Intelligent hedge trimmer

Abstract

The invention relates to an intelligent hedge trimmer; the technical solution thereof includes that when the device moves to the left, the reciprocating cutting action of the cutter cuts off the newly-born branch forks on the fence and conveys them to the crushing tube for crushing under the action of the brush roller and the spiral blade, and finally conveys them to the roots of plants at intervals in coordination with the conveying of high-pressure gas under the telescopic action of the L-shaped tube and the branch tube. During the trimming process, the device moves continuously to the left, but the branch tube extending into the root of the plant cannot follow the continuous movement of the device due to the blocking action of the plant. Therefore, the device adopts the swing of the L-shaped tube to cooperate with the continuous movement of the whole support, so that the crushed material can be intermittently conveyed to the root of the plant while the material is continuously collected. At the same time, the L-shaped tube is equipped with an extension switch and a retraction switch at the left and right extreme positions to realize the extension and retraction of the branch tube, and the high-pressure gas pushes the material outward when the branch tube is extended.

Description

Technical Field

[0001] The invention relates to the field of gardening equipment, in particular to an intelligent hedge trimmer. Background Art

[0002] Hedge walls are a common greening method on both sides of gardens and municipal roads. The greening area is large and most of them are pruned horizontally. Especially in spring and summer every year, it is necessary to regularly pruned the new branches on the fence walls to keep them neat and beautiful. At present, the pruning method generally adopts manual hand-held electric pruning equipment with application number: 200910004769.X and patent name: hedge trimmer, or manual equipment with application number: 201610939991.9 and patent name: a hedge shear. In which the electric equipment or the manual equipment uses a horizontal cutting method to cut off the new branches of the fence wall and then collect the cut branches for similar treatment. At present, there are also pruning vehicles with application number: 201710412792.7 and patent name: an automatic hedge trimming vehicle, which can realize the pruning of the fence wall and the collection of broken branches at one time, but the above methods all collect the pruned branches and leaves as garbage collection.

[0003] It is well known that the ends of new branches of plants are the most densely populated parts of plants where growth hormones and other essential elements for plant growth are located. If the new branches are cut off and directly collected and treated as garbage, it will not only increase the cost of garbage disposal, but also be detrimental to the growth and development of plants. Therefore, if these branches can be fed back to the roots of plants after pruning, it will save the cost and time of garbage recycling and fertilize the fence, achieving the best of both worlds. However, the commonly thought of method at this stage is to open the upper end of the fence by vibration or poking, so that the cut branches fall from the upper end of the fence to the root of the fence, and in actual operation, the numerous branches on the fence wall will hinder the cut branches from falling to the roots. The suspended branches are not easy to rot and reuse when they are not in contact with the ground, and the remaining broken branches turn yellow after drying, which contrasts with the color of the fence wall, affecting the overall appearance of the fence wall.

The lower end of the crushing tube 6 is hinged There is an L-shaped tube 9, and a coil spring 10 is fixed at the lower end of the crushing tube 6, which can make the lower end of the L-shaped tube 9 swing to the left and reset. A branch tube 11 is sleeved on the horizontal tube end of the lower end of the L-shaped tube 9, and an electric cylinder 12 is fixed on the branch tube 11, which can drive it to extend and retract in the horizontal tube at the lower end of the L-shaped tube 9. An air pipe 13 is provided on the front side of the horizontal tube end of the L-shaped tube 9, and the other end of the air pipe 13 is connected to a high-pressure air source. An extension switch 14 of the electric cylinder 12 is provided on the left side of the bracket 1, and a contraction switch 15 of the electric cylinder 12 is provided on the right side of the bracket 1. A gas supply switch 16 of a high-pressure gas source is provided on the right side of the bracket 1. When the lower end of the L-shaped tube 9 swings to the right, it first contacts the gas supply switch 16 and then contacts the contraction switch 15, and the gas supply switch 16 can be continuously compressed.

[0022] In order to facilitate the movement and driving of the bracket 1, the bracket 1 includes a crossbeam, the tool 2 is fixed on the crossbeam, two legs are hinged on the front side of the crossbeam, a roller is rotatably installed on the free end of each leg, the crushing tube 6 is placed between the two legs, a handrail 17 is fixed on the upper end of the crossbeam, and the extension switch 14, the contraction switch 15 and the air supply switch 16 are all fixed on the corresponding legs through connecting rods.

[0023] In order to facilitate the up and down adjustment of the bracket 1, a threaded rod 18 is hinged on the inner side of each leg, and a double-headed threaded tube 19 is provided between the two threaded rods 18. The free ends of the two threaded rods 18 are respectively screwed on the corresponding ends of the threaded tube 19. Rotating the threaded tube 19 can make the two threaded rods 18 move toward or away from each other synchronously.

[0024] In order to realize the driving and installation of the tool 2, the front end of the tool 2 located at the lower end is fixed on the bracket 1, the tool 2 located at the lower end is provided with a slide groove in the front and rear directions, and the tool 2 located at the upper end is installed with a slider. The tools 2 at the upper and lower ends are slidably installed through the slide groove and the slider. A reciprocating motor is provided on the bracket 1, and the output shaft of the reciprocating motor is fixed on the tool 2 located at the upper end.

[0025] In order to facilitate the driving of the brush roller 4 and the spiral blade 8, a first pulley 20 is coaxially fixed to the front and rear of the brush roller 4, and a second pulley 21 is coaxially installed after the core shaft of the spiral blade 8 passes through and extends out of the crushing tube 6. The first pulley 20 is connected to the second pulley 21 via a belt, and the second pulley 21 is driven by a first motor fixed to the bracket 1.

