Problems solved by technology

This has brought a new problem, which is to directly affect the land utilization rate, resulting in a reduction in yield per mu, and economic losses to growers.
In order to solve this problem, it can be overcome by enlarging the area of ​​individual paddy fields, but this creates another new problem. An excessively large paddy field area will cause an increase in the relative height difference of the terrain, resulting in uneven water storage depths in paddy fields, which is not conducive to seedlings. to grow
It is an obstacle to the popularization and implementation of new agricultural techniques

Embodiment 1

[0025] Such as figure 1 As shown, a paddy field level ground weeder includes a frame 1, the frame 1 is made of a hard material (such as steel), and the front end of the frame 1 is provided with three articulated points 2 arranged in the shape of a character , the articulation point 2 is used to realize the articulation of the frame 1 and the traction vehicle. At the end of the frame 1 opposite to the attachment point 2, a flat scraper 3 is provided. The cross section of the flat scraper 3 is a C-shaped structure, and the inner side of the C-shaped opening forms a concave surface of the flat scraper 3, and the concave surface of the flat scraper 3 The direction of the opening is the same as the direction of operation. A scraper hinge ear 3-1 and a mode adjustment ear 3-2 are fixed on the concave surface of the flat scraper. There is at least one scraper hinge ear 3-1. It is fixed on the frame 1 in a hinged form, so that the flat ground scraper 3 and the frame 1 are kept flat ...

Embodiment 2

[0034] In order to reduce the resistance generated by the leveling scraper 3 during the traveling operation and facilitate the discharge of residual soil in a predetermined direction, this embodiment is realized by adjusting the vector of the leveling scraper 3 relative to the working direction. This embodiment 2 is based on the embodiment 1, and the frame 1 in the embodiment 1 is further improved, and it is designed to be composed of the first frame 1-1 and the second frame 1-2. .

[0035] Such as figure 2 As shown, the first frame 1-1 is a rectangular frame structure, and the side adjacent to the towing vehicle is provided with a articulated point 2 arranged in the shape of a character, and the other side opposite to the articulated point 2 is provided with an outer frame. Ring 6-1. The second frame 1-2 is provided with an inner ring 6-2 matched with the outer ring 6-1, and the outer ring 6-1 and the inner ring 6-2 are nested to connect the first frame and the second mach...

Embodiment 3

[0041] In order to realize the ground profiling of the flat ground scraper 3 in this implementation force, on the basis of Embodiment 1 and Embodiment 2, in this embodiment, the attachment point 2 of the frame 1 or the first frame 1-1 and the traction vehicle The connection method is improved so that it can achieve ground profiling by twisting the direction during operation.

[0042] Since the traditional agricultural implement traction vehicles are all provided with the same layout as described in this application, the hitch point 2 is arranged in the shape of a character, and the independent hitch point located on the upper part is used for fixedly connecting the farm implement, which plays the role of stabilizing the farm implement and the lever fulcrum. An oil cylinder is respectively provided at the two symmetrically arranged mounting points at the lower part, and the oil passages of the two oil cylinders are connected in parallel, which act as lever power arms and are use...

Abstract

The invention discloses a paddy field land leveling and weeding all-in-one machine. A machine frame of the machine is connected with a traction vehicle through a hanging point, the machine frame is further provided with a land leveling scraping plate, and the machine is characterized in that the land leveling scraping plate can be switched between a first operation mode and a second operation mode through adjustment of a mode switching executing mechanism so as to adapt to land leveling and weeding operation. One machine with multiple purposes is realized.

Description

technical field [0001] The application belongs to the field of agricultural tools, and in particular relates to a paddy field leveling weeder. Background technique [0002] Rice is one of the main grain crops in my country, and its planting area accounts for about one-third of the total grain planting area in the country. Among all rice industrialized planting models, paddy field planting is in an absolute dominant position. For many years, paddy field planting has adopted the agronomy of raising seedlings first and then transplanting seedlings. However, with the increase in labor costs year by year, in recent years, the proportion of new agronomy such as rice direct seeding and field mechanized planting and harvesting has increased year by year, but compared with traditional agronomy, it still cannot be formed. mainstream. The bottom line is mechanized planting and harvesting. In the application of traditional paddy field planting, it is necessary to reserve a certain wid...
