Description

Technical Field

[0001] This utility model relates to the field of grass combing machine technology, and more specifically, to an electric grass combing machine. Background Technology

[0002] In the field of lawn maintenance, lawn deers are key equipment for removing thatch and improving lawn aeration. Their performance and ease of use directly affect maintenance efficiency and lawn quality. Currently, lawn deers on the market are mainly divided into two categories: fuel-powered and electric. While fuel-powered lawn deers have stronger power, they suffer from problems such as high noise levels, serious exhaust pollution, bulky bodies, and complex operation. At the same time, their fuel consumption and subsequent maintenance costs are high, making it difficult to meet the needs of green, environmentally friendly, and low-cost maintenance.

[0003] While existing electric hay combers have improved in terms of environmental friendliness and noise control, they still suffer from several technical defects: First, the machine's structural design is unreasonable, often employing a horizontal or asymmetrical structure, leading to an unbalanced center of gravity. This results in tilting and swaying during operation, poor operational stability, and increased labor intensity for operators. Second, the power system has low integration, with motors and transmission components often being separately installed, lacking effective shock absorption and protection structures. This not only causes significant vibration during operation but also makes them prone to malfunctions due to dust and hay debris intrusion. Furthermore, the motor power is mostly concentrated in the 1000W-1500W range, which is insufficient when dealing with thick layers of dry hay, resulting in poor hay combing performance. Third, the control components have design flaws. Handles are often fixed or require tools to fold, making storage and carrying inconvenient. Some handle connections lack limiting anti-slip blocks, which can loosen and slip after prolonged use, affecting operational safety. Fourth, the safety control mechanism is inadequate. Most electric hay combers only have a single switch, posing a high risk of accidental activation and making it difficult to ensure the personal safety of operators. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric grass comb that is reasonably structured, stable in operation, energy-saving and environmentally friendly, safe and efficient, and easy to store and maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric brush comber, comprising a main body, wherein the overall structure of the main body is composed of a front working area, a middle power area, and a rear control area, which are fixedly spliced ​​together by high-strength connectors. The middle power area includes a sealed cavity disposed within the main body, a high-performance motor fixed to the motor platform within the cavity by a shock-absorbing bracket, and an output component. The rear control area includes a folding handle detachably connected to the middle power area. The folding handle consists of a gripping part, a connecting middle part, and a connecting end part. Limiting grooves are provided at the connection points between the gripping part and the connecting middle part, and at the connection points between the connecting middle part and the connecting end part, to ensure that slippage between components is prevented after the connection points of the folding handle are tightened by quick-release bolts.

[0006] The present invention is further configured such that: the front working area includes an open mounting groove located at the front end of the main body of the machine and a grass comb adapted to the mounting groove, wherein the grass comb can be grass comb teeth or grass combing plate.

[0007] The present invention is further configured such that: the output component includes a gear set that is driven to the output shaft of the motor, a drive shaft that is driven to the comb, and anti-slip wheels set at the four corners.

[0008] The present invention is further configured such that: the main body of the machine body is also provided with a dual control switch, the dual control switch including a main switch provided in the grip for hand gripping and an auxiliary switch provided on one side of the grip. The main switch is adapted to the shape and structure of the grip for hand gripping. When the auxiliary switch is activated, the machine operates normally when the hand grips the grip and the main switch is brought close to the grip.

[0009] The present invention is further configured such that: the rear end of the main body is provided with a collection box that is connected to the front working area, and the collection box is provided with a handle for easy holding.

[0010] The present invention is further configured such that: the motor power is 1600W to 2200W, and an adjustment switch for controlling the output power of the motor is provided on the upper part of the main body.

[0011] The present invention is further configured such that after the rear control area and the middle power area are installed, the folding handle and the middle power area are fixed within the working angle range of 150°-170° to prevent the control area from shaking during operation.

[0012] The beneficial effects of this utility model are:

[0013] 1. In terms of overall structure, the main body of the machine adopts a method of fixing and splicing the front working area, the middle power area, and the rear control area through high-strength connectors, which greatly improves the convenience of production and maintenance. The sealed cavity of the middle power area provides a stable and safe operating environment for key components such as motors. It can prevent dust, weeds, debris, and other foreign objects from entering the cavity, reducing wear on the motor and output components and extending the service life of the equipment. At the same time, the application of shock-absorbing brackets can effectively reduce the transmission of vibration generated by the motor during operation to other parts of the machine body, reduce the noise of the equipment during operation, improve the comfort of operation, and reduce the damage to the equipment structure caused by vibration. The detachable connection of the folding handle in the rear control area allows the handle to be easily folded and stored when not in use, facilitating storage and transportation and reducing the space occupied by the equipment. The limiting groove and quick-release bolt on the folding handle not only ensures the stability of the handle during use and prevents slippage between parts, ensuring operational safety, but also makes the folding and unfolding of the handle simple and quick, improving the flexibility of the equipment.

