Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, and in particular relates to a creeping crested wheatgrass harvester. Background Technology

[0002] As a forage grass with high nutritional value, the best time to harvest crested wheatgrass is during the heading stage. Under suitable local conditions, it can be harvested two to three times a year.

[0003] Most wheatgrass harvesters on the market currently use manual adjustment of the cutting height, which is complicated to operate and difficult to control precisely. They cannot maintain the best harvesting effect under different conditions. For example, if the wheatgrass harvester cuts too low, it may damage the root system and reduce the regeneration capacity; while if the cutting height is too high, it may affect the harvest yield.

[0004] Therefore, there is an urgent need for a harvesting machine that can adjust the cutting height according to actual needs, so as to ensure both the regeneration capacity of crested wheatgrass and the improvement of harvesting efficiency and yield. Summary of the Invention

It should be understood that such terms can be used interchangeably where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0074] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0075] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0076] like Figure 1 ,and Figure 2 The diagram shown is a structural diagram of a creeping elytra harvester according to an embodiment of the present invention. It includes a cutting housing 101 and a control chamber 4. The cutting housing 101 is slidably disposed on one side of the control chamber 4. An adjustment component 2 is provided on one side of the control chamber 4. One end of the adjustment component 2 is connected to the cutting housing 101 and the other end is connected to the control chamber 4. The device also includes:

[0077] A cutting blade 121 is disposed on one side of the cutting housing 101 and is slidably connected to the cutting housing 101. At least two sets of the cutting blade 121 are provided.

[0078] Elliptical rotating wheel 122 is disposed on one side of the cutting blade 121 and the number of elliptical rotating wheels 122 corresponds to the number of cutting blades 121. The elliptical rotating wheel 122 is connected to one end of the cutting blade 121 in contact, and the major axes of the two elliptical rotating wheels 122 should remain perpendicular in the horizontal direction.

[0079] A power shaft 123 is disposed on one side of the cutting blade 121. The power shaft 123 is fixedly and through-connected to the elliptical wheel 122. Both ends of the power shaft 123 are rotatably connected to the cutting housing 101.

[0080] A spring 124 is disposed on one side of the cutting blade 121 and corresponds to the cutting blade 121. One end of the spring 124 is in contact with the cutting blade 121, and the other end of the spring 124 is in contact with the cutting housing 101.

[0081] In one embodiment of the present invention, a motor drives a power shaft 123 to rotate, which in turn drives an elliptical wheel 122 to rotate. When the elliptical wheel 122 rotates, its major axis pushes the corresponding cutting disc 121 to slide on the cutting housing 101. The spring 124 corresponding to the cutting disc 121 applies resistance to the cutting disc 121 due to its elasticity, forcing the cutting disc 121 to return to its original position. When the major axis of the elliptical wheel 122 pushes the cutting disc 121 to its maximum distance, if the elliptical wheel 122 continues to rotate, the spring 124 will cause the cutting disc 121 to return to its original position, thus forming a reciprocating motion of the cutting disc 121.

[0082] In an embodiment of the present invention, there are two cutting blades 121, and there are also two corresponding elliptical wheels 122 and springs 124. Since the major axes of the two elliptical wheels 122 are kept perpendicular in the horizontal direction, the two cutting blades 121 move in opposite directions when they reciprocate. One side of the cutting blade 121 is serrated, thereby enabling the cutting blade 121 to quickly cut the crested wheatgrass.

[0083] The harvesting height determination unit is used to determine whether the current harvesting height of the cutting component 120 needs to be adjusted based on the tilt angle of the crested wheatgrass, and to generate adjustment signals and maintenance signals.

