Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery and equipment, and in particular to an all-in-one machine for clearing and digging soil from grapevines. Background Art

[0002] In northern regions, due to the cold and dry winter climate, grapevines are usually buried in the soil before winter comes to prevent them from freezing. In spring, as the temperature rises, the antifreeze soil covering the grapevines needs to be removed so that the grapevines can be unearthed and put on the racks for normal growth and management. The removed antifreeze soil will be transported to the center of the grape row to form a soil beam.

[0003] With the development of agricultural mechanization, more and more vineyards have begun to use mechanical soil cleaning. Mechanical soil cleaning has the advantages of high efficiency, low damage rate and low cost. At present, there are many grapevine soil cleaning machines available on the market, such as brush soil cleaning machines, scraper soil cleaning machines, etc. These machines use different working principles and structural designs to quickly remove the anti-freeze soil on the grapevines.

[0013] In order to ensure that the rotary cutter can avoid the grape vines or the grape vine support frame during the soil cleaning process and prevent the rotary cutter from causing damage to the grape vines, as an improvement of the present application, the soil cleaning frame, the rotary cutter frame and the second power transmission device are connected by a clutch device; the clutch device includes: an inner limit cylinder arranged outside the shaft of the second power transmission device, a first inner limit end is arranged at the lower end of the inner limit cylinder, and a first inner limit portion is arranged above the first inner limit end; the lower end of the inner limit cylinder is located below the lower bottom surface of the rotary cutter frame, and the inner limit cylinder is connected to the shaft of the second power transmission device for up and down movement; an outer limit cylinder arranged outside the inner limit cylinder, a first outer limit end is arranged at the lower end of the outer limit cylinder, and a first outer limit portion is arranged at the lower end of the first outer limit end The first outer limit end is located between the soil cleaning frame and the rotary knife frame, the second outer limit end is arranged on the upper end of the outer limit cylinder, the outer limit cylinder is connected to the soil cleaning frame for vertical movement, and the inner limit cylinder is rotatably connected to the outer limit cylinder; an elastic member is sleeved outside the outer limit cylinder and is located between the first outer limit end and the soil cleaning frame; an upper limit end of the rotary knife frame is arranged on the top surface of the rotary knife frame upward, the upper end surface of the upper limit end of the rotary knife frame is the upper limit part of the rotary knife frame, and the upper limit part of the rotary knife frame can cooperate with the first outer limit part for limiting; a lower limit end of the rotary knife frame is arranged on the bottom surface of the rotary knife frame downward, the lower end surface of the lower limit end of the rotary knife frame is the lower limit part of the rotary knife frame, and the lower limit part of the rotary knife frame can cooperate with the first inner limit part for limiting; a toggle system is arranged between the second outer limit end and the soil cleaning frame.

[0014] As an option of the above-mentioned toggle system, the toggle system includes a lifting device, a controller electrically connected to the lifting device, and a non-contact distance sensor electrically connected to the controller, and the non-contact distance sensor is installed on both sides of the soil cleaning frame.

[0015] As another option of the above-mentioned toggle system, the toggle system includes a lever mechanism and a contact sensing mechanism, and the contact sensing mechanism is arranged on the outer sides of both sides of the soil cleaning frame.

[0016] As an option of the above solution of the present application, the soil cleaning device is placed in front of the power device, and the soil scraping device is placed behind the power device.

[0017] As an option of the above solution of the present application, the power output shaft of the power unit is connected to the soil cleaning power input shaft through a universal coupling.

[0018] As an option of the above solution of the present application, the soil scraping power input shaft and the soil cleaning power input shaft are connected through a bevel gear transmission mechanism.

[0019] The technical effects of this application are:

[0020] The grapevine soil cleaning and soil digging machine provided in the present application integrates soil cleaning and soil digging functions into the same machine, reducing the number of equipment and operation complexity, and reducing production costs. The power device of the grapevine soil cleaning and soil digging machine directly drives the soil cleaning device and the soil digging device, reducing energy loss during power transmission and improving operation efficiency.

[0021] In the soil cleaning device of the grapevine soil cleaning and soil digging integrated machine provided in the present application, when the power device is started, its power is transmitted to the soil cleaning power input shaft through the power output shaft. The power is transmitted to the soil cleaning unit through the first power transmission device, and then transmitted to the soil rotary blade through the second and third power transmission devices. The soil rotary blade starts to rotate under the drive of the power to cut, loosen and remove the soil covering the grapevine.

