DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.

[0030] Embodiment one

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ​The utility model provides a technical scheme: a manual tamper for earthwork backfilling rear corner, including tamper board 1, tamper board 1 is the steel sheet of thickness 15mm, the top fixed assembly of tamper board 1 is equipped with connecting mechanism 6, and the tamper board 1 can be driven to carry out up and down action through handheld connecting mechanism 6, thereby tampering the soil of earthwork backfilling rear corner and carries out the tampering treatment.

[0032] The assembly part 2 is integrally formed at the four corners of the tamper board 1, and the assembly part 2 is an inclined chamfer with a certain angle. The bottom of the tamper board 1 is equipped with an assembly plate 3. The top of the assembly plate 3 is integrally formed with an assembly block 4 corresponding to the position of the assembly part 2. The assembly block 4 and the assembly part 2 are detachably connected and fixed by a fixing screw. The assembly plate 3 is a steel plate with a thickness of 7mm, as shown in the figure, the bottom of the assembly plate 3 is integrally formed with auxiliary crushing blocks 5 evenly distributed in a circle. The edge of the auxiliary crushing block 5 is provided with a relatively sharp inclined chamfer. Figure 4

[0033] Working principle: if there are many stones in the area during the process of tampering the soil, and the process of crushing stones by the tamper board 1 is relatively laborious, the assembly plate 3 can be assembled at the bottom of the tamper board 1. During the up and down movement of the tamper board 1, the auxiliary crushing block 5 can crush the stones, thereby enhancing the crushing efficiency of the stones.

[0034] Embodiment two

[0035] Compared with embodiment one, the difference of the present embodiment is that:

[0036] Specifically, referring to Figure 1 , Figure 5 and Figure 6 , the connecting mechanism 6 is a T-shaped single rod connecting mechanism.

[0037] The connecting mechanism 6 includes a first base 61, which is welded and fixed at the center of the tamper board 1. The top of the first base 61 is fixedly assembled with one end of a first PVC pipe 62. The other end of the first PVC pipe 62 is fixedly assembled with a first connecting seat 63, which is in an inverted T shape. The left and right ends of the first connecting seat 63 are respectively fixedly connected with second PVC pipes 64.

[0038] ​The first PVC pipe 62 is detachably and fixedly connected with the first base 61 and the first connecting seat 63 through fixing screws, and the second PVC pipe 64 is also detachably and fixedly connected with the first connecting seat 63 through fixing screws. The first PVC pipe 62 is a PVC pipe with a pipe diameter of 90 mm, and the second PVC pipe 64 is a PVC pipe with a diameter of 50 mm. The PVC pipes are used to replace the traditional solid wooden handle and ramming plate 1, which not only reduces the overall weight of the rammer, making the operator more labor-saving during soil ramming, but also reduces the transmission of vibration to the handle during ramming compared with the solid wooden handle, making the operator more comfortable during soil ramming.

[0039] As shown in Figure 5 The first reinforcing frame 65 is welded and fixed between the side wall of the first base 61 and the ramming plate 1, which can increase the stability of the connection between the first base 61 and the ramming plate 1.

[0040] As shown in Figure 6 The outer side walls of the bottom end and the top end of the first PVC pipe 62 are respectively sleeved with the first rubber sleeve 66, and the first rubber sleeve 66 is located in the first base 61 and the first connecting seat 63, respectively. Since the first PVC pipe 62 is vertically arranged, the first rubber sleeve 66 arranged at the connection between the first PVC pipe 62 and the first base 61 and the first connecting seat 63 can increase the friction between them, thereby strengthening the connection stability of the first PVC pipe 62 with the first base 61 and the first connecting seat 63, avoiding loosening of the connection between the first PVC pipe 62 and the first base 61 and the first connecting seat 63 during repeated ramming of the soil with the rammer, and causing safety hazards.

[0041] As shown in Figure 6 The outer side end of the second PVC pipe 64 is inserted with the first rubber plug 67, which seals the end of the second PVC pipe 64 to protect the operator from being scratched on the hand during holding the second PVC pipe 64. The outer side wall of the second PVC pipe 64 is sleeved with the first anti-skid sleeve 7, which can enhance the stability of the operator during gripping the second PVC pipe 64.

