Description
Technical Field
[0001] The invention relates to the technical field of rotary tillers, and in particular to an adaptive rotary tiller and a method for using the same. Background Art
[0002] Cultivating land is the most basic operation in agricultural farming. Its main purpose is to bury the compacted surface soil together with surface weeds, stubble, insect eggs, grass seeds, green manure or manure to the bottom of the ditch through plowing, so as to loosen the soil, improve the structure of the tillage layer, promote the coordination of water, fertilizer, air and heat in the soil, eliminate weeds and pests, improve soil fertility, and create good soil conditions for crop growth and development. Rotary tillers have the characteristics of strong soil crushing ability and flat surface after plowing. At the same time, they can cut the root stubble buried below the surface, which is convenient for the operation of the seed drill and provides a good seed bed for later sowing. Therefore, rotary tillers are widely used to carry out tillage operations on the fields. During the overall advancement of the bracket, the straw and film on the field are easy to rotate with the knife body, so that the straw and film are wrapped around the shaft body, resulting in an increase in the rotation resistance of the shaft body. Summary of the invention
[0003] The object of the present invention is to provide an adaptive rotary tiller and a method of using the same to solve the problems raised in the above-mentioned background technology.
[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an adaptive rotary tiller, comprising: The bracket comprises a front bracket, a rear bracket and a side bracket, the front bracket is movably connected to the rear bracket, and the front bracket and the rear bracket are connected by a first telescopic rod, the side brackets are installed on both sides of the rear bracket, the rear bracket and the side bracket are also connected by a second telescopic rod, and two sets of connecting rods are installed on the lower side of the rear bracket and the front side of the side bracket; The sundry parts are installed on two sets of connecting rods; The knife group is installed on the lower side of the rear bracket and the side bracket, and the knife group is located at the rear side of the debris removal part.
[0005] The front bracket needs to be connected to the tractor, and the movement of the tractor drives the bracket and the debris removal component and the knife group connected to the bracket to move. When the knife group is in the process of plowing the land, the bottom end of the debris removal component contacts the ground, and the straw and film in the field are scraped off, thereby preventing the straw and film from moving to the knife group on the rear side, thereby preventing the straw and film from being entangled on the knife group.
[0006] Furthermore, two first upright seats are installed at the end of the front bracket, and two first angle seats are installed on one side of the rear bracket. The first upright seats and the first angle seats are distributed correspondingly. The front bracket and the rear bracket are connected by the first upright seats and the first angle seats being installed in coordination. A first hinged seat is fixed on the upper surface of the front bracket, and a second hinged seat is installed on the rear bracket; the first hinged seat and the second hinged seat are connected by a first telescopic rod.
[0007] Furthermore, a snap-in groove is provided on both sides of the rear bracket, a snap-in seat is provided on one side of the side bracket, the rear bracket and the side bracket are connected through the snap-in grooves and the corresponding snap-in seats, two second upright seats are provided on the rear bracket, a snap-in seat is provided on the side bracket, and the second upright seats and the snap-in seat are connected through a second telescopic rod.
[0008] Furthermore, the rear bracket is movably connected to the end of the front bracket, and the flipping angle of the rear bracket is changed by contracting or extending the first telescopic rod, so as to change the tillage depth of the blade assembly installed on the rear bracket; In addition, the side bracket can be flipped upward by contracting the second telescopic rod, and the two side brackets can be flipped upward until they are rotated to a vertical state, thereby reducing the width of the bracket, making it easier to pass through narrow roads. In the field, the second telescopic rod can be extended to keep the two side brackets level with the rear bracket, thereby increasing the length of the cultivated land and increasing the cultivated land area within a fixed time.
[0009] Further, side upright plates are provided on opposite sides of the rear bracket, a knife group is installed between the two side upright plates, a motor connected to the knife group is installed on the outer side of any side upright plate, side plates are provided on opposite sides of the side bracket, another knife group is installed between the two side plates, and a motor connected to the other knife group is installed on the outer side plate; Motors can be installed on the outer sides of the side panels and the side panels, which drive the knife groups to rotate and cultivate the land. The knife groups on the rear bracket and the side bracket can be replaced with scraper structures to achieve leveling of the cultivated land.
