[0047] Specifically, Figure 1-Figure 5 As shown, the ridge breaking and turning mechanism 3 includes a ridge breaking and soil turning component installed on the inner side of the traveling frame 1 for breaking the ridge with the straw roots remaining thereon and turning up the straw roots with soil, and also includes an arc-shaped baffle 311 fixedly installed on the inner side of the traveling frame 1 for assisting in turning up the soil and the straw roots and a photoelectric sensor 312 for detecting the position of the straw roots;

[0048] The ridge breaking and soil turning assembly includes a limiting groove 31 extending through both sides of the traveling frame 1 and a cylinder 34 fixedly installed at both ends of the top of the inner side of the traveling frame 1, and also includes an arc-shaped baffle 311 and a photoelectric sensor 312 fixedly installed on the inner side of the traveling frame 1. Slide seats 32 are slidably installed inside the two limiting grooves 31, wherein the axial cross section of the limiting groove 31 in the top view direction is a cross-shaped structure, and a limit block is fixedly provided on the outer side of the slide seat 32 to prevent the slide seat 32 from being separated from the limiting groove 31, and a rotating shaft 33 is rotatably installed between the two slide seats 32, wherein a receiving groove is provided at one end of one of the slide seats 32, and a motor 1 for driving the rotating shaft 33 to rotate is fixedly installed inside the receiving groove;

[0049] A plurality of circularly evenly distributed arc flaps 36 are fixedly provided in the middle of the outer side of the rotating shaft 33, wherein the arc flaps 36 will not affect the normal operation of the photoelectric sensor 312 during the circular rotation around the rotating shaft 33, thereby ensuring the accurate positioning of the straw root, and the arc baffle 311 is on the concentric circle of the movement trajectory of the arc flap 36, and the bottom end of the arc baffle 311 will not contact the part of the straw root exposed on the ground, so that the turned-up straw root can be sent to the soil removal and conveying station under the restriction of the arc baffle 311, and a supporting arc rod 39 is fixedly connected between two adjacent arc flaps 36, which can be used to support the arc Rod 39 is used to assist the arc flap 36 in supporting so as to improve the bearing capacity of the arc flap 36 in the process of breaking ridges and turning over soil, and the supporting arc rods 39 at the corresponding positions can be designed to be arranged in multiple equidistant positions, so that after the straw roots turned up with the soil collide with the supporting arc rods 39 in the turning direction, the straw roots and the soil are pre-separated to a certain extent, annular grooves are provided at the positions of the cylinder 1 34 at both ends of the outer side of the rotating shaft 33, and the telescopic end of the cylinder 1 34 is fixedly connected with a ring block 35 movably sleeved in the corresponding annular groove, and the outer ends of the rotating shaft 33 are sleeved with baffles 310 fixedly connected to the corresponding ends of the arc flap 36;

[0050] A notch 37 is provided at one end of each arc-shaped flap 36 away from the rotating shaft 33, and a ridge-breaking roller 38 is rotatably installed inside the notch 37, wherein a plurality of evenly distributed V-shaped protrusions can be provided on the outer side of the ridge-breaking roller 38, and the tip of the V-shaped protrusion is made to be consistent with the rotation direction of the ridge-breaking roller 38, so as to improve the ridge-breaking effect, and a sinking groove 313 is provided at the position of each arc-shaped flap 36 on the outer side of the baffle plate 310, and a driving wheel 314 is rotatably installed at both ends of the sinking groove 313, and a belt is connected between the two driving wheels 314, and a plurality of guide rollers 315 for limiting the belt are rotatably installed inside the sinking groove 313, and the rotatably installed guide rollers 315 can be used to prevent the belt from directly contacting the inner side of the sinking groove 313, and the static friction force generated when the belt contacts the guide roller 315 is converted into rolling friction, thereby reducing the wear of the belt during the transmission process;

[0051] The driving wheel 314 corresponding to the corrugating roller 38 rotates synchronously with the corrugating roller 38 , and a second motor is fixedly installed on the outer side of the baffle 310 at a position corresponding to the driving wheel 314 away from the corrugating roller 38 , and the second motor is used to drive the corresponding driving wheel 314 to rotate.

