[0075] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0076] like Figure 1 ,and Figure 2 As shown, it is a structural diagram of a creeping lycopene harvester provided by an embodiment of the present invention, comprising a cutting housing 101 and a control room 4, wherein the cutting housing 101 is slidably arranged on one side of the control room 4, and an adjustment component 2 is arranged on one side of the control room 4, wherein one end of the adjustment component 2 is connected to the cutting housing 101 and the other end is connected to the control room 4, and further comprising:
[0077] A cutting blade 121, wherein the cutting blade 121 is disposed on one side of the cutting housing 101 and is slidably connected to the cutting housing 101, and at least two groups of the cutting blades 121 are provided;
[0078] An elliptical rotating wheel 122, wherein the elliptical rotating wheel 122 is arranged on one side of the cutting blade 121 and the number of the elliptical rotating wheels 122 corresponds to the number of the cutting blades 121, the elliptical rotating wheel 122 is abutted against one end of the cutting blade 121, and the long axes of the two elliptical rotating wheels 122 should be kept vertical in the horizontal direction;
[0079] A power shaft 123, wherein the power shaft 123 is disposed on one side of the cutting blade 121, the power shaft 123 is fixedly connected to the elliptical rotating wheel 122, and both ends of the power shaft 123 are rotatably connected to the cutting housing 101;
[0080] A spring 124, wherein the 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, the power shaft 123 is driven to rotate by a motor, and the power shaft 123 drives the elliptical rotating wheel 122 to rotate. When the elliptical rotating wheel 122 rotates, the long axis of the elliptical rotating wheel 122 pushes the corresponding cutting blade 121 to slide on the cutting housing 101, and the spring 124 corresponding to the cutting blade 121 exerts resistance to the cutting blade 121 due to its own elasticity, forcing the cutting blade 121 to reset; when the long axis of the elliptical rotating wheel 122 pushes the cutting blade 121 to the farthest distance, if the elliptical rotating wheel 122 continues to rotate, the spring 124 resets the cutting blade 121, forming a reciprocating motion of the cutting blade 121;
[0082] In the embodiment of the present invention, the number of the cutting blades 121 is two, and the number of the corresponding elliptical wheels 122 and the springs 124 is also two. Since the long axes of the two elliptical wheels 122 remain vertical in the horizontal direction, the two cutting blades 121 move in opposite directions when performing reciprocating motion, and one side of the cutting blade 121 is serrated, so that the cutting blade 121 can quickly cut the saltwort.
[0083] A harvesting height judgment unit, used to judge whether the current harvesting height of the cutting assembly 120 needs to be adjusted according to the inclination angle of the Elymus salsa, and to generate an adjustment signal and a maintenance signal;
[0084] A harvesting height correction analysis module, for obtaining a horizontal plane inclination angle of the cutting assembly 120 based on an adjustment signal and generating a height correction range;
[0085] A motion distance analysis module is used to generate a motion distance value according to a height correction range;
[0086] In the embodiment of the present invention, the inclination angle of the alkali grass in the current area of the machine is obtained by remote sensing technology, and whether the height of the cutting component 120 needs to be adjusted is judged by the inclination angle. If adjustment is required, the inclination 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 result, and then the adjustment component 2 is precisely controlled according to the correction result, so that the height of the cutting component 120 can be precisely regulated to achieve the maximum harvest while ensuring the regeneration ability of the alkali grass, avoid the loss of yield of the alkali grass or damage to the regeneration ability of the alkali grass due to abnormal harvesting height, and improve the harvesting efficiency of the alkali grass;
[0087] It should be explained that the horizontal plane inclination angle of the cutting assembly 120 refers to the degree of inclination of the two ends of the cutting assembly 120 on the horizontal plane, and the degree of inclination will cause the heights of the two ends of the cutting assembly 120 from the ground to be inconsistent.
[0088] like Figure 3 As shown, as a preferred embodiment of the present invention, the adjustment component 2 specifically includes:
[0089] A second fixing block 204, which is disposed on one side of the cutting housing 101 and is fixedly connected to the cutting housing 101;
[0090] An adjusting rod 202, wherein the adjusting rod 202 is disposed on the second fixing block 204, one end of the adjusting rod 202 is connected through the second fixing block 204 and a damping member is disposed at the connection;
[0091] A slide groove 205, wherein the slide groove 205 is provided on the adjusting rod 202;
[0092] A slider 203, wherein the slider 203 is slidably disposed in a slide groove 205;
[0093] A first fixing block 201, wherein 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 one end of the adjusting rod 202, and the first fixing block 201 is fixedly connected to the control chamber 4;

