Description

Technical Field

[0001] This application relates to the field of shovel and rake equipment technology, specifically to a shovel and rake machine. Background Technology

[0002] Loosening and rakeing machines are widely used in landscaping, agricultural planting and other fields. Their core function is to loosen and level the surface soil, while removing or collecting solid debris such as grass roots, thereby creating a flat and loose soil environment for plant growth or site maintenance.

[0003] The brush rollers of existing rakes are usually of a fixed length, which means that each model with a different working width needs to have its corresponding brush rollers manufactured separately, thus increasing production costs. At the same time, users need to purchase models with different widths to meet the actual needs of different operating scenarios, which reduces the flexibility of equipment use and increases the user's purchase and use costs.

[0004] Therefore, there is room for further improvement in the existing raking machine technology. Utility Model Content

[0005] In view of this, and in response to the technical problems of high production costs and poor equipment flexibility caused by the fixed length of the brush roller in the existing raking machine, this utility model provides a raking machine that sets the brush roller as at least two detachably connected roller units. By increasing or decreasing the number of roller units, the length of the brush roller can be flexibly adjusted, thereby adapting to various working widths, reducing production costs, and improving the flexibility and economy of equipment use.

[0006] This application provides a rake loosening machine, comprising: Organism; A brush roller is rotatably mounted on the machine body; it includes at least two roller units, which are arranged sequentially along the axial direction of the brush roller, and adjacent roller units are detachably connected. The working length of the brush roller can be adjusted by increasing or decreasing the number of roller units.

[0007] Compared with the prior art, the rake loosening machine of this application has a brush roller comprising at least two roller units arranged sequentially along the axial direction and detachably connected. The working length of the brush roller can be adjusted by increasing or decreasing the number of roller units. Compared with the rake loosening machine with a fixed working width in the prior art, the rake loosening machine of this application has a larger working range. When it is necessary to deal with different working environments, such as narrow or wide ones, it is only necessary to reduce or increase the number of roller units accordingly, without replacing the whole machine or major components. This achieves multi-purpose functionality, thereby significantly improving the adaptability of the equipment to different working scenarios and reducing the user's purchase and maintenance costs.

[0008] Preferred options also include: The drive mechanism is located on the machine body; A transmission mechanism, the input end of which is connected to the output end of a drive mechanism; The speed reduction mechanism has its input end connected to the output end of the transmission mechanism, and its output end connected to the input end of the brush roller.

[0009] In this embodiment, the power output of the drive mechanism is sent to the transmission mechanism, which further transmits the power to the reduction mechanism. Finally, the reduction mechanism can convert the high-speed power generated by the drive mechanism into a low-speed power with greater torque suitable for the operation of the brush roller, thereby ensuring that the brush roller has sufficient force and stable speed during operation, effectively improving the effect of debris collection and turf combing.

[0010] Preferably, the transmission mechanism includes: The input pulley is connected to the output shaft of the drive mechanism; intermediate pulley; The output pulley is connected to the input shaft of the reduction mechanism; The first transmission belt is wrapped around the input pulley and the intermediate pulley; The second drive belt wraps around the intermediate pulley and the output pulley.

[0011] In this embodiment, the multi-stage transmission of the transmission mechanism achieves effective speed reduction and torque increase, reduces reliance on a single speed reduction mechanism, and makes power transmission more stable and reliable. At the same time, the first and second transmission belts can also reduce noise and vibration during machine operation.

[0012] Preferred options also include: A waste collection bin is mounted on the machine body; the opening of the waste collection bin faces the brush roller. The garbage collection bin includes a bin body and a support frame. The support frame is connected to the bin body and provides structural support for the bin body. The support frame is detachably connected to the bin body. The support frame includes multiple rods, which are detachably connected; A baffle is movably connected to the opening of the trash can; The baffle combing rib is located on the edge of the baffle near the brush roller and extends from the baffle toward the brush roller.

