Embodiment 1

[0027] A back box for cobblestone paving, such as Figure 1-3 As shown, it includes a belt-type back box 1, a plug cover 2, a discharge pipe 3 and an extension tube 4. The top of the belt-type back box 1 is connected with a detachable plug cover 2, and the discharge end at the bottom of the belt-type back box 1 is connected to There is a feeding pipe 3, and an extension pipe 4 is connected to the end of the feeding pipe 3. The belt-type back box 1 communicates with the extension pipe 4 through the feeding pipe 3. It also includes an adjustment assembly 5 and a quantitative assembly 6. The extension pipe 4 is equipped with Regulating component 5 and quantitative component 6.

[0028] The adjustment assembly 5 includes an internally threaded pipe 51, an externally threaded pipe 52 and a lower barrel 53. The end of the extension pipe 4 is connected with an internally threaded pipe 51, and the internally threaded pipe 51 is threadedly connected with an externally threaded pipe 52....

Embodiment 2

[0032] On the basis of Example 1, such as Figure 4-7 As shown, also includes a binder assembly 7, the binder assembly 7 includes a rotating shaft 71, a driving lever 72, a swing lever 73, a pressing lever 74, a pressing plate 75, a clamping lever 76, a connecting rod 77, an elastic member 78 and a torsion spring 79 , the left side of the internally threaded pipe 51 is rotationally connected with a rotating shaft 71, and the rotating shaft 71 is connected with four driving rods 72 evenly spaced in the circumferential direction. The outer right side of the pipe 51 is rotationally connected with a fork 73, and a torsion spring 79 is connected between the fork 73 and the internally threaded pipe 51. The fork 73 cooperates with the driving lever 72, and the inside of the fork 73 is slidably connected with a pressure bar 74. There is a certain resistance between the pressure rod 74 and the swing rod 73. Two clamp rods 76 are connected to the right front side of the lower barrel 53....

Abstract

The invention relates to a back box, in particular to a back box for cobblestone laying and aims to solve the technical problem of how to design a back box for cobblestone laying, which does not needworkers to bend down or squat for laying cobblestone during operation and enables the workers to work more easily to improve working efficiency. The back box for cobblestone laying comprises a belt type back box, an adjusting assembly and a quantifying assembly; the top of the belt type back box is connected with a detachable plug cover; the discharging end of the bottom of the belt type back boxis connected with a discharging pipe; the tail end of the discharging pipe is connected with an extension pipe; the belt type back box is communicated with the extending pipe through the discharging pipe; the adjusting assembly is arranged on the extension pipe; and the quantifying assembly is arranged on the extension pipe. According to the back box, cobblestones are laid at the positions needinglaying through cooperation of the adjusting assembly and the quantifying assembly, and therefore a cobblestone laying effect is achieved.

Description

technical field [0001] The invention relates to a back box, in particular to a back box for cobblestone laying. Background technique [0002] Pebbles are named for their resemblance to cobblestones. As a pure natural stone, pebbles are taken from the sand and gravel mountains formed by the uplift of the ancient riverbed after the crustal movement thousands of years ago. When building some parks and other buildings, it is usually necessary to lay some pebbles to make the scene more beautiful. [0003] At present, the way of laying cobblestones is usually to manually bend down or squat down to press the cobblestones one by one on the position where the cobblestones need to be laid. The above method needs to be laid manually by bending down or squatting down during operation, which is very easy to fatigue when laying. affect work efficiency. [0004] Therefore, there is no need to artificially bend over or squat down to lay when needing to develop a kind of operation, make t...
