Slotting device overcoming incapability of changing slit depth and poor dust removal effect

Abstract

The invention relates to the technical field of concrete, and discloses a slotting device for solving the problems that the slotting depth cannot be changed and the dust removal effect is poor, through cooperative use of a transfer box, a push rod, a first connecting rod, a rotating disc, a spray pipe and a rotating roller, water is automatically sprayed when concrete ground slotting is conducted,sprayed water mist is compact, and can be in full contact with dust, flying dust is prevented from being inhaled into the lung to cause infection during slotting, and dust pollution is reduced; the cutting depth canb e changed through cooperative use of a first threaded rod, a second connecting rod and a second threaded rod, the water spraying amount can be automatically increased when the cutting depth changes, poor dust removal effect due to the fact that the water amount is not changed when dust rises and becomes large when the cutting depth becomes large is avoided, the length of a fenderis synchronously changed after the cutting depth is changed through cooperative use of the cover shell, the positioning rib blocks and the fender, and therefore the fender is prevented from influencing cutting.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a slit device which solves the problem that the slit depth cannot be changed and the dust removal effect is not good. Background technique [0002] Due to the physical characteristics of thermal expansion and contraction of cement concrete, the cement concrete pavement will inevitably produce irregular cracks. In order to prevent the generation of cement concrete pavement, the cement concrete pavement must be slit during construction. However, the existing slit device The setting is relatively simple. On the one hand, there is a baffle on the machine body to block the splashing mud. Since the length of the baffle cannot be stretched, it is inconvenient to adjust the cutting depth, which makes it more inconvenient to perform the cutting operation. On the one hand, in the process of construction, in order to reduce the dust flying during cutting, it is usually necessary to carry o...

Problems solved by technology

[0002] Due to the physical characteristics of thermal expansion and contraction of cement concrete, the cement concrete pavement will inevitably produce irregular cracks. In order to prevent the generation of cement concrete pavement, the cement concrete pavement must be slit during construction. However, the existing slit device The setting is relatively simple. On the one hand, there is a baffle on the machine body to block the splashing mud. Since the length of the baffle cannot be stretched, it is inconvenient to adjust the cutting depth, which makes it more inconvenient to perform the cutting operation. On the one hand, in the process of construction, in order to reduce the dust flying during cutting, it is usually necessary to carry out watering operations with a water pipe. Due to the limited length of the water pipe, it is often inconvenient to use, and the amount of water sprayed cannot match the cutting Synchronize the depth changes of different devices, which is time-consuming and labor-intensive to use

[0003] Aiming at the deficiencies of the prior art, the present invention provides a slit device that can not change the slit depth and has poor dust removal effect. It solves the problem that the existing slitting device is relatively simple to set up, and ensures that the cutting depth can be adjusted when the device is used for operation, and the baffle can automatically expand and contract without affecting the cutting. At the same time, when the cutting depth becomes deeper, it can Automatically adjust the water spray volume, save time and effort, and improve the intelligence of the device when it is used