[0010] Furthermore, the knife group includes a shaft, a knife disc and a knife body, a plurality of knife discs are installed on the shaft, a plurality of knife bodies are installed on the knife disc, a retaining ring is installed on one side of the knife disc, and the retaining ring seals one side of the knife disc.
[0011] Furthermore, a plurality of mounting grooves are provided on the cutter disc, the cross-section of the mounting grooves is similar to a rhombus-shaped surface, a connecting seat is rotatably installed in the mounting groove, one end of the connecting seat extends out of the mounting groove and is connected to the cutter body, a rubber block and a spring are installed in the mounting groove, the rubber block and the spring are respectively located on both sides of the connecting seat, and the rubber block and the spring are symmetrically distributed along the center of the mounting point of the connecting seat; The retaining ring is used for sealing, which effectively prevents mud from entering the installation groove. The mud entering the installation groove causes the rotation of the connecting seat to be blocked. The rubber block is installed on the arc-shaped opening of the installation groove to close the opening on the arc-shaped surface, which effectively prevents mud from entering the installation groove. During the rotation of the cutter body, when the cutter body hits hard soil or stone, the cutter body drives the connecting seat to squeeze the rubber block. The cutter body and the connecting seat are offset by the deformation of the rubber block, which can reduce the impact on the cutter body. The connecting seat is supported by the rubber block and the spring, which effectively solves the problem that when only the rubber block is installed, the rubber block is squeezed for a long time during the operation of the cutter body and causes irreversible deformation, causing the installed connecting seat to shake easily.
[0012] Furthermore, the debris removing part includes a cross bar and a claw body, two first connecting seats are installed on the cross bar, the first connecting seats are connected to the ends of the connecting rod, a plurality of mounting grooves are opened on the outer surface of the cross bar, a plurality of triangular seats are provided on the inner side of the claw body, the triangular seats are deeply inserted into the mounting grooves, and the triangular seats are connected to the pin rods passing through the mounting grooves, and spring sheets are installed between the claw body and the cross bar.
[0013] Furthermore, at least one second connecting seat is provided on the cross bar, a baffle is provided on one side of the cross bar, a plurality of groups of long grooves and open grooves are opened on the baffle, the top end of the claw body passes through the corresponding long groove, the bottom end of the claw body passes through the corresponding open groove, at least one group of vertical frames is provided on the baffle, the vertical frames are distributed corresponding to the second connecting seat, and a vertical seat cooperating with the second connecting seat is provided on the inner side of the vertical frame.
[0014] Furthermore, a column is provided on the inner side of the connecting rod, a third telescopic rod is installed on the column, and a telescopic end of the third telescopic rod is connected to the top end of the stand; During the overall forward movement of the bracket, the bottom end of the claw body is located on the bottom surface, and the rake composed of several claw bodies completes the collection of straw and film on the field, effectively preventing the straw and film from adhering to the shaft body, which causes the rotation resistance of the shaft body to increase. The triangular seat is rotatably installed in the mounting groove, and the claw body is connected to the cross bar by a spring piece. When the bottom end of the claw body encounters a stone or a hard clod, the claw body compresses the spring piece to cause it to deviate, thereby preventing the claw body from bending after colliding with the stone or hard clod. When cleaning the straw and film collected on the rake composed of the claw body, the third telescopic rod is contracted to drive the baffle to rotate forward around the pin shaft on the second connecting seat, pushing the straw and film on the front side of the claw body to separate from the claw body, thereby completing the cleaning of the claw body.
[0015] A method for using an adaptive rotary tiller comprises the following steps: Step 1: The tractor moves to drive the bracket and the debris removal parts and the knife group connected to the bracket to move; Step 2: When the knife group is plowing the land, the bottom end of the debris removal part contacts the ground, scraping off the straw and film in the field, thereby preventing the straw and film from moving toward the knife group at the rear side, thereby preventing the straw and film from being entangled on the knife group.