[0022] In order to ensure that the rotary blade can avoid the grapevine or grapevine support frame during the soil cleaning process to prevent the rotary blade from causing damage to the grapevine, the avoidance rod provided in the prior art retracts the rotary blade by hydraulic means, which has the problem of high design cost. In addition, since the hydraulic method only retracts the rotary blade, it is inevitable that the grapevines that are close to the soil cleaning machine body will be damaged. Another method is to adopt a passive rotation method. When the grapevine hits the knife holder, the knife holder rotates under the resistance of the grapevine, but the forward force of the knife holder is too large, which will inevitably damage the grapevine. When the present application senses that the grapevine is approaching through the toggle system, the toggle system drives the inner limit cylinder and the outer limit cylinder to rise, and the soil cleaning frame rotates with the second power transmission device to avoid the grapevine. When the inner limit cylinder and the outer limit cylinder are reset, the positions of the soil cleaning frame and the rotary blade frame remain unchanged, and the rotary blade frame performs soil cleaning work normally. In summary, the embodiments of the present application realize the function of automatically avoiding grape vines during soil cleaning by means of the coordinated action of the inner limit cylinder, the outer limit cylinder, the elastic member, the limit structure on the rotary cutter frame, and the toggle system.

[0038] The following will be combined with the attached Figures 1 to 6 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the protection scope of the present application.

[0039] like Figure 1 An embodiment of the grape vine soil cleaning and digging machine provided in the present application is illustrated. In this embodiment, the grape vine soil cleaning and digging machine includes: a power device 100, a soil cleaning device 200, a soil digging device 300 and walking wheels 400. The power output shaft of the power device 100 is connected to the soil cleaning power input shaft 211 of the soil cleaning device 200 and the soil digging power input shaft 311 of the soil digging device 300.

[0040] For example, in the embodiment of the present application, the power device 100 provides the necessary driving force for the grapevine soil cleaning and digging machine. The power device 100 can generally be an internal combustion engine (such as a gasoline engine or a diesel engine), an electric motor or other high-efficiency power source, and can specifically be an internal combustion tractor or an electric tractor. Those skilled in the art know that the power device 100 is equipped with a speed regulating device, which can adjust the speed according to the needs of the operation. The power output shaft of the power device 100 is provided with a transmission interface, which is convenient for connecting with the power input shaft of the soil cleaning device and the soil digging device.

[0041] The soil cleaning device 200 is mainly responsible for the preliminary removal of soil around the grape vines in preparation for the subsequent soil digging and leveling operations. The soil cleaning device 200 receives power from the power device 100 through the soil cleaning power input shaft 211, and transmits the power to the soil cleaning device 200 through gears, chains or hydraulic transmission, driving it to rotate and clean the soil. Those skilled in the art can also set a height adjustment mechanism on the soil cleaning device 200 according to actual conditions, allowing the operator to adjust the soil cleaning depth according to soil conditions and the growth of the grape vines.

[0042] After the soil cleaning device 200 completes the preliminary cleaning, the soil scraping device 300 is responsible for scraping the soil cleaned near the grape vines to the center of the grape row, forming a soil beam in the center of the grape row. The soil scraping device 300 receives power from the power device 100 through the soil scraping power input shaft 311, drives the soil scraping device 300 to perform a spiral rotation motion, and realizes the transportation of soil near the grape vines to the center to form a soil beam.

[0043] The grapevine soil cleaning and soil digging machine provided in the embodiment of the present application adopts an integrated design, integrating soil cleaning and soil digging functions into the same machine, reducing the number of equipment and operation complexity, and reducing production costs. The power device 100 of the grapevine soil cleaning and soil digging machine directly drives the soil cleaning device 200 and the soil digging device 300, reducing energy loss during power transmission and improving operation efficiency.

[0044] In summary, the grapevine soil cleaning and digging machine of the present application achieves a perfect combination of soil cleaning and digging functions through an integrated design and an efficient power transmission mechanism, effectively solves the problems existing in the prior art, and improves operating efficiency and economic benefits.