[0084] The harvesting height correction analysis module is used to obtain the horizontal tilt angle of the cutting component 120 based on the adjustment signal and generate a height correction range;

[0085] The motion distance analysis module is used to generate motion distance values ​​based on the height correction range;

[0086] In this embodiment of the invention, the tilt angle of the crested wheatgrass in the current area of ​​the machine is obtained by remote sensing technology. The tilt angle is used to determine whether the height of the cutting component 120 needs to be adjusted. If adjustment is needed, the tilt angle of the horizontal plane of the cutting component 120 is analyzed, and the height of the cutting component 120 is corrected according to the analysis results. Then, the adjustment component 2 is precisely controlled according to the correction results. In this way, the height of the cutting component 120 can be precisely controlled, so as to maximize the harvest while ensuring the regeneration capacity of crested wheatgrass. This avoids the loss of yield or damage to the regeneration capacity of crested wheatgrass due to abnormal harvesting height, and improves the harvesting efficiency of crested wheatgrass.

[0087] It should be explained that the horizontal tilt angle of the cutting component 120 refers to the degree of tilt of the two ends of the cutting component 120 on the horizontal plane. The degree of tilt will cause the two ends of the cutting component 120 to be inconsistent in height from the ground.

[0088] like Figure 3 As shown, in a preferred embodiment of the present invention, the adjustment component 2 specifically includes:

[0089] The second fixing block 204 is disposed on one side of the cutting housing 101 and is fixedly connected to the cutting housing 101;

[0090] Adjusting rod 202, the adjusting rod 202 is disposed on the second fixed block 204, one end of the adjusting rod 202 is connected through the second fixed block 204 and a damping element is provided at the connection point;

[0091] The slide groove 205 is formed on the adjusting rod 202;

[0092] Slider 203, which is slidably disposed within slide groove 205;

[0093] The first fixing block 201 is rotatably disposed at one end of the adjusting rod 202, and the first fixing block 201 is connected through to one end of the adjusting rod 202. The first fixing block 201 is fixedly connected to the control room 4.

[0094] Support rod 206, both ends of which are rotatably connected to slider 203;

[0095] A hydraulic telescopic rod 207 is provided on one side of the control room 4, and one end of the hydraulic telescopic rod 207 is fixedly connected to the control room 4. The extended end of the hydraulic telescopic rod 207 is rotatably connected to the support rod 206.

[0096] Specifically, the hydraulic telescopic rod 207 is activated through the control room 4. The extended end of the hydraulic telescopic rod 207 drives the support rod 206 to move linearly. The two ends of the support rod 206 drive the slider 203 to slide in the slide groove 205. While the slider 203 is sliding, one end of the adjusting rod 202 is rotatably connected to the first fixed block 201, and the first fixed block 201 is fixedly connected to one side of the control room 4. This causes the other end of the adjusting rod 202 to move in a circle around the center line of the first fixed block 201. Since the adjusting rod 202 is connected to the second fixed block 204, the adjusting rod 202 drives the second fixed block 204 to move in a synchronous circle. The second fixed block 204 drives the cutting housing 101 to move in a synchronous circle. The cutting housing 101 drives the cutting assembly 120 to move in a synchronous circle, thereby realizing the adjustment of the height of the cutting assembly 120 from the ground.

[0097] In this embodiment, the circular motion of the other end of the adjusting rod 202 around the center line of the first fixed block 201 refers to the circular motion in the vertical direction, which can achieve adjustment in the horizontal height. In addition, a damping device is provided between the adjusting rod 202 and the second fixed block 204. This damping device can effectively prevent the cutting housing 101 from making circular motion around the center line of the second fixed block 204 due to gravity, and can also correct the angle between the cutting assembly 120 and the ground by gravity.

[0098] It should be noted that the angle between the cutting component 120 and the ground is the tilt angle generated when the cutting component 120 follows the cutting housing 101 in a circular motion.

[0099] like Figure 1 As shown, in a preferred embodiment of the present invention, the creeping elytra harvester further includes:

[0100] The conveying assembly 5 is located on one side of the control room 4, and one end of the conveying assembly 5 is connected to the cutting housing 101 for conveying the crested wheatgrass on the cutting housing 101.

