Description

Technical Field

[0001] The utility model relates to the technical field of garden greening construction, and more particularly to a rammer for garden greening construction. Background Art

[0002] In the existing technology, in the process of landscaping construction, ground leveling and soil compaction are crucial steps, which directly affect the subsequent growth of vegetation and landscape effects. However, traditional tamping machines often face many challenges in this application scenario. Many existing tamping equipment lacks an efficient transmission mechanism, which makes it impossible to perform continuous and stable tamping operations, seriously affecting work efficiency and quality. The energy conversion efficiency of these equipment is low, which not only causes energy waste, but also accelerates the wear of the equipment and greatly shortens its service life. In addition, due to the lack of a reliable fixing mechanism, the connection between the tamping plate and the casing is often unstable, and it is easy to loosen or fall off during operation, which increases safety hazards. Replacing the tamping plate or adjusting the equipment also becomes difficult and time-consuming, greatly reducing work efficiency. After long-term use, the connection between the various components of the equipment may gradually loosen, further accelerating the wear and aging of the equipment, and ultimately leading to premature scrapping of the equipment.

[0003] In modern landscaping construction, the diversity and complexity of terrain place higher demands on tamping equipment. Different terrain conditions, such as flat land, slopes, narrow spaces, or soils of varying hardness and softness, require the use of tamping plates of different types or sizes to achieve the best compaction effect. However, tamping machines in the existing technology often have a common problem: they are not easy to quickly install the tamping plates. This design flaw makes the initial installation process cumbersome and time-consuming, requiring specialized tools and skills, and greatly reduces the efficiency of the equipment. For example, some models of tamping machines may require the removal of multiple bolts or complex fixings to complete the installation of the tamping plate, which not only increases labor intensity but also prolongs equipment preparation time, affecting the overall construction progress.

[0004] In addition, during the actual construction process, engineers often need to replace tamping plates in a timely manner according to different terrain and soil conditions to ensure the best compaction effect. However, the existing tamping machine design often ignores this actual demand, resulting in the inconvenience of quickly replacing tamping plates according to different terrains in the later stage. This limitation seriously affects the flexibility and efficiency of construction. For example, when the construction team moves from a flat lawn area to the edge of a narrow flower bed, it may be necessary to replace the tamping plate with a smaller size. If the replacement process is complicated and time-consuming, it will not only interrupt the workflow, but may also lead to construction delays and increased costs. Utility Model Content

[0032] A positioning hole 19 is provided at the top of the fixing rod 10, and there are multiple groups of positioning holes 19.

[0034] A compression spring 23 is provided between the top plate 17 and the snap-fit sleeve.

[0035] A limiting mechanism is provided on the outside of the fixed sleeve 11, and the limiting mechanism includes a transmission sleeve 24, a limiting block 25, a limiting hole 26 and a screw 27. The transmission sleeve 24 is slidably installed on the outer wall of the fixed sleeve 11, and a plurality of limiting blocks 25 are provided and installed on the top surface of the transmission sleeve 24. The limiting holes 26 are provided on a plurality of groups of arc rods 13. The screw 27 is provided with a plurality of groups rotatably installed on the fixed sleeve 11 and threadedly connected with the transmission sleeve 24. By rotating the screw 27, the position of the transmission sleeve 24 can be precisely controlled, thereby realizing the precise locking of the arc rod 13 by the limiting block 25. The setting of multiple groups of limiting blocks 25 and limiting holes 26 provides multi-point locking, which greatly enhances the reliability of the fixation. At the same time, this design also facilitates the operator to adjust the locking force according to actual needs, thereby improving the adaptability of the equipment.

[0036] In this embodiment, the operator first moves the rammer to the designated position by means of the handle 18, then connects the ramming plate 8 to the housing 1 through the fixing mechanism, inserts the fixing rod 10 into the connecting block 9 and the housing 1, and then inserts the fixing sleeve 11 into the fixing rod 10. When the fixing rod 10 is inserted into the fixing sleeve 11, the cooperation between the positioning rod 20 and the positioning hole 19 further enhances the connection stability. Then, the top end of the fixing rod 10 pushes the top plate 17, so that the top plate 17 pushes the multiple groups of top blocks 16, thereby The multiple sets of arc rods 13 are pushed to slide along the movable holes 12, so that the clamping blocks 14 at the bottom ends of the multiple sets of arc rods 13 are clamped in the clamping grooves 15 provided on the outer wall of the fixed rod 10, thereby fixing the fixed rod 10. The limit bars 21 slide in the limit grooves 22 to ensure the accuracy of the movement of the arc rods 13. When the control sleeve 28 is rotated, the inner gear ring 29 drives the gear 30 meshing with it to rotate, thereby driving the screw 27 to rotate. When the screw 27 is rotated, the transmission sleeve 24 threadedly connected to the screw 27 will rotate. The outer wall of the fixing sleeve 11 slides up and down, and when the transmission sleeve 24 moves up, the multiple groups of limit blocks 25 installed on the top surface of the transmission sleeve 24 will enter the limit holes 26 on the arc rod 13, forming a secondary lock, and realizing the precise positioning of the limit blocks 25. This double locking mechanism greatly improves the stability and reliability of the connection between the ramming plate 8 and the shell 1. When it is necessary to adjust the position or replace the ramming plate 8, it is only necessary to operate the fixing mechanism and the limit mechanism to quickly complete the replacement, which greatly improves the work efficiency. Then start the motor 2. When the motor 2 is started, the driving wheel 3 installed at the output end of the motor 2 starts to rotate. The driving wheel 3 drives the transmission wheel 5 to rotate through the transmission belt 6, and then the center shaft 4 starts to rotate. The crankshaft block 7 set on the center shaft 4 performs circular motion with the rotation of the center shaft 4. This circular motion is converted into up and down reciprocating motion, thereby driving the entire rammer to vibrate up and down. This design realizes the efficient conversion of the rotational motion of the motor 2 to the reciprocating motion of the rammer, ensuring the continuous and stable operation of the rammer.

