Description

A leisure and fitness type skateboard lawnmower

technical field

The invention relates to a lawnmower, which belongs to the field of garden pruning.

Background technique

With the strengthening of people's awareness of environmental protection, the area of lawns and other related gardens has increased significantly. A lawnmower is a mechanical tool used to trim lawns, vegetation, etc. Most of the lawnmowers currently on the market need a power engine, which has the following problems: 1. The power engine will generate a lot of noise, which will bring environmental pollution. pollute. In places of office and study, this kind of lawnmower that needs a power engine is very unpopular; 2. Since the power is the engine, the maintenance and maintenance costs of the power unit of the lawnmower are relatively high; 3. This type of grass cutting When the machine is in operation, it will also bring strong vibrations to the staff, making the operation very uncomfortable; 4. Because this type of lawnmower includes complex structures such as blade assembly, power assembly, and installation mechanism, it often takes up a large area 5. Although the power engine makes the mowing efficiency of the lawnmower higher and the mowing effect is better, its price is also more expensive. For now, the average user is unacceptable.

Contents of the invention

The purpose of the present invention is to overcome the related problems of existing lawnmowers, and provide a kind of leisure and fitness skateboard type lawnmower. Noise pollution, light and simple, easy to operate, beautiful and practical effect, and suitable for general users. The present invention is realized through the following technical solutions:

The invention provides a leisure and fitness type skateboard lawnmower. The lawnmower is divided into three parts: a transmission structure, a speed-increasing structure and a cutter structure. The transmission structure includes a front wheel, a rear wheel, a driving shaft, and a driving shaft gears, push rods and slide plates; the speed-increasing structure includes the intermediate shaft, the gear at the middle position on the intermediate shaft, the first gear and the second gear at both ends of the intermediate shaft; the tool structure includes the tool shaft, the gears at both ends of the tool shaft The third gear, the fourth gear, and the hob, the gear on the driving shaft and the gear in the middle position on the intermediate shaft form the first-stage speed-up gear pair, and the first gear at both ends of the intermediate shaft and the tool shaft are two The third gear at the end position, the fourth gear at both ends of the tool shaft and the second gear at both ends of the intermediate shaft form the second-stage speed-up gear pair, the top cover and the bottom cover form the installation space, and the push rod passes through the movable pin and The top cover is connected, and the skateboard is connected with the bottom cover through movable pins, so that the skateboard lawnmower can reduce the occupied volume by putting the push rod down when storing, and can flexibly control the forward movement by changing the direction of the skateboard during travel direction, the rear of the skateboard is equipped with rear wheels. The front wheel can be used as a source of driving torque for the lawnmower without an engine, and the front wheel can be rotated by sliding the slide plate or pushing the push rod forward. Combined. The speed-up structure can realize two-stage speed-up, so that the cutter shaft drives the hob to rotate at a high speed. The cutter structure adopts the form of a hob, that is, the principle of relative movement of two blades is easier to cut the grass.

The working principle of the skateboard lawnmower is as follows: when the lawnmower is working, people step on the skateboard or push the push rod to walk, so that the front wheels of the lawnmower rotate, and the driving torque of the front wheels is transmitted to the lawnmower through the drive shaft. on the gear of the drive shaft,

Further, the first speed-up is performed through the first-stage speed-up gear pair, so that the speed of the intermediate shaft is greater than the speed of the drive shaft, and the driving torque on the drive shaft is transmitted through the first-stage speed-up gear pair to the intermediate shaft.

Further, the drive torque on the intermediate shaft is transmitted to the cutter shaft through the second-stage speed-up gear pair, and at the same time, the lawnmower performs a second speed-up through the second-stage speed-up gear pair, so that the cutter shaft can Rotate at a higher speed.

Further, the cutter shaft drives the hob to rotate at a high speed, so that the grass in front of the lawnmower enters the hob through the groove in front of the bottom cover for cutting, and the cut grass is thrown into the bottom of the bottom cover, and passes through the opening at the bottom of the bottom cover. The square groove leaves the mower, and the mowing action is completed.

Positive effects that can be achieved by adopting the technical solution of the present invention: the lawnmower uses a unique driving method to combine the skateboard with the lawnmower, so that people can combine grass cutting work with leisure and fitness, and the lawnmower has no engine drive , No noise pollution, light and simple, easy to operate, beautiful and practical, and suitable for general users.

The invention connects the lawn mower with the skateboard, realizes the effect of leisure and fitness while realizing the grass cutting function, and is energy-saving and environment-friendly.

detailed description

In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Fig. 1 and Fig. 2, a kind of leisure fitness type skateboard type lawnmower provided by the present invention, transmission structure comprises front wheel (13), the gear (3) on the drive shaft (14), the rear wheel (15), push rod (1) and slide plate (16); the speed-increasing structure includes the intermediate shaft (5), the gear (7) at the middle position on the intermediate shaft, the first gear (4) and the second gear at both ends of the intermediate shaft Two gears (12); the tool structure includes the third gear (6) and the fourth gear (11) at the two ends of the tool shaft (8), the tool shaft, hob (10), top cover (2) and bottom cover ( 9) Form the installation space, the push rod (1) is connected with the top cover (2) through the movable pin (17), and the slide plate (16) is connected with the bottom cover (9) through the movable pin (18), so that the skateboard lawn mower During storage, the occupied volume can be reduced by putting the push rod (1) down, and the direction of advancement can be flexibly controlled by changing the direction of the skateboard (16) during travel. The rear wheel (15 ). The power source of the skateboard lawnmower is accomplished by driving the front wheel (13), and the speed-up structure can realize two-stage speed-up, so that the cutter shaft drives the hob to rotate at a high speed. The cutter structure adopts the form of a hob, that is, the principle of relative movement of two blades is easier to cut the grass.
