Description

Technical Field

[0001] The utility model relates to the technical field of land leveling engineering, in particular to a tamping device for land leveling engineering. Background Art

[0002] Land leveling is an engineering project that involves changing the land topography, improving land utilization and optimizing agricultural or construction uses. When carrying out land leveling, the land needs to be compacted and tamped to ensure that the land has sufficient bearing capacity and prevent future ground subsidence. When tamping, a tamping device is needed.

[0003] In the prior art, a frog-type rammer is needed for compaction work in different usage environments and corner areas. The frog-type rammer consists of a rammer, an engine, an operating rod and an eccentric wheel. The rammer mainly utilizes the engine to drive the eccentric wheel to rotate eccentrically, so that the rammer connected thereto performs a jumping motion, and uses gravity and power to impact and compact the soil. In actual use, when tamping the soil, the requirements for compaction in different situations are also different. The greater the height of each swing of the rammer, the longer its falling time is, and the lower the work efficiency is, but the compaction degree is higher. If the compaction strength requirement is low, the compaction strength cannot be changed and the compaction rate cannot be increased, resulting in low compaction efficiency and low applicability of the device.

[0027] By means of the above structure, two transmission holes of the same size are opened at the inflection point of the V-shaped bracket 3, and the two rotating rods 4 are rotatably installed in the two transmission holes respectively. The two rotating rods 4 have the same size and are concentric, and the two rotating rods 4 are connected through the adjustment box 11. The interior of the adjustment box 11 is hollow, and the rack 14 is slidably installed in the adjustment box 11 through the limit block 15. The two limit blocks 15 can limit the rack 14 to prevent it from sliding out of the adjustment box 11.

[0033] By means of the above structure, one end of the V-shaped bracket 3 is rotatably connected to the support rod 2, and a rammer 13 is installed at the other end. The rammer 13 can facilitate compacting the soil. The primary transmission disc 5 includes two inner and outer transmission grooves. The large transmission groove close to the outer side is sleeved with a primary transmission belt 7, and the inner side close to the side of the support rod 2 is sleeved with a secondary transmission belt 9.

[0034] Furthermore, a driving motor 10 is fixedly mounted on the upper side of the base plate 1 , a driving disc 6 is fixedly mounted on the output end of the driving motor 10 , and the surface of the driving disc 6 and the surface of the primary transmission disc 5 are sleeved with the same primary transmission belt 7 .

[0035] By means of the above structure, when the driving motor 10 is started, the output end of the motor drives the driving disk 6 to rotate, the driving disk 6 drives the primary transmission disk 5 to rotate through the primary transmission belt 7, the primary transmission disk 5 drives the secondary transmission disk 8 to rotate through the secondary transmission belt 9, the secondary transmission disk 8 drives the two rotating rods 4 to rotate, the two rotating rods 4 drive the same adjustment box 11 to rotate, the adjustment box 11 drives the rack 14 to move, the rack 14 drives the eccentric wheel 12 to move, the movement of the eccentric wheel 12 causes the V-shaped bracket 3 to generate an eccentric force to swing at the point where the support rod 2 is connected, thereby driving the rammer 13 to be lifted, and the rammer 13 uses gravity and power to hit the ground to compact the ground.

[0036] Furthermore, an armrest 22 is rotatably mounted on one side of the base plate 1 .

[0037] With the above structure, the armrest 22 can push the device forward.

[0038] Working principle: when the device is in use, first start the drive motor 10, the output end of the drive motor 10 drives the drive disk 6 to rotate, the drive disk 6 drives the primary transmission disk 5 to rotate through the primary transmission belt 7, the primary transmission disk 5 drives the secondary transmission disk 8 to rotate through the secondary transmission belt 9, the secondary transmission disk 8 drives the two rotating rods 4 to rotate, the two rotating rods 4 drive the adjustment box 11 to rotate, the adjustment box 11 drives the rack 14 to move, the rack 14 drives the eccentric wheel 12 to move, the movement of the eccentric wheel 12 makes the V-shaped bracket 3 generate eccentric force to swing at the point where the support rod 2 is connected, thereby driving the rammer 13 to be lifted, and the rammer 13 uses gravity and power to hit the ground to compact the ground.

[0039] When the compacted land needs to be consolidated and compacted for the second time, that is, when the compaction strength requirement is reduced, the screw rod 21 is first rotated to separate the screw rod 21 from a threaded hole to unlock the knob 20, and then the knob 20 is manually rotated, the knob 20 drives the worm 19 to rotate, the worm 19 drives the worm wheel 18 to rotate, the worm wheel 18 drives the connecting rod 17 to rotate, the connecting rod 17 drives the gear 16 to rotate, and the gear 16 drives the rack 14 to move, so that the rack 14 moves upward and gradually shrinks into the adjustment box 11, so that the eccentric wheel 12 gradually approaches the rotating rod 4, and the swing of the eccentric wheel 12 is reduced. Radius, as the swing radius of the eccentric wheel 12 gradually decreases, the eccentric force generated by the V-shaped bracket 3 decreases, so that the lifting amplitude of the rammer 13 is reduced and it falls earlier, which increases the number of compactions in the same period while reducing the compaction strength, thereby improving the compaction rate. When the eccentric wheel 12 is adjusted to a suitable position, the screw 21 is passed through the avoidance opening and re-screwed to a threaded hole, the knob 20 is fixed, the rammer 13 is locked, and the drive motor 10 is started to perform compaction work, thereby achieving the adjustment of the compaction rate and strength of the rammer 13 and improving the applicability of the device.
