Technical Field

[0001] The invention relates to the technical field of peanut sowing, in particular to an excavation seeder for planting peanuts in saline-alkali land. Background Art

[0002] Peanuts are one of the important economic crops, widely planted around the world. They not only provide high-quality plant protein and edible oil for humans, but also attract much attention for their important role in improving soil fertility. However, peanuts have high requirements for the growing environment, especially in saline-alkali conditions. The air permeability, salt drainage and planting depth accuracy of the soil will directly affect its germination rate and yield. In large-scale planting areas, peanut seeders are needed;

[0003] However, some existing peanut seeders are usually equipped with simple digging mechanisms and planting mechanisms. When planting seeds in saline-alkali land, the land needs to be loosened before planting the seeds. However, after loosening the land, the existing peanut seeders need to be manually or with additional machines to spread medicine to reduce the alkalinity of the land, thereby adding additional work tasks. After digging the holes and planting, other mechanisms are needed to backfill the soil, thereby increasing the cost of the equipment. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an excavation seeder for planting peanuts in saline-alkali land, which solves the problem that some existing peanut seeders need to loosen the land before planting seeds in saline-alkali land.

[0009] Preferably, the sowing mechanism includes two protective plates, the outside of the protective plates is rotatably connected to the inner wall of the sleeve, the inner wall of the protective plates is fixedly connected to two positioning rotating rods, the outside of the positioning rotating rods is fixedly connected to auxiliary gears, one end of the positioning rotating rod is rotatably connected to the inner wall of the sleeve, the outside of the connecting sleeve is fixedly connected to two racks, and the outside of the racks is meshingly connected to the outside of the two auxiliary gears.

[0010] Preferably, the loosening mechanism comprises a rotating shaft, both ends of which are rotatably connected to the inner wall of the supporting frame, the outside of the rotating shaft is fixedly connected to a plurality of fixed rings, and the outside of the fixed rings is fixedly connected to a plurality of loosening blocks.

[0014] Preferably, two telescopic rods are fixedly connected to the top of the support plate, and the bottoms of the telescopic rods are fixedly connected to the top of the connecting plate.

[0015] Preferably, the delivery pipeline is made of a hose, and a filter is installed at the port of the nozzle.

[0016] Working principle: When using this device, during the movement of the sowing vehicle, the loosening block is driven to loosen the soil, so that the rotating shaft and the fixed ring rotate on the inner wall of the support frame, loosening the soil and improving the air permeability. In this way, the connecting plate is driven up and down by starting the cylinder to adjust the sleeve box. At the same time, the telescopic rod provides auxiliary support, so that the connecting plate can move stably, adjust the sowing depth to adapt to different terrains, and effectively prevent the soil from affecting the internal structure;

[0017] When the box reaches a certain depth, the negative pressure generated by starting the air suction pump is used to suck the seeds from the storage box through the extraction pipe, and then transported to the inside of the connecting sleeve through the conveying pipe. In this way, the electric guide rail is started to drive the electric slider to move, thereby driving the connecting sleeve to be lifted vertically. In this way, through the meshing action of the rack and the auxiliary gear, and the rotation support provided by the positioning rotating rod, the two protective plates are rotated and opened. In this way, the external soil can be pushed by the rotation of the protective plates, thereby leaving a planting space inside, and the seeds are transported to the inside of the connecting sleeve in cooperation with the conveying mechanism. In this way, planting can be carried out conveniently, and the soil can be effectively prevented from affecting the bottom of the connecting sleeve. After the planting is completed, the two protective plates are merged, and the soil will cover the seeds due to a certain gravity.

[0018] After planting is completed, the motor drives the driving gear to rotate, thereby driving the driven gear to rotate. In this way, the scraper can be easily driven to rotate by connecting the rotating rod, so that the height of the scraper can be adjusted to meet the needs of different coverage heights. In this way, the medicine solution is extracted from the water tank by starting the pump body and transported to the nozzle through the water pipe. In this way, the soil environment of the saline-alkali land can be improved by spraying the medicine. The filter setting can effectively prevent impurities from clogging the nozzle to ensure smooth operation.

[0019] The present invention provides a digging seeder for planting peanuts in saline-alkali land. It has the following beneficial effects:

[0020] 1. The present invention realizes efficient seed transportation by utilizing an air suction pump, and drives the connecting sleeve to perform precise vertical lifting through an electric guide rail, and drives the opening and closing function of the protective plate through the cooperation of the rack and the auxiliary gear. After the planting is completed, the protective plates are merged to allow the soil to fall back and cover the seeds. This can effectively provide a stable planting space for the seeds, improve the sowing efficiency, ensure that the seeds can be evenly buried at an appropriate depth, and reduce the cost of manual intervention.

[0021] 2. The present invention starts the motor to drive the scraper to rotate, thereby adjusting the height, which is convenient for adjusting the seed coverage thickness, and draws the liquid from the water tank through the pump body and sprays it evenly on the surface of the saline-alkali soil. It not only achieves the leveling of the land after planting, but also improves the survival rate and yield of peanuts by improving the soil environment and preventing and controlling pests and diseases.

[0022] 3. The present invention loosens the soil effectively by driving the loosening block through the movement of the sowing vehicle body, and cooperates with the rotation of the rotating shaft and the fixed ring to loosen the soil, thereby improving the air permeability and soil structure of the saline-alkali land, creating a more suitable growth environment for sowing, and starting the cylinder to make the connecting plate drive the sleeve box to adjust, and cooperate with the lifting mechanism to flexibly adjust the sowing depth, thereby ensuring the adaptability of the equipment under different terrains and effectively avoiding the damage of the internal structure of the equipment to the soil.
