Description

Intelligent multi-functional lawn mower

technical field

The invention relates to the technical field of urban greening, in particular to an intelligent multifunctional lawnmower.

Background technique

Developing agricultural mechanization, improving work efficiency, and improving agricultural production efficiency are particularly important in a large agricultural country like ours. Lawn mowers play an important role in agricultural production and have a direct impact on crop yields. It is a human invention. a big progress.

With the continuous progress of society, the use of lawn mowers has become more and more extensive, and it is not limited to agricultural production, especially for urban greening plants, lawns, playgrounds and other fields, lawn mowers have already occupied a dominant position. In urban greening, lawn mowers are needed for repairing and cutting lawns. In urban life, lawn planting areas are getting wider and larger, and the lawns of football fields make it more important in urban greening. Lawn mowers have become particularly important. If you rely on manual trimming, a lot of labor and time will be wasted, so for large areas and large quantities of lawns, lawn mowers have completely replaced manual trimming.

The current lawn mower is also called weeder, lawn mower, lawn trimmer, etc. The lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, It is composed of blade, armrest and control part. This existing lawnmower mechanism is relatively simple, and function is single, and only with respect to artificial machinery, this lawnmower has improved efficiency.

However, when greening urban lawns, existing lawnmowers have many deficiencies, which can no longer meet the needs of urban greening. These deficiencies have become a new technical problem, and it is urgent to find a new technical solution to solve them. .

1. Existing lawn mowers need to manually support the handle and manually control the direction. For hot summer or rainy days, it is a torment for the operator to operate outdoors, and the lawn mower is not fully intelligent.

2. For large-scale lawns, manual operation cannot keep the direction of the mower in a straight line when mowing. Usually, when you walk for a while and look back, the walking route has deviated from the original straight-line track. Not a small problem, especially for large lawns or football fields. First, after the track deviates, there will be repeated pruning in some areas, which wastes resources. Second, when repeated pruning occurs, the height of the lawn will be inconsistent and the cutting will not Leveling, and the football field has strict requirements for the lawn. Third, after the track deviates, it needs to waste a lot of time and labor to correct the part.

3. Because when mowing urban greening with a lawn mower, generally sanitation workers are used, and when mowing the lawn, there are male and female sanitation workers, but the heights of male and female sanitation workers are different. The height of a single lawn mower handrail makes men, women It is very inconvenient for female sanitation workers to use.

4. Existing lawn mowers can only mow the grass, but cannot crush and collect the grass. After each mowing, the grass needs to be collected manually, which is time-consuming and laborious, and the work efficiency is low.

5. After the grass is crushed and collected, the lawn mower should be cleaned from time to time, otherwise a large number of weeds and flying insects will remain in the lawn mower, which will breed a lot of bacteria and flying insects, pollute the lawn mower, and produce odor gas at the same time.

6. There is no reminder device in the collection box. It is necessary to observe whether the collection box is full from time to time. Once the collection box is full, weeds are kept inward, which may overload the motor and damage the lawn mower.

7. In order to ensure that the lawn is trimmed evenly, it is often necessary to trim the lawn repeatedly, which wastes a lot of time and low work efficiency, and it is impossible to trim the lawn once.

8. For the collection box of the lawn mower, there should not only be a reminder device, but also an overload protection device, otherwise it is easy to damage the driving equipment.

9. When the lawn mower is trimming, it relies on the rotation of the powerful blade to trim the lawn, but in actual operation, many weeds will fall on the ground, and the lawn mower does not trim it when it passes by. Secondly, if the weeds are trimmed without exerting a certain grasping force on the weeds, the weeds will fall forward, which is often difficult to trim, and eventually the height of the trimmed lawn will be inconsistent, which is more vivid. It is said that when mowing the grass manually, it is often necessary to hold the top of the weed with one hand and cut the weed with the other hand, that is to say, it is necessary to exert a certain grasping force on the weed to ensure that the weed is cut. When cutting evenly, do not miss any weeds, and ensure that all weeds are cut at the same height.

Therefore, the present invention provides a perfect and multi-functional lawnmower, which makes each mechanism interrelated and restricts each other, and is indispensable, rather than a multi-functional lawn mower that exists alone.

First of all, there are many motors mentioned in the present invention. Although the names of the motors are the same, no detailed distinction is made. Of course, there may be motors, second motors... etc. What the inventor wants to declare is the , The second motor... are just ordinary motors, the motor is not the focus of the mechanism, it is only used to drive the rotation, and there is no special meaning, just understand it as an ordinary motor drive.