[0014] 2. The open mounting slot greatly facilitates the installation and removal of the grass comb. In practical use, when the grass comb wears out or is damaged due to prolonged operation, users can quickly and easily remove it from the mounting slot for replacement, without complicated tools or procedures, greatly saving maintenance time and effort. Moreover, this design makes grass comb replacement more flexible; users can choose the appropriate grass comb, such as comb teeth or comb plates, according to different lawn conditions and operational needs. Comb teeth are suitable for sparse, soft lawns, penetrating deep into the grass layer to effectively comb weeds and dead grass; comb plates are more suitable for denser, thicker lawns, enabling large-area grass combing operations and improving work efficiency. The gear set is connected to the motor output shaft, allowing for reasonable adjustment of the motor speed and torque according to actual operational needs. Through the speed-changing action of the gear set, the drive shaft can obtain the appropriate speed and torque, thereby driving the grass comb to perform grass combing operations in the best working condition.

[0015] 3. The main switch is located at the grip area, conforming to the shape and structure of this part. This ergonomic design allows users to access the main switch naturally and comfortably during operation. The auxiliary switch is located on one side of the grip area. The machine can only operate normally after the auxiliary switch is activated and the main switch is closed by gripping the grip area. This dual-control mechanism effectively prevents accidental machine start-up due to accidental activation of the main switch. Especially during equipment handling, storage, or debugging, it significantly reduces safety risks and protects the personal safety of operators. The collection box at the rear of the machine body is connected to the front working area, providing great convenience for hay combing operations. During hay combing, the combed weeds, dry grass, and other debris can directly enter the collection box through the connecting channel, preventing these debris from scattering randomly and maintaining a clean working environment. The handle on the collection box makes it easy for users to operate. When the debris in the collection box reaches a certain amount, users can easily grasp the handle to take out the collection box, empty the debris, and then reinstall it. The whole cleaning process is simple and quick, reducing the workload of manual weeding and improving the efficiency of weeding operations.

[0016] 4. The motor, with a power output between 1600W and 2200W, provides ample and flexible power to the hay comber, enabling it to powerfully complete hay combing operations and improve work efficiency. An adjustment switch on the top of the machine body allows users to easily adjust the motor power according to actual needs, achieving multi-purpose functionality and enhancing the equipment's adaptability to different operating scenarios. After the rear control area and the central power area are installed, the folding handle and the central power area are fixed within a working angle range of 150°-170°. This allows the operator to naturally and comfortably grip the folding handle for operation, reducing arm and body fatigue. Simultaneously, this angle effectively prevents wobbling of the control area during operation, allowing the operator to more accurately control the hay comber's direction of travel and working position, improving the accuracy and quality of the work.

Detailed Implementation

[0021] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0022] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0024] Figures 1 to 3An electric hay comber is shown, comprising a main body (1). The main body (1) is constructed by connecting a front working area, a middle power area (3), and a rear control area (4) with high-strength connectors, which greatly improves the convenience of production and maintenance. The middle power area (3) includes a sealed cavity inside the main body (1), a high-performance motor fixed to the motor platform within the cavity by a shock-absorbing bracket, and output components. The sealed cavity of the middle power area (3) provides a stable and safe operating environment for key components such as the motor. It prevents dust, weed debris, and other impurities from entering the cavity, reducing wear on the motor and output components and extending the service life of the equipment. At the same time, the application of the shock-absorbing bracket can effectively reduce the transmission of vibration generated by the motor during operation to other parts of the machine body, reduce the noise during operation, improve the comfort of operation, and reduce the damage to the equipment structure caused by vibration. The rear control area (4) includes a folding handle (5) detachably connected to the central power area (3). When not in use, it can be easily folded and stored, facilitating storage and transportation and reducing the space occupied by the equipment. The folding handle (5) consists of a grip (6), a connecting middle part (7), and a connecting end (8). Limiting grooves (9) are provided at the connection points between the grip (6) and the connecting middle part (7) and between the connecting middle part (7) and the connecting end (8). This not only ensures the stability of the handle during use and prevents slippage between components, ensuring operational safety, but also makes the folding and unfolding of the handle simple and quick, improving the flexibility of the equipment.

