Description

Technical Field

[0001] This utility model relates to the field of garden management equipment, and in particular to a remote-controlled multi-functional garden management machine. Background Technology

[0002] In recent years, with the advancement of technology, the mechanization and automation of agricultural farming have been greatly improved. Garden tillers are common agricultural machinery. Due to the diversity of agricultural farming, and to meet production needs, multifunctional garden tillers have emerged. To adapt to automatic shuttle operations in fields, existing technology provides a remote-controlled garden tiller that eliminates the need for operators to accompany the equipment through the fields, thus improving efficiency and reducing labor intensity. Currently, garden tillers typically have only one reducer for driving the working device. This reducer is directly connected to the engine and then to the working device via a belt. This type of garden tiller has several drawbacks: 1. The engine speed is approximately 3000-3600 r / min. A typical reducer can reduce the speed to about 1700 r / min, but the working device requires a speed of only 200-300 r / min. Therefore, if only one reducer is used, the internal gears need to be redesigned, or additional gear stages need to be added to increase the reduction ratio, resulting in a larger reducer size and making it difficult to install on the garden tiller chassis. 2. Due to the high wear and short lifespan of the belt, regular maintenance and replacement are required, and adjusting the belt tension is cumbersome. Furthermore, the power transmission is a soft transmission, using a flexible belt tensioned on pulleys. While this offers advantages such as shock and vibration mitigation and noise reduction, it also suffers from short lifespan, high additional power consumption, susceptibility to environmental influences, and unstable power transmission. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a remote-controlled multi-functional garden management machine that is easy to deploy, has stable power transmission, and features multi-stage deceleration.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a remote-controlled multi-functional garden tiller, including a tracked chassis, on which an engine and a primary reduction gearbox are mounted. The output end of the engine is connected to the input end of the primary reduction gearbox via a main drive shaft. The primary reduction gearbox is located at the rear end of the tracked chassis, and its output end extends rearward. A secondary reduction gearbox is hinged to the rear of the primary reduction gearbox or the tracked chassis. The input end of the secondary reduction gearbox faces forward and is connected to the output end of the primary reduction gearbox via a universal drive shaft. A terminal working shaft for mounting terminal working components is rotatably mounted on the output end of the secondary reduction gearbox, which faces rearward. Both ends of the terminal working shaft extend beyond the left and right sides of the secondary reduction gearbox. A hydraulic lifting device is also provided between the secondary reduction gearbox and the primary reduction gearbox or the tracked chassis.

[0005] As a preferred technical solution, the tracked chassis includes a base and tracks installed on both sides of the base. Two travel motors are installed on the base, and the output shafts of the two travel motors are connected to the drive gears of the tracks.

[0006] As a preferred technical solution, the secondary reduction gearbox includes an integrally formed secondary reduction gearbox and a strip-shaped working box. The input end of the secondary reduction gearbox is connected to the primary reduction gearbox via the universal drive shaft, and the terminal working shaft is located at the lower rear end of the strip-shaped working box and is connected to the output end of the secondary reduction gearbox.

[0007] As a preferred technical solution, the secondary reduction gearbox is equipped with a reversing rod to control the forward or reverse rotation of the terminal working shaft.

[0008] As a preferred technical solution, the terminal working axis is a polygonal axis, and the polygonal axis is also provided with mounting holes.

[0009] As a preferred technical solution, the engine is located at the front end of the tracked chassis.

[0010] As a preferred technical solution, there is an unused space on both sides of the main drive shaft between the engine and the first-stage reduction gearbox.

[0011] As a preferred technical solution, the hydraulic lifting device is a hydraulic cylinder, one end of which is connected to the tracked chassis or the first-stage reduction gearbox, and the other end of which is connected to the second-stage reduction gearbox.

[0012] As a preferred technical solution, a hinge seat one is fixed on the first-stage reduction gearbox, and a hinge seat two is fixed on the second-stage reduction gearbox. The hinge seat one and the hinge seat two are rotatably connected, and the input end of the second-stage reduction gearbox passes through the hinge seat two and is connected to the output end of the first-stage reduction gearbox by the universal drive shaft.

