At least two double-row rotary tillage operations are required to ensure the thoroughness of rotary tillage and crushing; in the process of fertilization, in order to achieve the purpose of accurate waste into the ridge, the existing structure uses a discharge channel with a switch gate to release the waste. During the process of fertilizer diversion and falling in the pipeline, granular fertilizer is prone to pipe blockage, resulting in interruption of fertilization, resulting in a lack of fertilizer in a certain distance of the ridge, that is, fertilization interruption.

[0007] During the rotary tillage and fertilization process, the rotary tillage operation of the rotary tillage device is performed in front, and the vibration fertilizer application device releases the fertilizer afterwards, thereby achieving rotary tillage before fertilization; during the rotary tillage process, the rotary tillage shaft of the rotary tillage blade has an axial displacement, and the rotary tillage blade moves back and forth following the axial displacement of the rotary tillage shaft, and the sand is transversely tilled by the transverse tillage protrusions arranged on the side of the rotary tillage blade; during the vibration fertilizer release process, the furrow opener, the vibrating fertilizer pipe and the soil coverer of the vibrating fertilizer application device are arranged in sequence from front to back, the furrow opener pushes sand to form a furrow, the vibrating fertilizer pipe vibrates to release the fertilizer accurately into the furrow, and the soil coverer pushes sand to fill the furrow and cover the fertilizer.

[0008] Furthermore, during transverse tillage, the transverse tillage protrusions cut and crush the sand blocks through the cutting edges formed at the ends of the protrusions in the extending direction; the transverse tillage protrusions are distributed on both sides of the rotary tillage blade to form a double-sided transverse cutting structure.

[0009] Furthermore, during the rotary tillage process, the rotary tillage operation of the rotary tilling blade is the main operation, and the transverse tillage operation of the transverse tillage protrusion is the auxiliary operation, and during transverse tillage, the limit travel range of the axial displacement of the rotary tillage shaft is between half the blade pitch and one blade pitch of the rotary tillage blade.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] As attached Figure 1As shown, a rotary tillage and fertilization method of a sandy land rotary tillage and fertilization integrated system includes a rotary tillage and fertilization integrated system, and a rotary tillage and fertilization method for rotary tillage and fertilization of sandy land using the rotary tillage and fertilization integrated system; includes a rotary tillage device 2 arranged on a rubber track vehicle 1, and the rubber track vehicle 1 rotary tillages the sandy land through the rotary tillage curved blade 24 of the rotary tillage device 2 during the moving process; includes a vibrating fertilization device 3 arranged on the rubber track vehicle 1, and the rubber track vehicle 1 releases fertilizer through the vibration of the vibrating fertilization device 3 during the moving process; in the rotary tillage and fertilization process, the rotary tillage operation of the rotary tillage device 2 is performed first, and the vibration release of the fertilizer by the vibrating fertilization device 3 is performed later, so as to realize rotary tillage first and then fertilization.

[0029] The double-row rotary tillage structure is limited by structural and cost factors. In the actual tillage operation process, some blocks are still missed and not broken. At least two double-row rotary tillage operations are required to ensure the thoroughness of rotary tillage and crushing, but it affects the tillage efficiency. In order to solve the above problems, in the present invention, as shown in the attached Figure 2 and 3 As shown, during the rotary tillage process, the rotary tillage shaft 23 of the rotary tillage blade 24 has an axial displacement, and the rotary tillage blade 24 moves back and forth following the axial displacement of the rotary tillage shaft 23. The sand is transversely tilled by the transverse tillage protrusion 2.4 arranged on the side of the rotary tillage blade 24, so that the blocks missed by the rotary tillage are broken, the efficiency of breaking the cultivated land blocks is improved, and the effective combination of rotary tillage and transverse tillage is achieved to break the cultivated land blocks thoroughly and efficiently. More specifically, during transverse tillage, the transverse tillage protrusion 2.4 cuts and breaks the sand blocks through the cutting edge 2.40 formed at the end of the protrusion extension direction. The cutting edge 2.40 can achieve a transverse cutting effect on the sand blocks, so that the sand blocks are broken more easily and quickly, and the purpose of efficient block breaking is achieved. The transverse tillage protrusion 2.4 is distributed on both sides of the rotary tillage blade 24, forming a bilateral transverse cutting structure, and the transverse tillage cutting can be performed when moving back and forth, further improving the efficiency. It should be noted that during the rotary tillage process, the rotary tillage operation of the rotary tiller blade 24 is the main one, that is, the rotary tillage blade 24 plays the main role in tilling the land, and the transverse tillage operation of the transverse tillage protrusion 2.4 is auxiliary. The transverse tillage protrusion 2.4 plays the role of cutting and crushing the sand blocks that are not completely broken. Therefore, the transverse movement distance cannot be too large so as not to affect the main tillage effect of the rotary tiller blade 24, and during transverse tillage, the limit travel range of the axial displacement of the rotary tillage shaft 23 is between half the blade pitch and one blade pitch of the rotary tiller blade 24, so that during the back-and-forth transverse movement process, the transverse tillage protrusion 2.4 can cover completely without omission, and will not affect the main tillage effect of the rotary tiller blade 24.

