Description

TECHNICAL FIELD

[0001] The utility model relates to the lawn mower technical field, concretely is a lawn mower grass collecting bag closing device. BACKGROUND

[0002] With the acceleration of urbanization process and the improvement of people's requirement to the beautiful degree of living environment, lawn maintenance work becomes increasingly important. As the main tool of lawn maintenance, the optimization of performance and function of the lawn mower plays a key role in improving the efficiency and quality of lawn maintenance. Among the many functional components of the lawn mower, the closing device of the grass collecting bag is an important part that cannot be ignored.

[0003] For example, the announcement number CN207802783U discloses a lawn mower with a grass collecting bag, which includes a frame, a transmission part, a cutter disc part and a walking part. The rear part of the frame is also provided with a rear standing assembly and a backrest assembly. The frame is also connected with a box-type grass collecting bag, which includes a grass collecting port. The grass collecting port is opposite to the cutter disc part. The lawn mower also includes a cutter disc height adjusting part, which includes a lifting handle connected with a lifting shaft welding piece. The lifting shaft welding piece is installed on the frame by a shaft. A guide chain hole I is provided on the lifting shaft welding piece. One end of the lifting guide chain I is located in the guide chain hole, and the other end is connected with the cutter disc part. The height adjusting assembly also includes a locking pin assembly for fixing the height of the cutter disc part. The lawn mower has the advantages of convenient adjustment, low labor intensity and easy use. However, the traditional grass collecting bag of the lawn mower often uses a simple closing method after collecting grass clippings. For example, some grass collecting bags are tied with a rope to realize closing. This method is complicated to operate, and the operator needs to manually loop the rope around the opening of the grass collecting bag and tie a knot, which consumes time and effort. Especially in the case of frequent mowing operations and the need for multiple closings, it will greatly reduce the work efficiency. Some lawn mower grass collecting bags use clips or buckles for closing. Although this method is simpler in operation than tying with a rope, it still has many problems. The clips or buckles are easily damaged due to frequent opening and closing during long-term use, resulting in loss of clamping function. At the same time, the applicability of the clips or buckles is limited for grass collecting bags of different materials and thicknesses, and they may not provide enough clamping force, which may also cause grass clippings to leak. Therefore, it is urgent to design a lawn mower grass collecting bag closing device to solve the above problems. SUMMARY

[0004] The utility model discloses a purpose at providing a mower grass bag closing device to solve the traditional mower grass bag in the collection of grass clippings, often adopts relatively simple closing mode.

Some mower grass bags use clips or buckles for closing. Although this type of closing method is simpler than the rope binding method in terms of operation, it still has many problems. The clips or buckles are easily damaged due to frequent opening and closing during long-term use, resulting in loss of clamping function. At the same time, the applicability of the clips or buckles is limited for grass bags of different materials and thicknesses, and may not provide sufficient clamping force, which may also cause grass clippings to leak.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a mower grass bag closing device, comprising a grass collecting box, the inside upper and lower walls of the grass collecting box are both installed with guide rails, the front end of the grass collecting box is installed with a clamping mechanism, the clamping mechanism comprises a left clamping block and a right clamping block, the right wall of the left clamping block is installed with an encapsulating piece.

[0006] Preferably, two groups of L-shaped blocks are fixedly arranged on the upper and lower walls of the front end of the grass collecting box, an outer cover is installed at the rear end top side of the grass collecting box.

[0007] Preferably, left sliding blocks are fixedly arranged on the upper and lower ends of the left clamping block, a left screw cylinder is fixedly arranged at the center of the left sliding block at the top end of the left clamping block.

[0008] Preferably, right sliding blocks are fixedly arranged on the upper and lower ends of the right clamping block, a right screw cylinder is fixedly arranged at the center of the right sliding block at the top end of the right clamping block, and a fixed block is fixedly arranged at the front end of the right clamping block.
