Corrugated disc ditching drill seeder for saline-alkali soil wheat fertilization

Abstract

The utility model relates to a corrugated disc ditching drill seeder for wheat fertilization in saline-alkali soil. The corrugated disc ditching drill seeder comprises a beam frame and a ditching piece, the ditching piece comprises a machine shell, a support and a corrugated disc. When the beam frame advances, the corrugated disc is used as a core ditching component to firstly contact with soil. The surface corrugated structure obviously increases friction force with soil, and the problem that a traditional disc slips in non-thawed saline-alkali soil is solved. The corrugated cutting edge of the corrugated disc cuts into a hard hardened layer through the shearing effect, and the fertilizer is conveyed to the bottom of the deep groove through the fertilizing pipe. Wherein the two ditching discs are arranged in a V shape, the shape of a ditch wall is continuously tidied, continuous and straight ditches are ensured, and intermittent fertilization caused by bounce of a common disc is avoided. The soil covering pinch roller completes operation closed loop following fertilization, and the pinch roller synchronously compacts surface soil when rolling.

Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and is particularly applicable to deep fertilization operations in unthawed soil during wheat planting in saline-alkali land. Specifically, it is a wheat fertilization strip seeder based on a corrugated disc furrow opener. Background Technology

[0002] In wheat cultivation, fertilization is crucial for ensuring wheat yield and quality. Existing conventional wheat fertilizer applicators mostly use disc furrow openers; however, this traditional design has revealed several shortcomings in practice. Firstly, the smooth surface of the disc opener makes it prone to slipping in unthawed saline-alkali soil, resulting in inconsistent furrow depth, typically only 3-5 cm. Such shallow fertilization makes it difficult for fertilizer to reach the wheat root system's absorption layer, hindering nutrient absorption. Furthermore, shallow fertilization leads to fertilizer volatilization or runoff with water. Especially in saline-alkali soil, soil compaction further impedes fertilizer absorption, reducing fertilizer utilization. To ensure wheat growth, farmers often need to increase the amount and frequency of fertilization, undoubtedly increasing agricultural production costs. Secondly, ordinary disc furrow openers tend to bounce in hard soil, failing to guarantee furrow continuity. Therefore, there is an urgent need for a corrugated disc furrow opener and row seeder for deep fertilization operations in unthawed saline-alkali soil. Utility Model Content

[0003] The main purpose of this utility model is to provide a corrugated disc furrowing and striping machine for wheat fertilization in saline-alkali land, so as to solve the problem in the prior art where the disc furrower is prone to slipping in unthawed saline-alkali land due to the smooth surface of the disc, resulting in unstable furrowing depth.

[0004] To achieve the above objectives, this utility model provides a corrugated disc furrowing seeder for wheat fertilization in saline-alkali land, including a beam frame and furrowing components;

[0005] Grooved components, including housing, brackets, and corrugated discs;

[0006] One end of the bracket is fixedly connected to the beam frame, and the other end is connected to the machine casing and the corrugated plate respectively;

[0007] The tail of the casing is equipped with a soil-covering roller, and two trenching discs are fixed in the middle.

[0008] One end of the two trenching discs is in contact with each other, and the other end has a receiving space;

[0009] The fertilizer application pipe is fixed on the machine casing, and the outlet of the fertilizer application pipe is located within the receiving space;

[0010] The soil-covering roller, trenching disc, and corrugated disc are arranged in sequence.

[0012] Preferably, the angle between each trenching disc and the direction of travel is 15°-35°.

[0013] Preferably, a scraper is fixed at the angle between the two trenching discs to prevent blockage by wet, sticky soil, and the outlet of the fertilizer pipe is located on one side of the scraper.

[0014] Preferably, the soil covering roller is a double rubber roller, and the roller spacing is adapted to the trench width.

[0015] Preferably, the support includes an inclined rod, a pressing rod, and an inclined bar;

[0016] One end of the tilting rod is connected to the rear of the machine casing, and the other end is fixedly connected to the horizontally set beam frame;

[0017] One end of the inclined pressing rod is fixedly connected to the machine housing, and a limiting protrusion is fixedly installed on the pressing rod and a spring is sleeved on it;

[0018] One end of the spring abuts against the limiting protrusion, and the other end is fixedly connected to the beam frame;

[0019] One end of the inclined rod is fixedly connected to the beam frame, and the other end is rotatably fitted with a corrugated disc.

[0020] Preferably, the angle between the inclined rod and the horizontal beam is between 15° and 35°.

[0021] Preferably, the corrugated disc furrow seeder for fertilizing wheat in saline-alkali land also includes a body and a hopper;

[0025] The beneficial effects of the above scheme are:

[0026] As the beams move forward, the corrugated discs, as the core trenching component, are the first to contact the soil. Their corrugated surface structure significantly increases friction with the soil, overcoming the slippage problem of traditional discs on unthawed saline-alkali land. The corrugated discs' wave-shaped cutting edges cut into the hardened, compacted layer through shearing action, and fertilizer is delivered to the bottom of the deep trench through the fertilizer pipe. Two trenching discs are arranged in a V-shape, continuously shaping the trench walls to ensure a continuous and straight trench, avoiding the intermittent fertilization caused by the bouncing of ordinary discs. The soil-covering rollers follow immediately after fertilization to complete the operation loop, simultaneously compacting the surface soil as the rollers roll. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0035] like Figures 1-4As shown, this embodiment provides a corrugated disc furrowing seeder for wheat fertilization in saline-alkali land, including a beam frame 10 and a furrowing component 20. The furrowing component 20 includes a housing 21, a support 22, and a corrugated disc 23. Figure 3 , Figure 4 As shown, the outer edge of the corrugated disc 23 is provided with continuous wavy teeth 230, the height of which is 8 mm-12 mm and the wave pitch is 30 mm-50 mm. One end of the support 22 is fixedly connected to the beam frame 10, and the other end of the support 22 is connected to the casing 21 and the corrugated disc 23 respectively. A soil-covering roller 24 is mounted at the rear of the casing 21, and two trenching discs 25 are fixed in the middle of the casing 21. The angle between each trenching disc 25 and the forward direction is 15°-35°. Figure 4 As shown, one end of the two trenching discs 25 is in contact with each other, and the other end of the two trenching discs 25 has a receiving space 250. A fertilizer pipe 26 is fixed to the casing 21, and the outlet of the fertilizer pipe 26 is located within the receiving space 250. The soil covering roller 24, trenching discs 25, and corrugated discs 23 are arranged in sequence. The soil covering roller 24 is a double rubber roller, and the wheel spacing of the soil covering roller 24 is adapted to the trench width. The soil covering roller 24 closely follows the trenching discs 25 to achieve soil compaction in the trenches and reduce fertilizer exposure.

[0036] As the beam frame 10 moves forward, the corrugated disc 23, as the core trenching component, first contacts the soil. Its corrugated surface structure significantly increases friction with the soil, overcoming the slippage problem of traditional discs in unthawed saline-alkali soil. The corrugated cutting edge of the disc 23 cuts into the hard, compacted layer through shearing action, and fertilizer is delivered to the bottom of the deep trench through the fertilizer application pipe 26. Two trenching discs 25 are arranged in a V-shape, continuously shaping the trench walls to ensure a continuous and straight trench, avoiding the intermittent fertilization caused by the bouncing of ordinary discs. The soil compaction roller 24 follows immediately after fertilization to complete the operation loop, simultaneously compacting the surface soil as it rolls.

[0037] like Figure 3 , Figure 4As shown, a scraper 30 is fixed at the angle between the two trenching discs 25 to prevent clogging by wet, sticky soil. The outlet of the fertilizer pipe 26 is located on one side of the scraper 30. The support 22 includes an inclined rod 220, a pressing rod 221, and an inclined bar 222. One end of the inclined rod 220 is connected to the tail of the housing 21, and the other end of the inclined rod 220 is fixedly connected to the horizontally arranged beam frame 10. One end of the inclined pressing rod 221 is fixedly connected to the housing 21, a limiting protrusion 223 is fixedly provided on the pressing rod 221, and a spring 224 is sleeved on the pressing rod 221. One end of the spring 224 abuts against the limiting protrusion 223, and the other end of the spring 224 is fixedly connected to the beam frame 10. One end of the inclined bar 222 is fixedly connected to the beam frame 10, and a corrugated disc 23 is rotatably mounted on the other end of the inclined bar 222. The angle between the inclined rod 222 and the horizontally positioned beam 10 ranges from 15° to 35°. The corrugated disc 23 can be 400mm in diameter, with a corrugated tooth height of 10mm and an installation angle of 25°. During operation, the existing hydraulic pressurization mechanism applies a vertical pressure of 200N to stabilize the trench depth at 10cm. After the fertilizer falls into the trench bottom through the fertilizer application pipe, the soil compaction roller 24 compacts it with a 5cm soil layer to ensure full contact between the fertilizer and the soil.

[0038] The corrugated disc furrow seeder for wheat fertilization in saline-alkali land also includes a vehicle body (not shown) and a hopper (not shown). The beam frame 10 is connected to the vehicle body via a lifting mechanism (not shown) and is located at the rear of the vehicle body. The lifting mechanism uses existing technology and will not be described in detail; it simply needs to be able to adjust the height of the beam frame 10. The hopper is fixedly connected to the top of the beam frame 10, and both are located above the furrowing component 20. The soil-covering roller 24, two furrowing discs 25, and corrugated disc 23 are arranged sequentially and gradually approach the vehicle body. The hopper is connected to the feed inlet of the fertilizer pipe 26 via a flexible pipe.

[0039] Additionally, the beam frame 10 includes a first square tube 11, a second square tube 12, and a connecting tube 13. There are two first square tubes 11, two second square tubes 12, and two connecting tubes 13, arranged along the width direction of the vehicle body. The two connecting tubes 13 pass sequentially through the two first square tubes 11 and the two second square tubes 12, and are fixedly connected to them. Each first square tube 11 has multiple grooved members 20 spaced at intervals along its length. The grooved members 20 on one first square tube 11 are staggered with those on another. One end of each inclined rod 220 and diagonal rod 222 is located on a first square tube 11. Each second square tube 12 has multiple springs 224 fixedly installed along its length. The springs 224 on one second square tube 12 are staggered with those on another, and each spring 224 corresponds one-to-one with each inclined rod 220. The setting of multiple trenching components 20 enables multiple trenching and fertilization processes to be carried out simultaneously.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