[0016] The present invention has the following beneficial effects: (1) The bottom end of the debris removal member of the present invention contacts the ground and scrapes off the straw and film in the field, thereby preventing the straw and film from moving toward the rear blade assembly, thereby preventing the straw and film from being entangled on the blade assembly.
[0017] (2) The present invention uses a retaining ring for sealing, which effectively prevents mud from entering the installation groove. Mud that enters the installation groove causes the connection seat to be blocked from rotating. In addition, a rubber block is installed on the arc-shaped opening of the installation groove to close the opening on the arc-shaped surface, effectively preventing mud from entering the installation groove. During the rotation of the cutter body, when the cutter body hits hard mud or stone, the cutter body drives the connection seat to squeeze the rubber block. The rubber block is deformed to achieve the offset of the cutter body and the connection seat, which can reduce the impact on the cutter body.
[0018] (3) In the process of the overall forward movement of the bracket of the present invention, the bottom end of the claw body is located on the bottom surface, and the rake composed of several claw bodies completes the collection of straw and film on the field, effectively preventing the straw and film from adhering to the shaft body, which causes the rotation resistance of the shaft body to increase. The triangular seat is rotatably installed in the installation groove, and the claw body is connected to the cross bar by a spring sheet. When the bottom end of the claw body encounters a stone or a hard clod, the claw body compresses the spring sheet to cause it to deviate, thereby preventing the claw body from bending after colliding with the stone or hard clod. When cleaning the straw and film collected on the rake composed of the claw body, the third telescopic rod is contracted to drive the baffle to rotate forward around the pin shaft on the second connecting seat, pushing the straw and film on the front side of the claw body to separate from the claw body, thereby completing the cleaning of the claw body.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1
[0023] See also Figure 1-Figure 10 As shown, the present invention is an adaptive rotary tiller and a method for using the same, comprising: The bracket comprises a front bracket 1, a rear bracket 2 and a side bracket 3, wherein the front bracket 1 is movably connected to the rear bracket 2, and the front bracket 1 is connected to the rear bracket 2 via a first telescopic rod 4; Side brackets 3 are installed on both sides of the rear bracket 2, and the rear bracket 2 and the side bracket 3 are also connected by a second telescopic rod 5; Two sets of connecting rods 9 are installed on the lower side of the rear bracket 2 and the front side of the side bracket 3; Two first upright seats 101 are installed at the end of the front bracket 1, and two first corner seats 201 are installed on one side of the rear bracket 2. The first upright seats 101 and the first corner seats 201 are distributed correspondingly. The front bracket 1 and the rear bracket 2 are connected by the first upright seats 101 and the first corner seats 201 being installed in coordination. A first hinged seat 102 is fixed on the upper surface of the front bracket 1, and a second hinged seat 204 is installed on the rear bracket 2; the first hinged seat 102 and the second hinged seat 204 are connected by a first telescopic rod 4.
[0024] A snap-in groove 202 is provided on both sides of the rear bracket 2, and a snap-in seat 301 is provided on one side of the side bracket 3. The rear bracket 2 and the side bracket 3 are connected by the snap-in groove 202 and the corresponding snap-in seat 301. Two second upright seats 203 are provided on the rear bracket 2, and a snap-in seat 301 is provided on the side bracket 3. The second upright seats 203 and the snap-in seat 301 are connected by a second telescopic rod 5.
[0025] The end of the front bracket 1 is movably connected to the rear bracket 2, and the first telescopic rod 4 is contracted or extended to change the flipping angle of the rear bracket 2, so as to change the tillage depth of the blade group 8 installed on the rear bracket 2, and perform adaptive adjustment according to the conditions of the land; In addition, the side bracket 3 can be flipped upward by contracting the second telescopic rod 5, and the two side brackets 3 can be flipped upward until they are rotated to a vertical state, thereby reducing the width of the bracket, making it easier to pass through narrow roads. In the field, the second telescopic rod 5 can be extended to keep the two side brackets 3 level with the rear bracket 2, thereby increasing the length of the cultivated land and increasing the cultivated land area within a fixed time.
