Description

Technical field:

[0001] The utility model relates to the field of transportation, in particular to a straight barrel chute which is anti-smashing and can be self-closed. Background technology:

[0002] During the production process, the coal feeder belt tail end drops coal, and falls to the next belt through the straight chute. During this period, the falling coal impacts the inner wall of the chute, forming a chute drop point, and the falling coal falls out from the bottom of the chute. In actual use, the following problems occur:

[0003] 1. The chute drop point is constantly subjected to the impact of materials. The welded lining plate at the chute drop point is very easy to wear, and a lot of manpower and material resources are consumed in the inspection and maintenance of the lining plate.

[0004] 2. When the straight chute lets the material fall, the bottom is open to facilitate the material to fall and be directly transported. However, in this structure, in winter, cold wind blows directly from the bottom of the straight chute and rises to the coal feeder belt, causing the coal feeder outlet gate to freeze. When the temperature is low, the coal feeder gate cannot be opened and the material cannot be discharged, affecting normal production. Utility model content:

[0005] The utility model aims to provide a straight tube chute which is anti-smashing and can be closed automatically.

[0006] The utility model is implemented by the following technical solutions:

[0007] A smash-proof and self-closing straight chute, comprising a straight chute and a tail end of a coal feeder belt inserted in the straight chute, and also comprising a groove structure, a stopper door, and a counterweight block, wherein a groove structure is fixed at a drop point on the inner wall of the straight chute;

[0008] Two baffles are symmetrically arranged at the bottom of the straight chute, and the baffles are in an inverted V shape. The arched parts on the top of the two baffles are respectively hinged to the two sides of the bottom of the straight chute. The baffle is placed on one end of the outer side of the straight chute to fix the counterweight block, and a groove structure is fixed on the top of the baffle at the bottom of the straight chute.

[0009] Preferably, the groove structure comprises a pair of triangular plates, and a notch between the pair of triangular plates forms the groove.

[0010] Advantages of the utility model:

[0011] 1. A small part of the falling materials rush into the groove of the groove structure for temporary storage. When most of the other materials hit the groove, it is the materials that are impacted, not the liner or the inner wall of the straight chute. The materials are used to bear the impact of the materials, which reduces the wear of the liner or the inner wall of the straight chute and reduces the manpower and material resources consumed in inspection and maintenance.

[0012] 2. There are two rotating shutter doors at the bottom of the straight chute. When no material is falling, they are automatically closed by counterweights, preventing cold air from rising from the bottom and reducing the possibility of the outlet gate of the coal feeder being frozen. When the material falls, it can also strike the shutter doors by its own weight to open the bottom of the straight chute and fall normally. The shutter doors also have a groove structure, which can similarly reduce the wear of the shutter doors. Brief Description of the Drawings:

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0014] Figure 1 is a schematic diagram of the overall structure of the present invention;

[0015] Figure 2 is a schematic diagram of the working state of the present invention.

[0016] In the figure: straight chute 1, tail end of the coal feeder belt 2, groove structure 3, shutter door 4, counterweight 5, triangular plate 6, groove 7. Detailed Embodiment:

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Such as Figure 1 、 Figure 2As shown, a smash-proof and self-closing straight chute comprises a straight chute 1 and a tail end 2 of a coal feeder belt inserted in the straight chute 1, and also comprises a groove structure 3, a baffle 4, and a counterweight 5. When materials fall from the tail end 2 of the coal feeder belt, they will impact the inner wall of the opposite straight chute 1, and the impact point will form a drop point. A groove structure 3 is fixed at the drop point on the inner wall of the straight chute 1, and the groove structure 3 comprises a pair of triangular plates 6. The notch between the pair of triangular plates 6 forms a groove 7, and the area formed by the groove 7 is larger than the contact area of ​​the original drop point. The falling materials are coal blocks or particles, and a small part of them rushes into the groove 7 of the groove structure 3 for temporary storage. When most of the other materials impact the groove 7 again, it is the materials that are impacted, rather than the liner or the inner wall of the straight chute 1. The materials are used to bear the impact of the materials, thereby reducing the wear of the liner or the inner wall of the straight chute 1, and reducing the manpower and material resources consumed in inspection and maintenance. After the materials have fallen, a small part of the materials in the groove 7 can also fall out.

[0019] Two baffles 4 are symmetrically arranged at the bottom of the straight chute 1. The baffles 4 are in an inverted V shape. The arched parts at the tops of the two baffles 4 are hinged to the two sides of the bottom of the straight chute 1 respectively. The baffles 4 are placed at one end of the outer side of the straight chute 1 to fix a counterweight 5. A groove structure 3 is fixed on the top of the baffles 4 at the bottom of the straight chute 1. One end of the two baffles 4 is subjected to the gravity of the counterweight 5 and rotates downward, while the other end is placed upward at the bottom of the straight chute 1, so that the bottom of the straight chute 1 is closed. In winter, when no materials are moving, the cold wind can not rise from the bottom, reducing the possibility of the coal feeder outlet gate being frozen. Secondly, when materials fall, the baffles 4 are hit by their own weight, and the baffles 4 are turned over to open the bottom of the straight chute 1, so that the materials fall normally. When the amount of materials is small, the bottom of the straight chute 1 can be half-open (the baffles 4 are half open and half closed). When the amount of materials is large, the straight chute 1 can be fully opened (the baffles 4 are fully opened).

[0020] When the material falls onto the baffle 4 , it also contacts the groove structure 3 first. Similarly, the material is temporarily stored in the groove 7 of the groove structure 3 , and the material is used to withstand the impact of the material, thereby reducing the wear of the baffle 4 .

[0021] Working principle: When the utility model is in use, the material falls from the tail end 2 of the coal feeder belt and impacts the groove structure 3 on the inner wall of the straight chute 1. A small part of the material rushes into the groove 7 of the groove structure 3 for temporary storage. When most of the other materials impact the groove 7, it is the material that is impacted, reducing the wear of the liner or the inner wall of the straight chute 1; the material continues to fall, relying on its own weight to hit the groove structure 3 on the baffle door 4, the baffle door 4 flips over, opens the bottom of the straight chute 1, and allows the material to fall normally.

[0022] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