[0042] Working principle: as Figure 5As shown in the utility model, when the corner of the earthwork backfill is tamped, the first base 61, the first PVC pipe 62, the first connecting seat 63 and the second PVC pipe 64 are sequentially assembled and fixed, in the process of tamping, the operator holds the first anti-skid sleeve 7 of the outer wall of the second PVC pipe 64 with both hands, drives the tamping plate 1 to reciprocate in the up-down direction through the second PVC pipe 64, and tamps the soil at the corner through the tamping plate 1.

[0043] Example three

[0044] Compared with example one, the difference of the utility model lies in that:

[0045] Specifically, referring to Figure 2 , Figure 7 and Figure 8 , the connecting mechanism 6 is a parallel double-bar type connecting mechanism.

[0046] The connecting mechanism 6 comprises a second base 68, the top of the second base 68 is welded and fixed with a second connecting seat 69, and the top of the second connecting seat 69 is fixed and assembled with a third PVC pipe 610 in left-right symmetry.

[0047] The second base 68 is composed of a fixed part and a connecting part, the fixed part is a steel pipe with a hollow inside, which reduces the overall weight of the second base 68, and the fixed part is welded and fixed with the tamping plate 1, the connecting part is a circular steel plate, and the connecting part is used for connecting and fixing with the second connecting seat 69, a second reinforcing frame 611 is welded and fixed between the second base 68 and the tamping plate 1 in a circumferential uniform distribution, the stability of the connection and fixation between the second base 68 and the tamping plate 1 is increased by arranging the second reinforcing frame 611, the second connecting seat 69 is in Y shape, the bottom of the second connecting seat 69 is welded and fixed on the surface of the connecting part of the second base 68, the top of the second connecting seat 69 is integrally formed with a connecting groove 612 in left-right symmetry, the connecting groove 612 is used for the insertion of the third PVC pipe 610, and the installation position of the third PVC pipe 610 is fixed by the fixing screw screwed on the side wall of the second connecting seat 69 after the third PVC pipe 610 is inserted into the connecting groove 612, and the third PVC pipe 610 is a PVC pipe with a diameter of 50 mm.

[0048] As shown in the utility model, Figure 8 The bottom of the third PVC pipe 610 is sleeved with a second rubber sleeve 613, and the second rubber sleeve 613 is located in the connecting groove 612, the stability of the connection and fixation between the third PVC pipe 610 and the second connecting seat 69 is increased by arranging the second rubber sleeve 613, and the connection between the third PVC pipe 610 and the second connecting seat 69 is prevented from loosening in the process of moving up and down.

[0049] The top of the third PVC pipe 610 is equipped with a second rubber plug 614. The second rubber plug 614 is arranged to close the top of the third PVC pipe 610. Since the top of the third PVC pipe 610 is the cutting position of the pipe, the second rubber plug 614 can prevent the top of the third PVC pipe 610 from scratching the operator during use of the tool.

[0050] The outer wall of the third PVC pipe 610 is fixedly attached with a positioning block 8 by glue. The positioning block 8 is annular. Each outer wall of the third PVC pipe 610 is provided with two positioning blocks 8. A second anti-skid sleeve 9 is arranged between the two positioning blocks 8. The second anti-skid sleeve 9 is sleeved on the outer wall of the third PVC pipe 610. The second anti-skid sleeve 9 can enhance the stability when the third PVC pipe 610 is gripped.

[0051] Working principle: Compared with the technical solution in example two, the third PVC pipe 610 vertically arranged in left-right symmetry is adopted instead of the second PVC pipe 64 arranged horizontally. Since the height of the operator is different, the height position of the second PVC pipe 64 is fixed in example two. The operators with different heights may be affected by the gripping height when they grip the second PVC pipe 64 to operate the ramming plate 1, and the comfort degree is reduced. The outer wall of the third PVC pipe 610 is provided with a vertical gripping area. The operator can select the appropriate gripping position of the third PVC pipe 610 according to his own height, so as to enhance the comfort degree in the operation process.
