The three ports of the electrically controlled three-way valve are respectively connected to the solid fertilizer tank, the liquid fertilizer tank and the input end of the solid-liquid pump. The output end of the solid-liquid pump is connected to three parallel telescopic nozzles. The ends of the three telescopic nozzles away from the solid-liquid pump are all connected to nozzles. The central telescopic nozzle is fixedly connected to the nozzles on both sides, and the telescopic nozzles on both sides are rotatably connected to the linkage assembly.

[0009] As a preferred technical solution of the present invention, a rubber elastic band is installed on the fixed rod of the telescopic nozzle, and two switches are installed on the telescopic rod of the telescopic nozzle. The rubber elastic band and the two switches are located on the same axis.

[0010] As a preferred technical solution of the present invention, the side tillage frame includes a connecting frame beam and a support plate, and a plurality of connecting plates are installed on the support plate, and the sides of the plurality of connecting plates away from the support plate are fixedly connected to the two sides of the connecting frame beam in sequence;

[0011] Wherein, a plurality of plowshares are installed on the bottom of the support plate, and the connecting beam is rotatably connected to the linkage assembly.

[0012] As a preferred technical solution of the present invention, the linkage assembly includes four support cylinders, the two rear support cylinders are fixedly connected to the main support beam, the tops of the four support cylinders are rotatably connected to threaded cylinders, the two rear threaded cylinders are threadedly connected to second screws, the bottom ends of the two second screws are fixedly installed with connecting blocks, the two connecting blocks are rotatably connected to the side tillage frame on one side away from the second screw, the two front threaded cylinders are threadedly connected to the first screw, and the bottoms of the two first screws are rotatably connected to the fertilization assembly.

[0013] As a preferred technical solution of the present invention, two servo motors are arranged between the two first screws, and pulleys are installed on the output shafts of the two servo motors and the four threaded cylinders. A first transmission belt is connected between the pulleys on the two servo motors and the pulleys on the adjacent first screws, and a second transmission belt is connected between the pulleys on the two servo motors and the pulleys on the adjacent second screws.

[0014] As a preferred technical solution of the present invention, the connecting block is rotatably connected to the adjacent connecting frame beam, and the rotation angle of the connecting frame beam is ninety degrees upward, and the connecting frame beam cannot rotate downward.

[0015] As a preferred technical solution of the present invention, the length of the two first screws is twice the height of the support cylinder.

[0016] An improved mowing method suitable for hilly grasslands includes the following steps:

[0017] S1. Pre-install the side tillage racks on both sides of the linkage assembly. Adjust the multiple telescopic nozzles to the highest position, so that the telescopic nozzles are extended to their longest position and the rubber elastic bands are not in contact with the two switches. Fill the solid fertilizer tank with solid fertilizer and the liquid fertilizer tank with liquid fertilizer, respectively. Check the status of the drive vehicle's engine, fill the drive vehicle's fuel tank, and then start the drive vehicle and move it to the hilly area where the work is required.

[0018] S2, rotating the servo motor, under the action of the first screw and the adjacent threaded barrel, drives the multiple telescopic nozzles to rotate downward. During the rotation, the telescopic ends of the telescopic nozzles are compressed until the rubber elastic band toggles the first switch, at which time the solid-liquid pump is turned on. The initial state of the electronically controlled three-way valve is that the liquid fertilizer tank, the electronically controlled three-way valve, and the solid-liquid pump are connected, that is, liquid fertilizer is sprayed into the air;

[0019] S3: Continue to start the servo motor and lower it until the telescopic nozzle is compressed to the shortest position it can be shortened to. At this time, the rubber elastic band continues to toggle the second switch, and the electric three-way valve rotates. At this time, the liquid fertilizer tank and the solid fertilizer tank are connected to the solid-liquid pump through the electric three-way valve, that is, the solid-liquid mixed fertilizer is sprayed on the ground. At this time, the coulter partially extends into the soil to perform the plowing operation;

[0020] S4, continue to start the servo motor, driving the telescopic nozzle to extend. At this time, the rubber elastic belt pulls back the switch at the rear to form a solid fertilizer box, and the electronically controlled three-way valve, i.e., the solid-liquid pump, supplies solid fertilizer to the telescopic nozzle. In other words, solid fertilizer is sprayed on the ground and the plowed land. At this time, the coulter is basically fully inserted into the soil for deep plowing operation.