[0045] Continue to refer to Figure 2~Figure 3In some embodiments provided in the present application, the soil cleaning device 200 also includes: a soil cleaning frame 221 fixedly connected to the main frame; a soil cleaning unit connected to the soil cleaning power input shaft 211 through a first power transmission device 212, a plurality of soil rotary knives 230 installed on the rotary knife frame 222, the soil rotary knives 230 include a soil rotary shaft 231 and a plurality of cutters 232 arranged on the periphery of the soil rotary shaft 231, the first power transmission device 212 is connected to the second power transmission device 213, and the soil rotary shaft 231 is connected to the second power transmission device 213 through a third power transmission device 214.

[0046] For example, in Figure 1 In the illustrated embodiment, the support wheels 400 are the moving parts of the soil cleaning device, allowing the entire soil cleaning device 200 to move with the power device 100 in the vineyard.

[0047] The first power transmission device 212 is responsible for transmitting power from the power device 100 to the core component of the soil cleaning device 200, namely the soil cleaning unit. The first power transmission device 212 can be implemented by a belt, a chain or a directly connected transmission shaft, and those skilled in the art can select and arrange it according to the specific situation.

[0048] The soil cleaning unit is the core component for performing soil cleaning operations. The soil cleaning unit includes one or more rotary knives 230. The soil cleaning unit removes the antifreeze soil covering the grape vines by rotating the rotary knives 230. The rotary knives 230 are installed on the rotary knife frame 222, and the soil is cut and removed by the combination of the rotary shaft 231 and multiple knives 232. In the specific transmission process, the third power transmission device 214 further transmits power from the second power transmission device 213 to the rotary shaft 231, driving the rotary knives 230 to rotate. The second power transmission device 213 acts as an intermediate link to distribute power from the first power transmission device 212 to different rotary knives 230.

[0049] Continue to refer to Figure 1 In some embodiments of the present application, the soil scraping device includes a soil scraping power input shaft 311, two soil scraping spiral blades 322 with opposite movement directions arranged on the soil scraping spiral blade shaft 321, and the soil scraping spiral blade shaft 321 is connected to the soil scraping power input shaft 311.

[0050] For example, in Figure 1 In the illustrated embodiment, the soil-scraping power input shaft 311 is the power inlet of the soil-scraping device 300, which is responsible for receiving power from the power device 100 and transmitting it to the soil-scraping power input shaft 311 of the soil-scraping device. The soil-scraping power input shaft 311 can be connected to the power device 100 through a transmission device in the form of a gear box, chain drive or belt drive.

[0051] Two soil scraping spiral blades 322 with opposite movement directions are arranged on the soil scraping spiral blade shaft 321. The soil scraping spiral blades 322 transport the soil near the grape vines processed by the soil cleaning device to the center of the grape row through rotational movement, forming a soil beam in the center of the grape row. The soil scraping spiral blade shaft 321 is connected to the soil scraping power input shaft 311, which is responsible for transmitting power to each soil scraping spiral blade 322 to drive the soil scraping spiral blade 322 to rotate.

[0052] Optionally, the soil scraping spiral blade 322 and the soil scraping spiral blade shaft 321 are provided in two, and the two shafts on both sides of the soil scraping device move in opposite directions through bevel gears, so as to transport the soil on both sides to the center. Alternatively, the soil scraping spiral blade 322 is provided in two opposite spiral directions, and the two soil scraping spiral blades 322 with opposite spiral directions are provided on one soil scraping spiral blade shaft 321. When the soil scraping spiral blade shaft 321 moves, the soil on both sides of the soil scraping device 300 can also be transported to the center to form a soil beam.

