Technical Field

[0001] This invention relates to the field of intelligent agricultural machinery and equipment technology, and in particular to a mowing mechanism capable of actively conveying materials and a mowing robot equipped with a material collection device. Background Technology

[0002] A lawnmower is a mechanical tool used to trim lawns and vegetation. Its core function is to maintain the neatness and appearance of the lawn or to prevent the grass from growing too tall. It is mainly divided into handheld, push-type, and ride-on types. Power sources include human power, internal combustion engines, and electric motors. It generally cuts tall grass through high-speed rotating blades or reciprocating toothed blades.

[0003] Using a single rotary blade (instead of a roller blade) in a lawnmower presents a trade-off between mowing efficiency and blade diameter. While using multiple rotary blades can improve mowing efficiency, it may result in missed mowing spots.

[0004] Existing lawn mowers still have shortcomings. The grass cut from tall grass is usually left directly on the site and requires manual or mechanical processing, resulting in low efficiency. Summary of the Invention

[0011] Preferably, the venting opening faces the discharge port or an adjacent venting cavity.

[0012] Preferably, the venting flare and the venting narrow opening work together to form a spiral upward flow field within the venting cavity that guides the forage to move toward the discharge port.

[0013] Preferably, the narrow opening of the drainage channel is stepped.

[0014] Another objective of this invention is to provide a mowing robot equipped with a grass collection device, for installing the above-described active grass-feeding mowing mechanism, comprising: a chassis, wherein the protective cover is installed at the bottom of the chassis via a lifting device; The forage recycling bin is connected to the front of the forage recycling bin via the material conveying channel, and the forage recycling bin is installed at the rear of the chassis.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1: Reference Figures 1-16 A mowing mechanism capable of actively conveying materials includes: a protective cover 1, wherein the protective cover 1 is provided with a discharge port 11; Cutting tool 2, at least one set of cutting tools 2 is rotatably connected inside the protective cover 1, which can cut tall grass into hay; The material conveying channel 12 is connected to the material outlet 11, and a conveying mechanism is connected inside the material conveying channel 12. When the cutter 2 rotates, it can generate a conveying airflow, which can transport the grass through the outlet 11 into the conveying channel 12.

[0022] At least one motor is installed inside the protective cover 1. The output shaft of the motor is connected to a set of cutters 2. After the tall grass is cut into grass by the rotation of the cutters 2, the grass is transported to the discharge port 11 and discharged through the conveying channel 12 by the conveying airflow generated by the rotation of the cutters 2. The grass can be automatically collected, avoiding repeated processing of the grass after the cutting is finished, which greatly improves the working efficiency of the device. In some embodiments that have adopted the negative pressure adsorption method to collect grass, the cutters 2 can enhance the adsorption airflow while performing the cutting action, thereby improving the conveying efficiency of grass.

[0023] It should be noted that the function of the motor is to provide driving force to the cutting tool 2. The number of motors and the number of cutting tools 2 are not completely one-to-one. The output end of one motor can also be connected to multiple sets of cutting tools through a gear transmission system, a belt and pulley transmission system, or a sprocket and chain system. This application does not impose any restrictions on this. The motor can be set inside the protective cover 1 or outside the protective cover 1. This application does not impose any restrictions on this.

[0024] Depending on the production cost and operating environment of the device, the material of the protective cover 1 can be stainless steel, aluminum alloy, composite material (such as glass fiber reinforced plastic or carbon fiber reinforced plastic), engineering plastic (such as polyamide or polycarbonate), or coated metal, etc., to meet the requirements of the protective cover 1 for weathering resistance, dust resistance, mud resistance, rust resistance, and impact resistance from gravel. The protective cover 1 can be processed by stamping, casting, forging, CNC machining, vacuum bag forming, electroplating, spraying, or injection molding, etc., and can be produced by manufacturers with different production equipment. This application does not limit the material and processing method of the protective cover 1.