[0013] As a preferred technical solution, the tracked chassis is also equipped with a wireless remote controller, a generator, and a battery pack. The wireless remote controller is wirelessly connected to the remote controller and is also connected to the two walking motors, the hydraulic lifting device, and the generator.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: In this utility model, the power transmission path of the terminal working component is: engine → main drive shaft → first-stage reduction gearbox → universal drive shaft → second-stage reduction working gearbox → terminal working shaft → terminal working component; the power transmission adopts rigid transmission, which is more stable and has a longer service life compared with the soft transmission in the prior art; this power transmission arrangement has two reduction gearboxes, and the two reduction gearboxes transmit power through a universal drive shaft. The two reduction gearboxes cooperate to reduce the engine speed to a speed that matches the terminal working component, and can reduce the size of the first-stage reduction gearbox, making it easier to arrange it reasonably on the tracked chassis. Meanwhile, the secondary reduction gearbox is not located on the tracked chassis, thus avoiding the difficulty of layout on the tracked chassis. In addition, to meet the layout requirements, the primary reduction gearbox needs to be located at the rear of the tracked chassis. However, in the prior art, the engine is generally directly connected to the primary reduction gearbox as a whole. Placing it at the rear of the tracked chassis not only shifts the overall center of gravity of the tracked chassis rearward, causing the whole machine to be unstable and tilting significantly during operation, reducing the working effect, but also affects the reasonable layout of other structures. Therefore, this application uses the main drive shaft to connect the primary reduction gearbox and the engine. The engine is no longer directly connected to the primary reduction gearbox, and the position of the engine can be replanned and arranged to adapt to the position of other structures.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figure 1 and Figure 2 As shown, the remote-controlled multi-functional garden management machine includes a tracked chassis. The tracked chassis includes a base 1 and tracks 2 installed on both sides of the base 1. Two walking motors 3 and drive reduction gearboxes 4 connected to the walking motors 3 are installed on the base 1. The output ends of the two drive reduction gearboxes 4 are connected to the drive gears 5 of the tracks 2. The drive gears 5 serve as the driving components of the tracks 2 and are existing technologies, which will not be described in detail here.

[0022] The tracked chassis is also equipped with a power transmission system that provides power to the terminal working components. This system includes a generator 6, an engine 7, and a primary reduction gearbox 8 mounted on the tracked chassis. The output end of the engine 7 is connected to the input end of the primary reduction gearbox 8 via a main drive shaft 9. The main drive shaft 9 is connected to the input end of the primary reduction gearbox 8 via a power output shaft sleeve. The primary reduction gearbox 8 is located at the rear end of the tracked chassis, with its output end extending rearward. A secondary reduction gearbox is hinged to the rear of the primary reduction gearbox 8 or the tracked chassis. The secondary reduction gearbox 10 has its input end facing forward and connected to the output end of the primary reduction gearbox 8 via a universal drive shaft 11. The output end of the secondary reduction gearbox 10 has a rotatably mounted terminal working shaft 12 for mounting terminal working components, with both ends of the terminal working shaft 12 extending beyond the left and right sides of the secondary reduction gearbox 10. A hydraulic lifting device is also provided between the secondary reduction gearbox 10 and the primary reduction gearbox 8 or the tracked chassis. The hydraulic lifting device is used to drive the secondary reduction gearbox 10 to rotate, rise, and fall.

[0023] The terminal working shaft 12 serves as the mounting carrier for the terminal working components. These components can be any one of the following: rotary tillage assembly 18, weeding assembly, ditching assembly, or fertilizer spreading assembly. They can be mounted on the garden tiller via the terminal working shaft 12, achieving multi-functionality. This allows the garden tiller to perform rotary tillage, weeding, ditching, and fertilizer spreading functions, thus realizing its versatility. (See also...) Figure 3 The diagram shows the rotary tillage assembly 18 installed on the terminal working shaft 12. In this embodiment, combined with... Figures 1 to 3 The engine 7 is located in front of the garden tiller, and the secondary reduction gearbox 10 is located behind the garden tiller. Of course, the front and rear positions can be changed according to the different terminal working components installed at the rear.

[0024] In this invention, the walking power comes from the walking motor 3, and the power of the terminal working component comes from the engine 7. The two power sources are independent of each other and do not affect each other. This not only facilitates the internal structure layout but also makes it easy to control them separately with a remote control. When it is necessary to adjust the walking speed, the speed of the drive reduction gearbox 4 of the walking motor 3 can be directly adjusted. When it is necessary to adjust the steering of the terminal working component, the gear of the secondary reduction gearbox 10 can be directly adjusted.

