[0024] See also Figure 1-Figure 4 .

[0025] Some embodiments of the present application disclose a medicine application mechanism, including a medicine box 1, a discharge pipe 2 and a medicine dosage control component. The medicine box 1 is used to contain medicines. The medicine box 1 is connected to the tractor through the first frame 3. The first frame 3 supports and fixes the medicine box 1. The tractor drives the first frame 3 to move, and the medicine box 1 moves synchronously with the first frame 3. The top of the medicine box 1 is a medicine inlet, and the bottom of the medicine box 1 is a discharge port. The discharge port is provided with a discharge pipe 2. The medicine in the medicine box 1 is discharged to the cultivated land through the discharge pipe 2. Optionally, the discharge pipe 2 is arranged perpendicular to the forward direction of the tractor to increase the area of ​​the medicine application mechanism spraying the medicine. The dosage control component is used to control the dosage of the pesticide according to the thickness of the crop waste residue on the ground, reduce the occurrence of excessive spraying of the pesticide, and thus reduce resource waste and environmental pollution.

[0026] In some embodiments, the drug dosage control assembly includes a valve, an L-shaped push rod 4, a spring 6, an angle sensor 5 and a controller. Wherein, the valve is arranged on the discharge pipe 2 to adjust the discharge amount of the discharge pipe 2; One end of the L-shaped push rod 4 is hinged to the first frame 3, and the other end of the L-shaped push rod 4 contacts the cultivated land through the roller 15. The L-shaped push rod 4 is tilted backward relative to the vertical direction, and the L-shaped push rod 4 can swing forward and backward with the ups and downs of the cultivated land; The L-shaped push rod 4 includes a first push rod and a second push rod, one end of the second push rod is hinged to the first frame 3, the other end of the second push rod is fixedly connected to one end of the first push rod, and the other end of the first push rod is connected to the roller 15. The angle sensor 5 is installed on the first frame 3 and is used to collect the angle between the second push rod of the L-shaped push rod 4 and the vertical direction; The two ends of the spring 6 are connected to the L-shaped push rod 4 and the first frame 3 respectively. Figure 2 As shown, one end of the spring 6 is connected to the first push rod, and the other end of the spring 6 is connected to the first frame 3. The spring 6 is used to apply downward pressure to the L-shaped push rod 4 to ensure that the roller 15 can always contact the ground. It should be noted here that the front and back are based on the running direction of the tractor. The moving direction of the tractor is the front, and the direction opposite to the moving direction of the tractor is the rear. The controller is communicatively connected with the angle sensor 5 and the valve. The controller is used to obtain the thickness of the crop debris on the ground according to the angle collected by the angle sensor 5, the lengths of the first push rod and the second push rod, and the angle of the L-shaped push rod 4, and obtain the application amount of the agent according to the thickness of the ground debris, and adjust the opening of the valve.

[0027] The tractor drives the pesticide application mechanism to operate on the cultivated land, and the roller 15 moves with the height of the cultivated land, thereby driving the L-shaped push rod 4 to rotate. The angle sensor 5 collects the angle between the second push rod of the L-shaped push rod 4 and the vertical direction. The controller obtains the thickness of the ground crop debris based on the angle collected by the angle sensor 5, the lengths of the first push rod and the second push rod, and the corner of the L-shaped push rod 4.

[0028] The thickness of ground debris is obtained as follows: Figure 4 As shown, the length of the L-shaped push rod 4 includes a first push rod with a length of L1 and a second push rod with a length of L2. The angle between the second push rod and the vertical direction before the L-shaped push rod 4 enters the cultivated land is a, and the angle between the second push rod and the vertical direction after the L-shaped push rod 4 enters the cultivated land is a'. The corner b of the L-shaped push rod 4 is the angle between the first push rod and the second push rod. According to the trigonometric relationship, H4 (the height between the drum 15 and the first frame 3 before the L-shaped push rod 4 enters the cultivated land) and H4' (the height between the drum 15 and the first frame 3 after the L-shaped push rod 4 enters the cultivated land) are obtained, and the thickness of the crop debris on the ground is H1, and H1= H4'- H4.

[0029] The amount of the agent to be applied is determined according to the thickness of the crop residue on the ground, and the amount of application is adjusted by the opening of the valve. Specifically, when the thickness of the crop residue on the ground is thicker, the opening of the valve is large, and when the thickness of the crop residue on the ground is thinner, the opening of the valve is small.

[0030] In this solution, the dosage control component is located in front of the medicine box 1. The thickness of the crop debris on the ground is first obtained through the dosage control component, and then the controller adjusts the opening of the valve according to the thickness of the crop debris on the ground. The medicine application mechanism disclosed in this solution can detect the thickness of the crop debris on the ground of the cultivated land in real time, and then realize the real-time adjustment of the application amount of the medicine according to the thickness of the crop debris on the ground.

[0031] Optionally, when the thickness of the crop debris on the ground is within a certain range, the amount of the agent applied is a certain value, and when the thickness of the crop debris on the ground is in another range, the amount of the agent applied is another constant value. This design can reduce the number of times the valve opening is adjusted and extend the service life of the valve.

[0032] The ground crop residues may be residues of straw and stubble, etc., and the pesticide may be a composting agent or a fertilizer, etc.

[0033] In some embodiments, the pesticide application mechanism disclosed in the present scheme also includes a distance measuring sensor for detecting the distance H4 between the first frame 3 and the surface of the crop debris on the ground, without the need to obtain it through calculation, thereby reducing the error in the thickness of the crop debris on the ground caused by errors in other parameters; further, the distance between the first frame 3 and the surface of the crop debris on the ground obtained by detecting the distance measuring sensor is used to verify the height obtained by calculation, so as to ensure that the result of the application amount of the pesticide is accurate and reliable.

