DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The embodiment of the present application discloses a portable dual-mode agricultural machine.

[0036] Reference Figure 1 The transmission shaft 2 is installed on the agricultural machine body 1 in a vertical direction and is used to rotate under the drive of the agricultural machine body 1. In this embodiment, the agricultural machine body 1 is a hand-held diesel micro-tiller, and the transmission shaft 2 is coaxially connected to the output shaft of the diesel engine on the agricultural machine body 1.

[0037] Reference Figure 1 、 Figure 2 The adjusting seat 3 is slidably installed at the bottom of the agricultural machine body 1 in the vertical direction, the tilling blade 4 is rotatably installed on the adjusting seat 3, and the positioning member 5 is installed on the adjusting seat 3. The positioning member 5 is used to position the adjusting seat 3 on the agricultural machine body 1. In this embodiment, the positioning member 5 includes a positioning pin, which is slidably penetrated on the adjusting seat 3. A plurality of through holes for the positioning pins to pass through are spaced apart on the agricultural machine body 1 along the sliding direction of the adjusting seat 3.

[0038] The user drives the adjustment seat 3 to slide vertically, and the adjustment seat 3 drives the plowing blade 4 to slide, so as to adjust the height of the plowing blade 4. Then, the positioning pin passes through the adjustment seat 3 and through the through hole opened on the agricultural machine body 1, so as to position the adjustment seat 3, and then position the plowing blade 4 at the adjusted height, so as to conveniently adjust the height of the plowing blade 4, so that the height of the plowing blade 4 can be increased when the agricultural machine body 1 is moving, thereby ensuring the passability of the agricultural machine body 1 and reducing the possibility of the plowing blade 4 being damaged by collision with hard objects on the road when the agricultural machine body 1 is moving. When plowing is needed, the plowing blade 4 can be lowered for plowing.

[0039] Reference Figure 1 、 Figure 2 The first transmission mechanism 6 is installed on the agricultural machine body 1.

The length of the telescopic rod 61 is retractable. The telescopic rod 61 includes a connecting sleeve 611, a connecting rod 612 and a connecting pin 613. The connecting sleeve 611 is coaxially installed on the transmission shaft 2. The connecting sleeve 611 is hollow inside and has an opening at the lower end. The connecting rod 612 is slidably inserted on the connecting sleeve 611. The internal openings of the connecting rod 612 and the connecting sleeve 611 are both circular, so that the connecting rod 612 can rotate in the connecting sleeve 611. The first bevel gear 62 is rotatably installed on the adjusting seat 3. The first bevel gear 62 is coaxially connected to the connecting rod 612. The second bevel gear 63 is coaxially installed on the plowing blade 4, and the second bevel gear 63 is meshed with the first bevel gear 62.

[0040] When the adjusting seat 3 moves to adjust the height of the tiller 4, the adjusting seat 3 drives the first bevel gear 62, the second bevel gear 63 and the connecting rod 612 to move synchronously, so that the first bevel gear 62 and the second bevel gear 63 are always kept in meshing, thereby improving the stability of the meshing transmission of the first bevel gear 62 and the second bevel gear 63. After the adjusting seat 3 drives the tiller 4 to move to the required height, the connecting pin 613 is inserted into the connecting sleeve 611 and passes through the connecting hole on the connecting rod 612 relative to the connecting sleeve 611, and the connecting rod 612 can be locked on the connecting sleeve 611. The transmission shaft 2 drives the connecting sleeve 611 to rotate, and the connecting sleeve 611 can drive the connecting rod 61 2 rotates, the connecting rod 612 drives the first bevel gear 62 to rotate, the first bevel gear 62 drives the second bevel gear 63 to rotate, and the second bevel gear 63 drives the tilling blade 4 to rotate, so as to drive the tilling blade 4 to perform rotary tillage operation. When the agricultural machine body 1 is transported, the connecting pin 613 is pulled out from the connecting hole of the connecting rod 612 to release the lock of the connecting rod 612 on the connecting sleeve 611. When the connecting sleeve 611 rotates, it no longer drives the connecting rod 612 to rotate, so as to release the drive of the tilling blade 4 when the transmission shaft rotates, thereby reducing the ineffective drive of the tilling blade 4 when the agricultural machine body 1 is transported, thereby reducing the power consumption of the agricultural machine body 1 when it is transported.

The user can then rotate the support seat 9 upward, and the support seat 9 drives the wheel body of the walking wheel 7 to rotate to an inclined upward state, and then twist the double-headed screw 1032 in the opposite direction, so that the two unlocking blocks 1031 drive the two locking blocks 102 closer to each other, and the two locking blocks 102 respectively abut against the two sides of the locking gear 101, locking the locking gear 101, and then locking the support seat 9 and the walking wheel 7 at the current angle, reducing the impact of the wheel body of the walking wheel 7 on tillage during rotary tillage operations.

At this time, the walking wheel 7 is in contact with the ground to support the agricultural machine body 1, and then the plug connector 85 is plugged into the fifth bevel gear 83. When the agricultural machine body 1 drives the transmission shaft 2 to rotate, the transmission shaft 2 drives the walking wheel 7 to rotate, thereby conveniently driving the agricultural machine body 1 to be transported to the farming area. The agricultural machine body 1 is transported to the farming area After entering the domain, the tilling machine body 1 is lifted up by the jacking mechanism 11, the plug connector 85 is pulled out from the fifth bevel gear 83, and the support seat 9 is driven to drive the wheel body of the walking wheel 7 to rotate upward, and the support seat 9 is locked by the locking mechanism 10, and then the adjustment seat 3 is driven to drive the tilling blade 4 to move down to a height that contacts the soil, the adjustment seat 3 is locked, and the connecting pin 613 is inserted into the connecting sleeve 611 and the connecting rod 612, and the jacking mechanism 11 is retracted. When the transmission shaft 2 rotates, the tilling blade 4 can be driven to rotate to rotary till the land, simplifying the installation and removal of the walking wheel 7 and the tilling blade 4 and the operation of carrying the tilling blade 4 extra during the transportation of the tilling machine body 1, thereby improving the problem of time-consuming and labor-intensive use of small tilling machines.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
