Problems solved by technology

[0003]The existing tillage machinery has a fixed distance between the rotary tiller knives and cannot adjust the distance between the ridges according to the farming needs. Different types of rotary tiller knives are required for different cultivated lands , which greatly increases the cost of farming. Therefore, the purpose of the present invention is to provide a cultivator with adjustable width between ridges to solve the problem that existing tillage machines cannot adjust the distance between ridges according to farming requirements.

Embodiment 1

[0057] see Figure 1-Figure 9 As shown, the purpose of this embodiment is to provide a field cultivator with adjustable width between ridges, including a rotary tiller frame 1 and a rotary tiller mechanism 2 installed on the rotary tiller frame 1. The rotary tiller mechanism 2 includes :

[0058] Rotary tillage shaft 201, a driven gear 1034 is nested in the center of the side wall surface of the rotary tiller shaft 201, the driven gear 1034 is fixedly connected to the side wall of the rotary tiller shaft 201, fixed cutters 301 are symmetrically arranged on both sides of the driven gear 1034, The fixed cutter 301 has the same structure as the movable cutter 302. The fixed cutter 301 is fixedly connected to the outer wall of the rotary tiller shaft 201 through the inner wall of the cutter seat 3021. A through hole 203 is opened at the center of the right side surface of the rotary tiller shaft 201, and the left and right sides of the through hole 203 are located at the edges. B...

Embodiment 2

[0067] In order to prevent soil from splashing into the rotary tiller shaft 201 through the adjustment groove 202, the following improvements are made on the basis of Embodiment 1:

[0068] see Figure 10-Figure 17 As shown, wherein, the shutter 4 includes at least a second movable plate 402, the second movable plate 402 is provided with a second telescopic slot 4021 with an opening on the left side, and both sides of the inner wall of the second telescopic slot 4021 are provided with second stoppers. Slot 40211, the first movable plate 401 is slidably installed in the second limiting groove 40211, and the center of the left surface of the first movable plate 401 is fixedly connected with the connecting block 4011, and the side walls at the front and rear ends of the first movable plate 401 are located at the right edge A second limit slider 4022 is fixedly connected to the second movable plate 402 , and a second limit slider 4022 is fixedly connected to the side wall at the r...

Embodiment 3

[0075] In order to meet the requirements for the disassembly of the rotary tiller tooth 3022, the following improvements are made on the basis of Embodiment 1:

[0076] see Figure 18 As shown, wherein, one end of the rotary cultivating tooth 3022 is fixedly connected with a connection seat 30221, the side wall surface of the connection seat 30221 is provided with a groove 30222, and the side wall surface of the groove 30222 is provided with a mounting hole 30212, and the connecting arm 30211 is installed in the concave hole through a bolt 30223. In the groove 30222, the connecting arm 30211 is inserted into the groove 30222, and is threadedly connected with the mounting hole 30212 through the bolt 30223, so that the rotary tiller 3022 can be installed on the connecting arm 30211, which is convenient for the separate removal or replacement of the rotary tiller 3022 .

Abstract

The invention relates to the technical field of cultivators, in particular to a width-adjustable field-ridge spacing cultivator. The width-adjustable field-ridge spacing cultivator comprises a rotary tillage machine frame and a rotary tillage mechanism installed on the rotary tillage machine frame, the rotary tillage mechanism comprises a rotary tillage shaft, a driven gear is installed at the center of the surface of the side wall of the rotary tillage shaft in a nested mode, fixed cutters are symmetrically arranged on the two sides of the driven gear, and threaded walls with opposite thread directions are symmetrically arranged on the side wall of a lead screw with the driven gear as the center; a lead screw nut is connected to the threaded walls in a threaded mode, connecting rods are arranged on the periphery of the side wall of the lead screw nut in an annular array mode, a tool apron is arranged on a movable cutter, and the movable cutter is matched with the lead screw through the lead screw nut to move left and right along an adjusting groove; and the spacing adjustment between the movable cutter and the fixed cutter is achieved, the requirement for field ridge spacing adjustment is met, further, the moving range of the movable cutter can be effectively limited through the adjusting groove, and the safety of the movable cutter is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cultivating machines, in particular to a field cultivating machine with adjustable width between ridges. Background technique [0002] The tiller is a common tool for agricultural land. In addition to plowing the land, the tiller can also perform ridging work for the crops that need to be ridden. [0003] The distance between the rotary tilling knives of the existing tillage machinery is fixed, and the distance between the ridges cannot be adjusted according to the farming needs. Different types of rotary tilling knives are required for different cultivated lands, which greatly increases the cost of farming. Therefore, the purpose of the present invention is to A cultivator with adjustable width between ridges is developed to solve the problem that the existing tillage machines cannot adjust the distance between ridges according to farming requirements. Contents of the invention [0004] The object of ...
