Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel conveying technology, specifically a sand and gravel conveying anti-scattering device. Background Technology

[0002] As a core raw material in construction, infrastructure, and road engineering, sand and gravel directly affect project efficiency, cost control, and operational safety in their transportation. In recent years, my country's infrastructure investment has continued to grow, exhibiting the characteristics of "long-distance, high-load, and continuous" transportation. For example, large sand and gravel aggregate plants need to transport raw materials from mining areas to crushing workshops (transportation distances can reach hundreds of meters), concrete mixing plants need to accurately transport sand and gravel of different particle sizes to batching bins (daily transportation volume can reach thousands of tons), and construction sites need to transport sand and gravel from raw material piles to mixers (mostly temporary and mobile transportation scenarios). Sand and gravel are prone to scattering due to impact and bouncing. Existing devices mostly rely on passive blocking (baffles) rather than active flow control, which cannot solve the problem of sand and gravel scattering at its root.

[0003] Meanwhile, the dust control conveying device for sand and gravel in a mixing plant, with application number CN201920218000.7, includes belt conveyors connected by transfer buckets. Each transfer bucket includes a feed hopper and a discharge hopper, which are connected by an inclined conveying pipe. The feed hopper is also equipped with a dust cover, and the discharge hopper has a discharge gate on the same side as the lower belt conveyor in the direction of movement. An exhaust hood is installed along the upper side of the conveying pipe, and the exhaust hood is connected to a negative pressure exhaust pipe. The lower end of the discharge hopper is no more than 1 cm away from the upper surface of the lower belt conveyor. The exhaust hood is arc-shaped, and the cross-section of the conveying pipe is rectangular, with a cross-sectional area 2-3 times the cross-sectional area of ​​the sand and gravel flow.

[0004] However, the following problems were found in the implementation of the relevant technology: it can only block or prevent sand and gravel from overflowing along the surface of the conveyor belt. However, most of the sand and gravel are falling freely from the hopper at high impact speed, causing the material to bounce and scatter above the baffle after hitting the conveyor belt. The impact of the sand and gravel will cause the baffle to deform and wear. At the same time, it does not control the material flow pattern, which makes the material flow to one side of the conveyor belt during unloading, or the material flow to concentrate in the middle to form a material mound, which can easily lead to excessively thick material layers at the edges overflowing.

[0005] Therefore, we propose a device to prevent sand and gravel from scattering during transport. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an anti-scattering device for sand and gravel conveying, which has the advantages of reducing the impact force and speed of materials falling onto the conveyor belt, preventing sand and gravel from bouncing and scattering when they hit the conveyor belt, and guiding the material out of the conveyor belt by diverting it through the guide plate to reduce edge scattering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel conveying anti-scattering device, comprising a base plate, a conveyor belt mounted on the base plate, baffles on both sides of the conveyor belt, a support plate fixedly connected to the upper surface of the baffles, a slot on the support plate, positioning holes on the front and rear sides of the slot, a guide plate detachably connected inside the slot, and a positioning post fixedly connected to the outer surface of the guide plate; a material cylinder, a conveying pipe fixedly connected to the lower surface of the material cylinder; and a mounting base, a motor fixedly connected to the outer surface of the mounting base, with an auger fixedly connected to the output end of the motor.

[0008] Preferably, the baffle is fixedly connected to the base plate, and the upper side of the baffle is inclined.

[0009] Preferably, the auger is located inside the conveying pipe, the auger is rotatably connected to the conveying pipe, and a support is fixedly connected to the lower surface of the conveying pipe.

[0010] Preferably, the positioning post is provided with a slot, and the positioning hole is provided with a spring ball.

[0011] Preferably, the slot is movably connected to the spring ball, and the positioning post is movably connected to the positioning hole.

[0012] Preferably, a handle is fixedly connected to the upper surface of the guide plate, and the handle is provided with anti-slip texture.

[0013] Preferably, one end of the conveying pipe is fixedly connected to a feeding plate, and one end of the feeding plate is located above the conveyor belt.

[0014] Preferably, a feeding box is detachably connected to the base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the cooperation of baffles, conveying pipes, mounting bases, motors, and augers, uses augers to uniformly convey materials, thereby reducing the impact force and speed of materials falling onto the conveyor belt, and significantly reducing [material consumption / damage].

[0017] The kinetic energy during the falling process prevents sand and gravel from bouncing and scattering when they hit the conveyor belt, thus reducing the possibility of materials falling off the conveyor belt. At the same time, it can prevent materials from hitting the conveyor belt with high impact force, causing multiple losses to the equipment, protecting the conveying equipment, extending its service life, and reducing maintenance costs.

[0018] 2. This utility model, through the cooperation of support plate, slot, positioning hole, guide plate and positioning column, diverts the material output by the guide plate, which can break down the concentrated columnar material flow into several uniform sheet-like material flows and guide them to be evenly distributed in the width direction of the conveyor belt, so as to promote the uniform falling of the material segments and guide the landing point, reduce impact and bounce, reduce edge scattering, and facilitate disassembly and installation. When the wear is large in the later stage, it is easy to replace the new guide plate to ensure the use effect. Attached Figure Description

[0030] Furthermore, the positioning post 13 is provided with a slot 14, and a spring ball is provided in the positioning hole 11. When the positioning post 13 is inserted into the positioning hole 11, the spring ball protrudes into the hole under the action of the spring, forming a point contact with the post end or the hole wall, providing positioning and locking. The slot 14 can guide or restrict the displacement of the ball, so that it is engaged in the edge of the slot 14 at a specific position, enhancing the positioning reliability and repeatability, and is used to fix the position of the positioning post 13, thereby fixing the position of the guide plate 12.

[0031] It is worth noting that the slot 14 is movably connected to the spring ball, and the positioning post 13 is movably connected to the positioning hole 11.