[0101] Storage chamber 3 is located on one side of control room 4, and one side of storage chamber 3 is slidably connected to one end of conveying assembly 5 for storing crested wheatgrass conveyed by conveying assembly 5;

[0102] Specifically, the harvested wheatgrass on the cutting shell 101 is transported to the storage chamber 3 by the conveying component 5, so as to realize the centralized storage of the harvested wheatgrass, facilitate the subsequent processing of wheatgrass, and improve the harvesting efficiency of wheatgrass.

[0103] like Figure 2 As shown, in a preferred embodiment of the present invention, the creeping elytra harvester further includes:

[0104] A cutting roller 140 is mounted on a cutting housing 101, and both ends of the cutting roller 140 are rotatably connected to the cutting housing 101.

[0105] A power transmission component 141 is disposed at one end of the header roller 140 and is fixedly connected to the header roller 140.

[0106] Specifically, the power motor controlled by the control room 4 drives the power transmission component 141 to rotate, which in turn drives the header drum 140 to rotate. When the header drum 140 rotates, the threaded blades on it push the harvested wheatgrass on the cutting shell 101 to move, concentrating the harvested wheatgrass in one place for easier removal later, thus improving the harvesting efficiency. In addition, when the header drum 140 rotates, the threaded blades on it can also perform simple chopping on the harvested wheatgrass on the cutting shell 101, allowing the harvested wheatgrass to be pre-processed and improving the efficiency of subsequent processing.

[0107] like Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the conveying component 5 specifically includes:

[0108] A conveying port 102 is provided on the cutting housing 101;

[0109] A transmission housing 501, one end of which is rotatably connected to the cutting housing 101, and the other end of which is slidably connected to the storage chamber 3;

[0110] The drive shaft 503 is arranged in a linear array on the transmission housing 501, and both ends of the drive shaft 503 are rotatably connected to the transmission housing 501.

[0111] A conveyor belt 502 is disposed inside the transmission housing 501, and one side of the conveyor belt 502 is engaged with the drive shaft 503.

[0112] Push plate 504, the push plate 504 is disposed on one side of the conveyor belt 502;

[0113] Follower 505, the follower 505 is disposed on one side of the transmission housing 501, and the follower 505 is connected to the transmission shaft 503;

[0114] Chain 506 is disposed on one side of transmission housing 501 and is engaged with driven member 505 and power transmission member 141 for transmitting power from power transmission member 141 to driven member 505.

[0115] Specifically, when the power transmission component 141 rotates, the chain 506 drives the driven component 505 to rotate, the driven component 505 drives the transmission shaft 503 to rotate, the transmission shaft 503 drives the conveyor belt 502 to move, the conveyor belt 502 drives the push plate 504 to move, and the push plate 504 can transport the crested wheat concentrated by the cutting drum 140 through the conveying port 102 and finally transport it to the storage chamber 3, so as to realize the centralized storage of harvested crested wheat, realize the automation of crested wheat harvesting, and improve the harvesting efficiency of crested wheat;

[0116] In addition, at least two drive shafts 503 are provided, and one driven member 505 is provided. The driven member 505 drives one drive shaft 503 to rotate the conveyor belt 502. The conveyor belt 502 can drive the other drive shaft 503 to rotate, so as to realize the long-distance transmission of crested wheatgrass. At the same time, the drive shaft 503 also supports the conveyor belt 502, reducing the instability of the conveyor belt 502 caused by excessively long distances.

[0117] It should be noted that one end of the transmission housing 501 is rotatably connected to the cutting housing 101, and a rotating shaft is provided at the rotatable connection, which provides rotational capability and support, so that one end of the transmission housing 501 is always connected to the conveying port 102 opened on the cutting housing 101; the other end of the transmission housing 501 is slidably connected to the storage chamber 3. When the cutting housing 101 moves, the other end of the transmission housing 501 will extend into the storage chamber 3. Since the storage chamber 3 has a hollow structure, the transmission housing 501 will not be damaged by collision or other reasons.