[0025] Furthermore, the function of the conveying mechanism is to convey the forage formed after the tall grass is cut within the conveying channel 12 and to prevent the conveying channel 12 from becoming blocked. The conveying mechanism in this embodiment includes a conveying motor 121, a bevel gear 122, a second bevel gear 123, a conveying shaft 124, and a spiral blade 125. The conveying motor 121 is fixedly installed outside the conveying channel 12, and the output end of the conveying motor 121 extends into the conveying channel 12. The output end of the conveying motor 121 is connected to the bevel gear 122, which meshes with the second bevel gear 123. The second bevel gear 123 is connected to the conveying shaft 124, and the conveying shaft 124 is rotatably connected to the conveying channel 12. A spiral blade 125 is connected to the conveying shaft 124. In this embodiment, the conveying shaft 124 is rotatably connected to multiple support structures (some not shown), thereby constraining the conveying shaft 124 as a whole within the center position of the conveying channel 12. This confines the spiral blade 125 connected to the conveying shaft 124 within the conveying channel 12 and ensures its stability during operation. After the conveying motor 121 starts, it drives the bevel gear 122 to rotate through the output end. The bevel gear 122 meshes with the second bevel gear 123, driving the conveying shaft 124 to rotate, ultimately causing the spiral blade 125 to rotate. The rotating spiral blade 125 can push the grass upward, which can improve the conveying efficiency of the grass and prevent the grass from being blocked inside the conveying channel 12. In another embodiment of this application, such as Figure 12As shown, the output end of the conveyor motor 121 is connected to a bevel gear 122. A bevel gear four 127 is meshed with one side of the bevel gear 122, and a bevel gear three 126 is meshed with the other side. Since one side of the bevel gear four 127 meshes with the bevel gear 122, a conveyor shaft three 138 is connected to the shaft center on the other side. Similarly, since one side of the bevel gear three 126 meshes with the bevel gear 122, a conveyor shaft two 128 is connected to the shaft center on the other side. The bevel gears 122, three 126 (and conveyor shaft two 128), and four 127 (and conveyor shaft three 138) constitute a coaxial reversing mechanism. In this embodiment, the conveying mechanism is not horizontally positioned relative to the ground; the end closer to the sky and farther from the ground is the upper part, and the end closer to the ground and farther from the sky is the lower part. An upper helical blade 129 is provided on the second conveyor shaft 128 above the bevel gear 122, and a lower helical blade 130 is provided on the third conveyor shaft 138. The upper helical blade 129 and the lower helical blade 130 are arranged in opposite directions to ensure that the gas flowing inside the conveying channel 12 is uniformly from bottom to top when the coaxial reversing mechanism is working. The number of teeth of the third bevel gear 126 above the conveying motor 121 is greater than the number of teeth of the other bevel gear 127. Therefore, the rotation speed of the upper helical blade 129 is less than the rotation speed of the lower helical blade 130. Therefore, when conveying grass, the high-speed rotation of the lower helical blade 130 can be used to push the grass upward. The pitch of the upper helical blade 129 is gradually reduced (the pitch is larger relative to the bevel gear 122 and smaller relative to the bevel gear 122), which can compress the grass into a ball. While promoting the output of grass, it can also prevent the upper helical blade 129 and the conveying channel 12 from being blocked by grass. In another technical solution of this embodiment, in order to prevent the reduction of the conveying airflow from affecting the mowing efficiency, one or more air holes 131 need to be opened through the inner wall of the conveying channel 12. The air holes 131 are set near the bottom of the upper spiral blade 129 (that is, the end of the upper spiral blade 129 near the lower spiral blade 130). Its function is that when the grass at the upper spiral blade 129 is conveyed and compressed (the conveying airflow is blocked and the conveying efficiency is reduced), the grass at the lower spiral blade 130 can still be conveyed normally and can accumulate at the bottom of the upper spiral blade 129 to form an upward thrust, which can promote the grass at the upper spiral blade 129 to be pushed out. At the same time, the rotation of the upper spiral blade 129 can also scrape away the grass that may be blocked at the air holes 131, ensuring the communication between the air holes 131 and the inside of the grass recycling box 31.