[0096] Specifically, the hydraulic telescopic rod 207 is started through the control room 4, and the extended end of the hydraulic telescopic rod 207 drives the support rod 206 to perform linear motion, and the two ends of the support rod 206 drive the slider 203 to slide in the slide groove 205. While the slider 203 slides, since 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, the other end of the adjusting rod 202 performs circular motion around the center line of the first fixed block 201. Because the adjusting rod 202 is connected to the second fixed block 204, the adjusting rod 202 drives the second fixed block 204 to perform synchronous circular motion, the second fixed block 204 drives the cutting shell 101 to perform synchronous circular motion, and the cutting shell 101 drives the cutting assembly 120 to perform synchronous circular motion, 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 fixing block 201 refers to the circular motion in the vertical direction, and the circular motion in this direction can achieve the adjustment in the horizontal height; in addition, a damping device is provided between the adjusting rod 202 and the second fixing block 204, and the damping device can effectively prevent the cutting housing 101 from performing a circular motion around the center line of the second fixing block 204 due to gravity, and can also correct the angle between the cutting assembly 120 and the ground through gravity;
[0098] It should be noted that the angle between the cutting assembly 120 and the ground is the inclination angle generated when the cutting assembly 120 follows the cutting housing 101 to perform circular motion.
[0099] like Figure 1 As shown, as a preferred embodiment of the present invention, the creeping Elymus salsa harvester also includes:
[0100] A conveying assembly 5, wherein the conveying assembly 5 is arranged at one side of the control chamber 4, and one end of the conveying assembly 5 is connected to the cutting shell 101, and is used to convey the Elymus salsa on the cutting shell 101;

[0105] A power transmission member 141, wherein the power transmission member 141 is disposed at one end of the cutting drum 140 and is fixedly connected to the cutting drum 140;
[0106] Specifically, the control room 4 controls the power motor to drive the power transmission component 141 to rotate, and the power transmission component 141 drives the cutting table drum 140 to rotate. When the cutting table drum 140 rotates, the threaded blades arranged on the cutting table drum 140 will push the Elymus salsa harvested on the cutting shell 101 to move, so that the Elymus salsa harvested on the cutting shell 101 is concentrated in one place, which is convenient for the subsequent removal of the Elymus salsa harvested on the cutting shell 101, thereby improving the harvesting efficiency of the Elymus salsa; in addition, when the cutting table drum 140 rotates, the threaded blades on the cutting table drum 140 can also perform simple shredding processing on the Elymus salsa harvested on the cutting shell 101, so that the harvested Elymus salsa can be pre-processed in advance, thereby improving the efficiency of subsequent processing of the Elymus salsa.

[0116] In addition, at least two transmission shafts 503 are provided, and the number of driven members 505 is one. The driven member 505 drives one transmission shaft 503 to realize the rotation of the conveyor belt 502, and the conveyor belt 502 can drive another transmission shaft 503 to rotate, so as to realize the long-distance transmission of the alkali grass; at the same time, the transmission shaft 503 also supports the conveyor belt 502, reducing the instability of the conveyor belt 502 caused by the excessive distance of the conveyor belt 502;
[0117] It should be noted that one end of the transmission shell 501 is rotatably connected to the cutting shell 101, and a rotating shaft is provided at the rotating connection, which provides rotation capability and support at the same time, so that one end of the transmission shell 501 is always connected to the delivery port 102 opened on the cutting shell 101; the other end of the transmission shell 501 is slidably connected to the storage chamber 3. When the cutting shell 101 moves, the other end of the transmission shell 501 will extend into the storage chamber 3.

[0127] In the expression, JC represents the average value of the inclination angles of all Elymus salsa in the sub-area where the machine is located, and CX represents the middle value of the required retention length range of Elymus salsa;
[0128] It should be noted that Elymus salsa has a bending phenomenon in real life. When obtaining the inclination angle of Elymus salsa, error terms should be introduced, such as the bending degree and bending direction of Elymus salsa, and finally the representative value of the inclination angle of Elymus salsa is obtained, which is the inclination angle of Elymus salsa.