[0025] In this invention, the power transmission path of the terminal working component is as follows: engine 7 → main drive shaft 9 → first-stage reduction gearbox 8 → universal drive shaft 11 → second-stage reduction gearbox 10 → terminal working shaft 12 → terminal working component. The power transmission uses rigid transmission, which is more stable and has a longer service life compared to the soft transmission in existing technologies. This power transmission arrangement has two reduction gearboxes, which transmit power between each other via the universal drive shaft 11. The two reduction gearboxes work together to reduce the engine speed of 7 to a speed suitable for the terminal working component, and also reduce the size of the first-stage reduction gearbox 8, facilitating its reasonable arrangement on the tracked chassis. Simultaneously, the second-stage reduction gearbox 10 is not located on the tracked chassis, thus avoiding additional difficulties in its arrangement. Furthermore, to meet the arrangement requirements, the first-stage reduction gearbox 8 needs to be located at the rear end of the tracked chassis, whereas in existing technologies, the engine 7 and the first-stage reduction gearbox are generally located at the rear end of the tracked chassis. The direct, integrated connection of the primary gearbox 8 to the engine 7, placed at the rear of the tracked chassis, not only shifts the overall center of gravity of the tracked chassis rearward, causing instability and noticeable nose-lifting during operation, thus reducing operational efficiency, but also affects the rational arrangement of other structures. Therefore, this application uses a main drive shaft 9 to connect the primary gearbox 8 and the engine 7, eliminating the integrated connection between the engine 7 and the primary gearbox 8. The position of the engine 7 can be redesigned to accommodate the positions of other structures. The engine 7 can be placed at the front of the tracked chassis, with the engine 7 and the primary gearbox 8 located at opposite ends of the tracked chassis, balancing the center of gravity of the tracked chassis and ensuring the overall stability of the garden tiller. Furthermore, there is unused space on both sides of the main drive shaft 9 between the engine 7 and the primary gearbox 8, which can be used to place the drive motor and drive gearbox 4, achieving a rational arrangement.

[0026] The secondary reduction gearbox 10 includes an integrally formed secondary reduction gearbox and a strip-shaped work box. The input end of the secondary reduction gearbox is connected to the primary reduction gearbox 8 via the universal joint drive shaft 11. The terminal working shaft 12 is located at the lower rear end of the strip-shaped work box and is connected to the output end of the secondary reduction gearbox. The secondary reduction gearbox is equipped with a reversing rod 13 to control the forward or reverse rotation of the terminal working shaft 12, which is used to adapt to the usage requirements of different working devices. The secondary reduction gearbox is a gear reducer, used to achieve deceleration and reversal, which is existing technology and will not be described in detail here. The terminal working shaft 12 and the output end of the secondary reduction gearbox can be driven by gears or chains, mainly to make the strip-shaped work box form a forward-extending flat structure for mounting the terminal working parts.

[0027] The terminal working axis 12 is a polygonal axis, and the polygonal axis is also provided with mounting holes to facilitate the installation of the terminal working components.

[0028] The hydraulic lifting device is a hydraulic cylinder 14. One end of the hydraulic cylinder 14 is connected to the tracked chassis or the first-stage reduction gearbox 8 via a hinge seat, and the other end of the hydraulic cylinder 14 is connected to the housing of the second-stage reduction gearbox via a hinge seat. The extension and retraction of the hydraulic cylinder 14 can realize the lowering and raising of the terminal working component.

[0029] A hinge seat 1 is fixed on the first-stage reduction gearbox 8, and a hinge seat 2 is fixed on the housing of the second-stage reduction gearbox. The hinge seat 1 and the hinge seat 2 are rotatably connected. The input end of the second-stage reduction gearbox passes through the hinge seat 2 and is connected to the first-stage reduction gearbox 8 by the universal drive shaft 11.

[0030] The tracked chassis is also equipped with a wireless remote controller 15, which is wirelessly connected to a remote controller. The wireless remote controller 15 is also connected to the two walking motors 3, the hydraulic lifting device, and the generator 6, and can directly control the walking speed, terminal lifting, and terminal speed through the remote controller.

[0031] The tracked chassis is also equipped with a battery pack, including a starter battery box 16 for providing power to the generator 6 and a drive battery box 17 for providing power to the walking motor 3.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