[0034] The pesticide application mechanism disclosed in this scheme also includes a rotary plow 7, which is installed on the first frame 3 and is located downstream of the pesticide box 1. It has the ability to crush soil and fully mix the ground crop debris, pesticide and soil to improve the ability of the pesticide to act on the ground crop debris.

[0035] This solution integrates a rotary plow 7 on the pesticide application mechanism. After the pesticide is applied to the crop debris on the ground through the pesticide box 1, the soil is broken up by the rotary plow 7, and the crop debris and the pesticide are turned deep into the soil, replacing manual tillage and reducing the intensity of manual labor.

[0036] The pesticide application mechanism disclosed in the present solution not only has the ability to apply pesticides, but also has the ability to stir ground crop debris, pesticides and soil. It has comprehensive functions and can improve the market competitiveness of the pesticide application mechanism to a certain extent.

[0037] The medicine contained in the medicine box 1 can be a liquid medicine or a solid medicine.

[0038] When the medicine contained in the medicine box 1 is a solid medicine, a spiral agitator 8 is provided in the medicine box 1 of the medicine application mechanism disclosed in this scheme. The spiral agitator 8 is used to stir the medicine in the medicine box 1 to prevent the medicine in the medicine box 1 from agglomerating and affecting the application of the medicine.

[0039] The present scheme also discloses a tilling machine, including a hammer claw 9 and a drug applying mechanism, wherein the drug applying mechanism is the drug applying mechanism recorded in any one of the above schemes. Since the drug applying mechanism has the above technical effects, the tilling machine having the drug applying mechanism also has the same technical effects, which will not be repeated here.

[0040] The hammer claw 9 is mounted on the second frame 12, the second frame 12 is connected to the first frame 3 of the medicine applying mechanism, the hammer claw 9 is located upstream of the medicine applying mechanism, and the second frame 12 is connected to the tractor.

[0041] During operation, the tractor pulls the tiller to operate on the cultivated land. The hammer claw 9 first crushes the crops such as straw and stubble on the cultivated land to obtain ground crop debris, and then the agent applying mechanism applies the agent to the ground crop debris. Finally, the rotary plow 7 turns the mixture of the crushed agent and the ground crop debris deep into the soil.

[0042] like Figure 1 and Figure 2 As shown, in this solution, a baffle 10 is provided behind the hammer claw 9 , and the baffle 10 is used to separate the hammer claw 9 from the agent applying mechanism to prevent the ground crop debris broken by the hammer claw 9 from being raised and affecting the measurement accuracy of the distance sensor and the angle sensor 5 .

[0043] The baffle plate 10 is connected to the second frame 12 via a connecting plate, and the shape of the baffle plate 10 is adapted to the shape of the cylindrical surface formed by the rotation of the hammer claw 9 to ensure that the design of the baffle plate 10 does not affect the normal operation of the hammer claw 9.

[0044] Optionally, the baffle 10 is located at a position slightly above and behind the hammer claw 9. On the one hand, it prevents the baffle 10 from extending into the ground crop debris and increasing the resistance of the tiller running on the cultivated land. On the other hand, the ground crop debris crushed by the hammer claw 9 will be lifted upward under the rotation of the hammer claw 9. The setting position of the baffle 10 in this embodiment can better block the lifted ground crop debris.

[0045] The tilling machine disclosed in this scheme also includes a pressing wheel 11, which is connected to the first frame 3 of the agent application mechanism through a third frame 13. The pressing wheel 11 is located downstream of the rotary plow 7 of the agent application mechanism and is used to turn the crop residues and agents on the ground deep into the soil to compact the soil.

[0046] The tilling machine disclosed in this scheme integrates the functions of ground crop crushing, application of pesticides, deep plowing and compaction, and completes the above four tasks in a single operation, saving farming operation time and improving farming efficiency.

[0047] The pressing wheel 11 is connected to the third frame 13 via a telescopic cylinder 14 , and the telescopic cylinder 14 is used to adjust the height of the pressing wheel 11 to control whether the pressing wheel 11 compacts the soil and the force with which the pressing wheel 11 compacts the soil.

[0048] Specifically, the telescopic cylinder 14 lifts the pressing wheel 11 until the pressing wheel 11 is no longer in contact with the cultivated land. At this time, the pressing wheel 11 cannot compact the soil, thereby reducing the resistance of the tiller running on the cultivated land or road surface; when the pressing wheel 11 is in contact with the cultivated land, the telescopic cylinder 14 adjusts the height of the pressing wheel 11 to adjust the pressure of the pressing wheel 11 on the soil.

[0049] The second frame 12 is connected to the tractor via a suspension mechanism, and the suspension mechanism may be a two-point suspension mechanism or a three-point suspension mechanism.

[0050] The tractor is connected to the second frame 12 through a three-point suspension mechanism, and the three-point suspension mechanism is connected to the body of the tractor at three hinge points. The second frame 12 has better stability when traveling in a straight line with the tractor, and is suitable for small and medium-power tractors.

[0051] like Figure 1 As shown, the three-point suspension mechanism includes an upper pull rod, a suspension support plate and a lower pull rod. The upper pull rod is welded to the second bracket through the suspension support plate, and the lower pull rod is connected to the second welded bracket. Both the upper pull rod and the lower pull rod are provided with shaft holes for hinged connection with the tractor.

[0052] In some embodiments, the tractor is connected to the second frame 12 via a two-point suspension mechanism, which is connected to the body of the tractor at two hinge points to correct the driving direction more easily, and is suitable for high-power tractors.

[0053] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept.