[0026] In order to facilitate the installation of the high-pressure gas source, the high-pressure gas source is a high-pressure gas cylinder 22, which is installed on the bracket 1, and the air pipe 13 is connected to the L-shaped pipe 9 to install an extension pipe, and a nozzle is installed in the extension pipe.

[0027] In order to facilitate the L-shaped tube 9 to touch the ground when swinging, the vertical tube end of the L-shaped tube 9 is a telescopic tube, and a spring 23 is sleeved on the telescopic tube to reset it.

[0028] In order to install the crushing tube 6, the crushing tube 6 is a U-shaped tube, and a guide plate 24 is provided inside the bending part of the U-shaped tube.

[0029] In order to prevent branches and leaves from being stuck to the bristles of the brush roller 4 when the brush roller 4 rotates, comb teeth 25 are provided at the upper end of the left opening of the arc-shaped housing 5 , and the bristles of the brush roller 4 pass through the comb teeth 25 .

[0030] The specific working process of the present invention is as follows: when the device is in use, the threaded tube 19 is adjusted so that the interval between the two legs is maintained at an appropriate distance. At this time, the lower edge of the cutter 2 is kept parallel to the end face of the hedge trimmed. Under the reset action of the coil spring 10, the L-shaped tube 9 is pushed close to the left leg and contacts and squeezes the extension switch 14. At this time, under the control of the extension switch 14, the electric cylinder 12 is in an extended state, and the bracket 1 is moved toward the fence direction so that the branch pipe 11 driven by the extended electric cylinder 12 is inserted into the position of the inner side of the lower end of the fence near the root of the hedge plant. At this time, the reciprocating motor is turned on to make the cutter 2 reciprocate. The device can move to trim the new branches when it moves to the left, and at the same time, turn on the first motor, so that the brush roller 4 and the spiral blade 8 can be rotated under the drive of the first motor through the first pulley 20 and the second pulley 21. In this process, the branches and leaves trimmed by the tool 2 when the device moves to the left can be transported into the arc-shaped shell 5 through the brush roller 4, and enter the crushing tube 6 driven by the spiral blade 8. The branches entering the crushing tube 6 are crushed by the crusher 7, and the crushed materials slide into the L-shaped tube 9 under the action of the guide plate 24.

[0031] As the device as a whole moves to the left, the branch pipe 11 extends the horizontal pipe end of the lower end of the L-shaped tube 9 under the extension effect of the electric cylinder 12, so that it is inserted into the root of the fence plant and blocked by it. Therefore, when the device as a whole moves horizontally to the left, the lower end of the L-shaped tube 9 cannot move with the device due to the blocking effect of the plant. During this process, the L-shaped tube 9 rotates around its hinge axis, and the coil spring 10 is compressed during this process. During the swinging process of the L-shaped tube 9, its vertical tube end is a telescopic tube that can adaptively extend and retract under the action of the spring 23. As the device continues to move, the L-shaped tube 9 gradually contacts the gas supply switch 16. The gas supply switch 16 is squeezed so that the gas in the high-pressure gas cylinder 22 is connected to the horizontal tube end of the L-shaped tube 9. Under the action of the airflow, the material in the horizontal tube of the L-shaped tube 9 passes through the branch pipe 11 Blown to the roots of the fence plants, as the device continues to move left, the air supply switch 16 is continuously pressed, and the pressure rod on the air supply switch 16 has a compression margin. In order to realize that the air supply switch 16 has a compression margin, its contact rod can be a telescopic rod, and the telescopic rod is provided with a reset compression spring. The device continues to move left until the L-shaped tube 9 contacts and squeezes the retraction switch. At this time, the electric cylinder 12 drives the branch pipe 11 to retract into the horizontal tube of the L-shaped tube 9. After retraction, the L-shaped tube 9 is no longer blocked by the roots of the plants. Under the reset of the coil spring 10, the L-shaped tube 9 is quickly swung and reset, and the extension switch 14 is re-contacted. Driven by the electric cylinder 12, the branch pipe 11 is re-extended and inserted into the roots of the fence plants. As the device continues to move, the crushed materials are intermittently distributed in piles at the roots of the fence, which is convenient for subsequent rotting and fermentation to replenish the fence.

[0032] Compared with traditional equipment, this device has the following advantages:

[0033] 1. When the device moves to the left, the reciprocating cutting action of the cutter cuts off the new branches on the fence and transports them to the crushing tube 6 for crushing under the action of the brush roller 4 and the spiral blade 8. Finally, under the telescopic action of the L-shaped tube 9 and the branch tube 11, the high-pressure gas is transported to the roots of the plants at intervals to facilitate the subsequent composting.

[0034] 2. During the pruning process, the device continues to move to the left, but the branch pipe 11 extending into the root of the plant cannot follow the continuous movement of the device due to the obstruction of the plant. Therefore, the device adopts the swing of the L-shaped tube 9 to cooperate with the overall continuous movement of the bracket 1, so that the material can be intermittently crushed and transported to the root of the plant while being continuously collected. At the same time, the L-shaped tube 9 is installed with an extension switch 14 and a retraction switch at the left and right extreme positions to realize the extension and retraction of the branch pipe 11, and the high-pressure gas is used to push the material outward when the branch pipe 11 is extended, so that the entire crushed material can be efficiently and orderly transported to the root of the plant.

[0035] 3. In this device, the newly grown branches are broken before being fed back to the plants as waste, making it easier for the materials to be degraded and fermented by microorganisms. The materials are transported to the roots from one side through a pipe, which can effectively avoid the problem of materials falling and causing the branches to dry up, forming a contrast between the withered and flourishing of the fence, and reducing the aesthetics of the fence.
