Embodiment Construction
[0021] like Figure 1 to Figure 7 As shown, an embodiment of the present invention includes a sheet wheel 1, a counterweight box 2, and a rear frame 4 hinged to the main frame 3 that can swing left and right, and the sheet wheel 1 is arranged on the rear frame through a mounting seat 5 4 lower side, the counterweight box 2 is arranged on the upper side of the rear frame 4, and also includes a box frame 6, the counterweight box 2 is fixed on the box frame 6, and the front end of the box frame 6 is connected to the main frame 3 , the connection mode between the box frame 6 and the rear frame 4 is an up and down micro-movement structure, the bottom of the box frame 6 is provided with a first coupling part 7, and the corresponding position of the rear frame 4 is provided with a second coupling part 8 , the first coupling part 7 and the second coupling part 8 are in sliding contact or rolling contact.
[0022] Its principle is: in order to solve the problem that the counterweight ...

A mini-tiller resistive device comprises lamellar wheels, a counterweight box and a rear frame hinged to a main frame and capable of rocking side to side; the lamellar wheels are arranged under the rear frame. The mini-tiller resistive device also includes a box carrier; the front end of the box carrier is connected to the main frame; the counterweight box is fixed to the box carrier; a first connection portion is arranged at the bottom of the box carrier; the rear frame is provided with a second connection portion correspondingly; the first connection portion and the second connection portionare in sliding contact fit or rolling contact fit. The mini-tiller resistive device has the advantages that the problem is avoided that the counterweight box rocks side to side with the rear frame during steering of a whole mini-tiller, weight of the counterweight box is transmitted to the rear frame, and the demand for the rear frame to freely rock side to side with steering of the mini-tiller is met; since the counterweight box and the box carrier are connected to the main frame, operating stability of the mini-tiller is enhanced and shock absorption is provided for the whole mini-tiller; stability of a handle rack is enhanced, and the mini-tiller is more convenient to operate.
Description
technical field [0001] The invention relates to a structure of a tiller, in particular to an improved structure of a resistance device of the tiller. Background technique [0002] Most of the micro tillage machines in the prior art are equipped with a rod-shaped resistance device at the rear end of the machine body. Due to the difference in softness and hardness of the land and the required plowing depth, the plowing can be adjusted by adjusting the depth of the resistance device inserted into the soil surface. depth. Adjust the positioning hole of the resistance device upward, and the deeper it is inserted into the soil surface, the greater the resistance to the ground will be, the forward speed of the body will be relatively slowed down, and the plowing field will be deeper; otherwise, the resistance will be small, and the plowing field will become shallower. The inventor's Chinese patents whose notification numbers are CN204206737U and CN206909052U disclose a resistance ...