[0134] A cutting height error range is preset, and the height deviation value is compared with the cutting height error range. If the height deviation value is within the cutting height error range, the cutting height of the current cutting assembly 120 does not need to be adjusted, and a maintenance signal is generated;
[0135] If the height deviation value is outside the cutting height error range, the current cutting height of the cutting assembly 120 needs to be adjusted, and an adjustment signal is generated;
[0136] In this embodiment, the cutting height error range refers to the error caused by the cutting height of the cutting component 120 during the cutting process of the machine. The causes of this error include but are not limited to vibration during operation of the machine, kinetic energy loss caused by friction of the mechanical structure, etc.
[0137] As a preferred embodiment of the present invention, the harvesting height correction analysis module specifically includes:
[0138] Based on the adjustment signal, the horizontal plane inclination angle of the cutting assembly 120 is obtained, and the horizontal plane inclination angle is substituted into the height correction model to generate the height correction range HZ;
[0139] Among them, the expression of the height correction model is:
[0140]
[0141] In the expression, GP represents the height deviation value, and θ represents the horizontal plane inclination angle of the cutting component;
[0142] In this embodiment, if Figure 7As shown, when the height of the cutting component 120 is adjusted by the adjustment component 2, if the horizontal plane inclination angle of the cutting component 120 (the heights from the ground at both ends of the cutting component 120 are inconsistent) is not in a horizontal state, the path generated by the cutting height adjusted by the cutting component 120 will be tilted, so that the average height from the ground adjusted by the cutting component 120 is less than the adjustment target value, and ultimately the height adjusted by the cutting component 120 cannot reach the optimal cutting height value, then the height adjustment distance of the cutting component 120 needs to be corrected so that the height from the ground of the cutting component 120 can reach the optimal cutting height value of the saltwort; in the height correction model, the principle of its expression is trigonometric function, based on the trigonometric function formula, through the known height deviation value GP and the horizontal plane inclination angle θ of the cutting component, the correction range of the height adjustment distance of the cutting component 120 is generated, that is, the height correction range HZ;
[0143] It is necessary to add that Figure 7 Medium H min -GP refers to GP-GP*COSθ in the expression of the height correction model, H max -GP refers to the expression of the height correction model
[0144] In addition, the maximum value of the height correction range HZ is theoretically the correct correction value, but in actual applications, the retention height of Elymus salsa is not very high, generally about 5-7 cm (this data is the data under normal conditions, and the specific data needs to be considered comprehensively according to the growth state and growth environment of Elymus salsa. This embodiment only indicates that the retention height is not very high in actual applications). If the bevel angle of the cutting blade is too large, the cutting blade may scrape the ground during the height adjustment process, so the range value is used;
[0145] As a preferred embodiment of the present invention, the movement distance analysis module specifically includes:
[0146] Substitute the height correction range into the motion distance correction model to obtain the motion distance range HC;
[0147] Wherein, the expression of the motion distance correction model is:
[0148] HZ min *γ≤HC≤HZ max *γ;
[0149] In the expression, HZ min It indicates the minimum value of the correction range of the cutting height of Elymus salsa, HZ max represents the maximum value of the correction range HZ of the cutting height of the lycopene grass, 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 moving distance of the extended end of the hydraulic telescopic rod 207 on the moving distance of the cutting housing 101 can be obtained by a linear regression equation. This algorithm is a conventional algorithm and will not be described here.
[0151] When the movement distance range HC is obtained, the control room 4 starts the hydraulic telescopic rod 207 and controls the moving 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 lycopene grass;
[0152] In this embodiment, the height correction range of the cutting assembly 120 is converted into the moving distance of the extended end of the hydraulic telescopic rod 207. By accurately controlling the moving distance of the extended end of the hydraulic telescopic rod 207, the cutting height of the cutting assembly 120 is accurately controlled, so that the cutting height of the cutting assembly 120 is always maintained within the optimal cutting height value, and the maximum harvest amount is achieved while ensuring the regeneration ability of the alkali grass, avoiding the loss of yield of the alkali grass due to abnormal harvesting height or damage to the regeneration ability of the alkali grass, thereby improving the harvesting efficiency of the alkali grass.
[0153] It should be noted that the movement distance range HC can take an intermediate value in practical applications. The value can also be reasonably taken within the range based on experience or land conditions. The 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 Figure 7 In the process of adjustment, the motion trajectory of the cutting component is not a straight line, but Figure 7 The reason for using a straight line is as follows: no matter the motion trajectory is a straight line or a curve, the starting point and the end point of the motion trajectory do not change, and 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 embodiment of the present invention provides a creeping type Elymus salsa harvester, which can accurately adjust the cutting height of the Elymus salsa by adjusting the component 2, thereby maximizing the harvest while ensuring the regeneration ability of the Elymus salsa, avoiding the loss of yield of the Elymus salsa or damage to the regeneration ability of the Elymus salsa due to abnormal harvesting height, and improving the harvesting efficiency of the Elymus salsa.