[0118] In a preferred embodiment of the present invention, the harvesting height determination unit specifically includes:

[0119] Optimal Cutting Height Analysis Module: Obtains the tilt angle of the crested wheatgrass, substitutes the tilt angle of the crested wheatgrass into the height evaluation model, and generates the optimal cutting height value;

[0120] Cutting height determination module: Based on the optimal cutting height value, determine whether the current cutting height needs to be adjusted, and generate adjustment signal and maintenance signal;

[0121] Specifically, by substituting the tilt angle of the crested wheatgrass into the height evaluation model for analysis, the optimal cutting height value of the crested wheatgrass is obtained, and based on the optimal cutting height value of the crested wheatgrass, it is determined whether the current height of the cutting component 120 needs to be adjusted.

[0122] In this embodiment, the optimal cutting height for crested wheatgrass refers to the cutting height that can increase the harvest yield of crested wheatgrass while ensuring its regeneration capacity.

[0123] In a preferred embodiment of the present invention, the optimal cutting height analysis module specifically includes:

[0124] The grassland is divided into several sub-regions. The inclination angle of the crested wheatgrass in the sub-region where the machine is located is obtained. The inclination angle of the crested wheatgrass is substituted into the height evaluation model to generate the optimal cutting height value HX of the crested wheatgrass.

[0125] The expression for the height evaluation model is as follows:

[0126] HX = CX * COS(JC);

[0127] In the expression, JC represents the average tilt angle of all crested wheatgrass in the sub-region where the machine is located, and CX represents the median value of the range of crested wheatgrass lengths to be retained.

[0128] It should be noted that the crested wheatgrass tends to bend in real life. When obtaining the crested wheatgrass tilt angle, an error term should be introduced, such as the degree and direction of the bend, to obtain a representative value of the crested wheatgrass tilt angle, which is the crested wheatgrass tilt angle.

[0129] In this embodiment, the tilt angle of the crested wheatgrass can be obtained by means of a drone equipped with lidar, satellite remote sensing technology, etc.; in addition, the tilt angle is the angle formed by the shape of the crested wheatgrass and the standard line perpendicular to the ground.

[0130] In a preferred embodiment of the present invention, the cutting height determination module specifically includes:

[0131] Obtain the real-time ground clearance value of the cutting component 120, and perform difference processing between the real-time ground clearance value and the optimal cutting height value HX to generate a height deviation value;

[0132] Based on the height deviation value, determine whether there is an abnormality in the cutting height of the cutting component 120, and generate an adjustment signal or a maintenance signal.

[0133] Specifically, determining whether the cutting height of the cutting component 120 is abnormal includes:

[0134] The preset cutting height error range will be compared with the height deviation value. If the height deviation value is within the cutting height error range, the cutting height of the current cutting component 120 does not need to be adjusted, and a maintenance signal will be generated.

[0135] If the height deviation value is outside the cutting height error range, the cutting height of the current cutting component 120 needs to be adjusted, and an adjustment signal is generated.

[0136] In this embodiment, the cutting height error range refers to the error generated by the cutting height of the cutting component 120 during the cutting process. The causes of this error include, but are not limited to, vibration during machine operation and kinetic energy loss caused by friction in the mechanical structure.

[0137] In a preferred embodiment of the present invention, the harvesting height correction analysis module specifically includes:

[0138] Based on the adjustment signal, the horizontal tilt angle of the cutting component 120 is obtained, and the horizontal tilt angle is substituted into the height correction model to generate the height correction range HZ.

[0139] The expression for the height-corrected model is:

[0140]

[0141] In the expression, GP represents the height deviation value, and θ represents the horizontal tilt angle of the cut component;

[0142] In this embodiment, as Figure 7As shown, when adjusting the height of the cutting component 120 using the adjusting component 2, if the horizontal tilt angle of the cutting component 120 (the ground clearance of the two ends of the cutting component 120 is inconsistent) is not horizontal, the path generated by the adjusted cutting height of the cutting component 120 will be tilted, causing the average ground clearance of the cutting component 120 to be less than the adjustment target value. Ultimately, the height adjusted by the cutting component 120 cannot reach the optimal cutting height value. Therefore, it is necessary to correct the distance of the height adjustment of the cutting component 120 so that the ground clearance of the cutting component 120 reaches the optimal cutting height value of the crested wheatgrass. In the height correction model, the principle of its expression is trigonometric functions. Based on the trigonometric function formula, the correction range of the height adjustment distance of the cutting component 120 is generated through the known height deviation value GP and the horizontal tilt angle θ of the cutting component, which is the height correction range HZ.