[0053] The first power transmission device 212, the second power transmission device 213, and the third power transmission device 214 described in the above embodiment are one of the "shaft-bevel gear" transmission device, the "belt-pulley" transmission device, or the "gear-chain" rotating device. The "shaft-bevel gear" transmission device realizes power transmission through bevel gears (also called bevel gears or spiral bevel gears). The tooth surface of the bevel gear is conical, which can mesh with each other and transmit torque. Due to the meshing method of the bevel gears, they can change the direction of power transmission and are usually used in occasions where the power transmission axis needs to be changed. In the soil cleaning device, the "shaft-bevel gear" transmission device may be used to transmit power from a horizontal axis to a vertical axis, or to transmit power between axes at different angles. The "belt-pulley" transmission device realizes power transmission through a belt and a pulley. The belt is wound around two or more pulleys, and when the driving wheel rotates, the driven wheel is driven to rotate through the belt. Belt transmission has the advantages of simple structure, smooth transmission, and low noise. In a soil cleaning device, a "belt-and-pulley" transmission may be used to transfer power from the power unit to the soil cleaning unit, especially in situations where power needs to be transmitted over long distances or shocks need to be cushioned. A "gear-and-chain" transmission is a transmission that uses gears and chains to achieve power transmission. The chain consists of a series of links that can be wound around and mesh with gears. Gear-and-chain transmission has the advantages of high transmission efficiency, high torque transmission, and compact structure. In a soil cleaning device, a "gear-and-chain" transmission may be used in situations where large torque needs to be transmitted or the transmission ratio needs to be precisely controlled, such as driving rotating parts such as soil rotary cutters.

[0054] In the actual design of the grapevine soil cleaning and digging machine, one or more of the above transmission methods may be selected for combination according to specific needs and transmission conditions. For example, the first power transmission device 212 adopts a "belt-wheel" or "shaft-bevel gear" transmission device to achieve long-distance power transmission; the second power transmission device 213 adopts a "shaft-bevel gear" transmission device to change the power transmission direction; the third power transmission device 214 adopts a "gear-chain" transmission device to provide stable torque output to the soil rotary cutter and other components. The first power transmission device 212, the second power transmission device 213, and the third power transmission device 214 provided in the embodiment of the present application are all designed as bevel gear transmission connections.

[0055] In an optional embodiment, a gearbox is arranged between the soil cleaning power input shaft 211, the first power transmission device 212, the second power transmission device 213, and the third power transmission device 214. Those skilled in the art will know that the gearbox is mainly used to convert and distribute the input power to meet the speed and torque requirements of different components. By setting up a gearbox, functions such as power deceleration, speed increase, reversal, and distribution can be achieved. In the grapevine soil cleaning and digging machine provided in the embodiment of the present application, those skilled in the art can select different gearboxes according to the needs of power transmission, and set the transmission ratio to ensure that the matching relationship between the transmission ratios is reasonable to meet the speed and torque requirements of different components.

[0056] Reference Figure 4~Figure 5 In order to ensure that the rotary blade 230 can avoid the grape vines during the soil cleaning process and prevent the rotary blade 230 from causing damage to the grape vines, in a preferred embodiment of the present application, the soil cleaning frame 221, the rotary blade frame 222 and the second power transmission device 213 are connected via a clutch device 240;

[0057] The clutch device 240 includes: an inner limit cylinder 241 arranged on the shaft outer surface of the second power transmission device 213, a first inner limit end 2411 is arranged at the lower end of the inner limit cylinder 241, and a first inner limit portion 2412 is arranged above the first inner limit end 2411; the lower end of the inner limit cylinder 241 is located below the lower bottom surface of the rotary cutter frame 222, and the inner limit cylinder 241 is connected to the shaft of the second power transmission device 213 for vertical movement; an outer limit cylinder 242 arranged outside the inner limit cylinder 241, a first outer limit end 2421 is arranged at the lower end of the outer limit cylinder 242, a first outer limit portion 2423 is arranged at the lower end of the first outer limit end 2421, the first outer limit end 2421 is located between the soil cleaning frame 221 and the rotary cutter frame 222, a second outer limit end 2422 is arranged at the upper end of the outer limit cylinder 242, and the outer limit cylinder 242 is connected to the shaft of the second power transmission device 213 for vertical movement. The soil cleaning frame 221 is connected to move up and down, and the inner limit cylinder 241 is rotatably connected to the outer limit cylinder 242; an elastic member 243 is sleeved outside the outer limit cylinder 242 and is located between the first outer limit end 2421 and the soil cleaning frame 221; an upper limit end 2221 of the rotary knife frame is arranged on the top surface of the rotary knife frame 222, and the upper end surface of the upper limit end 2221 of the rotary knife frame is the upper limit portion 2222 of the rotary knife frame, and the upper limit portion 2222 of the rotary knife frame can cooperate with the first outer limit portion 2423 for limiting; a lower limit end 2223 of the rotary knife frame is arranged on the bottom surface of the rotary knife frame 222, and the lower end surface of the lower limit end 2223 of the rotary knife frame is the lower limit portion 2224 of the rotary knife frame, and the lower limit portion 2224 of the rotary knife frame can cooperate with the first inner limit portion 2412 for limiting; a toggle system 244 is arranged between the second outer limit end 2422 and the soil cleaning frame 221.