[0025] The front working area includes an open mounting slot (10) located at the front of the main body (1) and a grass comb that is compatible with the mounting slot. The open mounting slot (10) provides great convenience for the installation and removal of the grass comb. In actual use, when the grass comb is worn or damaged due to long-term operation, the user can quickly and easily remove it from the mounting slot for replacement without complicated tools and operating procedures, which greatly saves maintenance time and effort. Moreover, this design makes the replacement of the grass comb more flexible. Users can choose the appropriate grass comb, such as grass comb teeth (16) or grass combing board (11), according to different lawn conditions and operation needs. Grass comb teeth (16) are suitable for sparse and soft lawns and can penetrate deep into the grass layer to effectively comb weeds and dead grass; grass combing board (11) is more suitable for dealing with denser and thicker lawns and can carry out grass combing operations over a large area, improving work efficiency.

[0026] The output components include a gear set connected to the motor output shaft, a drive shaft connected to the grass comb, and anti-slip wheels (17) at the four corners. These components allow for reasonable adjustment of the motor's speed and torque according to actual operational needs. Through the gear set's speed-changing action, the drive shaft can obtain suitable speed and torque, thereby driving the grass comb to perform grass combing operations in optimal working condition. Under different lawn surface conditions, the anti-slip wheels (17) provide sufficient friction to prevent the grass comb from slipping or slipping during operation.

[0027] The main body (1) is also equipped with a dual-control switch, which includes a main switch (12) located on the grip (6) for handshake and an auxiliary switch (13) located on one side of the grip (6). The main switch (12) is adapted to the shape and structure of the grip (6) for handshake. This design conforms to the principles of ergonomics, allowing the user to naturally and comfortably touch the main switch (12) during operation. The auxiliary switch (13) is located on one side of the grip (6). The machine can only operate normally after the auxiliary switch is activated and the user holds the grip (6) to close the main switch (12). This dual-control mechanism effectively avoids the accidental start-up of the machine due to accidental activation of the main switch (12). Especially during the handling, storage, or debugging of the equipment, it can significantly reduce safety risks and protect the personal safety of operators.

[0028] The rear end of the main body (1) is also equipped with a collection box (14) that is connected to the front working area, which greatly facilitates the grass combing operation. During the grass combing process, the weeds, dry grass and other debris that are combed can be directly put into the collection box (14) through the connecting channel, which avoids these debris from being scattered at will and keeps the working environment clean. The handle 18 set on the collection box (14) makes it convenient for users to operate the collection box (14). When the debris in the collection box (14) reaches a certain amount, the user can easily hold the handle 18 to take out the collection box (14), empty the debris and then reinstall it. The whole cleaning process is simple and quick, reducing the workload of manual weed cleaning and improving the efficiency of grass combing operation.

[0029] When the motor power is less than 1600W, it cannot provide sufficient force and speed for the combing machine to operate; when the motor power is greater than 2200W, although it may make the combing machine more powerful and the combing efficiency higher in the short term, the energy consumption is also very high, which greatly increases the cost of use; therefore, a motor with a power of 1600W to 2200W, which is within the appropriate power range, can provide sufficient and flexible power for the combing machine, and can also complete the combing operation powerfully, thus improving work efficiency. In addition, the main body (1) is equipped with an adjustment switch (15) for controlling the output power of the motor, which allows the user to easily adjust the motor power according to the actual situation, realizing multiple uses of one machine and enhancing the adaptability of the equipment to different operating scenarios.

[0030] After the rear control area (4) and the middle power area (3) are installed, the folding handle (5) and the middle power area (3) are fixed within the working angle range of 150°-170°. The operator can hold the folding handle (5) naturally and comfortably to operate, reducing the fatigue of the arm and body. At the same time, this angle effectively avoids the shaking of the control area during operation, allowing the operator to more accurately control the direction of travel and working position of the comber, improving the accuracy and quality of the operation. When the angle is less than 150°, from an ergonomic point of view, the operator's hands and arms need to hold the handle in an unnatural posture when using the comber. After a long period of operation, the operator is prone to fatigue and soreness, and may even cause occupational diseases such as muscle strain, reducing the operator's work comfort and work efficiency. When the angle is greater than 170°, the excessive angle will change the center of gravity of the comber, causing the equipment to shake and become unstable during operation.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
