Description

Technical Field

[0001] The invention relates to the technical field of oat sowing equipment, in particular to a compound seeder for improving saline-alkali land with oats and a land improvement method thereof. Background Art

[0002] Oats are annual herbaceous plants of the Poaceae family and the genus Avena. They are mostly cultivated in Northeast my country, North China, Northwest China, Southwest China, Guangdong, Guangxi and Central China. Oats like coolness, moisture and sunlight, but are not resistant to high temperatures. Insufficient light will cause stunted development. They are generally sown and planted in cold and dry areas such as plains, flat land, beams and gently sloping land in mountainous areas. Oats have a significant effect in lowering low-density cholesterol and a certain effect in increasing serum high-density cholesterol. The lipid-lowering effect is very obvious. Oats have a strong salt-alkali resistance and can grow in soils with a pH value below 9.5 and a total salt content below 4%. Their salt-alkali resistance makes them an ideal crop for improving saline-alkali land. By planting oats, the surface cover is increased and some salt ions are absorbed, thereby reducing the pH value and total salt content in the soil.

[0003] Most of the existing oat sowing equipment can only sow oats under normal conditions. When oats are sown in saline-alkali areas covered with a saline-alkali layer on the surface, traditional oat sowing equipment cannot adapt to the land environment, which affects the survival rate of oats after planting and has limitations in use. Summary of the invention

[0004] The invention discloses a compound seeder for improving saline-alkali land with oats and a land improvement method thereof, aiming to solve the technical problem that most existing oat sowing equipment can only sow oats under conventional conditions and has usage limitations.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The other end of the frame is also provided with a seed placement mechanism for placing oat seeds, the seed placement mechanism includes a seed placement box fixed to one end of the top of the frame, the seed placement box is horizontally distributed on the side of the feeding box, and a second rotating shaft is rotatably installed inside the seed placement box;

[0008] A conveying mechanism for controlling the amount of material discharge is provided at the bottom of the material discharge mechanism and the seed placement mechanism, and the conveying mechanism includes a base plate vertically distributed at the bottom of the seed placement box, and a hydraulic rod is fixedly installed between the end of the base plate and the seed placement box;

[0009] A tillage mechanism for digging channels and burying seeds is provided at the bottom of the conveying mechanism;

[0010] The feeding mechanism and the seeding mechanism introduce the improver and oat seeds into the interior of the tillage mechanism through the conveying mechanism, and complete the canal opening, improvement and sowing of the saline-alkali land through the tillage mechanism.

[0011] By arranging a feeding mechanism and a planting mechanism on the top of the frame, the pre-prepared oat seeds and improvers are introduced into the interior of the tillage mechanism through the conveying mechanism, and the frame is used to drive the tillage mechanism to move along the fields. The tillage mechanism will dig deep ditches in the fields and introduce the seeds and improvers into the ditches together. The improvers surround the oat seeds to provide a favorable environment for the growth of the seeds. At the same time, the improvers can improve the salinity of alkaline fields to ensure the functionality of this equipment.

[0012] In a preferred solution, the unloading mechanism also includes a plurality of evenly distributed first material control parts fixedly sleeved on the outer side of the first rotating shaft, the first material control parts are distributed inside the unloading box, and a second motor is horizontally fixed on the outer side of the frame; the output end of the second motor is horizontally connected to the end of the first rotating shaft.

[0013] By arranging a feed box loaded with improver on the top of the frame, the second motor is used to drive the first rotating shaft to rotate, and the rotating first rotating shaft will synchronously drive the first material control part to rotate synchronously, so that the improver located inside the feed box is quantitatively transported to the interior of the tillage mechanism, thereby ensuring the integrity of the operation of the equipment.

[0014] In a preferred solution, the seed placement mechanism further includes a plurality of evenly distributed second material control members sleeved and fixed on the outer side of the second rotating shaft, and the second material control members are distributed inside the seed placement box.

[0015] By arranging a seed box loaded with oat seeds on the side of the discharge box, the rotation of the first rotating shaft is used to synchronously drive the second rotating shaft, and the rotating second rotating shaft will synchronously drive the second material control part to rotate, so that the oat seeds located inside the seed box are transported to the interior of the tillage mechanism in a quantitative manner, and the operation of the discharge mechanism is coordinated to complete the synchronous discharge of seeds and improvers, thereby further ensuring the integrity of the operation of this equipment.

[0016] In a preferred embodiment, the conveying mechanism also includes a plurality of evenly distributed telescopic tubes penetrating and connecting the top of the base plate and the interior of the seed box, a plurality of evenly distributed straight tubes penetrating and connecting the bottom of the base plate, the straight tubes and the telescopic tubes are penetrating and connected, and a rubber hose is penetrating and connected to the side of each straight tube, which is in turn penetrating and connected to the bottom of the seed box.