[0052] It should be noted that, in the process of collecting the roots of the straw remaining in the field, as the traveling frame 1 moves under the drive of the external power device, the motor 2 will drive the ridge breaking roller 38 to rotate continuously at a high speed, and the arc-shaped flap 36 in the initial state is in the state of Figure 2In the state shown, whenever the photoelectric sensor 312 detects the root of the straw in the direction of travel of the walking frame 1, it transmits a signal to the control end, which controls the motor to drive the rotating shaft 33 to rotate 90°, and uses the arc-shaped flap 36 (i.e. Figure 2 The soil with the straw roots is turned up and moved upward under the restriction of the arc baffle 311 to prevent the straw roots from directly detaching from the arc flap 36 during the turning process and being unable to be transported to the soil removal and conveying station for further processing;

[0053] In addition, in the process of collecting the straw roots remaining in the field, if the buried section of the straw roots is deep, it is necessary to control the cylinder 34 to drive the rotating shaft 33 to adjust the longitudinal depth along the limiting groove 31 to meet the needs of collecting straw roots at different buried depths.

[0054] Specifically, Figure 2 and Figure 6-Figure 8 As shown, the soil removal conveying mechanism 4 is composed of a conveying part for conveying the turned-up straw roots and an impact part for repeatedly impacting the straw roots with soil, and is used to clean up the soil remaining at the straw roots while conveying the straw roots with soil. The conveying part includes a transverse plate 41 fixed on both sides of the inner cavity of the walking frame 1 and a conveying chain 43 installed on both sides of the inner cavity of the walking frame 1. The opposite sides of the two transverse plates 41 are fixedly connected with a folding plate 42, and a plurality of equidistantly distributed transverse bars are fixedly connected between the two conveying chains 43, and the gap between two adjacent transverse bars can be used to make the soil turned up with the straw roots leak down and fall back to the ground;

[0055] The impact part is composed of a reciprocating push assembly respectively installed on two folding plates 42. The reciprocating push assembly includes a vertical slot 44 opened on the horizontal plate 41 and a plurality of horizontal slots 45 opened on the folding plate 42. A square column 46 is movably penetrated inside each horizontal slot 45. A push plate 411 is fixedly connected between one end of the plurality of square columns 46 extending to the inner side of the folding plate 42. The number of the horizontal slots 45 and the square columns 46 is described as three for example. The actual number can be adjusted according to the conveying length of the conveying chain 43. A protective piece is installed on the top of the push plate 411.

[0056] The square column 46 corresponding to the vertical slot 44 extends to one end of the outer side of the folding plate 42 and is fixed with a side plate 47. A spring 410 is fixedly connected between the side plate 47 and the corresponding folding plate 42. When the spring 410 is in a natural state, the push plate 411 is pushed to the position as shown in FIG. Figure 6In the state of the left end shown, the square column 46 corresponding to the vertical slot 44 extends to the top of the outer side of the folding plate 42 and is fixed with a rack 49, and the top of the horizontal plate 41 is fixedly installed with a motor 3, and the end of the output shaft of the motor 3 is fixedly sleeved with a half gear 48 corresponding to the vertical slot 44 at the position, and the half gear 48 passes through the vertical slot 44 and meshes with the corresponding rack 49, wherein the two reciprocating push assemblies operate alternately, that is, Figure 6 When the spring 1 410 at the left end is in a natural state, the spring 1 410 at the right end is in a compressed state, so that the straw roots with soil are repeatedly impacted left and right while being transported on the conveyor chain 43, and the soil remaining at the straw roots is knocked down and falls back to the ground;