[0026] In another embodiment of this application, the output end of the conveying motor 121 is connected to bevel gear 5 132, which meshes with bevel gear 6 133. Bevel gear 6 133 has a through-hole in its center, through which the conveyed material passes. Bevel gear 6 133 is coaxially rotatably connected to the inner wall of the conveying channel 12 via a support structure 2. Multiple spiral propulsion blades 134 are circumferentially arrayed on the bottom end face of bevel gear 6 133. The bottom ends of the spiral propulsion blades 134 are slidably connected to the bottom wall of the conveying channel 12, or can be connected to a rotating ring. The rotating ring is connected to the feed end at the bottom of the conveying channel 12, and the rotating ring rotates in conjunction with the bottom wall of the conveying channel 12. The spiral propeller 134 slides against the inner wall of the conveying channel 12. This arrangement prevents the forage from adhering to the inner wall of the conveying channel 12 when conveying forage with high moisture content, especially when the forage has a high moisture content. It also prevents the growth of microorganisms inside the conveying channel 12 after operation and prevents the metal parts inside the conveying channel 12 from rusting, thus avoiding a reduction in the service life of the conveying channel 12. It also prevents biological contamination inside the device. Based on existing technology, the rotating spiral propeller 134 can generate a conveying airflow parallel to the axis of the conveying channel 12 to convey the forage. In another embodiment of this application, a plurality of gradually changing spiral propellers 135 are circumferentially arrayed on the bottom end face of the bevel gear 133. The gradually changing spiral propellers 135 slide in contact with the inner wall of the conveying channel 12 to clean the grass on the conveying channel (scrape off the grass adhering to the inner wall of the conveying pipe). The connection between the bottom end of the gradually changing spiral propellers 135 and the conveying channel 12 is the same as that of the spiral propellers 134. When the gradually changing spiral propellers 135 rotate, they form an internal flow channel 136. In this embodiment, the internal flow channel 136 adopts a progressive design, that is, the top of the internal flow channel 136 is provided with a narrowing region 137. The narrowing region 137 can enhance the airflow of grass conveying by utilizing the Venturi effect. At the same time, by increasing the width of a portion of the propeller, the gradually changing spiral propellers 135 can also effectively enhance the airflow of the conveying material and improve the conveying efficiency when they rotate.

[0027] Example 2: Reference Figures 1-16 The rotating surface of the blade 2 is provided with a guide structure for generating and enhancing the material conveying airflow. When the blade 2 performs the grass cutting action, the guide structure can generate or enhance the material conveying airflow. The guide structure is a non-flat structure.

[0028] In this embodiment, as shown in Figure 6, the flow guiding structure is a flow guiding plate 21 with an upturned tail on the rotating surface of the cutter 2. When the cutter 2 rotates, the flow guiding plate 21 does work on the air, and a pressure difference is formed between its windward and leeward surfaces, which in turn promotes the directional flow of air to generate or enhance the material conveying airflow. After the material conveying airflow is generated, the grass is conveyed into the material conveying channel 12. The guide plate 21 is located on the back of the blade away from the cutting edge 22 in the tool 2. The advantage of this arrangement is that the tool 2 and the guide structure can be cast in one piece, or the guide structure can be manufactured by casting first and then stamping, so as to be suitable for processing plants with different production equipment and production conditions. Since the materials used to manufacture the cutting tool 2 may be different (e.g., carbon steel, stainless steel, alloy steel, etc.), and the hardness and machinability of different materials vary, the above measures can be used to set up a flow guiding structure to reduce the machining difficulty of the cutting tool 2. In another embodiment, the guide plate 21 is disposed on the top of the cutter 2 and is manufactured by welding or casting to suit manufacturers with different equipment and different production capacities. In another embodiment, based on the design of the non-flat flow guide structure, the tool 2 is set in a spiral shape from its shank to its tip, such as a fan blade structure, so that the tool 2 can be manufactured to be used in more processing equipment, increasing the convenience of manufacturing the tool 2 and the speed of equipment production. Specifically, based on the prior art, the tool 2 under this condition still has a straight cutting edge, and its spiral structure is set at its blade body.

