[0002] The belt conveyor is a commonly used material conveying equipment, which has the advantages of high conveying efficiency, strong conveying capacity, stable operation, etc., and is mainly used for conveying various solid bulk materials, such as ores, coal, etc. In the prior art, the belt conveyor conveys the bulk materials to the top of the storage bin or the next-stage belt conveyor, and the plough installed above the belt discharges the materials into the discharge hopper beside the belt, and then falls onto the storage bin below the discharge hopper or the belt of the next-stage belt conveyor.

[0003] At present, the plough often adopts the form of direct contact between the plough blade and the belt. This method is easy to wear the plough blade. Especially when the conveyed material is sand with high water content, the wear of the plough blade is more serious. The material will increase the leakage rate along with the wear of the plough blade, which has a great impact on the discharging efficiency and stability of the plough, and results in a greatly shortened service life of the plough blade, requiring frequent replacement, large maintenance workload, and affecting the production efficiency.

[0007] Both the mounting plate and the baffle are made of metal materials, and the metal materials can be steel.

[0008] The scraper is made of high molecular polyethylene material.

[0029] In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0030] Refer to Figure 1 and Figure 2 As shown, the present utility model discloses a blocking type ploughing mechanism, which includes a plough 20 installed above the belt 10 of a belt conveyor, and a mounting plate 1, a scraper 2, and a baffle 3 that extend in the same direction;

[0031] The mounting plate 1 is arranged above the belt 10, is parallel to the plough 20, and the end of the mounting plate 1 is connected to the discharge hopper 30 of the belt conveyor;

[0032] The scraping plate 2 is connected to the lower edge of the mounting plate 1, and the scraping plate 2 has a clearance fit with the belt 10, which is used to block most of the materials so as to prevent the materials from flowing through the mounting plate 1 to the rear ploughing device 20.

[0033] The upper edge of the enclosing plate 3 is connected to the side of the mounting plate 1 facing the material, and a spacing d is reserved between its lower edge and the upper surface of the belt 10, so that a cavity 50 with an opening 40 is formed among the mounting plate 1, the scraping plate 2, the enclosing plate 3 and the belt 10, and the material can enter and accumulate in the cavity 50.

[0034] The following shows the specific embodiments of the present invention.

[0035] Both the above-mentioned mounting plate 1 and the enclosing plate 3 are made of high-hardness and wear-resistant materials, such as metals like steel, etc., to ensure the overall strength and service life of the ploughing mechanism.

[0036] The above-mentioned scraping plate 2 is made of high molecular polyethylene material, which has the characteristics of low density, light weight, wear resistance, impact resistance and corrosion resistance. It can greatly improve the service life of the front-end barrier ploughing mechanism, and thus cooperate with the rear ploughing device 20 to achieve that the ploughing device 20 does not need to be replaced for a long time.

[0037] The above-mentioned mounting plate 1 can be installed on the side of the existing belt conveyor's ploughing device 20 facing the material (i.e., the front side) through the bracket 4, and the material is unloaded in front of the front end of the ploughing device 20 to reduce the impact of the material on the ploughing device 20.

[0038] Furthermore, the above-mentioned ploughing device 20 is installed above the belt 10 through the fixing frame 60, and the bracket 4 is fixedly connected above the side of the ploughing device 20 facing the material, so that the mounting plate 1 and the ploughing device 20 are relatively fixed on the same fixing frame 60 and can be disassembled and replaced synchronously.

[0039] Secondly, a welding process is adopted between the mounting plate 1 and the ploughing device 20 to form an integral body.

[0040] At the same time, the above-mentioned bracket 4 includes several pairs of vertical rods 41 perpendicular to the mounting plate 1 and the ploughing device 20, and inclined rods 42 inclined relative to the mounting plate 1 and the ploughing device 20; both ends of the vertical rods 41 and the inclined rods 42 are respectively fixedly connected to the mounting plate 1 and the ploughing device 20. By connecting between the mounting plate 1 and the ploughing device 20 through rods in different directions, the strength can be improved.

[0041] The above-mentioned enclosing plate 3 includes an inclined plate 31 and a vertical plate 32 formed by bending the same plate; the upper edge of the inclined plate 31 is fixedly connected to the surface of the mounting plate 1, and a spacing d is reserved between the lower edge of the vertical plate 32 and the upper surface of the belt 10. The enclosing plate 3 in this form can make the volume of the cavity 50 larger so as to accommodate enough materials to achieve the barrier type of discharging of "material hitting material".

[0042] A baffle can be selectively installed at the front end of the above-mentioned cavity 50 to prevent materials from leaking out from the front end of the ploughing mechanism (i.e., the side of the belt 10 away from the feeding hopper 30). In fact, since 60% - 80% of the materials are concentrated in the middle position of the cavity 50 (i.e., near the midline of the belt 10) during transportation, the probability of overflow at the front end is very low.

[0043] Through the above solution, the utility model can be used in combination with the existing plough 20 of the belt conveyor and is arranged at the front end of the plough 20 to contact the materials first. Since the mounting plate 1, the scraper 2, the enclosing plate 3 and the belt 10 enclose a cavity 50 with an opening 40 for materials to enter and accumulate, during the transportation of the materials, some materials will enter and accumulate in the cavity 50 to form a "material wall". Thus, the principle of "material hitting material" can be utilized to reduce the impact force of the materials on the ploughing mechanism through the mutual collision between the materials and block the advancement of the materials to achieve discharging into the feeding hopper 30. The materials no longer directly impact the scraper 2 of the ploughing mechanism and the blade of the rear plough 20, and will become denser as more materials enter the cavity 50, and the effect of blocking the materials becomes more obvious. The wear rate of the scraper 2 and the blade is greatly reduced, the service life is prolonged, and the leakage rate is greatly reduced. Moreover, the utility model can reduce the working load of the plough 20 and the rear sweeper, improving the cleaning efficiency of the entire conveying system.

[0044] The above embodiments and diagrams do not limit the product form and style of the utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the utility model.