[0030] The rotary tilling blades 24 are arranged on the rotary tilling shaft 23 to form a rotary tilling blade row 2.1 rotatably mounted in the bin of the rotary tilling frame 2.2. The rotary tilling blade row 2.1 is composed of two groups arranged side by side in the front and rear directions of the rotary tilling, forming a double-row rotary tilling structure. Correspondingly, the number of the transverse tilling protrusions 2.4 will also increase, thereby improving the efficiency of rotary tilling and transverse tilling.

[0031] The rotary tillage shaft 23 is composed of a shaft body 23a with a rotary tillage blade 24 and a shaft end 23b rotatably connected to the rotary tillage frame 2.2. The shaft body 23a is elastically axially movable relative to the shaft end 23b through an elastic component 26; the shaft end of the shaft body 23a is provided with an axial shift driving component 25; the axial shift driving component 25 drives the shaft body 23a to move axially back and forth, so as to drive the transverse tillage protrusion 2.4 to move back and forth to realize transverse tillage. The elastic component 26 is specifically selected from a spring with a simple structure and low cost, which has a buffering effect.

[0032] In order to ensure that the shaft body 23a can only move axially relative to the shaft end 23b, but cannot rotate relative to the shaft end 23b, so as to ensure the feasibility of rotary tillage, a circumferential limiting component is provided at the connection between the shaft body 23a and the shaft end 23b, and the shaft body 23a and the shaft end 23b are kept circumferentially limited by the circumferential limiting component. The circumferential limiting component is composed of a limiting groove 23.1 and a limiting rod 23.2 axially slidingly embedded in the limiting groove 23.1, and the cross-sectional shapes of the limiting groove 23.1 and the limiting rod 23.2 are both regular polygons, so that circumferential limiting can be achieved. A spring sleeve is arranged on the rod of the limiting rod 23.2 between the shaft body 23a and the shaft end 23b. The shaft end of the shaft body 23a is installed with a radial extension plate 27, that is, an annular plate sleeved on the shaft end of the shaft body 23a. The shaft end of the shaft body 23a has a flange, and the annular plate is coaxially connected to the flange. The number of the shaft shift drive component 25 is one, and the shaft shift drive component 25 is a transverse vibration motor. The vibration end of the transverse vibration motor is horizontally arranged toward the corresponding radial extension plate 27. When the land is broken, the transverse vibration motor vibrates once, and under the action of the elastic force provided by the matching spring, the shaft body 23a axially vibrates and moves back and forth, thereby achieving the purpose of transverse tillage and breaking blocks by axial back and forth movement. After all, the radial extension plate 27 rotates with the shaft body 23a. In order to reduce the contact friction and increase the service life of the equipment, the vibration end of the transverse vibration motor is connected with a rod body 21, and the plate surface of the corresponding radial extension plate 27 is correspondingly provided with a circular slide rail 20, and the rod body 21 is connected to the slider 28 on the circular slide rail 20.

