Description

Cultivator Subsoiler Topdressing Machine

technical field

The utility model belongs to the technical field of agricultural machinery engineering, and is particularly suitable for a high-yield and high-efficiency cultivation method for corn.

Background technique

Most of the existing intertillage and subsoiling machines in our country are conventional plows. The conventional subsoiling plow has a soil dividing plate with a wide opening, and most of them are ridges. The conventional plow is not easy to penetrate the soil, and the depth of subsoiling cannot reach the technical level Requirements: The use of conventional subsoiling plows in drought years will not only fail to retain water, but will also aggravate the drought.

Rain-fed agricultural areas often encounter summer droughts and droughts during the growth of crops. Intertillage and deep loosening can effectively store precipitation, improve the efficiency of natural precipitation utilization, and meet the water needs of crop growth and development as much as possible to achieve high yield and high efficiency. .

Contents of the invention

The purpose of the utility model is to solve the problems of farmland water and soil loss caused by summer drought and torrential rain in rain-fed agricultural areas and to break the bottom of the soil plow, improve the utilization efficiency of natural precipitation, realize the sustainable utilization of soil resources and water resources, and avoid the damage caused by plow plow farming. Soil water loss, affecting yield, low benefit and other issues.

The utility model aims at the natural characteristics of the rain-fed agricultural area in Northeast China, and combines the actual situation of the existing power in the rural areas of Jilin Province, and designs a new type of tillage implement. The design strives to be multi-functional, subsoiling, intertillage and fertilization are carried out simultaneously. It consists of a fertilization box 1, a suspension frame 2, a ground wheel 3, a transmission chain 8, and subsoiling components. The frame 2 is equipped with fastening bolts 7 The subsoiling plow 4 is fixed, the fertilizer distribution pipe 5 is positioned at the rear side of the subsoiling plow, the fertilizer distribution pipe 5 is connected with the fertilizer delivery pipe 9, and the afterbody of the frame 2 is fixed with the intertillage plow 6. The subsoiling plow adopts a heel-type subsoiling shovel with a wall thickness of less than 2cm. The soil is subsoiled in strips. The depth of the subsoiling can be adjusted from 0 to 30cm, which is much larger than the working depth of the existing cultivator. Increase without overturning the soil. After loosening, depending on the soil moisture, it can be ridden or not, so that the soil is in a good soft state.

Machine performance:

Deep Loosening Adjustable 0-30cm

Deep pine width 5-10cm

Fertilization amount adjustable 0-800kg/hm ²

Working speed depends on supporting power

Supporting power requires more than 25 horsepower

Adapt to ridge width 60-70cm

Advantages and positive effects of the utility model

This machine has changed the drawbacks of conventional subsoiler plows, which have shallow penetration into the soil and much soil breaking, and adopts knife-heel narrow-width subsoiler technology, which is beneficial to farming under dry soil conditions. Deep into the soil, less soil breaking, no overturning of the soil, and more water storage, avoiding soil erosion, improving the efficiency of natural precipitation utilization, creating a plow layer soil reservoir, which can be used in summer and autumn to meet the water demand for crop growth and development. The machine tool is simple and reliable, has strong practicability, common parts, improves output, saves cost and increases efficiency.

Tests have proved that, compared with conventional conventional plows, the water content of the soil in the 0-40cm plow layer from June 25th to August 25th can be increased by 0.1-1.0 percentage points.

Detailed ways

Referring to accompanying drawing 1, it is made up of fertilization box 1, suspension frame 2, ground wheel 3, transmission chain 8, subsoiling part, fixes subsoiling plow 4 with fastening bolt 7 on the frame 2, and fertilization pipe 5 is positioned at deep The rear side of the loose plow is connected with the fertilizer delivery pipe 9 above the fertilizer distribution pipe 5, and the afterbody of the frame 2 is fixed with the intertillage plow 6. The subsoiling plow adopts a knife-heel subsoiling shovel with a wall thickness of 2cm. The soil is subsoiled in strips, and the depth of the subsoiling is adjustable from 0 to 30cm.

The invention is a subsoiling, intertillage and fertilization compound operation machine, which is mainly used for field intertillage of upland crops such as corn, sorghum and soybean. Generally, in the mid-growth period of upland crops, the depth of subsoiling is determined according to the soil moisture conditions and precipitation conditions at that time. When the soil moisture is sufficient, subsoiling, intertillage, and topdressing can be carried out at the same time. If there is a drought, the depth of topdressing should be shallower, and the intertillage plow may not be used. Subsoiling and topdressing can be combined to avoid excessive soil moisture loss and affect crops. grow.

Example:

Example 1: Corn Production Field Test