[0143] It should be added that, Figure 7 H min -GP refers to GP-GP*COSθ in the expression of the highly modified model, H max -GP refers to the expression of the highly modified model.

[0144] In addition, the maximum value of the height correction range HZ is theoretically the correct correction value. However, in actual applications, the retention height of crested wheatgrass is not very high, generally around 5-7 cm (this data is under normal conditions, and the specific data needs to be considered comprehensively based on the growth status and growth environment of crested wheatgrass. This embodiment only indicates that the retention height is not very high in actual applications). If the cutting angle of the cutting blade is too large, it may cause the cutting blade to scrape the ground during the height adjustment process. Therefore, the range value is used.

[0145] In a preferred embodiment of the present invention, the motion distance analysis module specifically includes:

[0146] Substituting the height correction range into the motion distance correction model, we obtain the motion distance range HC;

[0147] The expression for the motion distance correction model is as follows:

[0148] HZ min *γ≤HC≤HZ max *γ;

[0149] In the expression, HZ min This represents the minimum value of the crested wheatgrass cutting height correction range HZ. max γ represents the maximum value of the correction range HZ for the cutting height of crested wheatgrass, and γ represents the influence coefficient of the moving distance of the extended end of the hydraulic telescopic rod on the moving distance of the cutting shell.

[0150] The influence coefficient γ of the travel distance of the extended end of the hydraulic telescopic rod 207 on the travel distance of the cutting shell 101 can be obtained by a linear regression equation. This algorithm is a conventional algorithm and will not be elaborated here.

[0151] When the movement distance range HC is obtained, the control room 4 starts the hydraulic telescopic rod 207 and controls the movement distance of the extended end of the hydraulic telescopic rod 207 according to the movement distance range HC, thereby adjusting the cutting height of the crested wheatgrass;

[0152] In this embodiment, the height correction range of the cutting component 120 is converted into the moving distance of the extended end of the hydraulic telescopic rod 207. By precisely controlling the moving distance of the extended end of the hydraulic telescopic rod 207, the cutting height of the cutting component 120 is precisely controlled, so that the cutting height of the cutting component 120 is always kept within the optimal cutting height value. This achieves the goal of maximizing the harvest while ensuring the regeneration capacity of the crested wheatgrass, avoiding the loss of yield or damage to the regeneration capacity of the crested wheatgrass due to abnormal harvesting height, and improving the harvesting efficiency of the crested wheatgrass.

[0153] It should be noted that the movement distance range HC can be taken as an intermediate value in practical applications. This value can also be reasonably selected within this range based on experience or land conditions. At the same time, this range can also be used as an error range to reduce the risk of the cutting blade scraping the ground during the actual height adjustment process.

[0154] In addition, it should be noted that, in Figure 7 In the process of adjustment, the movement trajectory of the cutting component is not a straight line, but... Figure 7 The reason for using a straight line is as follows: whether the motion trajectory is a straight line or a curve, the starting point and the ending point of the motion trajectory do not change. The ultimate goal is to adjust the cutting assembly 120 to the expected height (the optimal cutting height value HX) through the hydraulic telescopic rod 207.

[0155] The above embodiments of the present invention provide a creeping crested wheatgrass harvester, which precisely adjusts the cutting height of crested wheatgrass by adjusting component 2, thereby maximizing the harvest while ensuring the regeneration capacity of crested wheatgrass, avoiding yield loss or damage to the regeneration capacity of crested wheatgrass due to abnormal harvesting height, and improving the harvesting efficiency of crested wheatgrass.