When the present invention uses, now do detailed analysis introduction with regard to concrete structure of the present invention and specific embodiment:

For the existing many lawn mowers mentioned in the background technology that need to be manually cut or manually cut, the present invention proposes a fully automated mechanical lawn mower, which is convenient for workers to operate and has fast cutting efficiency. The lawn mower with simple operation, the specific drive device is that the chassis frame 1 relies on the power drive device to realize automatic walking, and does not need to rely on manual thrust to walk. The engine 73 drives the sixth gear 74 to rotate, and the sixth gear 74 drives the transition gear 75 to rotate. 75 drives the seventh gear 76 to rotate, the seventh gear 76 drives the second connecting shaft 72 to rotate, the second connecting shaft 72 drives the rear end universal wheel 3 to rotate, the second connecting shaft 72 drives the third gear 77 to rotate, the third gear 77 The chain 78 drives the fourth gear 79 to rotate, the fourth gear 79 drives the first connecting shaft 71 to rotate, and the first connecting shaft 71 drives the front end universal wheel 3 to rotate, so the lawn mower automatically moves forward, replacing the artificial thrust. Greatly improved work efficiency.

For the problem that the existing lawnmowers mentioned in the background technology cannot always keep a straight line, the present invention can realize intelligent automation, and can realize automatic walking and always keep a straight line cutting without manual control of the direction, which is difficult to use in rainy weather. It is particularly important, and workers can do other work while automatically mowing, which saves a lot of time and improves work efficiency. In rainy weather, it is convenient for workers to mow normally. The direction meter 5 is designed and refitted by the inventor. At first, a compass 6 is provided in the direction meter 5. The same as the traditional compass principle, the compass 6 can automatically rotate and identify the direction following the change of the direction magnetic field, and the vertical needle 7 integrally connected with the compass 6 is also Follow the rotation of the compass 6, so the compass 6 always points to the north-south direction, the vertical needle 7 points to the east-west direction, and the infrared emitter 8 inside it also points to the east-west, north-south direction all the time. Before the mower works, the movement of the mower is selected direction, and then open the switch of a certain corresponding direction infrared transmitter 8 with a switch, for example, now the mower will mow eastward, then only need to open the infrared sensor 8 pointing to the east on the vertical needle 7 with a switch, at this time Let the lawnmower travel eastward automatically, once the direction deviation occurs in the lawnmower, for example, the lawnmower deviates to the north, then the infrared emitter 5 on the north side of the collection box 4 irradiates the lawnmower, and the infrared emitter 5 The signal is transmitted to the infrared receiver 9, and then the signal is transmitted to the electromagnet 13 on the upper end of the south side front end universal wheel 3. The electromagnet 13 is always powered on at the beginning. Once the signal is received, the electromagnet 13 is powered off. The metal plate 11 moves downward following the friction pad 10, so that the universal wheel 3 at the front end of the south side of the lawn mower decelerates, while the universal wheel 3 at the front end of the north side maintains the original speed, and the lawn mower moves southward. When the device 5 does not sense the lawnmower, the infrared receiver 9 sends a signal to the electromagnet 13 to energize the electromagnet 13, and the electromagnet 13 absorbs the metal plate 11 and the friction pad 10 to separate from the universal wheel 3, so that the lawnmower keeps moving in a straight line. The first spring 12 is used to buffer the adsorption and disengagement of the electromagnet 13 to the metal plate 11, because the electromagnet 13 will often absorb and disengage the metal plate 11, in order to reduce the collision between the electromagnet 13 and the metal plate 11, the first spring 12 can play a very good protective effect. In addition, the infrared transmitter 5 can realize the turning problem of the lawnmower on both sides of the chassis frame 1 with the electromagnet 13 controlled. Existing lawnmowers do not have automatic The mechanism for adjusting the direction requires manual control of the direction to operate. The structure for automatically changing the direction of the lawnmower in the present invention is not an arbitrary combination of mechanisms, and there is no problem of combination. All mechanisms are closely related and complement each other. Therefore, one mechanism cannot be taken out for a single comparison, especially in terms of creativity, and a single mechanism such as an electromagnet, a compass, and an infrared sensor cannot be used for comparison, but the ingenuity of the mechanism should be reflected as a whole.