[0021] S5, start the servo motor to rotate in the reverse direction, which will shorten the telescopic nozzle. Turn the switch at the rear to adjust the electric three-way valve back to the state of S3. Continue to start the servo motor in the reverse direction, that is, after S2, it will finally return to the initial state of S1. When the telescopic nozzle returns to the initial state of the support tube, the electric three-way valve will also be restored, and the side tillage frame will not contact the ground.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The device can spray liquid fertilizer at high altitude, solid-liquid mixed fertilizer in the middle, and solid fertilizer at the bottom according to needs. The spraying height, corresponding spraying type, and spraying effect can be adjusted as needed. When there is no need to spray fertilizer, spraying can be stopped directly to prevent waste.

[0024] 2. The device uses the up and down rotation of the telescopic nozzle in the support tube to bring about reciprocating telescopic coordination switch, rubber elastic band linkage semi-automatic control of the electric three-way valve, and telescopic nozzle. In this way, the staff only needs to control the rotation of the servo motor to control the spraying angle, spraying content and spraying direction of the telescopic nozzle.

[0025] 3. While the servo motor rotates to control the telescopic nozzle, the device can also drive the side tillage frame to rise or fall. That is, when there are large rocks or large slopes in front, when the fertilization component is retracted to the maximum height, the side tillage frame will also be retracted to the maximum height. This not only protects the fertilization component, but also has a linkage protection effect on the side tillage frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are all conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0036] Example:

[0037] Example 1,

[0038] like Figure 1 - Figure 8 As shown, a fertilizing device suitable for hilly grasslands includes a driving vehicle 1, a main support beam 2, a fertilizing assembly 3, and a side tillage frame 4. One side of the main support beam 2 is fixedly connected to the front end of the driving vehicle 1, and the other side of the main support beam 2 is hinged to the fertilizing assembly 3. There are two sets of side tillage frames 4, and the two sets of side tillage frames 4 are arranged on both sides of the driving vehicle 1.

[0039] Among them, a linkage component 5 is installed on the main support beam 2, and the fertilizing component 3 is linked to the side tillage frame 4 through the linkage component 5 to adjust the working angle, fertilizing height and avoidance range.

[0040] Auxiliary support beams 11 are installed on both sides of the driving vehicle 1 , and the other ends of the auxiliary support beams 11 are fixedly connected to the main support beam 2 .

[0041] In summary, the device as a whole adopts the fertilizing component 3, the side tillage frame 4, that is, the linkage component 5 on the main support beam 2 to form a whole that can spray fertilizer. The side can cooperate with the surrounding land to turn over in advance to form a linkage effect of spraying and turning over the land. The device cooperates with the driving vehicle 1 body to strengthen the connection between the driving vehicle 1 and the main support beam 2, and balances the overall center of gravity of the driving vehicle 1 after being connected to the device.

[0042] Furthermore, the driving vehicle 1 can be a mountain vehicle, and the overall mass should be greater than twice the combined mass of the main support beam 2, the fertilizer assembly 3 and the linkage assembly 5, so that the center of gravity can be balanced in hilly areas to prevent rollover.

[0043] The fertilization assembly 3 includes a solid fertilizer tank 31, a liquid fertilizer tank 32, an electrically controlled three-way valve 33 and a solid-liquid pump 34. The three ports of the electrically controlled three-way valve 33 are respectively connected to the solid fertilizer tank 31, the liquid fertilizer tank 32 and the input ends of the solid-liquid pump 34. The output end of the solid-liquid pump 34 is connected to three parallel telescopic nozzles 35. The ends of the three telescopic nozzles 35 away from the solid-liquid pump 34 are all connected to a nozzle 38. The central telescopic nozzle 35 is fixedly connected to the nozzles 38 on both sides, and the telescopic nozzles 35 on both sides are rotatably connected to the linkage assembly 5.

[0044] A rubber elastic band 37 is installed on the fixed rod of the telescopic nozzle 35, and two switches 36 are installed on the telescopic rod of the telescopic nozzle 35. The rubber elastic band 37 and the two switches 36 are located on the same axis.

[0045] In summary, the function of the fertilizing component 3 is to provide a fertilizer spraying effect, and in the process of the fertilizing component 3 and the linkage component 5 cooperating in rotation, the fertilizing component 3 can passively retract to adjust the connection direction of the electric three-way valve 33 and the opening and closing of the solid-liquid pump 34. In this way, the rotation of the servo motor 59 can not only drive the telescopic nozzle 35 to rotate and adjust the spraying direction, but also can cooperate with the fertilizing component 3 to adjust the spraying content and the opening and closing of the fertilizing component 3 itself.