[0017] A base plate structure driven by a hydraulic rod is provided, and a tillage mechanism is installed at the bottom of the base plate. The vertically moving base plate is used to drive the tillage mechanism to move synchronously. At the same time, the top and bottom of the base plate are additionally equipped with telescopic tubes, straight tubes and hose structures. The seeds and improvers lowered by the feeding mechanism and the seeding mechanism can enter the interior of the tillage mechanism through these three respectively, and then be released to the field through the tillage mechanism, thereby ensuring the completeness of the operation of this equipment.

[0018] In a preferred embodiment, the tillage mechanism includes a plow fixedly mounted on the bottom of each straight tube, the plow having a feeding chamber and a seeding chamber formed therein, the feeding chamber and the interior of the hose being connected, the seeding chamber and the interior of the straight tube being connected, an auxiliary part being rotatably mounted inside the feeding chamber and the seeding chamber, and the stirring of the auxiliary part is used to assist the feeding of seeds and improvers.

[0019] By additionally equipping the bottom of the base plate with a specifically shaped plowshare structure, the base plate is moved vertically to drive the plowshare to move synchronously and insert into the saline-alkali land. At the same time, accompanied by the horizontal movement of the frame, the synchronously moving plowshare can open a deep V-shaped ditch in the saline-alkali land. Along with the operation of the feeding mechanism and the seeding mechanism, the lowered seeds and improvers can respectively pass through the seeding cavity and the feeding cavity inside the plowshare and fall into the ditch opened by the plowshare. On the one hand, the opened deep V-shaped ditch is utilized to assist the oat seeds in contact with the deep light soil of the saline-alkali land, thereby reducing the influence of salt and alkali on the oat seeds and ensuring the germination rate of the oat seeds. On the other hand, the lowered improver can be laid inside the deep V-shaped ditch to isolate the oat seeds from the saline-alkali land and maintain the salinity of the growth environment of the oat seeds. At the same time, the improver directly in contact with the saline-alkali land can reduce the salt-alkali content in the soil, thereby playing a role in improving the soil.

[0020] In a preferred embodiment, the auxiliary part includes a spherical paddle rotatably installed inside the feeding cavity and the seeding cavity, and a pushing member is distributed on the outside of the plow. At the same time, a connecting rod is fixedly connected between the spherical paddle and the pushing member, and the connecting rod runs through the side wall of the plow.

[0021] A spherical paddle structure driven by a pushing member is arranged inside the coulter, and when the coulter moves along the soil, the rotational force of the pushing member pushed by the friction of the soil is used to synchronously drive the spherical paddle to rotate. The rotating spherical paddle will move the improver and seeds inside the feeding cavity and the seeding cavity, thereby preventing blockage in the feeding cavity and the seeding cavity, thereby ensuring the integrity of the operation of the equipment.

[0022] As can be seen from the above, the compound seeder for improving saline-alkali land with oats and the land improvement method thereof provided by the present invention have the following improvements and advantages compared with the prior art:

[0023] First, by arranging a feeding mechanism and a seeding mechanism on the top of the frame, the pre-prepared oat seeds and improvers are placed inside the feeding box and the seeding box respectively, and the second motor is used to drive the first rotating shaft to rotate and transmit the second rotating shaft, thereby driving the first material control part and the second material control part to rotate synchronously, and the improver and oat seeds located inside the feeding box and the seeding box are quantitatively transported to the interior of the tillage mechanism, accompanied by an additional base plate structure, and the base plate that moves vertically is used to drive the tillage mechanism to move synchronously, and the telescopic tube, straight tube and hose structure additionally installed on the top and bottom of the base plate are used to introduce the improver and seeds into the deep layer of the saline-alkali land, so as to ensure the survival rate of the oat seeds and the integrity of the operation of the equipment.

[0024] Secondly, a specially shaped plowshare structure is additionally installed at the bottom of the base plate, and the base plate is moved vertically to drive the plowshare to move synchronously and be inserted into the saline-alkali land. Along with the horizontal movement of the frame, the synchronously moving plowshare can open a deep V-shaped ditch in the saline-alkali land, and the lowered seeds and improvers are respectively dropped into the ditch opened by the plowshare through the seed cavity and material cavity inside the plowshare. The deep V-shaped ditch is used to assist the oat seeds to contact with the deep light soil of the saline-alkali land, thereby reducing the influence of salt and alkali on the oat seeds and ensuring the germination rate of the oat seeds. The improver is laid inside the deep V-shaped ditch to isolate the oat seeds from the saline-alkali land and maintain the salinity of the growth environment of the oat seeds. At the same time, the improver directly in contact with the saline-alkali land can reduce the salt-alkali content in the soil, thereby improving the soil. Different from traditional oat planting equipment, this equipment can greatly improve the survival rate of oat seeds in saline-alkali land. At the same time, the equipment has the function of improving the saline-alkali soil environment and has the characteristics of multi-function and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