[0029] Example 3: Reference Figures 1-16 The protective cover 1 is provided with multiple grass cutting chamber units 13. Each grass cutting chamber unit 13 contains a set of blades 2. Two adjacent grass cutting chamber units 13 are connected and are arranged facing the discharge port 11.

[0030] Multiple cutting chamber units 13 inside the protective cover 1 can be divided by plates. The two sides of the plates face a blade 2, and their ends are connected to the protective cover 1. The other end faces the flow direction of the material conveying airflow, so that two adjacent cutting chamber units 13 can be connected and are set towards the discharge port 11. The setting of the cutting chamber units 13 avoids interference between two adjacent blades 2 and the material conveying airflow, further improving the conveying efficiency of grass during conveying.

[0031] Example 4: Reference Figures 1-16 The spiral guide plate 15 and the blade 2 in each of the mowing chamber units 13 form a guide chamber 14, and a guide flare and a guide narrow flare are formed between the spiral guide plate 15 and the blade 2.

[0032] The venting opening faces the discharge port 11 or the adjacent venting cavity 14.

[0033] The rotating cutter 2, in conjunction with the venting and narrowing openings, forms a spiral upward airflow field within the venting cavity 14 that guides the forage towards the discharge port 11.

[0034] The top of the mowing chamber unit 13 is connected to the spiral guide plate 15. The plate, the protective cover 1 and the blade 2 constitute the guide chamber 14. The conveying airflow forms an upward airflow field in the guide chamber 14. The grass is conveyed from the narrow guide opening to the wide guide opening in the upward airflow field. After the grass is gathered by the two adjacent wide guide openings, it is input into the conveying channel 12.

[0035] Example 5: Reference Figures 1-16 The narrow opening of the drainage channel is stepped.

[0036] The stepped structure set at the narrow opening of the guide creates a blocking effect on the grass located in the area of ​​the discharge port 11, while enhancing the intensity of the conveying airflow, causing the grass to be discharged directly from the discharge port 11, and preventing the grass from flowing back into the guide cavity 14.

[0037] Example 6: Reference Figures 1-16 A mowing robot equipped with a grass collection device, used to install any of the active grass-feeding mowing mechanisms described in the above embodiments, including: a chassis 3, wherein the protective cover 1 is installed at the bottom of the chassis 3 via a lifting device; The forage recycling bin 31 is connected to the front of the forage recycling bin 31 via the material conveying channel 12, and the forage recycling bin 31 is installed at the rear of the chassis 3. Filter screen 32 is provided at the rear of the hay recycling bin 31; The top of each of the two sides of the hay recycling bin 31 is rotatably connected to a driving component 33; The bottom opening of the hay recycling bin 31 is hinged to the end of the tray 34, and the output end of a drive unit 33 is rotatably connected to each side of the tray 34. The bottom opening of the hay recycling bin 31 is sealed to the tray 34.

[0038] In one embodiment of a lawnmower robot equipped with a grass collection device provided in this application, the chassis 3 adopts the six-wheeled bionic chassis disclosed in application number CN202011155327.8 on October 26, 2020. Its bottom is used to install any one of the existing hydraulic lifting devices, pneumatic lifting devices, screw lifting devices, or rack and pinion lifting devices. The output end of the lifting device is connected to the protective cover 1 to adjust the distance between the blade 2 and the bottom surface. The adjustment stroke is between 25-125mm, so that the blade 2 will not come into contact with gravel or dirt mounds on the ground while fulfilling the weeding task, thus protecting the blade 2 and improving the practicality and safety of the device during use. Simultaneously, height adjustment allows for cutting tall grass of different heights, thereby improving the cutting efficiency of tall grass. Since a lifting device is installed inside the device, to prevent the protective cover 1 and the material conveying channel 12 from jamming after height adjustment, the discharge port 11 is slidably connected to the material conveying channel 12. Of course, in other embodiments, such as... Figure 8 As shown, the fodder recycling bin 31 is fixed to the protective cover 1, thus the protective cover 1 and the material conveying channel 12 are connected in a fixed manner.