[0013] In this embodiment, the waste collection bin can collect debris swept out by the brush roller, and the baffle can efficiently receive the debris swept out by the brush roller. The comb ribs on the baffle can effectively remove fibrous debris wrapped around the brush, preventing the roller from clogging. The movable connection of the baffle facilitates the dumping of waste and the storage of the whole machine. In addition, the support frame of the waste collection bin is detachably connected to the bin body, and the support frame itself is also composed of multiple detachably connected rods, so that the entire waste collection bin can be quickly disassembled into small parts such as the bin body and support frame rods, which greatly facilitates transportation, storage and daily storage, saves space, and also facilitates partial replacement or repair, reducing maintenance costs.

[0014] Preferably, the baffle is a one-piece molded folded plate, the plate surface of which includes the following sequentially connected components: The receiving section, whose plate surface forms an angle α with the horizontal direction satisfying 30°≤α≤60°, is used to receive debris swept out from the brush roller; The blocking section has an angle β between its surface and the horizontal direction satisfying 85°≤β≤90°, and is used to prevent debris from falling out of the garbage collection bin.

[0015] In this embodiment, the receiving section of the baffle is at an angle of 30° to 60° to the horizontal direction, which can effectively receive the debris swept out by the brush roller and guide it smoothly into the garbage collection bin; the blocking section is at an angle of 85° to 90° to the horizontal direction, which can reliably prevent the collected debris from falling out of the garbage collection bin. This design can significantly improve the leak-proof effect and reliability of the collection bin while ensuring the smooth collection of debris.

[0016] Preferred options also include: A quick-release mechanism is provided at at least one end of the two ends of the brush roller, the quick-release mechanism being used to quickly separate or connect the brush roller to the machine body.

[0017] In this embodiment, the quick-release mechanism can quickly remove and install the brush roller, making it easy to replace the brush roller and improving the convenience of equipment transportation and storage.

[0018] Preferably, the quick-release mechanism includes: A fixed mounting bracket is fixedly installed on the machine body; The movable pressure cap has one end rotatably connected to the fixed card seat; The guide groove includes a locking groove and an unlocking groove; wherein the locking groove is formed on the fixed card seat, and the unlocking groove is formed at the free end of the movable pressure cover; A sliding pin is slidably disposed in the guide groove; When the sliding pin slides into the locking groove along the guide groove, the movable cover engages with the fixed bracket to lock the end of the brush roller. When the sliding pin slides into the unlocking slot along the guide groove, the movable cover can be lifted around its rotating end to allow the end of the brush roller to enter or exit the fixed bracket.

[0019] In this embodiment, the quick-release mechanism can be locked and opened by pushing the sliding pin, which simplifies the disassembly and assembly process and improves maintenance efficiency.

[0020] Preferred options also include: A front baffle is located on the front side of the brush roller along the machine's travel direction; The front baffle comb rib is located on the edge of the front baffle near the brush roller and extends from the front baffle toward the brush roller.

[0021] In this embodiment, by providing a front baffle with front combing ribs on the front side of the brush roller in the direction of travel, the turf can be pre-combed during operation and debris can be effectively blocked from splashing in front, thereby improving the subsequent sweeping and combing effect and the cleanliness of the operation.

[0022] Preferred options also include: The walking wheel assembly is located on the machine body; A height adjustment mechanism, connected to the wheel assembly and / or the body, is used to adjust the height of the wheel assembly relative to the body.

[0023] In this embodiment, the height adjustment mechanism can conveniently adjust the height of the walking wheels relative to the machine body, thereby flexibly controlling the working depth of the brush roller, enabling the equipment to adapt to different ground thicknesses and effectively improving the terrain adaptability of the equipment.