[0058] In this embodiment, the inner limit cylinder 241 is sleeved on the shaft of the second power transmission device 213 and connected to the shaft for up and down movement, allowing the inner limit cylinder 241 to move up and down relative to the shaft of the second power transmission device 213 when subjected to external force, but cannot rotate relative to the shaft of the second power transmission device 213;

[0059] The outer limiting cylinder 242 is sleeved outside the inner limiting cylinder 241 and connected to the soil cleaning frame 221 for vertical movement. A circumferential limiting protrusion 2424 is provided on the upper part of the outer limiting cylinder 242, so that the outer limiting cylinder 242 cannot rotate circumferentially on the soil cleaning frame 221. The elastic member 243 can be set as a spring or a similar element. The elastic member 243 is set between the first limiting end 2421 and the soil cleaning frame 221 to provide a reset force for the outer limiting cylinder 242, so that in a natural state, the first outer limiting portion 2423 of the outer limiting cylinder 242 cooperates with the upper limiting end 2221 of the rotary cutter frame to limit, so that the positions of the soil cleaning frame 221 and the rotary cutter frame 222 are relatively fixed, and the first inner limiting portion 2412 is separated from the lower limiting portion 2224 of the rotary cutter frame, so that the shaft of the second power transmission device 213 can rotate relative to the rotary cutter frame 222. The toggle system 244 can be set as a lever with a sensor, a connecting rod, a motor drive mechanism, a hydraulic drive mechanism, etc. The specific forms of the first inner limit portion 2412, the first outer limit portion 2423, the upper limit portion 2222 of the rotary cutter frame, and the lower limit portion 2224 of the rotary cutter frame can be various, such as ratchet teeth, concave-convex grooves, limit teeth, etc., without specific limitation, but it can be understood that the first inner limit portion 2412, the lower limit portion 2224 of the rotary cutter frame, the first outer limit portion 2423, and the upper limit portion 2222 of the rotary cutter frame cooperate with each other to achieve power transmission or locking. The above-mentioned rotation connection method can be a bearing connection.

[0060] like Figure 4~Figure 5In the normal state, the elastic member 243 is in a natural state. Under the action of the elastic member 243, the first outer limiting portion 2423 arranged on the lower end surface of the outer limiting cylinder 242 cooperates with the upper limiting portion 2222 of the rotary cutter frame 222 which faces upward from the top surface of the rotary cutter frame 222, and the outer limiting cylinder 242 and the soil cleaning frame 221 cannot rotate. At this time, the first inner limiting portion 2412 is separated from the lower limiting portion 2224 of the rotary cutter frame, so that the shaft of the second power transmission device 213 can rotate relative to the rotary cutter frame 222. When the toggle system 244 detects that the grapevine or the grapevine supporting rod is close to the soil cleaning device 200, the toggle system 244 raises the height of the inner limiting cylinder 241 and the outer limiting cylinder 242, so that the first outer limiting portion 2423 is separated from the upper limiting portion 2222 of the rotary cutter frame 222 with the top surface facing upward. At this time, the first inner limiting portion 2412 cooperates with the lower limiting portion 2224 of the rotary cutter frame, and the shaft of the second power transmission device 213 can drive the inner limiting cylinder 241 to rotate, and drive the rotary cutter frame 222 to rotate, so that the rotary cutter 230 rotates with the soil cleaning frame 221. In this way, grape vines or grape vine supporting rods can be avoided. An optional method is to set an angle sensor between the axes of the soil cleaning frame 221 and the second power transmission device 213. When the soil cleaning frame 221 rotates to a specific angle, for example, after rotating 180° during the overall walking process of the integrated machine, the toggle system 244 controls the inner limit cylinder 241 and the outer limit cylinder 242 to reset, so that the first outer limit part 2423 and the upper limit part 2222 of the rotary knife frame facing upward on the top surface of the rotary knife frame 222 are matched again, and the first inner limit part 2412 and the lower limit part 2224 of the rotary knife frame are separated again.

