[0038] Please refer to Figures 1 - 4 。

[0039] Some embodiments of this application disclose a chemical agent application mechanism, including a chemical agent tank 1, a discharge pipe 2 and a chemical agent dosage regulation component.

[0040] The medicine tank 1 is used to hold medicine. The medicine tank 1 is connected to the tractor through the first frame 3. The first frame 3 supports and fixes the medicine tank 1. The tractor drives the first frame 3 to move, and the medicine tank 1 moves synchronously with the first frame 3.

[0041] Above the medicine tank 1 is the medicine inlet, and below the medicine tank 1 is the discharge port. A discharge pipe 2 is provided at the discharge port. The medicine in the medicine tank 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 where the medicine application mechanism sprays medicine.

[0042] The medicine dosage control component is used to adjust the application amount of the medicine according to the thickness of the crop residue on the ground, reducing the occurrence of excessive spraying of the medicine.

[0043] In some embodiments, the medicine dosage control component includes a valve, an L-shaped push rod 4, a spring 6, an angle sensor 5 and a controller.

[0044] Among them, the valve is arranged on the discharge pipe 2 and is used to adjust the discharge amount of the discharge pipe 2.

[0045] 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 a roller 15. The L-shaped push rod 4 is inclined backward relative to the vertical direction, and the L-shaped push rod 4 can swing back and forth with the undulation of the cultivated land.

[0046] 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.

[0047] Both ends of the spring 6 are respectively connected to the L-shaped push rod 4 and the first frame 3. As Figure 2 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 a downward pressure to the L-shaped push rod 4 to ensure that the roller 15 can always be in contact with the ground. It should be noted here that the front and back are based on the running direction of the tractor. The movement direction of the tractor is the front, and the direction opposite to the movement direction of the tractor is the back.

[0048] The controller is communicatively connected to the angle sensor 5 and the valve. The controller is used to obtain the thickness of the crop residue 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 medicine according to the thickness of the ground residue, and adjust the opening degree of the valve.

[0049] The tractor drives the chemical application mechanism to run on the cultivated land. The roller 15 moves up and down 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 residue 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.

[0050] The thickness of the ground residue is obtained as follows. As Figure 4 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 connecting rod. According to the trigonometric relationship, H4 (the height between the roller 15 and the first frame 3 before the L-shaped push rod 4 enters the cultivated land) and H4' (the height between the roller 15 and the first frame 3 after the L-shaped push rod 4 enters the cultivated land) are obtained. The thickness of the ground crop residue is H1, and H1 = H4' - H4.

[0051] The application amount of the chemical is determined according to the thickness of the ground crop residue, and the application amount is adjusted by the opening of the valve. Specifically, when the thickness of the ground crop residue is relatively thick, the opening of the valve is large, and when the thickness of the ground crop residue is relatively thin, the opening of the valve is small.

[0052] In this solution, the chemical amount control component is located in front of the chemical tank 1. First, the thickness of the ground crop residue is obtained through the chemical amount control component, and then the controller adjusts the opening of the valve according to the thickness of the ground crop residue. The chemical application mechanism disclosed in this solution can detect the thickness of the ground crop residue on the cultivated land in real time, and then realize the real-time adjustment of the application amount of the chemical according to the thickness of the ground crop residue.

[0053] Optionally, when the thickness of the ground crop residue is within a certain range, the application amount of the chemical is a certain value. When the thickness of the ground crop residue is within another range, the application amount of the chemical is another value. This design method can reduce the adjustment times of the valve opening and extend the service life of the valve.

[0054] The ground crop residue can be residues such as straws and stubbles, and the chemical can be a composting agent or a fertilizer, etc.

[0055] In some embodiments, the medicament application mechanism disclosed in this solution further includes a ranging sensor for detecting the distance H4 between the first frame 3 and the surface of the ground crop residue, which can be obtained directly without calculation, reducing the error of the thickness of the ground crop residue caused by the errors of other parameters. Furthermore, the distance between the first frame 3 and the surface of the ground crop residue detected by the ranging sensor is used to verify the height obtained by calculation, so as to ensure the accuracy and reliability of the result of the medicament application amount.

[0056] The medicament application mechanism disclosed in this solution further includes a rotary tiller 7, which is installed on the first frame 3 and is located downstream of the medicament tank 1. It has the ability to break up the soil, and can fully mix the ground crop residue, medicament and soil, improving the ability of the medicament to act on the ground crop residue.

[0057] In this solution, the rotary tiller 7 is integrated on the medicament application mechanism. After applying the medicament to the ground crop residue through the medicament tank 1, the rotary tiller 7 is used to break up the soil, turning the ground crop residue and the medicament deep into the soil, replacing manual soil turning and reducing the labor intensity.

