer plate 3 is installed on the four sides of the trough and fixed by a positioning frame. The buffer plate 3 is formed by splicing a plurality of chains 6 in sequence, which makes the buffer plate 3 have a certain elasticity and toughness, and can provide effective buffering when the material falls. The selection and number of chains 6 depend on the nature of the material, the falling speed and the required buffering effect;

[0022] The locking assembly 4 is installed on the top of the positioning frame and is used to lock the connection between the positioning frame and the material trough 2, so as to ensure that the buffer plate 3 will not be displaced or fall off due to the impact of the material during operation.

[0023] The positioning frame includes four annular fixed positioning plates, the positioning plates are elastic clamps 5 with downward openings, locking bolts are screwed on the elastic clamps 5 at equal intervals, and multiple chains 6 are inserted side by side in the elastic clamps 5;

[0024] Specifically, the elastic clamp 5 has certain elasticity and deformation ability, and multiple chains 6 are inserted side by side in the elastic clamp 5 to form an integral structure. By utilizing the locking bolt, the elastic clamp 5 produces an elastic compression effect to assist in positioning the chain 6.

[0025] The locking assembly 4 includes a positioning sleeve 7 and an L-shaped plate 8. The L-shaped plate 8 is inserted into the positioning sleeve 7 and fixedly connected to the tension spring. The tension spring is fixed in the positioning sleeve 7. The positioning sleeve 7 is fixed on the top surface of the positioning plate.

[0026] The positioning frame also includes four limiting members, and each limiting member is fixedly connected to the bottom of the positioning plate. The limiting members can limit the multiple chains 6 to prevent the bottom of the multiple chains 6 from shaking, thereby ensuring the stability of the multiple chains 6.

[0027] The limiting member includes a U-shaped plate 9, which is sleeved on a plurality of chains 6 and fixed to the bottom of the positioning plate by ropes. Magnet blocks 10 are fixed to both side ends of the U-shaped plate 9, and the magnet blocks can absorb the side walls of the trough 2.

[0028] Specifically, the U-shaped plate 9 is tightly connected with the chain by means of sleeve connection, so as to limit the movement range or position of the chain. The rope is used to fix the U-shaped plate 9 to the bottom of the positioning plate, so that the U-shaped plate 9 can be kept in a fixed position and will not move at will, while ensuring that the U-shaped plate 9 can play its limiting role when needed.

[0029] Magnet blocks 10 are fixed on both side ends of the U-shaped plate 9. The main function of the magnet blocks 10 is to absorb the side walls of the material trough. When the U-shaped plate 9 is fixed to the bottom of the positioning plate, the magnet blocks 10 will be close to the side walls of the material trough and absorbed on them due to magnetic force. In this way, the chain 6 is fixed in a specific position and will not shake at will.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
