Description

A wheat and corn intercropping seeder suitable for saline-alkali land

Technical Field

The invention relates to the field of agricultural machinery, and in particular to a wheat and corn intercropping seeder suitable for saline-alkali land.

Background Art

Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil. Therefore, the alkalinity is generally high. Plants can hardly survive in severe saline-alkali soil areas. In the existing technology, water flushing is used to reduce the content of salt and alkaline substances in saline-alkali land. It is necessary to dig a pit first and then inject water for flushing. This method is inefficient and it is impossible to dig a planting pit in advance. Since flushing requires long-term irrigation in the dug planting pit, the salt and alkaline substances in the planting pit are mixed with water, and then the salt and alkaline substances are taken away by drainage. The planting pit dug in advance will be soaked in water for a long time, causing the soil in the planting pit to loosen, and then cause the planting pit dug in advance to collapse. That is, generally soaking and flushing will be carried out first and then digging the planting pit further, but as the planting pit is further dug, the salt and alkaline substances in the deeper soil will be brought out, resulting in the need for further flushing to remove the salt and alkaline substances, which greatly increases the working time.

Summary of the invention

In order to overcome the need to first dig a hole and then inject water for flushing, which is inefficient and cannot be dug in advance, and flushing requires long-term irrigation in the dug planting hole, the present invention provides a wheat and corn intercropping seeder suitable for saline-alkali land.

Optionally, the rolling roller is provided with convex strips with an arc structure.

The present invention has the following advantages: 1. The present invention is operated by a conveyor belt, that is, the conveyor belt rotates counterclockwise from the perspective of looking from right to left. During this process, the scraper on the conveyor belt continuously scrapes the soil in the saline-alkali land, and then the conveyor belt drives the soil to follow the movement, and then the soil enters the diversion trough, and then the soil moves to both sides of the saline-alkali land under the diversion effect of the diversion trough, that is, the soil accumulates on both sides of the saline-alkali land, avoiding the direct scraping method. Too much soil will accumulate in front of the first scraper, affecting the movement of the wheat and corn intercropping planter suitable for saline-alkali land in the saline-alkali land;

2. The present invention is staggeredly distributed with the nozzle and the second scraper, that is, in the process of digging the pit, the sprayed water can immediately wash the V-shaped pit, and further wash away the excessive salt and alkaline substances in the V-shaped pit. It should be noted that the V-shaped pit is the location for subsequent sowing, that is, the salt and alkaline substances therein need to be treated in a targeted manner to further reduce the content of salt and alkaline substances at the sowing location. In the process of digging the V-shaped pit, the second motor is controlled to drive the first connecting rod to reciprocate, and the first connecting rod drives the cleaning brush to rotate, that is, the cleaning brush is viewed from right to left. The cleaning brush rotates counterclockwise from the perspective of the second scraper to contact the second scraper, clean the soil attached to the second scraper, avoid excessive soil attached to the second scraper, affect the efficiency and quality of digging, and avoid the V-shaped pits of different sizes. At the same time, the soil dug out by the second scraper is pushed forward to make the soil contact with the conveyor belt. In this process, the conveyor belt drives the soil to move forward, and then moves to both sides of the saline-alkali land under the action of the guide plate to avoid the excavated soil staying in the dug V-shaped pit. In this process, the water flowing out of the funnel continuously cleans the residual soil on the cleaning brush;

3. Although the present invention can avoid the collapse of the V-shaped pit by covering the ground, the salt and alkaline substances in the covered land are difficult to discharge. The salt and alkaline substances can be discharged by opening through holes in the ground film, but opening too many through holes will make it impossible to limit the V-shaped pit, resulting in the collapse of the V-shaped pit. That is, the salt and alkaline substances are adsorbed by the through holes and the activated carbon cloth on the ground film, and the collapse of the V-shaped pit can be avoided at the same time. It should be noted that the discharge port is located directly above the ground film, that is, the soil discharged from the discharge port falls on the ground film, and then under the rolling of the rolling roller, the soil covers the ground film, thereby enhancing the firmness of the ground film and preventing the external wind from blowing the ground film and causing the ground film to separate from the saline-alkali land.

The ground membrane 203 is composed of two layers of membrane wrapped with a layer of activated carbon cloth, and is used to absorb salt and alkaline substances.

The rolling wheel 207 is configured to have a round pancake structure with a larger inner portion and a smaller outer portion, so as to adapt to the V-shaped pit.

The rolling roller 208 is provided with convex strips with an arc structure, which are used to squeeze the ground film 203 so that the ground film 203 is embedded in the saline-alkali land 1, thereby enhancing the bonding effect of the ground film 203.

Before the wheat and corn intercropping seeder suitable for saline-alkali land moves, the staff first stretches out the ground film 203, and then fixes the ground film 203 on the edge of the saline-alkali land 1, and then controls the fourth motor 204 to drive the second connecting rod 205 to rotate, the second connecting rod 205 drives the connecting plate 206 to rotate, the connecting plate 206 drives the rolling wheel 207 and the rolling roller 208 to contact the ground film 203, and then the wheat and corn intercropping seeder suitable for saline-alkali land moves forward, and at the same time controls the third motor 201 to drive the collecting wheel 207 and the rolling roller 208 to contact the ground film 203.

It should be noted that although the film covering method can prevent the collapse of the V-shaped pit, the covered land The salt and alkaline substances in the ground are difficult to be discharged, and the salt and alkaline substances can be discharged by opening through holes 203a on the ground film 203. However, if too many through holes 203a are opened, it will lead to the failure of limiting the V-shaped pit, resulting in the collapse of the V-shaped pit. That is, the salt and alkaline substances are adsorbed by the through holes 203a and the activated carbon cloth on the ground film 203, and the collapse of the V-shaped pit is avoided. In this process, the electric auger 2010 is controlled to rotate, that is, the electric auger 2010 drives the guide plate 9 to guide the mud on both sides. The soil enters the conveying pipe 209 through the feed port 209a, and then the soil in the conveying pipe 209 is discharged through the discharge port 209b driven by the electric auger 2010. It should be noted that the discharge port 209b is located directly above the ground film 203, that is, the soil discharged from the discharge port 209b falls on the ground film 203, and then under the rolling of the rolling roller 208, the soil covers the ground film 203, thereby enhancing the firmness of the ground film 203 and preventing the ground film 203 from being blown away by external wind and causing the ground film 203 to separate from the saline-alkali land 1.