[0039] The hay collection bin 31 is used to receive hay from the conveying channel 12. The purpose of the filter screen 32 is to release the airflow entering the hay collection bin 31 and intercept the hay to prevent the hay from damaging the surrounding area when mowing. After the lawn is mowed, the hay collection bin 31 is filled with hay. As the chassis 3 moves, the hay collection bin 31 is taken to the designated hay collection point. With the hinged engagement at the bottom opening of the hay collection bin 31 and the rotatable connection between the output end of the drive unit 33 and the side of the tray 34, the drive unit 33 starts its output end to drive the tray 34 to rotate downward around its end. The output end of the drive unit 33 and the tray 34 rotate relative to each other. After the bottom opening is opened, the hay in the hay collection bin 31 is discharged. Since the top of the drive unit 33 is rotatably connected to the side of the hay collection bin 31, the body of the drive unit 33 will rotate when the tray 34 is opened. After the discharge of hay is finished, the drive unit 33 is started again. The body of the drive unit 33 rotates in the opposite direction, and the tray 34 rotates upward around its end. After the output end of the drive unit 33 and the tray 34 rotate in opposite directions, the opening at the bottom of the hay recycling box 31 is sealed to prepare for the next operation. In one embodiment, the drive component 33 is a hydraulic cylinder that operates using hydraulic oil driven by a hydraulic pump. It has extremely strong thrust, which ensures that the pallet 34 can stably seal the bottom opening and prevent the leakage of straw during operation. At the same time, it has the advantages of smooth operation, strong impact resistance, long-term pressure holding and overload protection.

[0040] Example 7: Reference Figures 1-16 The drive components 33 on both sides of the hay recycling bin 31 are electric actuators. The working process of the actuators driving the tray 34 to open and close the bottom opening is the same as the working process of the hydraulic cylinder used in Embodiment 6. The electric actuators work through the motor equipment and have the characteristics of low delay, fast response speed, high movement accuracy, convenient installation and extremely high work efficiency.

[0041] In addition, in some other embodiments, the drive unit 33 may be a rotary drive such as a rotary cylinder that opens and closes the pallet 34 by rotation.

[0042] Example 8: Reference Figures 1-16 It also includes: a waterproof protective cover 35, two of which are respectively installed on one side of the hay recycling bin 31 to provide waterproof protection for the drive unit 33. The bottom of the waterproof protective cover 35 is provided with a window for the output end of the drive unit 33 (e.g., the output end of a hydraulic cylinder or the output end of an electric push rod) to move.

[0043] The waterproof protective cover 35 can prevent the drive component 33 from being affected by rainwater during operation, reduce the probability of damage to the power equipment of the pallet 34, and reduce the maintenance cycle and frequency of the drive component 33.

[0044] Example 9: Reference Figures 1-16 It also includes a navigation module. The chassis 3 is equipped with a navigation module consisting of a lidar, RTK and a visual monitoring system, which is used for precise positioning in open areas.

[0045] Chassis 3 not only has the function of moving the mowing mechanism, but also has a navigation module connected to it. The LiDAR, RTK and visual monitoring system are electrically and communicatively connected to the on-board computer in chassis 3. The LiDAR, RTK and visual monitoring system are used to provide accurate positioning and navigation for the robot in open areas. On this basis, it can also provide early warning and prompts for unexpected intrusions into the work site, thereby increasing the safety of the mowing robot when it is working.

[0046] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. Other modifications can be easily made by those skilled in the art.