[0046] Furthermore, the connection between the electrically controlled three-way valve 33, the solid-liquid pump 34, and the switch 36 can be achieved through electrical connection or signal connection, and the energy supply of the electrically controlled three-way valve 33, the solid-liquid pump 34, and the switch 36 is connected to the energy supply terminal of the driving vehicle 1 by wires.

[0047] Furthermore, the telescopic end and the fixed end of the telescopic nozzle 35 are slidably connected, and a sealing rubber ring is provided at the connection portion to prevent fertilizer from overflowing from the connection portion.

[0048] The side tillage frame 4 includes a connecting frame beam 41 and a support plate 43. A plurality of connecting plates 42 are mounted on the support plate 43. The sides of the plurality of connecting plates 42 away from the support plate 43 are fixedly connected to both sides of the connecting frame beam 41 in sequence.

[0049] Among them, a plurality of plowshares 44 are installed at the bottom of the support plate 43, and the connecting beam 41 is rotatably connected to the linkage assembly 5.

[0050] In summary, the addition of the side tillage frame 4 allows the fertilizing assembly 3 to release and spray fertilizer while the side tillage frame 4 on both sides of the driving vehicle 1 can also plow the land on the hilly surface as needed to achieve the effect of fertilizing part of the soil. The connecting frame beam 41 cooperates with the connecting plate 42 and the support plate 43 to fix multiple plows 44, which can maximize the reduction of the overall plowing weight and will not damage the deep soil. Only shallow plowing of the surface of the land is required to achieve a depth sufficient for fertilization.

[0051] Furthermore, the connection between the side tillage frame 4 and the fertilizing assembly 3 utilizes the linkage assembly 5 to generate linkage control of the fertilizing assembly 3 and the side tillage frame 4, but the linkage assembly 5 is improved to separate control of the side tillage frame 4 and the fertilizing assembly 3, and the control structure becomes more, but the plowing depth of the side tillage frame 4 can be adjusted as needed.

[0052] The linkage assembly 5 includes four support tubes 51, the two rear support tubes 51 are fixedly connected to the main support beam 2, the tops of the four support tubes 51 are rotatably connected to the threaded tubes 52, the two rear threaded tubes 52 are threadedly connected to the second screw rods 57, and the bottom ends of the two second screw rods 57 are fixedly installed with connecting blocks 58, and the two connecting blocks 58 are rotatably connected to the side tillage frame 4 away from the side of the second screw rod 57.

[0053] Two servo motors 59 are installed between the two first screws 56. Pulleys 53 are installed on the output shafts of the two servo motors 59 and the four threaded cylinders 52. A first transmission belt 54 is connected between the pulleys 53 on the two servo motors 59 and the pulleys 53 on the adjacent first screws 56, and a second transmission belt 55 is connected between the pulleys 53 on the two servo motors 59 and the pulleys 53 on the adjacent second screws 57.

[0054] The connecting block 58 is rotatably connected to the adjacent connecting beam 41 , and the rotation angle of the connecting beam 41 is upward 90 degrees, and the connecting beam 41 cannot rotate downward.

[0055] The length of the two first screw rods 56 is twice the height of the support tube 51 .

[0056] In summary, the linkage assembly 5 is the core structure of the device. By starting the servo motor 59, the spraying direction of the fertilizing assembly 3 and the lifting and lowering of the side tillage frame 4 can be adjusted through other components in the linkage assembly 5. When the servo motor 59 is started, the pulley 53 connected to the servo motor 59 is driven to start. The pulley 53 on the top of the servo motor 59 will be connected to the second transmission belt 55 and the first transmission belt 54. One of the second transmission belts 55 is connected to the threaded barrel 52 equipped with the second screw 57, and one of the first transmission belts 54 is connected to the threaded barrel 52 equipped with the first screw 56. That is, the start of the servo motor 59 can drive multiple threaded barrels 52 to rotate. The bottom of the two first screws 56 is rotatably connected to the telescopic nozzle 35, but this rotation connection is limited to the telescopic nozzle 35. The rotation of clockwise and counterclockwise, and the two first screws 56 cannot rotate along the thread direction after being connected to the telescopic nozzle 35. , therefore, when the threaded barrel 52 rotates, the first screw 56 will drive the telescopic nozzle 35 to rise or fall, and the part where the first screw 56 is connected to the telescopic nozzle 35 is the fixed end of the telescopic nozzle 35. Therefore, when the telescopic nozzle 35 rotates, it is originally a circular motion. However, under the limitation of the support barrel 51 and the first screw 56, the telescopic nozzle 35 can only rotate at one end and move up and down at the other end. In this way, when the fixed end of the telescopic nozzle 35 descends, it will gradually compress the telescopic end of the telescopic nozzle 35, that is, without forming a motion limit, the rubber elastic band 37 can also move to toggle the two switches 36 to form the mechanical linkage control effect of the above-mentioned fertilizing assembly 3. Similar to the above principle, under the limitation of the connecting block 58 and the support barrel 51, the second screw 57 cannot rotate either. Therefore, in the process of being connected to the second screw 57, the side tillage frame 4 can be driven to move up and down to avoid large slopes and stones that cannot be crossed by itself.