[0057] The protective member includes ear plates 416 fixed at both ends of the top of the push plate 411 and a baffle 413 fixed at one side of the top of the push plate 411. A movable plate 412 is hingedly installed between the two ear plates 416. A through slot 414 arranged obliquely is provided on one side of the baffle 413. A support bar 415 is fixed inside the through slot 414. Figure 6 As shown, no matter whether the spring 410 on the two reciprocating pushing assemblies is in a natural state or a compressed state, the end of the movable plate 412 away from the corresponding push plate 411 is obliquely overlapped on the inclined section surface of the corresponding fold line plate 42, which can effectively prevent the straw roots with soil that have detached from the arc-shaped flap 36 from falling onto the conveying chain 43. The straw roots fall into the gap between the push plate 411 and the vertical section of the corresponding fold line plate 42, thereby affecting the normal operation of the corresponding reciprocating pushing assembly. In addition, the inclined movable plate 412 can be used in conjunction with the inclined through groove 414 on the baffle bar 413 to guide the scattered soil back to the ground, thereby preventing the scattered soil from accumulating on the upper part of the corresponding square column 46.

[0058] It should be noted that when the arc-shaped flap 36 where the soil with the roots of the straws is detached from falls onto the soil removal and conveying station, if the soil with the roots of the straws falls on the inclined surface of the folding plate 42 or the surface of the inclined movable plate 412, a collision will occur, causing the soil in blocks to be scattered and the soil remaining at the roots of the straws to be separated from the roots of the straws, and then slide to the conveying area between the two push plates 411. If the soil with the roots of the straws falls directly on the conveying area between the two push plates 411, a collision will also occur, causing the soil in blocks to be scattered and the soil remaining at the roots of the straws to be separated from the roots of the straws, and the soil falling into the conveying area between the two push plates 411 will leak from the gap between the two adjacent cross bars and fall back to the ground, and larger soil blocks and the roots of the straws with soil still remaining will be trapped in the conveying area;

[0059] Then, as the conveying chain 43 drives the larger soil blocks trapped in the conveying area and the straw roots that still have soil remaining on them to continue to be conveyed forward, the motors 3 on the two reciprocating pushing assemblies will alternately drive the corresponding half gear 1 48 to rotate, so that when the gear tooth area on the half gear 1 48 is meshed with the corresponding rack 1 49, the rotation of the half gear 1 48 is used to drive the corresponding rack 1 49 to drive the square column to move, so that the corresponding spring 1 410 is compressed to store energy. When the gear tooth area on the half gear 1 48 is completely staggered with the corresponding rack 1 49 (that is, the non-gear tooth area on the half gear 1 48 is directly opposite to the corresponding rack 1 49), the moving square column 46 will be at the corresponding spring 1 Under the action of the restoring force of 410, it is instantly reset, thereby driving the corresponding push plate 411 to be instantly and quickly pushed out, giving an impact force to the larger soil blocks trapped in the conveying area and the straw roots with residual soil, causing them to collide with another push plate 411. In this process, the larger soil blocks will be broken up due to the instantaneous impact force and leak down to the ground. At the same time, the straw roots with residual soil will also be separated from the straw roots due to this instantaneous impact force, and the separated soil will leak down to the ground. This cycle is repeated, and in the process of conveying the straw roots, the residual soil on them can be more completely separated, so that the straw roots without soil can enter the picking and crushing station.

[0060] Specifically, Figure 2 and Figure 9-11 As shown, the picking and crushing mechanism 5 is composed of a picking assembly for gradually lifting the roots of the straw after the soil is removed and a crushing assembly for crushing the roots of the straw after the soil is removed. The picking assembly includes two cylinders 51 fixedly installed on the top of the inner side of the walking frame 1 and a partition 54 fixed between the two sides of the inner cavity of the walking frame 1. A support platform 52 that fits the outer side of the partition 54 is fixedly connected between the telescopic ends of the two cylinders 51. The horizontal plane where the upper end surface of the support platform 52 in the initial state is located is lower than the horizontal plane where the outer upper end surface of the conveying chain 43 is located, so that the roots of the straw without soil can be smoothly transported to the top of the support platform 52. An inclined groove 53 is provided on the top of the support platform 52. The setting of the inclined groove 53 can prevent the roots of the straw without soil that fall on the support platform 52 from detaching from the support platform 52 during the rising process of the support platform 52.