[0058] The medicament application mechanism disclosed in this solution not only has the ability to apply medicament, but also has the ability to stir the ground crop residue, medicament and soil. It has comprehensive functions and can improve the market competitiveness of the medicament application mechanism to a certain extent.

[0059] The medicament contained in the medicament tank 1 can be a liquid medicament or a solid medicament.

[0060] When the medicament contained in the medicament tank 1 is a solid medicament, a screw agitator 8 is arranged in the medicament tank 1 of the medicament application mechanism disclosed in this solution. The screw agitator 8 is used to stir the medicament in the medicament tank 1 to prevent the medicament in the medicament tank 1 from caking and affecting the application of the medicament.

[0061] This solution also discloses a tillage machine, which includes hammer claws 9 and a medicament application mechanism. The medicament application mechanism is the medicament application mechanism described in any of the above solutions. Since the medicament application mechanism has the above technical effects, the tillage machine with this medicament application mechanism also has the same technical effects, which will not be elaborated here.

[0062] The hammer claws 9 are installed on the second frame 12. The second frame 12 is connected to the first frame 3 of the medicament application mechanism. The hammer claws 9 are located upstream of the medicament application mechanism, and the second frame 12 is connected to the tractor.

[0063] During operation, the tractor pulls the tillage machine to run on the cultivated land. The hammer claws 9 first crush the crops such as straw and stubble on the cultivated land to obtain ground crop residue. Then the medicament application mechanism applies medicament to the ground crop residue. Finally, the rotary tiller 7 turns the mixture of the crushed medicament and the ground crop residue deep into the soil.

[0064] As Figure 1 and Figure 2 shown, in this solution, a baffle 10 is provided behind the hammer claw 9. The baffle 10 is used to separate the hammer claw 9 from the chemical agent application mechanism, preventing the ground crop residues broken by the hammer claw 9 from being lifted up and affecting the measurement accuracy of the ranging sensor and the angle sensor 5.

[0065] The baffle 10 is connected to the second frame 12 through a connecting plate. The shape of the baffle 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 10 does not affect the normal operation of the hammer claw 9.

[0066] Optionally, the baffle 10 is located at a position slightly above the rear of the hammer claw 9. On the one hand, it prevents the baffle 10 from extending into the ground crop residues, increasing the resistance of the tillage machine during tillage operation. On the other hand, the ground crop residues crushed by the hammer claw 9 will be lifted up under the rotation of the hammer claw 9. In this embodiment, the set position of the baffle 10 can better block the lifted ground crop residues.

[0067] The tillage machine disclosed in this solution further includes a press wheel 11. The press wheel 11 is connected to the first frame 3 of the chemical agent application mechanism through a third frame 13. The press wheel 11 is located downstream of the rotary tiller 7 of the chemical agent application mechanism and is used to turn the ground crop residues and the chemical agent deep into the soil below for compacting the soil.

[0068] The tillage machine disclosed in this solution integrates functions such as crushing ground crops, applying chemical agents, deep plowing, and compacting. The above four operations are completed through a single operation, saving the time of farming operations and improving farming efficiency.

[0069] The press wheel 11 is connected to the third frame 13 through a telescopic cylinder 14. The telescopic cylinder 14 is used to adjust the height of the press wheel 11 to control whether the press wheel 11 compacts the soil and the force with which the press wheel 11 compacts the soil.

[0070] Specifically, the telescopic cylinder 14 lifts the press wheel 11 until the press wheel 11 does not contact the cultivated land. At this time, the press wheel 11 cannot compact the soil, reducing the resistance of the tillage machine during tillage or road operation; when the press wheel 11 contacts the cultivated land, the telescopic cylinder 14 adjusts the height of the press wheel 11 to adjust the pressure of the press wheel 11 on the soil.

[0071] The second frame 12 is connected to the tractor through a suspension mechanism. The suspension mechanism can be a two-point suspension mechanism or a three-point suspension mechanism.

[0072] The tractor is connected to the second frame 12 through a three-point suspension mechanism. The three-point suspension mechanism is connected to the body of the tractor with three hinge points. The second frame 12 has better stability when traveling straight with the tractor and is suitable for small and medium power tractors.

[0073] As shown Figure 1 in the figure, 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. The lower pull rod is connected to the second welding bracket. Shaft holes for articulated connection with the tractor are provided on both the upper pull rod and the lower pull rod.

[0074] In some embodiments, the tractor is connected to the second frame 12 through a two-point suspension mechanism. The two-point suspension mechanism is coupled to the fuselage of the tractor at two articulated points to correct the driving direction more easily and is applicable to high-power tractors.

[0075] The above description is only for the preferred embodiments of the present application and the description of the applied technical principles, and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. The scope of the application involved in this application is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in the present application.