[0024] Preferably, a pair of vertical mounting slots are symmetrically provided on both sides of the front end of the body; The height adjustment mechanism includes: The lifting rod has its two ends movably mounted in a pair of mounting slots; The operating handle is hinged to the machine body; The transmission connecting rod is L-shaped, with one end hinged to the operating handle and the other end hinged to the lifting rod; A mounting shaft is provided at the bend of the transmission link, and the wheel axle of the walking wheel assembly is mounted on the mounting shaft.

[0025] In this embodiment, turning the operating handle will drive the lifting rod to rotate through the lever principle. The lifting rod will lift the machine body upward, thereby changing the relative height of the machine body with respect to the walking wheel assembly. This structure is compact and easy to operate.

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0029] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0030] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 9 illustrate.

[0032] This application provides a rake loosening machine, such as Figures 1 to 9 As shown, the raking machine mainly includes a body 100, a brush roller 200, a drive mechanism 300, a transmission mechanism 400, a reduction mechanism 500, a garbage collection bin 600, a baffle 700, a quick-release mechanism 800, a front baffle 900, a walking wheel assembly 1000, and a height adjustment mechanism 1100.

[0033] The machine body 100 forms the basic frame of the entire device, and the brush rollers 200 are rotatably mounted below the machine body 100 via shafts at both ends. Figure 2 , Figure 3 As shown, the brush roller 200 is not a single piece, but rather composed of multiple independent roller units connected axially in a detachable manner using bolts or other means. When the working area is narrow, the operator can remove some roller units to reduce the working width of the brush roller 200, thus adapting it to the confined space. Conversely, when the working area is wide, additional roller units can be added to increase the working width, adapting it to a wider area. This design allows operators to flexibly adjust the working width of the rake without purchasing models with different working widths, thus increasing the applicability of individual machines and reducing equipment purchase costs for users. Furthermore, when local brushes wear out, only the damaged unit needs to be replaced, eliminating the need to replace the entire roller, significantly reducing maintenance costs.

[0034] Furthermore, the structure of the transmission mechanism is described in detail, and the power transmission path is as follows: Figures 3 to 5 As shown, the drive mechanism 300 is fixedly installed inside the body 100. The drive mechanism 300 can be a gasoline engine or an electric motor. Its output power is first transmitted to the transmission mechanism 400. Specifically, the transmission mechanism 400 includes an input pulley 401 connected to the output shaft of the drive mechanism 300, an intermediate pulley 402, an output pulley 403 connected to the input shaft of the reduction mechanism 500, a first transmission belt 404 wrapped around the input pulley 401 and the intermediate pulley 402, and a second transmission belt 405 wrapped around the intermediate pulley 402 and the output pulley 403. The power here enters the reduction mechanism 500 after passing through the transmission mechanism 400. The reduction mechanism 500 reduces the speed to the appropriate working speed required by the brush roller 200 and finally drives it to rotate. The reduction mechanism 500 can be a planetary gear reducer.

[0035] To further enhance the practicality of the slack harrow, it is also equipped with a waste collection function, which can effectively collect weeds, debris, and other waste from the soil surface. Figure 6 As shown, the raking machine is equipped with a garbage collection bin 600, which is installed on the machine body 100 and located above and behind the brush roller 200. Its opening faces the brush roller 200 and is used to collect debris. The garbage collection bin 600 includes a rigid box body and a support frame 601. The box body is the main housing part of the garbage collection bin 600, that is, the outer shell structure of the garbage collection bin 600. The support frame 601 is connected to the box body and provides structural support for the box body. The support frame 601 and the box body are detachably connected. At the same time, the support frame 601 itself is also composed of multiple rods connected by detachable means (such as bolts and pins). This design allows the entire garbage collection bin to be quickly disassembled, which greatly facilitates transportation and storage. The waste collection bin 600 is also equipped with a baffle 700. The baffle 700 is movably connected to the lower edge of the opening of the waste collection bin 600 via hinges or pivots. The edge of the baffle 700 near the brush roller 200 has baffle comb ribs 701 extending towards the brush roller 200. Their function is to effectively scrape off debris entangled or attached to the brush when the brush roller 200 rotates. Furthermore, the baffle 700 is an integrally formed folded plate structure. Its plate surface includes a receiving section 702 and a blocking section 703 connected in sequence. The angle α between the plate surface of the receiving section 702 and the horizontal direction can be selected between 30° and 60°. Its tilt angle is conducive to smoothly receiving debris swept out from the brush roller 200. The angle β between the plate surface of the blocking section 703 and the horizontal direction can be selected between 85° and 90°. Its angle can effectively prevent debris that has entered the waste collection bin 600 from falling out.