[0061] The crushing assembly includes two side frames 55 fixed on one side of the partition 54, and two squeezing rollers 56 rotating in opposite directions and a conveyor belt 59 located below the squeezing rollers 56 are rotatably installed between the two side frames 55. The two squeezing rollers 56 rotating in opposite directions can be used to pre-flatten the roots of the soilless straw to be crushed, so as to facilitate subsequent slitting. A U-shaped plate 57 corresponding to the squeezing roller 56 is fixedly installed on the outer side of one of the side frames 55, and a motor 4 is fixedly installed on the outer side of the U-shaped plate 57. The output shaft of the motor 4 movably passes through the two side frames 55, and the squeezing roller 56 is fixedly sleeved on the output shaft corresponding to the motor 4.

[0062] Two vertical plates 520 are fixedly arranged between the two side frames 55, and a plurality of straight cutting knives 521 are fixedly arranged at equal intervals between the opposite sides of the two vertical plates 520, and a cylinder 3 518 is fixedly installed on the outer side of one of the vertical plates 520, and an L-shaped cutting knife 519 is fixedly connected to the telescopic end of the cylinder 3 518, wherein the groove formed between the two relatively arranged vertical plates 520 can be used to guide the pre-flattened straw roots to move downward, and in the process of the pre-flattened straw roots moving downward, the plurality of straight cutting knives 521 are used to divide them into a plurality of small strips, and then the cylinder 3 518 is used to drive the L-shaped cutting knife 519 to reciprocate, so as to realize the chopping process of the straw roots divided into a plurality of small strips, and in order to ensure the smooth progress of the chopping process, the length of the vertical plate 520 away from the L-shaped cutting knife 519 needs to be set to be longer than the length of the vertical plate 520 close to the L-shaped cutting knife 519, so that the extra part of the vertical plate 520 can be used as a pad support during the chopping process;

[0063] An auxiliary pressing assembly for pressing the target straw root downward is provided between the two side frames 55, and the auxiliary pressing assembly includes a guide frame 512 fixed between the two side frames 55 and located between the two squeezing rollers 56, and a U-shaped frame 510 movably penetrating between the two guide frames 512. The two guide frames 512 can be used to restrict the U-shaped frame 510 so that the U-shaped frame 510 can only move in the vertical direction. A round rod 516 is fixedly provided at the middle of the inner side of the U-shaped frame 510, and an arc-shaped push strip 517 is fixedly connected to the bottom end of the round rod 516.

[0064] The auxiliary pressing assembly also includes half gears 2 58 fixedly sleeved on both ends of the outer side of the output shaft of the motor 4 and racks 2 511 fixed on the outer sides of both ends of the U-shaped frame 510 and meshing with the corresponding half gears 2 58. The bottom ends of the two side frames 55 on the opposite sides are fixed with base brackets 513 corresponding to the U-shaped frame 510, and the tops of the two base brackets 513 are fixed with vertical rods 514. Both ends of the U-shaped frame 510 are provided with rod grooves that are directly opposite to the corresponding vertical rods 514, and the tops of the vertical rods 514 are movably inserted into the corresponding rod grooves. The outer side of the vertical rod 514 is sleeved with springs 2 515 that are fixedly connected to the corresponding base brackets 513 and the guide frame 512. When the springs 2 515 are in a natural state, the U-shaped frame 510 is in a state as shown in FIG. Fig.10 In the state shown, the arc-shaped push strip 517 in this state will not affect the soilless straw roots entering between the two squeezing rollers 56 as the support platform 52 is lifted, and the top end of the vertical rod 514 remains inserted into the corresponding rod groove.

