A rubble device for ground pit extension

Abstract

The application provides a gravel equipment for foundation pit expansion, and belongs to the technical field of gravel equipment. The gravel equipment for foundation pit expansion comprises a protection assembly and a dust suction assembly. The stone blocks can be crushed through a crushing box. The dust generated by the crushed stones in the crushing box can be absorbed through an air suction pump, a dust suction hood, a filter box and a spraying piece. The dust in the filter box can be humidified through the spraying piece, thereby further improving the dust removal effect. When the stone blocks are crushed by the crushing box, the baffle moves through the driving frame on both sides of the crushing box. The baffle moves downward until the crushed stones splashed during the crushing of the stone blocks are blocked. On the one hand, the splashing of the crushed stones is prevented, and on the other hand, the dust is better prevented in cooperation with the dust suction, thereby facilitating the absorption of the dust generated by the crushed stones, preventing the influence on the surrounding environment, and preventing the stone blocks from splashing everywhere during the crushing of the crushed stones, thereby improving the practicability.

Description

Technical Field

[0001] This application relates to the field of stone crushing equipment, and more specifically, to a stone crushing equipment for expanding a deep foundation pit. Background Technology

[0002] In building construction, the expansion of the foundation pit is a key step to ensure the stability and bearing capacity of the foundation. Stone is an indispensable material. When facing different building construction objects, the standard for the size of the stones will also change. Therefore, it is often necessary to crush the stones so that they can meet the required size for construction. For example, a stone crushing device with Chinese patent application number CN202322165199.0 includes a main body of the device and a high-efficiency pressurization device. This invention enables a faster and more efficient stone crushing process through a high-efficiency pressurization device. A pressurization pump converts low-pressure fluid into high-pressure fluid to suit specific industrial or production applications. The pressurization pump is typically driven by a transmission device, employing a more efficient motor or rotary power transmission. A throttle valve controls the output flow and pressure of the pressurization pump. A conveyor belt system transports the raw material from the feed inlet to the crushing and grinding devices for processing. The crushing rollers compress the raw material into flakes, reducing its volume and preparing it for the next process. The crushing rollers are key components in the stone crusher, with varying numbers and shapes of teeth to accommodate materials of different particle sizes and hardness.

[0003] However, the above solution still has certain drawbacks: First, the dust generated by crushing the stone is not easy to absorb, and the dust raised can easily affect the surrounding environment. Second, the main body of the device is in a semi-enclosed state, and stones will fly everywhere during the crushing process, which can easily cause people to be injured, thus reducing its practicality. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a stone crushing device for expanding deep foundation pits, which aims to improve the problems of dust generation during stone crushing in related technologies, which is inconvenient to absorb and the dust raised can easily affect the surrounding environment. In addition, the main body of the device is in a semi-enclosed state, and stones will fly everywhere during the crushing process, which can easily cause injury to people, thus reducing the practicality of the device.

[0008] In the above process, when the conveyor sends the stone to pass through the first crushing roller, the first motor can drive the first crushing roller and the second crushing roller to rotate, which can crush the stone. The second motor can drive the first rolling roller and the second rolling roller to rotate, which can crush the stone and further improve the crushing effect.

[0009] In one specific implementation, the drive frame includes a bracket, a third motor, and a screw. The third motor is disposed on one side of the bracket, the screw is rotatably connected to the bracket, and the screw is fixedly connected to the output end of the third motor.

[0010] In the above process, the third motor can drive the screw to rotate, and the rotation of the screw can drive the baffle to rise and fall.

[0011] In one specific implementation, a screw block is provided on one side of the baffle, the screw block is threadedly connected to the screw rod, the screw block is slidably connected to the bracket, and a slider is provided on one side of the baffle, the slider is slidably connected to the bracket.

[0012] In the above implementation process, a screw block is provided on one side of the baffle, which can serve as a connection.

[0013] In one specific implementation, a connecting pipe is provided on one side of the air pump, and the connecting pipe is connected to the filter box.

[0014] In the above implementation process, a connecting pipe is installed on one side of the air pump, which can serve as a connection.

[0015] In one specific implementation, the filter box includes a box body, a filter plate, and a collection box, wherein the filter plate is slidably connected to the box body, and the collection box is slidably connected to the box body.

[0016] In the above process, dust can be filtered through the filter plate and collected and processed through the collection box.

The pump body is connected to the water tank, the atomizing nozzle is disposed inside the tank, the water pipe is disposed on one side of the pump body, the water pipe passes through and connects to one side of the tank, and the water pipe is connected to the atomizing nozzle.

[0018] In the above process, water from the water tank is pumped to the atomizing nozzle, which wets the dust and further improves the dust removal effect.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: Stones are conveyed into the crushing chamber via a conveyor, where they are crushed. A vacuum pump, dust hood, filter box, and spray system absorb dust generated during crushing. The spray system also wets the dust inside the filter box, further improving dust removal efficiency. When the crushing chamber crushes the stones, drive frames on both sides move baffles downwards to block flying fragments. This prevents fragments from flying and, in conjunction with the vacuum system, better prevents dust accumulation, facilitating the absorption of dust generated during crushing and preventing environmental impact. It also prevents stones from flying everywhere during crushing, thus improving practicality. Attached Figure Description