[0033] In order to achieve the purpose of accurate waste delivery to the ridge during fertilization, the existing structure uses a discharge channel in conjunction with a switch gate to release the waste. During the process of fertilizer diversion and falling in the pipeline, granular fertilizer is prone to get stuck in the pipe, resulting in interruption of fertilization and lack of fertilizer in a certain distance of the ridge, that is, interruption of fertilization. In order to solve the above problem, in the present invention, as shown in the attached Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, in the process of releasing fertilizer by vibration, the furrow opener 30, the vibrating fertilizer pipe 31 and the soil cover 32 of the vibrating fertilizing device 3 are arranged from front to back in sequence, the furrow opener 30 pushes sand to form a furrow, the vibrating fertilizer pipe 31 releases fertilizer accurately into the furrow by vibration, and the soil cover 32 pushes sand to fill the furrow and cover the fertilizer. In addition, in the process of releasing fertilizer by vibration, the vibrating fertilizer pipe 31 is supported by the elastic walking mechanism 33, and the elastic walking mechanism 33 walks in the sand ditch. During the walking process, it elastically vibrates up and down with the unevenness of the bottom of the sand ditch, thereby driving the vibrating fertilizer pipe 31 connected to the fertilizer box 3.1 to vibrate and release fertilizer, so as to promote fertilization by vibration, avoid fertilizer pipe blockage, improve the smoothness of fertilizer release, and ensure uninterrupted fertilization. Moreover, the source of vibration power is the rubber crawler 1, and no additional vibration drive is required, which reduces costs; after accurate fertilization into the ditch, it is covered to prevent the fertilizer from being exposed to the outside and volatilizing.

[0034] The elastic walking mechanism 33 includes a guide column 333, a support spring 334 and a roller 330; a support plate 332 is provided on the sliding sleeve of the guide column, and the vibrating fertilization pipe 31 is fixedly connected to the support plate 332; the top of the guide column 333 has a top fixing block connected to the mounting plate 335, the mounting plate 335 is fixedly installed with the fertilizer box 3.1, and the bottom thread of the guide column 333 is screwed with an internal thread cover 336. Two support springs 334 are sleeved on one guide column 333, one of which is elastically arranged between the top fixing block and the support plate 332, and the other is elastically arranged between the support plate 332 and the internal thread cover 336; the roller 330 is connected to the support plate 332 through a matching roller bracket 331.

[0035] The vibration action can not only promote the smooth flow of the granular waste in the vibrating fertilizer pipe 31, but also promote the waste to enter the vibrating fertilizer pipe 31. Specifically, the vibrating fertilizer pipe 31 is movably connected to the discharge port of the fertilizer box 3.1. During the process of releasing the fertilizer by vibration, the vibrating fertilizer pipe 31 pushes the fertilizer vertically through the vibration action of the vibrating fertilizer pipe 31, thereby promoting the fertilizer in the fertilizer box 3.1 to be discharged into the vibrating fertilizer pipe 31. More specifically, the feed end of the vibrating fertilizer pipe 31 is swollen and connected with a deformable connecting piece 34. The fertilizing pipe 31 is movably connected to the discharge port of the fertilizer box 3.1 through the deformable connecting piece 34. The deformable connecting piece 34 is a flexible pipe structure or an axially telescopic pipe structure.

[0036] It is worth noting that in order to prevent debris from entering the discharge port of the vibrating fertilizing pipe 31 and affecting the release of fertilizer, it is necessary to improve the direction of the discharge port of the vibrating fertilizing pipe 31. Specifically, the discharge end of the vibrating fertilizing pipe 31 is bent downward at an angle, and the bending direction is opposite to the travel direction of the rubber crawler vehicle 1.

[0037] The furrow opener 30 is relatively fixedly installed on the fertilizer box 3.1, and the furrow opener 30 corresponds to the vibrating fertilizer pipe 31 one by one, and the furrow opener 30 and the vibrating fertilizer pipe 31 remain independent of each other; the height of the vibration downward limit stroke of the vibrating fertilizer pipe 31 is higher than the bottom of the furrow opener 30, so as to prevent the vibrating fertilizer pipe 31 from touching the sand during the process of releasing fertilizer by vibration. The soil cover 32 is a roller body connected to the fertilizer box 3.1, and the roller body is horizontally arranged in the length direction of the fertilizer box 3.1, so that the roller body covers all the sand trenches in the axial direction, and the soil covering operation of a row of sand trenches is realized by the roller body.

[0038] The present invention combines the thorough tillage of a rotary tillage device with the smooth and uninterrupted fertilization of a vibration fertilization device, thereby improving the efficiency of the integrated tillage and fertilization operation.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