[0065] It should be noted that, when the soilless straw roots fall to the top of the support platform 52 with the conveyor chain 43, the inclined groove 53 on the top of the support platform 52 will be used to cooperate with the partition 54 to stably support the soilless straw roots, and then the support platform 52 carrying the soilless straw roots will be driven upward by the cylinder 2 51. When the support platform 52 rises to the point where the lower end of the inclined groove 53 is flush with the upper end surface of the partition 54, the soilless straw roots will roll along the inclined groove 53 to between the two squeezing rollers 56 due to the lack of obstruction by the partition 54. In this process, an image sensor can be used to detect whether there are soilless straw roots between the two squeezing rollers 56. If so, the motor 4 is started to drive the corresponding squeezing roller 56 to rotate, otherwise the squeezing roller 56 stops rotating.

[0066] When the motor 4 is started to drive the corresponding squeezing roller 56 to rotate, the half gear 2 58 will rotate synchronously. When the gear area on the half gear 2 58 is meshed with the rack 2 511 on the U-shaped frame 510, the U-shaped frame 510 will move downward with the rotation of the half gear 2 58, and compress the spring 2 515 along the vertical rod 514. At the same time, it drives the arc push bar 517 to move downward synchronously. The arc push bar 517 that gradually moves downward will push the soilless straw roots between the two squeezing rollers 56 to move downward, so that it continues to enter between the two squeezing rollers 56 for pre-flattening treatment, and the pre-flattened straw roots continue to move downward under the drive of the squeezing roller 56 through the area where the straight cutting knife 521 is located, and then are chopped by the reciprocating L-shaped cutting knife 519. The chopped straw roots will fall directly onto the conveyor belt 59 and be transported to the upper layer of the soil after the ridge is broken and turned up along the conveyor belt 59.

[0067] Specifically, Figure 2 and Fig.12 As shown, the stirring and leveling mechanism 6 includes a cylinder four 61 fixed on the top inner side of the walking frame 1 and limiting blocks 62 fixed on both sides of the inner cavity of the walking frame 1, the telescopic end of the cylinder four 61 is fixedly connected to a cover frame 63, and the two sides of the cover frame 63 are in contact with the opposite sides of the two limiting blocks 62 for up and down movement, one end of the cover frame 63 is fixedly connected to a Y-shaped seat 65, and one end of the Y-shaped seat 65 is fixedly connected to a scraper 66. The setting of the Y-shaped seat 65 can effectively improve the stability of the scraper 66 in the process of land leveling, and a motor five is fixedly installed inside the cover frame 63, and the end of the output shaft of the motor five is fixedly connected to a rotating frame 64 located at the bottom of the cover frame 63, wherein the rotating frame 64 is composed of a circular plate and strips evenly distributed in a ring shape on the outside of the circular plate, and a plurality of stirring rods are fixedly provided at the bottom of the circular plate and each strip.

[0068] It should be noted that after the chopped straw roots are transported to the upper layer of the soil after the ridges are broken and turned up by the conveyor belt 59, the cover frame 63 will be pushed downward by the cylinder four 61, thereby driving the bottom end of the stirring rod on the rotating frame 64 to be inserted into the soil, and then the rotating frame 64 will be driven to rotate by the motor five, so as to utilize the stirring rod that rotates accordingly to mix the soil and the chopped straw roots, and if there are larger clods of soil, the rotating stirring rod can also be used to further crush the clods of soil. Then, as the walking frame 1 moves forward, the scraper 66 will be used to level the land containing straw root debris after stirring, so as to achieve the mixing of the crushed straw roots and the soil while completing the leveling of the soil mixed with the straw roots during the movement of the walking frame 1.
