Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, specifically to a rice hole-sowing seeder. Background Technology

[0002] Traditionally, rice is mostly planted using two methods: row sowing and hill sowing.

[0003] Rice row sowing refers to scattering rice seeds evenly on the paddy field, then burying them in the soil with a hoe or plow, and covering them with a thin layer of soil so that the seeds can germinate and grow smoothly; while rice hole sowing involves digging a small hole in the paddy field, placing the seeds in the hole, and then covering the seeds with soil so that the seeds can contact the soil and grow smoothly.

[0004] Rice hill-planting has advantages such as concentrated fertilization and uniform seedling emergence, but it also has disadvantages such as high labor costs and reduced yield. With the development of agricultural mechanization, rice mechanical hill-planting technology has been gradually promoted and applied, effectively improving sowing efficiency. Traditional hill-planting devices mostly use wheels to create ridges. Ridging is done by inserting a plow into the soil and using animal or mechanical power to pull the plow to create a furrow, forming a ridge between the furrows. Then, holes are made and seeds are placed in the ridge. Traditional hill-planting machines are expensive and have complex structures, resulting in high costs that have prevented some small individual farmers from using them. Utility Model Content

[0005] The main purpose of this application is to provide a rice hill-planting machine that aims to solve the aforementioned technical problems.

[0035] See attached document Figure 1 This application provides a rice hill-sowing machine, including a plow plate 1 and several hill-sowing components 4 disposed on the plow plate 1. A handrail frame 2 is welded to the surface of the plow plate 1 on one side of its head. Multiple rope buckles 3 are disposed on the handrail frame 2. The rope buckles 3 are used to connect the pull ropes. The pull ropes connect the plow plate 1 to animal power or mechanical power, so that the worker can stand and hold the handrail frame 2 or sit on the plow plate 1 and move the plow plate 1 by animal power or mechanical power. The front end of the flat plate is raised, which can play an obstacle-crossing role when encountering raised soil. In addition, because the contact area between the plow plate 1 and the ground is large, it can support the weight on it. Moreover, the weight of the worker can also make the plow plate 1 have a certain downward pressure, so that the soil is leveled during movement, which facilitates hill sowing.

[0036] Continue as Figure 1 As shown, the hill-planting component 4 includes a pointed cylinder 41 and a hopper 43. The pointed cylinder 41 is mounted on the plow plate 1 via a lifting mounting frame and can complete a vertical lifting movement perpendicular to the plow plate 1 under the drive of the lifting mounting frame. The pointed cylinder 41 is provided with a feeding channel 411 along its axis, so that the pointed cylinder 41 moves downward to open up a planting hole and the rice seeds are inserted into the planting hole through the feeding channel 411 to complete the hill-planting.

[0037] In the above, such as Figure 2 and Figure 3As shown, the hopper 43 is fixedly welded to the top of the pointed cylinder 41, and the bottom of the hopper 43 is provided with a discharge port 44 that communicates with the feeding channel 411. The pointed cylinder 41 is provided with a slot in the horizontal direction near the discharge port 44. A baffle plate 42 is provided in the slot. The baffle plate 42 can move laterally in the slot. The baffle plate 42 is provided with a discharge port 423. In the natural state, the discharge port 423 is misaligned with the discharge port 44, so that no material can be discharged in the natural state. When the pointed cylinder 41 moves downward, the baffle plate 42 is moved into the slot by external force, so that the discharge port 423 and the discharge port 44 are aligned, so that rice seeds enter the feeding channel 411 from the hopper 43 through the discharge port 44 and the discharge port 423.

[0038] In a preferred embodiment, to achieve the intermittent up-and-down reciprocating motion of the pointed cylinder 41, such as... Figure 1 As shown, the lifting mounting frame includes a smooth shaft 10, a lead screw shaft 11, a crossbar 15, a motor 7, a driving bevel gear 8, and a driven bevel gear 9. Two bushings are mounted on the plow plate 1. The smooth shaft 10 is fixedly installed in one bushing, while the lead screw shaft 11 is rotatably installed in the other bushing via a bearing. The crossbar 15 is positioned between the smooth shaft 10 and the lead screw shaft 11. One end of the crossbar 15 has a threaded bushing that mates with the lead screw shaft 11, and the other end has a smooth bushing that slides with the smooth shaft 10. The crossbar 15 has several breaks spaced along its length, and pointed cylinders 41 are welded to each break. The motor 7 is fixedly mounted on the plow plate 1, and its output end has a driving bevel gear 8. The driven bevel gear 9 is fixedly fitted onto the lead screw shaft 11, and the driving bevel gear 8 and the driven bevel gear 9 remain meshed.