[0061] The avoidance rod provided in the prior art uses hydraulic means to retract the rotary blade, which has the problem of high design cost. In addition, since the hydraulic means only retracts the rotary blade, it is inevitable that the grapevines that are close to the soil cleaning machine body will be damaged. Another method is to use a passive rotation method. When the grapevine hits the knife holder, the knife holder rotates under the resistance of the grapevine, but the forward force of the knife holder is too large, which will inevitably damage the grapevine. When the present application senses that the grapevine is approaching through the toggle system 244, the toggle system 244 drives the inner limit cylinder 241 and the outer limit cylinder 242 to rise, and the soil cleaning frame 221 rotates with the second power transmission device 213 to avoid the grapevine. When the inner limit cylinder 241 and the outer limit cylinder 242 are reset, the positions of the soil cleaning frame 221 and the rotary blade frame 222 remain unchanged, and the rotary blade frame 222 performs soil cleaning work normally. In summary, the embodiment of the present application realizes the function of the rotary knife 230 automatically avoiding the grape vines during the soil cleaning process through the coordinated action of the inner limit cylinder 241, the outer limit cylinder 242, the elastic member 243, the limit structure on the rotary knife frame 222 and the toggle system 244.

[0062] like Figure 4~Figure 6In one embodiment, the toggle system 244 is a lifting device, and the toggle system 244 includes a lifting device 2441, a controller 2442 electrically connected to the lifting device 2441, and a non-contact distance sensor 2443 electrically connected to the controller 2442, and the non-contact distance sensor 2443 is installed on both sides of the soil cleaning frame 221.

[0063] In this embodiment, the lifting device 2441 is an actuator of the toggle system 244, which drives the outer limit cylinder 242 to perform lifting and lowering motion in the axial direction of the second power transmission device 213 according to the instruction of the controller 2442. The lifting device 2441 can adopt an electric push rod, a hydraulic cylinder, a screw drive, etc. The controller 2442 is used to receive the signal sent by the non-contact distance sensor 2443, and send a control signal to the lifting device 2441 according to the preset logic to determine whether to drive the lifting device 2441 to perform lifting and lowering motion. The controller 2442 can be implemented by hardware such as a single-chip microcomputer, a PLC or a dedicated control chip. The non-contact distance sensor 2443 can use infrared, ultrasonic, laser or radar principles to realize the measurement function. The non-contact distance sensor 2443 is installed on both sides of the soil cleaning frame 221 so as to be able to detect the distance between the two sides of the soil cleaning frame and the grapevine or the grapevine support rod in real time. The non-contact distance sensor 2443 can measure the distance between the two side edges of the soil cleaning frame 221 and the grape vines or grape vine support rods in real time, and convert the measurement results into electrical signals and send them to the controller 2442. The controller determines whether the rotary knife 230 needs to avoid the grape vines based on these signals. When the distance between the two side edges of the soil cleaning frame 221 and the grape vines or grape vine support rods is less than the set threshold, the controller 2442 controls the lifting device 2441 to drive the lower end face of the outer limit cylinder 242 to disengage from the first inner limit end 2411.

[0064] Optionally, the toggle system 244 includes a lever mechanism and a contact sensing mechanism, and the contact sensing mechanism is arranged on the outer sides of the two sides of the soil cleaning frame 221. The lever mechanism plays a role in transmitting and amplifying force in the toggle system 244. When the contact sensing mechanism detects a grapevine or other obstacle, it transmits the force or displacement information to the outer limit cylinder 242 through the lever mechanism. Thereby, the lower end surface of the outer limit cylinder 242 is driven to disengage from the first inner limit end 2411.

[0065] In an optional embodiment, the soil cleaning device 200 is placed in front of the power device 100 , and the soil scraping device 300 is placed behind the power device 100 .

[0066] In an optional embodiment, the power output shaft of the power device 100 is connected to the soil cleaning power input shaft 211 via a universal coupling.

[0067] In an optional embodiment, the soil scraping power input shaft 311 is connected to the soil cleaning power input shaft 211 via a bevel gear transmission mechanism.