[0057] Furthermore, a rotational connection is adopted between the connecting frame beam 41 and the connecting block 58. This arrangement allows partial movement on bumpy roads in hilly areas. Compared with a fixed connection, it is less likely to damage the connecting part between the connecting frame beam 41 and the connecting block 58. When encountering a steep slope, the entire side tillage frame 4 can be rotated by itself with the assistance of gravity without directly hitting the slope, which plays a certain protective role for the side tillage frame 4.

[0058] Example 2

[0059] An improved mowing method for hilly grasslands comprises the following steps:

[0060] S1. Pre-install the side tillage racks 4 on both sides of the linkage assembly 5. Adjust and rotate the multiple telescopic nozzles 35 to their highest positions. The telescopic nozzles 35 are now extended to their longest positions, and the rubber elastic bands 37 are not in contact with the two switches 36. Fill the solid fertilizer tank 31 and the liquid fertilizer tank 32 with solid and liquid fertilizers, respectively. Check the status of the driving vehicle 1, fill the fuel tank of the driving vehicle 1, and then start the driving vehicle 1 and move it to the hilly area where the work is required.

[0061] S2: Rotate the servo motor 59. Under the action of the first screw 56 and the adjacent threaded barrel 52, the multiple telescopic nozzles 35 rotate downward. During the rotation, the telescopic ends of the telescopic nozzles 35 are compressed until the rubber elastic band 37 toggles the first switch 36. At this time, the solid-liquid pump 34 is turned on. The initial state of the electronically controlled three-way valve 33 is that the liquid fertilizer tank 32, the electronically controlled three-way valve 33, and the solid-liquid pump 34 are connected, that is, liquid fertilizer is sprayed into the air.

[0062] S3: The servo motor 59 is continuously started and lowered until the telescopic nozzle 35 is compressed to the shortest position to which it can be shortened. At this time, the rubber elastic band 37 continues to shift the second switch 36, and the electronically controlled three-way valve 33 rotates. The liquid fertilizer tank 32 and the solid fertilizer tank 31 are now connected to the solid-liquid pump 34 through the electronically controlled three-way valve 33, that is, the solid-liquid mixed fertilizer is sprayed on the ground. At this time, the coulter 44 partially extends into the soil to perform the tillage operation.

[0063] S4, the servo motor 59 is further started, driving the telescopic nozzle 35 to extend. At this time, the rubber elastic band 37 pulls back the switch 36 at the rear to form a solid fertilizer tank 31. The electric three-way valve 33, i.e., the solid-liquid pump 34, supplies solid fertilizer to the telescopic nozzle 35. In other words, solid fertilizer is sprayed on the ground and the plowed land. At this time, the coulter 44 is basically fully inserted into the soil for deep plowing operation.

[0064] S5, start the servo motor 59 to rotate in the reverse direction, at this time drive the telescopic nozzle 35 to shorten, turn the rear switch 36 to adjust the electric three-way valve 33 back to the state of S3, continue to start the servo motor 59 in the reverse direction, that is, after S2, it finally returns to the initial state of S1, and when the telescopic nozzle 35 returns to the initial state of the support tube 51, the electric three-way valve 33 will also be restored, and the side tillage frame 4 will not contact the ground.

[0065] In summary, the device is operated using this set of methods, which not only makes the overall adjustment and operation relatively simple, but also can effectively adapt to work in mountainous environments, and different fertilization heights, fertilization methods and fertilization ranges can be selected according to different usage environments.

[0066] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact via another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0067] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned implementation rules. The above-mentioned implementation rules and description are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