[0039] In the above embodiment, the forward and reverse rotation of the motor 7 drives the driving bevel gear 8 and the driven bevel gear 9 to rotate, causing the lead screw shaft 11 to rotate. The rotation of the lead screw shaft 11 causes the pointed cylinder 41 to reciprocate up and down along with the crossbar 15 under the guidance of the lead screw shaft 11 and the guide shaft 10. Of course, the pointed cylinder 41 is at a certain distance from the ground, allowing it to complete the opening of holes at equal intervals. Simultaneously, to ensure that the pointed cylinder 41 can pass smoothly through the plow plate 1, a clearance hole 14 is provided below the pointed cylinder 41 on the plow plate 1.

[0040] Understandably, in order to provide power 13 to the motor 7, a power supply box 13 is also provided on the plow plate 1. The power supply box 13 contains a power supply module 13 for supplying power to the motor 7. The power supply box 13 also protects the power supply module 13 from water immersion. In this embodiment, the motor 7 can be a DC geared motor 7, which can achieve forward and reverse rotation through a dual-capacitor preset forward and reverse function. The power supply module 13 can be a Chint NKY1-S-200 power supply module 13, with multiple power supply output specifications available.

[0041] Of course, the driving and driven bevel gears can be housed in a single gearbox for protection, preventing accidents. For example... Figure 4 As shown, the gearbox has an open bottom design, which is welded to the plow plate 1 to hold the bushing. The gearbox also has two shaft holes for mounting the motor shaft and the lead screw shaft.

[0042] In a preferred embodiment, in order to achieve simultaneous hole opening and sowing, such as Figures 1 to 3 As shown, the baffle plate 42 includes a main body plate and a first wedge plate 421. The main body plate is slidably inserted into the slot. The first wedge plate 421 is integrally formed on the end of the main body plate located outside the slot. A spring 422 is fixedly installed on the bottom side of the first wedge plate 421 facing the pointed cylinder 41. The spring 422 extends to be fixedly welded to the outer wall of the pointed cylinder 41. On the parallel side of the lifting mounting frame, a bracket 5 is welded to the plow plate 1. Several second wedge plates 6 are installed on the bracket 5. The first wedge plate 421 and the second wedge plate 6 correspond one-to-one and their inclined surfaces are adapted.

[0043] As can be imagined, when motor 7 rotates forward, the pointed cylinder 41 moves downward. During this downward movement, the first wedge plate 421 contacts the second wedge plate 6, and the second wedge plate 6 applies pressure to the first wedge plate 421, pushing it inward. The spring 422 is compressed. When the pointed cylinder 41 moves downward to its lowest point, the feed port 423 aligns with the discharge port 44, thus completing the opening of the hole and achieving sowing simultaneously. When motor 7 reverses, the pointed cylinder 41 gradually moves upward, and under the action of spring 422, the first wedge plate 421 is ejected outward, causing the feed port 423 and discharge port 44 to misalign, stopping the feeding and sowing. Thus, with the continuous forward and reverse rotation of motor 7, the opening of the hole and sowing are completed.

[0044] It should be noted that the accompanying drawings of this embodiment only show three hole-planting components 4, but the number of hole-planting components 4 is not limited.

[0045] Furthermore, in a preferred embodiment, such as Figure 1 The plow plate 1 is equipped with a ridging harrow 12 at its tail end. The ridging harrow 12 extends downward beyond the bottom surface of the plow plate 1 by a certain length. When the plow plate 1 is driven by animal power or mechanical power, the ridging harrow 12 forms two furrows to achieve the function of ditching.

[0046] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
