Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 1 and 2, the self-propelled mutual compensation lawn compactor comprises a frame 10, a driving device 11 arranged at the head of the frame 10, and a traveling wheel set arranged at the bottom of the frame 10 and used for driving the frame 10 to travel by rolling and compacting lawns; the wheel surface of the walking wheel set is a smooth curved surface, the walking wheel set comprises two front wheels 21 and two rear wheels 22, the two front wheels 21 are coaxially arranged at intervals and installed on two sides of the front end of the rack 10, and the rear wheels 22 are installed at the rear end of the rack 10 and correspond to the interval length positions formed between the two front wheels 21 so as to compensate and compact the non-compacted parts of the two front wheels 21. It can be understood by those skilled in the art that the driving device 11 is a diesel engine and a matching transmission mechanism, and has the same structure as a common walking tractor, two sides of the bottom of the frame 10 are provided with rotating shafts which are connected with the front wheels 21, the rotating shafts are fixedly provided with transmission wheels, and an output shaft of the diesel engine is in transmission connection with the transmission wheels through a belt so as to drive the front wheels 21 to rotate, so that the frame 10 can walk and compact the lawn through a walking wheel set.

As shown in fig. 3, during operation of the lawn compactor, the front wheels 21 are mounted so that a large distance exists between the two front wheels 21, so that they cannot all be pressed, and the two end faces of the rear wheel 22 are in the same plane as the end faces of the two front wheels 21, as shown by the broken lines in fig. 3, so that the rear wheel 22 can be used to compensate for the compaction of the non-compacted parts of the two front wheels 21 during operation; and the two front wheels 21 and the rear wheel 22 form a three-point supporting structure, so that the stability of the compactor can be maintained.

The utility model discloses a lawn compactor installs two front wheels 21 and a rear wheel 22 directly in frame 10 bottom, and two front wheels 21 and a rear wheel 22 form stable triangle-shaped relation in the position, can guarantee that frame 10 is steady walking under drive arrangement 11's drive, and the walking wheelset is different from ordinary wheel, and its wheel face is smooth curved surface, in addition the dead weight of compactor itself, can carry out the compaction to the lawn in the gardens when walking; and the installation position of the rear wheel 22 corresponds to the interval formed between the two front wheels 21, and the uncompacted part of the front wheels 21 can be compacted in a compensation manner, so that after the compactor passes once, the walking area can be compacted, the compacting effect is good, the flatness is high, and the appearance is attractive.

To further improve the maneuverability and steering of the compactor, the frame 10 further includes a tail-mounted carriage 12, as shown in FIG. 1, one end of the carriage 12 pivotally connected to the frame 10 by a pin, and the rear wheel 22 pivotally mounted to the bottom of the carriage 12. It can be understood by those skilled in the art that a rotary connecting seat is provided at the connecting portion of the towing bracket 12 and the rear wheel 22, and a protruding shaft rod corresponding to the connecting seat is provided at both ends of the rear wheel 22, and the shaft rod is rotatably connected with the connecting seat through a bearing. Because of the relatively complex shape in the garden and the low regularity of the lawn, there are few straight sides, and thus a controlled steering function is required for the compactor, the steering of the compactor can be easily achieved by arranging the rear wheels 22 as independent following wheels after the rear wheels 22 are mounted on the carriage 12. In addition, the compactor is small in size and flexible to operate, so that the compactor is not only suitable for gardens, but also suitable for lawn compaction work in other occasions.

As shown in fig. 1, a water tank 13 is installed on the top of the carriage 12, a sprinkler head 14 is installed on the front end of the frame 10, the sprinkler head 14 is disposed on the front end of the front wheel 21, the sprinkler head 14 is communicated with the lower end of the water tank 13 through a pipe 141, the sprinkler head 14 is located lower than the connection end of the sprinkler head 14 and the water tank 13, and the lower portion of the sprinkler head 14 is provided with uniform water spraying holes 142. When the compactor carries out the compaction, the water of splendid attire naturally passes through pipeline 141 under the pressure effect and spouts from sprinkler bead 14 in the water tank 13, and then wets the lawn before the compaction of front wheel 21, makes the soil of lawn bottom combine more easily with the soil of original bottom surface, and then improves the degree of compaction, and just so just the compaction of spraying water has improved compaction efficiency greatly, avoids the inefficiency of artifical water spray and easily steps on the problem on lawn.

To ensure the degree of wetting, the sprinkler head 14 is tubular and the two ends of the sprinkler head 14 are flush with the outer end of the front wheel 21, as shown in fig. 1, so that the sprinkler head 14 can completely cover the compaction width of the road wheel set, and the lawn can be wetted before compaction, thereby improving the compaction degree.

As shown in fig. 1, a control valve 15 is disposed on a pipe 141 connecting the sprinkler head 14 and the water tank 13, and the control valve 15 is fixedly installed at the front end of the carriage 12, so that an operator can freely control the opening and closing of the sprinkler head 14 and the water output at the carriage 12.

As shown in FIG. 1, the front end of the water tank 13 is provided with a protruding portion 16 to form a seat, and the water tank 13 is used as a water storage tool and a driving seat, so that an operator can sit on the protruding portion 16 at the front end of the water tank 13 to operate the compactor, and the comfort of the operator is greatly improved.

In order to further improve the compaction degree of the compactor, as shown in fig. 1, a clamping portion 17 is further arranged at the bottom of the carriage 12 behind the rear wheel 22, the clamping portion 17 is symmetrically arranged at two sides of the frame 10, the clamping portion 17 at two sides is flush with the outer end face of the front wheel 21, an auxiliary compaction wheel 23 is arranged between the clamping portion 17 at two sides, two end faces of the auxiliary compaction wheel 23 are provided with protruding connecting shafts 231, clamping bearings 232 are arranged on the connecting shafts 231, and the clamping bearings 232 are clamped in the clamping portion 17. The joint portion 17 makes supplementary compaction wheel 23 cover the compacting face of front wheel 21 and rear wheel 22 completely with the outside terminal surface parallel and level of front wheel 21, supplementary compaction wheel 23 can carry out the compaction once more as the lawn that secondary compaction wheel pair had already been compacted like this, and supplementary compaction wheel 23 passes through joint bearing 232 and joint portion 17's cooperation joint in the carriage 12 bottom, can realize freely dismantling like this, be convenient for decide whether to install supplementary compaction wheel 23 according to the operating requirement of difference, improve the practicality and the application scope of compactor. As will be understood by those skilled in the art, since the auxiliary compactor 23 and the rear wheel 22 are both mounted at the bottom of the carriage 12, and the top of the auxiliary compactor 23 and the rear wheel 22 will protrude beyond the top surface of the carriage 12, the carriage 12 is made of steel frame, and the bottom of the water tank 13 is arched at the positions corresponding to the auxiliary compactor 23 and the rear wheel 22, so as to avoid interfering with the operation of the auxiliary compactor 23 and the rear wheel 22.