[0026] like Figure 5-Figure 6 As shown, the debris removal component 7 is installed on two sets of connecting rods 9; The debris removing part 7 includes a cross bar 701 and a claw body 702. Two first connecting seats 7011 are installed on the cross bar 701. The first connecting seats 7011 are connected to the end of the connecting rod 9. A plurality of mounting grooves 7013 are provided on the outer surface of the cross bar 701. A plurality of triangular seats 7021 are provided on the inner side of the claw body 702. The triangular seats 7021 are deeply inserted into the mounting grooves 7013. At the same time, the triangular seats 7021 are connected to the pin rod 703 passing through the mounting grooves 7013. A spring piece 704 is installed between the claw body 702 and the cross bar 701.
[0027] At least one second connecting seat 7012 is provided on the cross bar 701, a baffle 705 is provided on one side of the cross bar 701, a plurality of groups of long grooves 7051 and open grooves 7052 are provided on the baffle 705, the top end of the claw body 702 passes through the corresponding long groove 7051, the bottom end of the claw body 702 passes through the corresponding open groove 7052, at least one group of vertical frames 706 is provided on the baffle 705, the vertical frames 706 are distributed corresponding to the second connecting seat 7012, and a vertical seat matching the second connecting seat 7012 is provided on the inner side of the vertical frames 706.
[0028] The bottom end of the claw body 702 is a curved rod body, which is bent toward one side of the front bracket 1. When the bracket is moving, the bottom end of the claw body 702 is inserted into the ground and slides on the ground. The sliding claw body 702 scrapes up the film on the ground. As the claw body 702 continues to move forward, the scraped film adheres to a number of claw bodies 702 distributed in a row. The film on the bottom surface of the land to be cultivated is removed by the claw body 702 to prevent the film from being entangled on the shaft of the knife group 8 during rotary tillage. The entangled film will increase the rotational resistance of the knife group 8.
[0029] A column is provided on the inner side of the connecting rod 9 , and a third telescopic rod is installed on the column. The telescopic end of the third telescopic rod is connected to the top end of the stand 706 .
[0030] As the attached film increases, the film slides upward along the claw body 702, and the baffle 705 prevents the film from continuing to move. When cleaning, the third telescopic rod installed on the connecting rod 9 shrinks until the claw body 702 contacts the lower arc-shaped inner wall of the long groove 7051. At this time, the lower edge of the baffle 705 is located at the front side of the bottom end of the claw body 702, thereby driving the stand 706 and the baffle 705 to rotate around the stand, and the rotating baffle 705 rotates toward the front side of the claw body 702, pushing the film on the claw body 702 to separate from the claw body 702, so that the film is separated from the claw body 702; During the process of the baffle 705 being reset, the third telescopic rod is extended until the claw body 702 contacts the arc-shaped inner wall of the opening groove 7052. During the process of the baffle 705 being moved, the claw body 702 is always located in the long groove 7051. During the overall forward movement of the bracket, the bottom end of the claw body 702 is located on the bottom surface, and a plurality of claw bodies 702 form a rake to collect the straw and film on the field, effectively preventing the straw and film from adhering to the shaft body 801, thereby increasing the rotation resistance of the shaft body 801; The triangular seat 7021 is rotatably installed in the installation groove 7013, and the claw body 702 is connected to the cross bar 701 through the spring sheet 704. When the bottom end of the claw body 702 encounters a stone or a hard soil block, the claw body 702 compresses the spring sheet 704 to deflect, thereby preventing the claw body 702 from bending after colliding with the stone or hard soil block. When cleaning the straw and film collected on the rake formed by the claw body 702, the third telescopic rod is contracted to drive the baffle 705 to rotate forward around the pin shaft on the second connecting seat 7012, pushing the straw and film on the front side of the claw body 702 away from the claw body 702, thereby completing the cleaning of the claw body 702.