[0037] See also Figure 4 As an implementation method of the positioning mechanism: a positioning mechanism is provided at the top of the fixed sleeve 11, and the positioning mechanism includes a control sleeve 28, an inner gear ring 29, a gear 30, an annular groove 31, a positioning groove 32 and a positioning block 33. The control sleeve 28 is rotatably mounted on the top of the fixed sleeve 11, and the inner gear ring 29 is arranged on the bottom surface of the control sleeve 28. The gear 30 is mounted on the top of multiple groups of screws 27 and meshes with the inner gear ring 29. The annular groove 31 is arranged in the control sleeve 28. There are multiple groups of positioning grooves 32 distributed on the outer wall of the fixed sleeve 11. The positioning block 33 is provided with multiple groups slidably mounted on the fixed sleeve 11. By rotating the control sleeve 28, multiple screws 27 can be driven simultaneously to achieve synchronous adjustment. The meshing of the inner gear ring 29 and the gear 30 provides good torque transmission, making operation easier. The setting of the annular groove 31 and the positioning block 33 provides additional positioning function, which increases the accuracy and stability of adjustment.

[0038] The top ends of the multiple groups of positioning blocks 33 extend into the annular groove 31, and push springs 34 are connected between the top ends of the multiple groups of positioning blocks 33 and the inner wall of the annular groove 31, which can ensure that the positioning blocks 33 always maintain contact with the annular groove 31, eliminate possible gaps, and improve positioning accuracy.

[0039] More specifically, when the control sleeve 28 is rotated, the inner gear ring 29 provided on the bottom surface of the control sleeve 28 drives the gear 30 meshing with it to rotate, thereby driving the screw 27 to rotate. The rotation of the screw 27 drives the transmission sleeve 24 to move up and down, realizing the precise positioning of the limit block 25. At the same time, the annular groove 31 in the control sleeve 28 cooperates with the positioning block 33, and provides additional positioning and buffering functions under the action of the push spring 34. Multiple groups of positioning grooves 32 are distributed on the outer wall of the fixed sleeve 11, and cooperate with the positioning block 33 to provide multiple positioning points, thereby increasing the accuracy and flexibility of positioning.

[0040] In summary, when the whole device is in use or running: the operator first moves the rammer to the designated position by means of the handle 18, then connects the rammer plate 8 to the housing 1 through the fixing mechanism, inserts the fixing rod 10 into the connecting block 9 and the housing 1, and then plugs the fixing sleeve 11 into the fixing rod 10. When the fixing rod 10 is inserted into the fixing sleeve 11, the cooperation between the positioning rod 20 and the positioning hole 19 further enhances the connection stability, and then the top of the fixing rod 10 pushes the top plate 17, so that the top plate 17 pushes the top plate 17 to push the top plate 17. The top block 16 is assembled, thereby pushing the multiple groups of arc rods 13 to slide along the movable hole 12, so that the clamping blocks 14 at the bottom ends of the multiple groups of arc rods 13 are clamped in the clamping groove 15 set on the outer wall of the fixed rod 10, fixing the fixed rod 10, and the limit bar 21 slides in the limit groove 22 to ensure the accuracy of the movement of the arc rod 13. When the control sleeve 28 is rotated, the inner gear ring 29 drives the gear 30 meshing with it to rotate, thereby driving the screw 27 to rotate. When the screw 27 is rotated, the transmission screw 27 threadedly connected to the screw 27 The sleeve 24 will slide up and down on the outer wall of the fixed sleeve 11. When the transmission sleeve 24 moves up, the multiple groups of limit blocks 25 installed on the top surface of the transmission sleeve 24 will enter the limit holes 26 on the arc rod 13, forming a secondary lock, thereby realizing the precise positioning of the limit blocks 25. This double locking mechanism greatly improves the stability and reliability of the connection between the ramming plate 8 and the shell 1. When it is necessary to adjust the position or replace the ramming plate 8, it is only necessary to operate the fixing mechanism and the limit mechanism to quickly complete the replacement, which greatly improves the working efficiency. Then start the motor 2. When the motor 2 is started, the driving wheel 3 installed at the output end of the motor 2 starts to rotate. The driving wheel 3 drives the driving wheel 5 to rotate through the transmission belt 6, and then the center shaft 4 starts to rotate. The crankshaft block 7 set on the center shaft 4 performs a circular motion with the rotation of the center shaft 4. This circular motion is converted into an up and down reciprocating motion, thereby driving the entire rammer to vibrate up and down. This design realizes the efficient conversion of the rotational motion of the motor 2 to the reciprocating motion of the rammer, ensuring the continuous and stable operation of the rammer.

[0041] When the control sleeve 28 is rotated, the inner gear ring 29 provided on the bottom surface of the control sleeve 28 drives the gear 30 meshing with it to rotate, thereby driving the screw 27 to rotate. The rotation of the screw 27 drives the transmission sleeve 24 to move up and down, realizing the precise positioning of the limit block 25. At the same time, the annular groove 31 in the control sleeve 28 cooperates with the positioning block 33, and provides additional positioning and buffering functions under the action of the push spring 34. Multiple groups of positioning grooves 32 are distributed on the outer wall of the fixed sleeve 11, and cooperate with the positioning block 33 to provide multiple positioning points, thereby increasing the accuracy and flexibility of positioning.