For the lawn mower in the background technology, the lawn needs to be reciprocally trimmed. There is a slide rail 14 on the chassis frame 1, and the slide rail frame 15 moves on the slide rail 14. There are two runners 17 in the slide rail 14. The driving method It can be driven by a motor, and the two runners 17 are driven by the motor. The push pin 19 on the conveyor belt 16 moves forward with the conveyor belt 16. The push pin 19 is in the rectangular hole 18 of the slide rail frame 15, and there is a cutting motor above the slide rail frame 15. 20. The cutting motor 20 drives the cutting saw blade 21 to rotate. At this time, the push pin moves forward in the rectangular hole, and the cutting saw blade will cut in place in the starting direction. For one end time, when the push pin 19 follows the conveyor belt 16 and moves to the rectangular hole 18 When the end is at the end, it drives the slide rail frame 15 to move forward, and now the cutting saw blade 21 also moves forward while cutting, that is to say, the cutting saw blade 21 cuts while moving, and when the push pin 19 moves at the end, The push pin 19 moves laterally with the conveyor belt 16, and then moves in the opposite direction from the other side conveyor belt 16. At this time, the slide rail frame 15 stays at the end for a period of time. When the push pin 19 touches the end of the slide rail frame 15, the slide rail The frame 15 starts to move in the opposite direction, and the cutting saw blade 21 also moves in the opposite direction, and finally completes a reciprocating motion. Therefore, the movement track of the cutting saw blade 21 is: stop at the beginning and cut----follow the motion to cut---- End stay cutting----reverse motion cutting----beginning stay cutting. Compared with the traditional cutting method, the advantage of this kind of cutting is that the reciprocating cutting of the lawn can be completed while moving, which greatly improves the cutting efficiency. After the cutting is completed, the lawn will become a flat lawn. The heavier point is , the reciprocating motion is the main reason for the unevenness of the starting end and the terminal end, so the present invention stops and cuts at the starting end and the end end to ensure that after cutting by the cutting machine, the lawn at the beginning end and the end end is flat, fully ensuring that all lawns are in the All turf is guaranteed to be level after one cut.

For the existing mowers mentioned in the background technology all rely on the cutting force to cut the grass when cutting, instead of having a certain grasping force on the grass when cutting like manual cutting, this leads to When cutting the grass, some lodging grass is not cut or the grass is cut unevenly. The present invention uses four mechanisms to grab the grass. First, the first cylinder 22 shrinks and pulls the first sliding piece 23 to move inwardly. The first sliding piece 23 through the first connecting rod 24, the first grasping pieces 25 on both sides are tightened inwardly, and the grasping of the lower end of the lawn is completed, that is, it is fixed at the lower end of the lawn, and then the second cylinder 26 at the upper end shrinks, Drive the double-sided rack 27 to move to the rear end, the double-sided rack 27 drives the first gear 28 to rotate, the first gear 28 coaxially drives the second gear 29 to rotate, and the second gear 29 drives the two sliding racks 30 to move toward each other , so that the two sliding racks 30 are more and more clamped, and then the upper grabbing device 100 is fixed to the lawn. This fixation is the most important fixation, because when the grass is cut, the upper part of the grass needs to be fixed. Cutting saw blade 21 just can cut powerfully when cutting like this, and upper end grabbing device 100 is different from lower end grabbing device 99 again, at first lower end grabbing device 99 is under the fixing force effect of grass itself grass root, only needs to gently It can be fixed, so the first grabbing piece 25 of the lower end grabbing device 99 grabs at an angle when it is fixed, and only needs to grab the lawn. The grabbing is not so accurate, but the upper end grabs The device 100 is particularly important, so the second grabbing piece 33 is tightly fitted and fixed when grabbing the grass, without any gap in the middle, so that the cutting saw blade 21 has a good fixing force when cutting the grass , which is equivalent to the fixed force that is grasped by hand during manual cutting. This force is particularly important for cutting the lawn. The third mechanism is the vertical second conveyor belt 33 on both sides of the cutting saw blade 21 front. The moving direction of the two conveyor belts 33 is towards the cutting saw blade 21 direction, and the grass will follow the conveyor belt 33 to move to the cutting direction, so that the cutting saw blade 21 can cut off the grass more favorably. The inlet pipe 34 is provided with an exhaust fan 35 inside the inlet pipe 34. The exhaust fan 35 can absorb the grass, and further adsorb the grass on the inlet pipe 34, so that the cutting saw blade 21 is more powerful when cutting grass. The present invention completes the problem encountered when cutting grass through four ways, that is, when cutting grass, the grass is not carried out a certain upward grasping force, and finally the cutting of grass is uneven, or we can Just imagine that when manual cutting, why is the action of left-handed grasping and right-handed cutting, so that it can be easily solved. These four structures of the present invention firstly solve the problem, which is not solved by all lawn mowers now, and the four types The structure realizes the positioning of the grass in four different directions, and the positioning method and structure are completely different, but the structure is designed through different directions and different functions, so the technical problems and technical solutions to be solved cannot be ignored.

For the problem that the existing lawnmower mentioned in the background technology cannot be crushed and collected, because the cutting saw blade 21 is moving, the storage pipe 34 will follow the movement, so the storage pipe 34 passes through the third slide rail 84 and The upper cover 2 is connected to realize the movement, and the storage pipe 34 is connected with a scalable elastic telescopic pipe 36 to ensure that the movement of the entire cutting saw blade 21 will not cause problems such as misalignment. After entering the drum 37, it is pulverized by the auger 47 and falls into the collection box 4.

For the problem that it cannot be cleaned after mowing mentioned in the background technology, a plurality of dense holes 38 are provided on the drum 37, and the drum 37 can realize rotation.
