Description

Technical Field

[0001] The invention relates to the technical field of sowing equipment, in particular to a saline-alkali land micro-soil pelletized seed sowing equipment. Background Art

[0002] Micro-guest soil technology is a alkali treatment technology, which consists of stress-resistant seeds, trace amounts of soil, nutrients, water retaining agents, adhesives, and supports. Organic matter is added to the micro-guest soil, followed by metal complex ions, fertilizers, and finally adhesives to form pellets. Salt-alkali-tolerant pioneer plant varieties are selected and placed in the pellets, which are buried in the soil, and water is accumulated in the cofferdam to allow the seeds to germinate. This technology is used to restore vegetation in saline-alkali land. It is difficult for pioneer plant seeds to survive directly in saline-alkali land, and the germination rate is very low. Using micro-guest soil technology to bury the seeds in pellets and plant them in saline-alkali land can greatly improve their germination rate and survival rate.

[0003] Existing seed sowing equipment has the following defects: First, there are strict restrictions on the applicability of seeds, and there are high standard requirements for seed size, shape, density and even germination rate. Once the seeds fail to meet these stringent conditions, it may directly affect the final effect of sowing, resulting in uneven sowing, and then affecting the subsequent crop growth and yield. This high sensitivity to seed characteristics undoubtedly increases the difficulty and cost of farmers in seed selection and pretreatment; Second, although the highly modernized sowing machinery has shown significant advantages in improving sowing speed and accuracy, its high initial purchase cost has become an insurmountable threshold for many farmers. In addition, these high-end equipment often require regular professional maintenance and maintenance to ensure its continued efficient operation. This series of subsequent expenses has undoubtedly further increased the economic pressure on farmers and limited the popularization and application of advanced sowing technology in a wider range; Third, the existing sowing equipment is insufficient in the precise control of the sowing amount. This lack of fine regulation often leads to excessive consumption and waste of seeds during use, which not only increases agricultural production costs, but also causes unnecessary loss of resources. Summary of the invention

[0004] The object of the present invention is to provide a saline-alkali land micro-soil pelletized seed sowing equipment to solve the problems raised in the above background technology.

[0010] As a further technical solution of the present invention, an auxiliary pipe is conductively connected to the outer wall of one side of the mixing piston tube, and a second fixing frame is fixedly connected to the upper surface of the frame.

[0011] As a further technical solution of the present invention, a third telescopic cylinder is fixedly connected to an outer wall of one side of the second fixed frame, an output end of the third telescopic cylinder is fixedly connected to an auxiliary piston, and the auxiliary piston is sleeved in the auxiliary pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is designed with a new seed embedding and seed arrangement structure, and the micro-soil is pushed into the seed storage box by a piston to stick the seeds, which greatly reduces the requirements for seed characteristics. Compared with traditional air-suction seeders and no-till seeders, it is no longer limited by conditions such as seed size, shape, density and germination rate, thereby ensuring that the seeds can be evenly and appropriately embedded. This optimized embedding method not only provides an ideal germination environment for the seeds, but also significantly improves the germination rate of the seeds, effectively reduces the seed loss problem caused by improper embedding, and has higher stability and Reliability, and the overall structural design is relatively simple, avoiding unnecessary complex components, thus achieving lower production costs. This advantage not only reduces the initial purchase investment, but also makes subsequent maintenance and maintenance work easier and faster, greatly reducing the economic burden, and is conducive to the market popularization of seed drills. At the same time, the use of slide structure and piston structure realizes the smooth connection between the sticky seed embedding and the drop material sowing process. The use of slide vane cutting micro-soil mixture for drop material sowing not only ensures the uniformity and moderation of seeds in the embedding process, but also realizes the precise control of the sowing amount, further reducing the seed waste rate.

