Hydraulic motor driven cultivator capable of getting assistant adjustment by left and right hydraulic pressure at any moment

Abstract

The hydraulically motor driving cultivator is drawn with one standard farm tractor to complete weeding, ditching, scarifying and other jobs for row seeding crop. The present invention features the rotary weeding and scarifying cutter unit to cut soil continuously while the cultivator walks forwards, and the flexible right and left shifting of the weeding and scarifying cutter unit on the frame to avoid damage to crop. The shifting is completed through controlling one hydraulic cylinder to regulate the position of the cutter unit on the frame tracks.

Description

Technical field [0001] The invention belongs to agricultural cultivating machinery. It is a kind of suspended hydraulic transmission agricultural machine used in conjunction with agricultural standard wheeled tractors to remove weeds in the inter-row fields of wide-sowed crops and play a role in loosening the soil and preserving moisture. Background technique [0002] "At noon on the day of hoeing, the sweat drips down the soil. Who knows that the food on the plate is all hard work." This is one of the two poems of "Compassion for Farmers", which is an eternal masterpiece created by Tang Dynasty poet Li Shen, which shows the farming people at that time It also proves that the hoes that we are reluctant to use due to certain circumstances have been used for thousands of years. So let's start with the hoe. This tool requires us to hold our hands tightly and chop down the weeds in the farmland, because we are carefully watching the weeds being hoed one by one. Weeds are cut a...

Problems solved by technology

[0003] Now the work efficiency is higher than before, but there are some shortcomings and disadvantages in the quality of work.

The main manifestations are as follows: 1. The first intertillage cannot be carried out early in order to preserve soil moisture, because the root system of the crops is not yet developed and the seedlings are still young. Seedlings; 2. The depth of intertillage is difficult to grasp. For some soft soils, if the blade angle is not adjusted properly, the blade will penetrate too deep into the soil and easily damage the root system of the crop. For some hardened soils, the blade cannot penetrate the soil well. Weeding and soil loosening can only be solved by increasing the number of intertillages; 3. After plowing, the surface soil is not loose and flat, and there are many phenomena of dragging piles and pulling ditches, because the shovel is not like a hoe when weeding. After the soil is cut and hoed, the ground surface is loose and broken. It is dragged and cut into the ground to scrape and cut in the same way as the previously used three-toothed cultivating hoe blade to achieve the purpose of weeding and loosening the soil. Therefore, the drag pile 4. Under the premise of ensuring that the roots and stems of the crops are not damaged, the width of the seedling protection belt cannot be well compressed and maintained. Because the front wheel of the tractor deviates slightly, it is fixed on the suspension frame behind the tractor. The shovel or soil cultivator will swing violently left and right, and then the shovel will move after it becomes loose or encounter crookedness caused by poor sowing quality, so that the shovel will bury, press and shovel seedlings from time to time.

[0004] Whenever the above-mentioned situation occurs, the co-pilot will stop immediately. After parking, re-adjust the position of the blade on the suspension frame or raise the cultivator to align the driving direction of the tractor and start again. Under the circumstances, the working time is increased. Due to these shortcomings and shortcomings, after intertillage, we unsatisfiedly picked up the hoe again and manually hoeed the weeds on the missed tillage.