[0036] To further facilitate the replacement of the brush rollers, the rake is also equipped with a quick-release mechanism 800, such as... Figure 7 , Figure 8 As shown, the quick-release mechanism 800 is disposed at at least one end of the brush roller 200, and includes a fixed bracket 801 and a movable pressure cover 802. The fixed bracket 801 is fixedly installed on the machine body 100, and one end of the movable pressure cover 802 is rotatably connected to the fixed bracket 801. Specifically, a locking groove is provided on the fixed bracket 801, and an unlocking groove is provided on the free end of the movable pressure cover 802. The locking groove and the unlocking groove together form a continuous guide groove, and a sliding pin 803 is slidably disposed in this guide groove. When it is necessary to fix the brush roller 200, slide the sliding pin 803 into the locking groove on the fixed bracket 801 along the guide groove. At this time, the movable cover 802 and the fixed bracket 801 are tightly engaged, thereby firmly locking the shaft head at the end of the brush roller 200. When it is necessary to disassemble the brush roller 200 for maintenance or replacement, slide the sliding pin 803 into the unlocking groove on the movable cover 802, so that the movable cover 802 can be lifted around its hinge end, thereby allowing the end of the brush roller 200 to fall into or move out of the fixed bracket 801, realizing quick disassembly and assembly.

[0037] To further protect the rake, such as Figure 6 As shown, a front baffle 900 is provided on the front side of the brush roller 200 along the machine's traveling direction. The front baffle 901 is provided on the front baffle 900 and extends to the edge of the brush roller 200. The front baffle comb 901 can pre-comb the turf when the machine moves forward and block larger debris in front of the working area of ​​the brush roller 200 to prevent it from splashing or getting stuck in the roller.

[0038] To further facilitate adaptation to different operational needs, a height adjustment mechanism 1100 is also provided, which can effectively adjust the height of the walking wheel assembly 1000 relative to the machine body 100, such as... Figure 9As shown, the walking wheel assembly 1000 is connected to the body 100 via a height adjustment mechanism 1100. A pair of vertical mounting slots 101 are symmetrically provided on both sides of the front end of the body 100. The height adjustment mechanism 1100 includes a lifting rod 1101, an operating handle 1102, and an L-shaped transmission link 1103. Both ends of the lifting rod 1101 are movably fitted into the pair of mounting slots 101. The middle part of the operating handle 1102 is hinged to the body 100. One end of the transmission link 1103 is hinged to the lower end of the operating handle 1102, and the other end is hinged to the middle part of the lifting rod 1101. A mounting shaft 11031 is provided at the bend of the transmission link 1103. The axle of component 1000 is mounted on this mounting shaft 11031. When the free end of the operating handle 1102 is pressed down, the operating handle 1102 will pull the transmission link 1103, which in turn pushes the lifting rod 1101 to move upward along the mounting groove 101, thereby lifting the front end of the machine body 100, increasing the height of the brush roller 200 off the ground and making the working depth shallower. Conversely, when the operating handle 1102 is lifted up, the lifting rod 1101 moves down, the front end of the machine body 100 descends, and the working depth of the brush roller 200 increases. Through this mechanism, the operator can easily adjust the working depth of the raking machine to adapt to different turf conditions and operational needs.

[0039] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0040] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
