Problems solved by technology

When using a stone chip spreading system with a conveyor belt type silo and a hydraulic telescopic screw spreader, if the belt feeds too much material, the thickness of the screw spreader will be small, resulting in material leakage; at the same time , when the control of the electrical travel switch is not in place, the adjustment position is inappropriate, or when the automatic spreading operation is stopped and the material is forgotten to be turned off, the leakage of stone materials will also occur, resulting in waste of materials and increased costs. At the same time, it affects the quality of construction

Embodiment 1

[0028] see Figure 1-7 As shown, the gravel spreading device is built on the road surface, including:

[0029] Spreading box 20, the box bottom surface of spreading box 20 has a material spreading groove 21,

[0030] Rotating assembly 60, rotating assembly 60 is installed on the wall surface of two grooves of material spreading tank 21, and rotating assembly 60 is used for realizing the opening or closing of material spreading port 21, and

[0031] Hinge 40, hinge 40 comprises the first vane 42 that one end is connected with spreading box 20 box walls, and the other end of first vane 42 is connected with connecting shaft 41, is also connected with rotatable second vane 43 on the connecting shaft 41,

[0032] Wherein, an air bag 50 is provided between the second blade 43 and the wall of the spreading box 20 . The spreading tank 21 is a rectangular tank body. Two corresponding box walls of the spreading box 20 are connected with symmetrically arranged hinges 40 .

[0033]The...

Embodiment 2

[0042] see Figure 1-7 As shown, the pavement trimmed gravel spreading device includes the spreading box 20 as a rectangular box shape, and the upper end surface of the spreading box 20 is opened, and the air bag 50 is connected with the air pump through the air pipe, which is not shown in the figure, but should be the Those skilled in the art understand that the filling / deflation technology of the airbag 50 will not be described too much here, the airbag 50 is placed between the second blade 43 and the box wall of the spreading box 20, the screen 30 is a metal mesh plate, and its net The size of the hole is selected according to the requirements of actual gravel spreading. The number of partitions 61 on the support shaft body 62 is preferably 4. The partitions 61 surround the support shaft body 61 with an interval angle of 90°. The gravel box 10 is a rectangular box. body, the upper end is opened, so that gravel falls into the gravel box 10, and the briquetting block 74 is a ...

Embodiment 3

[0045] When the gravel spreading device for road construction of the present invention is actually used: the device of the present invention is installed on a movable device, such as a car or a trolley, and there is no shelter under the bottom of the specific spreading box 20, so as to meet the requirements of spreading. Gravel requirement, the box walls on both sides of the spreading box 20 are connected and fixed with the movable equipment. During the gravel spreading process, the motor 23 is started to control the rotation of the rotating assembly 60 to realize the opening and closing of the spreading trough 21, and then the spreading The gravel in the box 20 is scattered downward, and the gravel entering the spreading box 20 needs to be filtered by the screen 30. If the gravel screened by the screen 30 is too large, the gravel will slide down to the gravel box along the screen 30. 10, the crushed stone component 70 crushes the crushed stones with too large particle size and...

Abstract

The invention discloses a crushed stone spreading device for pavement construction, and belongs to the technical field of road paving. The crushed stone spreading device comprises a spreading box, rotating assemblies and hinges; a scattering groove is formed in the box bottom face of the spreading box; the rotating assemblies are mounted on the two groove wall faces of the scattering groove and used for opening or closing a scattering opening; the hinges comprise first blades with one ends being connected with the box walls of the spreading box, the other ends of the first blades are connectedwith connecting shafts, and rotatable second blades are further connected to the connecting shafts, wherein airbags are arranged between the second blades and the box walls of the spreading box; thescattering groove is a rectangular groove body; and the symmetrically-arranged hinges are connected to the two corresponding box wall faces of the spreading box. According to the crushed stone spreading device, crushed stone is spread without leakage, the spreading amount is controllable, the volume of a spreading container is controllable, the clearance degree of the spread stone is small, and the construction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of road paving, and in particular relates to a gravel spreading device for road construction. Background technique [0002] Synchronous gravel sealing vehicle is a commonly used construction machinery, which is mostly used in laying bridges, roads and other fields. At present, there are roughly three types of stone chip spreading systems for synchronous gravel sealing vehicles: conveyor belt type silo plus hydraulic telescopic screw spreader, inclined self-weight falling hopper plus point spreader and hopper lifting type silo plus point pattern Spreaders, among them, the hopper lifting type silo plus split type spreader is widely used due to its high quality of stone chip spreading. When using a stone chip spreading system with a conveyor belt type silo and a hydraulic telescopic screw spreader, if the belt feeds too much material, the thickness of the screw spreader will be small, resulting in material lea...
