AI Technical Summary
The existing dust collection hoods lack buffer devices, making the protective nets easily damaged when impacted by large rock particles, thus affecting dust removal operations.
The dust collection hood is equipped with a combination structure of a fixing ring, a guide rod, a buffer spring, and a protective net. The guide rod passes through the protective net, and the buffer spring connects the fixing ring and the protective net to buffer the impact force.
It effectively reduces damage to protective nets and dust collection hoods caused by large rock particles, extends their service life, and ensures the normal operation of dust removal work.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and more specifically to a dust collection hood. Background Technology
[0002] Dust is one of the major hazards plaguing coal mine production. High concentrations of dust, especially respirable dust, are a direct cause of pneumoconiosis in workers. Rock dust, a type of respirable dust, is particularly severe, making the reduction of dust concentration, especially rock dust, essential and a major technical challenge. To solve this problem, dust collection devices must be installed on tunneling machines. Existing dust collection devices generally include dust hoods, ventilation ducts, and dust collector fans. Currently, to prevent large rock particles from entering the dust collection device through the dust hood and causing blockages, protective nets are usually installed inside the dust hood. These nets ensure dust collection while intercepting large rock particles. However, existing dust hoods lack buffering devices. When the protective net is impacted by large rock particles, it cannot be cushioned, easily damaging the net and the dust hood, thus affecting dust collection operations. Utility Model Content
[0003] In view of this, the present invention provides a dust collection cover, the purpose of which is to solve the problems existing in the prior art.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A dust collection hood includes: a dust collection hood body; a fixing ring inside the dust collection hood body; a plurality of guide rods at the bottom of the fixing ring; a protective net below the fixing ring; the guide rods passing through the protective net; the protective net and the guide rods being slidably disposed relative to each other; a buffer spring sleeved on the outside of the guide rods; one end of the buffer spring being fixedly connected to the bottom of the fixing ring, and the other end of the buffer spring being fixedly connected to the top of the protective net.
[0006] Preferably, there are four guide rods; the four guide rods are evenly distributed at the bottom of the fixing ring.
[0007] Preferably, the buffer spring is fitted with a rubber protective sleeve on its outer side.
[0008] Preferably, the inner wall of the dust collection hood is provided with a limiting groove; correspondingly, the outer wall of the protective net is provided with a limiting slider that is adapted to the limiting groove; the limiting slider is slidably connected in the limiting groove.
[0009] Preferably, the number of limiting slide grooves is four; the four limiting slide grooves are evenly distributed on the inner wall of the dust collection hood body; the number of limiting sliders is the same as the number of limiting slide grooves, and they are set in a one-to-one correspondence.
[0010] Preferably, a limiting ring is provided at the bottom of the dust collection hood body.
[0011] Compared with the prior art, the present invention has achieved the following technical effects: The present invention uses components such as a fixing ring, a guide rod, a buffer spring, and a protective net to work together. When the protective net is hit by large rock particles, the buffer spring can buffer the impact force generated by the collision, thereby greatly reducing the damage caused by large rock particles to the protective net and the dust collection hood, and extending the service life of the dust collection hood.