An auxiliary piston 18 is provided, and the auxiliary piston 18 is sleeved in the auxiliary tube 19. The third telescopic cylinder 21 and the auxiliary piston 18 are used to realize the step of micro-soil adhering seeds; a through hole is opened at the position of the mixing piston tube 4 on the upper surface of the frame 1, and the through hole is used for dropping and sowing; fixed brackets 29 are fixedly connected to the outer walls on both sides of the frame 1, and a pressing wheel 3 is rotatably connected to the fixed bracket 29, and the pressing wheel 3 is used to cover the ditch filled with pelletized seeds with soil, press and film; a fixed plate 28 is fixedly connected to the lower surface of the frame 1, and a trenching shovel 2 is fixedly connected to one end of the fixed plate 28. The trenching shovel 2 is used for digging ditches in saline-alkali land to prepare for subsequent sowing.

[0027] Working principle: When the present invention is used for sowing pelletized seeds in saline-alkali land, micro-soil is first prepared. The micro-soil is selected by weight. The pH value of the micro-soil can be neutral or slightly acidic (pH value is 4.5-6.5), adding organic matter to the micro-soil, the organic matter can be grass clippings or leaves, the ratio of organic matter to micro-soil is 150-200g:8-10kg, preferably 200g:10kg, adding metal complex ions, the metal complex ions are a mixture of one or more of Fe, Cu, Mn, Zn, Co and EDTA-Na2 complex ions, mixing with fertilizer, the fertilizer is one, two or three of N fertilizer, P fertilizer, K fertilizer, adding adhesive to form granules, the adhesive can be starch or flour, the ratio of adhesive to micro-soil is 300-350g:15-20kg, preferably 350g:20kg, mixing the micro-soil, organic matter, metal complex ions, fertilizer The mixture is mixed with the adhesive to form a uniform mixture, and then the prepared micro-soil is added to the micro-soil storage box 5. When sowing begins, the frame 1 is driven forward by the front of the vehicle, and ditches are dug on the saline-alkali land using the trenching shovel 2 on the fixed plate 28 to prepare for sowing. During the forward movement, the micro-soil is adhered to the seeds. The first telescopic cylinder 7 on the first fixed frame 15 drives the slide 8 to reciprocate along the slide rail 9. When the seed-adhering hole 11 on the slide 8 is aligned with the bottom opening of the mixing piston tube 4 on the fifth fixed frame 24, the third telescopic cylinder 21 on the second fixed frame 16 drives the auxiliary piston 18 to move inward in the auxiliary tube 19. Under the squeezing action of the auxiliary piston 18, part of the micro-soil in the mixing piston tube 4 passes through the seed-adhering hole 11 enters the seed storage box 6 to adhere the seeds. After the adhesion is completed, the third telescopic cylinder 21 drives the auxiliary piston 18 to reset. Under the action of negative pressure, the micro-soil adhering to the seeds returns to the mixing piston tube 4 to form a mixture. The micro-soil wraps the seeds so that the seeds are completely wrapped by the micro-soil to form pellets. Then, when the slide 8 moves to the point where the drop hole 10 is aligned with the bottom opening of the mixing piston tube 4, the second telescopic cylinder 20 on the fourth fixed frame 23 pushes the main piston 17 downward in the mixing piston tube 4. The micro-soil wrapped with seeds in the mixing piston tube 4 passes through the drop hole 10 under the extrusion of the piston assembly. When the first telescopic cylinder 7 drives the slide 8 to continue to reciprocate, the drop hole 10 on it is staggered with the bottom opening of the mixing piston tube 4. The sealing part 12 on the sheet 8 cuts the micro-soil mixture passing through the drop hole 10 during the process of closing the bottom opening of the mixing piston tube 4, causing it to fall into the ditch to form pelletized seeds. When the main piston 17 is reset, the micro-soil storage box 5 replenishes the mixing piston tube 4 with micro-soil through the connecting pipe 25 and the one-way valve 14. When the bottom opening of the mixing piston tube 4 is closed, the seed sticking hole 11 on the slide 8 is aligned with the discharge port 26 on the seed replenishment box 13, and the seeds in the seed replenishment box 13 on the third fixed frame 22 flow into the seed storage box 6 to form seed replenishment. Finally, during the movement of the frame 1, the pressing wheel 3 on the tail end fixed bracket 29 covers the ditch filled with pelletized seeds with soil, pressing and filming to complete the sowing process.
