Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and specifically discloses a miniature rotary tiller for mountain areas. Background Art

[0002] With the continuous improvement of science and technology, most of the tillage work on farmland has been achieved by mechanized operations. For example, operations such as rotary tillage, ridge forming, and trenching of farmland soil are all completed by different agricultural machinery.

[0003] In particular, the plowing and harrowing operations of farmland can be completed by special rotary tillers. Rotary tillers have the characteristics of strong soil crushing ability and flat surface after plowing, and have been widely used.

[0004] For plowing and harrowing operations in mountainous terrain, a mini rotary tiller can be used. The overall volume of the mini rotary tiller is smaller than that of the commonly used rotary tiller, which can better adapt to mountainous terrain and is more convenient to move on slopes.

[0005] In the prior art, after the plowing and harrowing operations are completed, the land needs to be fertilized or weeds need to be killed. The operation of fertilizing or killing weeds with pesticides can be carried out immediately after the land is plowed. However, the micro rotary tiller used in the prior art does not have the function of spraying pesticides, and cannot spray pesticides on the plowed land immediately during the plowing process.

[0006] Therefore, in view of this, the inventor provides a miniature rotary tiller for mountain use to solve the above-mentioned problems. Utility Model Content

Specifically, the driving structure comprises a diesel engine 2 and a gear transmission system installed between the main shaft and the output end of the diesel engine 2. The diesel engine 2 is used as a power source input, and the input power is transmitted to the main shaft through the gear transmission system to drive the main shaft to rotate, thereby driving the synchronous rotation of the rotating wheel and the rotary tillage cutter 5. In this embodiment, the installed rotary tillage cutter 5 is a rotary tillage cutter 5 commonly used in the prior art. The resistance tillage blade 8 installed at the rear of the frame 3 is also a resistance tillage blade 8 commonly used in the prior art.

[0026] A spraying assembly for spraying chemicals onto the ground after tillage is also mounted on the frame 3 .

[0027] The medicine spraying assembly includes a spray bracket fixedly mounted on the frame 3 and a medicine box 7 fixedly mounted on the frame 3 for storing medicine. A water outlet pipe is fixedly mounted on the spray bracket, and a plurality of spray heads 11 connected to the water outlet pipe are fixedly mounted below the spray bracket. A water outlet structure is arranged in the medicine box 7, and a connecting water pipe 6 is installed and connected between the water outlet structure and the water outlet pipe. A control structure for controlling and driving the water outlet structure to drain water is also arranged on the frame 3.

In this embodiment, the secondary wheels are divided into a first secondary wheel 9 and a second secondary wheel 12.

[0030] The control structure includes a cam fixedly mounted on the secondary shaft 13, an air cylinder 10 fixedly mounted on a support of a rotating shaft 19, a pneumatic mechanism mounted in a medicine box 7, and an air outlet pipe 16 mounted between the air outlet end of the air cylinder 10 and the pneumatic mechanism. Among them, the cam is an elliptical cam 14, the input end of the air cylinder 10 abuts against the elliptical cam 14, the internal chamber of the air cylinder 10 is divided into a ventilation chamber connected to the air outlet end and a power chamber 15 equipped with the input end, and a reset spring for pushing the input end of the air cylinder 10 outward is installed in the ventilation chamber of the air cylinder 10. The rotation of the secondary shaft 13 drives the elliptical cam 14 to rotate, and then the elliptical cam 14 cooperates with the reset spring to continuously reciprocate and abut against the input end to generate an airflow blowing toward the pneumatic mechanism.

[0031] The pneumatic mechanism includes a pneumatic box 21 coaxially fixedly mounted on the medicine box 7, a turntable mounted in the pneumatic box 21, and a plurality of fan blades 17 mounted on the turntable and driven by wind. In this embodiment, the medicine box 7 is provided with an opening covering the liquid outlet and for the pneumatic box 21 to be installed, a liquid outlet through hole is provided on the pneumatic box 21, an isolation pipe connecting the inner cavity of the medicine box 7 and the connecting water pipe 6 is installed inside the liquid outlet through hole, an air inlet connected to the air outlet pipe 16 is provided on one side of the bottom of the pneumatic box 21, and a one-way valve that can only exhaust air into the medicine box 7 is installed on the top surface of the pneumatic box 21 located in the medicine box 7. The airflow introduced by the air outlet pipe 16 blows toward the fan blades 17 through the air inlet, pushes the fan blades 17 and drives the turntable to rotate, and then is discharged into the medicine box 7 through the one-way valve.

[0032] like Figure 4 As shown, the water outlet structure includes a water outlet ring coaxially mounted on the top surface of the pneumatic box 21 but not covering the one-way valve, a water outlet conduit 18 fixedly mounted in the water outlet ring and having one end passing through the water outlet ring to communicate with the inner cavity of the medicine box 7, a rotating shaft 19 coaxially mounted in the water outlet ring, and a roller 22 circumferentially fixedly mounted on the outer side of the rotating shaft 19 and used to squeeze the water outlet conduit 18. A partition 20 for sealing and isolating the pipeline is installed at the bottom of the water outlet ring, and a through hole is opened on the partition 20 for only the free end of the water outlet conduit 18 to pass through, and the water outlet conduit 18 connects the inner cavity of the medicine box 7 with the connecting water pipe 6.

[0033] A ring groove is formed on the pneumatic box 21, and a connecting member that passes through the ring groove and connects to the rotating disk is fixedly installed on the outer wall of the rotating shaft 19. The connecting member includes a connecting ring plate and a fixed connecting rod fixed between the connecting ring plate and the rotating shaft 19. The connecting ring plate extends into the ring groove and is fixedly connected to the rotating disk, and the two ends of the connecting ring plate are respectively in contact with the end surfaces of the two ends of the ring groove.

[0034] When the utility model is used, the diesel engine 2 drives the main shaft to rotate through the gear transmission system, thereby driving the main wheel 4 and the rotary tillage cutter 5 to rotate, so as to realize the tillage operation in the mountainous terrain during the moving process;

[0035] During the tillage operation, the secondary wheel and the secondary shaft 13 are also driven to rotate synchronously, and the secondary shaft 13 synchronously drives the elliptical cam 14 to rotate to drive the air cylinder 10 to generate airflow. The airflow is introduced into the air box 21 from the air outlet pipe 16, pushing the fan blades 17 to drive the turntable to rotate, and synchronously drives the rotating shaft 19 to rotate through the connecting piece. The roller 22, the water outlet conduit 18, and the water outlet ring sleeve installed on the rotating shaft 19 form a peristaltic pump. The rotation of the rotating shaft 19 will drive the roller 22 to squeeze the water outlet conduit 18 to continuously discharge the liquid medicine in the medicine box 7, and introduce it into the water outlet pipe through the connecting water pipe 6, and finally spray it out through the sprinkler head 11, so that the cultivated land can be sprayed with the medicine, and the effects of fertilization or weeding can be achieved by storing different liquid medicines.

[0036] Moreover, when the frame 3 does not move, the secondary shaft 13 will not rotate, and the peristaltic pump will not work, and no liquid medicine will flow into the water outlet pipe. Therefore, there will be no spraying operation during the non-cultivation period.