[0031] like Figure 7-10 As shown, the knife group 8 is installed on the lower side of the rear bracket 2 and the side bracket 3, and the knife group 8 is located on the rear side of the debris removing component 7.
[0032] The knife group 8 includes a shaft 801, a knife disc 802 and a knife body 803. Several groups of knife discs 802 are installed on the shaft 801. Several knife bodies 803 are installed on the knife disc 802. A retaining ring is installed on one side of the knife disc 802 to seal one side of the knife disc 802.
[0033] A plurality of mounting grooves 8021 are provided on the cutter disc 802, and the cross-sectional surface of the mounting groove 8021 is similar to a rhombus surface. A connecting seat 804 is rotatably installed in the mounting groove 8021, and one end of the connecting seat 804 extends out of the mounting groove 8021 and is connected to the cutter body 803. A rubber block 805 and a spring 806 are installed in the mounting groove 8021, and the rubber block 805 and the spring 806 are respectively located on both sides of the connecting seat 804, and at the same time, the rubber block 805 and the spring 806 are symmetrically distributed along the center of the mounting point of the connecting seat 804.
[0034] The retaining ring is used for sealing, which effectively prevents dirt from entering the installation groove 7013. The dirt entering the installation groove 7013 will hinder the rotation of the connecting seat 804. In addition, the rubber block 805 is installed on the arc surface opening of the installation groove 7013 to achieve the sealing of the arc surface opening, effectively preventing mud from entering the installation groove 7013. When the blade body 803 hits hard mud or stone during the rotation of the blade body 803, the blade body 803 drives the connecting seat 804 to squeeze the rubber block 805. The deformation of the rubber block 805 can realize the offset of the blade body 803 and the connecting seat 804, which can reduce the impact on the blade body 803. In addition, the connecting seat 804 is supported by the rubber block 805 and the spring 806, which effectively solves the problem that when only the rubber block 805 is installed, the rubber block 805 is squeezed for a long time and irreversibly deformed during the operation of the knife body 803, causing the installed connecting seat 804 to shake easily.
[0035] When in use, the front bracket 1 needs to be connected to the tractor; The movement of the tractor drives the bracket and the debris removal component 7 and the knife group 8 connected to the bracket to move. When the knife group 8 is in the process of plowing the land, the bottom end of the debris removal component 7 contacts the ground, and the straw and film in the field are scraped off, thereby preventing the straw and film from moving to the rear side of the knife group 8, thereby preventing the straw and film from being entangled on the knife group 8.
[0036] Side upright plates 205 are provided on opposite sides of the rear bracket 2, a knife group 8 is installed between the two side upright plates 205, a motor 6 connected to the knife group 8 is installed on the outer side of any side upright plate 205, side panels 303 are provided on opposite sides of the side bracket 3, another knife group 8 is installed between the two side panels 303, and a motor 6 connected to the other knife group 8 is installed on the outer side panel 303.
[0037] The outer sides of the side upright plate 205 and the side plate 303 can be installed with a motor 6, and the motor 6 drives the knife group 8 to rotate, and the rotating knife group 8 is used to cultivate the land; In addition, the blade groups 8 on the rear support 2 and the side support 3 can be replaced and can be replaced with a scraper structure to achieve a leveling process for the cultivated field. Example 2
[0038] A method for using an adaptive rotary tiller comprises the following steps: Step 1: The tractor moves the bracket and the debris removal component 7 and the knife group 8 connected to the bracket; Step 2: When the knife group 8 is in the process of tilling the land, the bottom end of the debris removal component 7 contacts the ground, scraping off the straw and film in the field, thereby preventing the straw and film from moving toward the knife group 8 on the rear side, thereby preventing the straw and film from being entangled on the knife group 8.
[0039] The movement of the tractor drives the bracket and the debris removal component 7 and the knife group 8 connected to the bracket to move. When the knife group 8 is in the process of plowing the land, the bottom end of the debris removal component 7 contacts the ground, and the straw and film in the field are scraped off, thereby preventing the straw and film from moving to the rear side of the knife group 8, thereby preventing the straw and film from being entangled on the knife group 8.
