Description

Technical Field

[0001] This utility model relates to a buckwheat cultivation device, specifically a variable-spacing buckwheat precision cultivation device, belonging to the field of agricultural planting technology. Background Technology

[0002] Buckwheat belongs to the Polygonaceae family and the Fagopyrum genus. It is an annual dicotyledonous herbaceous plant that is rich in nutrients, has high medicinal value, and has great development potential. The protein, fat, vitamin, and trace element content of its grains is higher than that of major grain crops such as rice, wheat, and corn. It also contains chlorophyll and rutin, which are not found in other cereal grains. In order to improve the survival rate of buckwheat and reduce the waste of buckwheat seeds, buckwheat planting has gradually shifted from sowing to buckwheat seedling cultivation. At this time, cultivation equipment is needed to carry out precise cultivation of buckwheat.

[0003] Existing buckwheat cultivation equipment cannot precisely adjust the spacing between buckwheat seedlings according to different planting environments and requirements. This results in buckwheat seedlings being planted too densely or too sparsely, leading to reduced yields due to their inability to adapt to the planting environment. Consequently, the equipment's adaptability to buckwheat seedling cultivation is compromised. Therefore, this paper proposes a variable spacing buckwheat precision cultivation device.

Two first limiting rings 213 are fixedly connected to the outer surface of the wheel frame 201. The opposite sides of the two first limiting rings 213 are in contact with the outer surface of the belt 203. The first limiting rings 213 can limit the position of the belt 203 on the wheel frame 201 and prevent the belt 203 from deviating from the wheel frame 201.

[0016] Please refer to this carefully. Figure 2 and Figure 4 The input end of the gear manual transmission 202 is connected to the belt 203 via a pulley.

[0017] Please refer to this carefully. Figure 2 and Figure 4 A first bevel gear 205 is fixedly connected to the outer surface of the drive shaft 204. A hopper 206 is provided above the fixed frame 1. A fixed cylinder 207 is fixedly connected to one side of the hopper 206. Several buckwheat seedlings 208 are provided inside the hopper 206. A positioning frame 215 is rotatably connected to the outer surface of the drive shaft 204. The bottom surface of the positioning frame 215 is fixedly connected to the upper surface of the fixed frame 1. The positioning frame 215 can increase the rotation reliability and stability of the drive shaft 204 without affecting the rotation of the drive shaft 204.

[0018] Please refer to this carefully. Figure 2 and Figure 4 The fixed cylinder 207 is rotatably connected to a rotating frame 209. The inner wall of the rotating frame 209 is fixedly connected to four limiting cylinders 210. The bottom surface of the fixed cylinder 207 is provided with a discharge port 211. The bottom end of the rotating frame 209 is fixedly connected to a second bevel gear 212, which meshes with the first bevel gear 205. The upper surface of the fixed frame 1 is fixedly connected to two support frames 216. The upper surfaces of the two support frames 216 are fixedly connected to the bottom surface of the hopper 206. The support frames 216 can support the hopper 206, keep the hopper 206 at a suitable tilt angle, and increase the stability of the connection between the hopper 206 and the fixed frame 1.

[0019] Please refer to this carefully. Figure 2 and Figure 3An auxiliary component 3 is provided below the fixed frame 1. The auxiliary component 3 includes a furrowing plow 301, the upper surface of which is fixedly connected to the bottom surface of the fixed frame 1. Two soil covering wheels 302 are fixedly connected to the bottom surface of the fixed frame 1. A limit frame 303 is fixedly connected to the upper surface of the fixed frame 1. A connecting rod 304 is slidably connected inside the limit frame 303. A rolling wheel 305 is fixedly connected to the bottom end of the connecting rod 304. The outer surface of the rolling wheel 305 contacts the outer surface of the belt 203. A compression spring 306 is sleeved on the outer surface of the connecting rod 304. The top end of the compression spring 306 is fixedly connected to the inner top wall of the limit frame 303, and the bottom end of the compression spring 306 is fixed to the upper surface of the rolling wheel 305. The connection is achieved by using a furrowing plow 301 to create furrows in the soil, facilitating the subsequent planting of buckwheat seedlings 208. The inclined metal wheel in the soil covering frame 302 allows the soil plowed by the furrowing plow 301 to be gathered back together during the movement of the fixed frame 1, ensuring the proper covering of the buckwheat seedlings 208 after planting. Finally, the elastic force provided by the compression spring 306, in conjunction with the limiting frame 303 and connecting rod 304, provides downward pressure to the rolling wheel 305. This, combined with the rotation of the rolling wheel 305, provides tension to the belt 203 without affecting its rotation, ensuring stable power transmission between the wheel frame 201 and the manual gear transmission 202.

[0020] When using this utility model: First, the fixing frame 1 is assembled with the tractor via the rear trailer that comes with the tractor. Then, the buckwheat seedlings 208 with seedling soil after seedling cultivation are placed into the hopper 206. As the tractor pulls the fixing frame 1 to move, the furrowing plow 301 can plow furrows in the land, which is convenient for the subsequent cultivation and planting of buckwheat seedlings 208. When the fixed frame 1 moves, the wheel frame 201 will rotate as it contacts the ground. This rotation, via the belt 203 and the first and second limit rings 213 and 214, drives the internal gear structure of the manual gear transmission 202 to rotate. Power is then transmitted to the rotating frame 209 via the drive shaft 204 and the first and second bevel gears 205 and 212. As the rotating frame 209 rotates, it drives multiple limit cylinders 210 to rotate within the fixed cylinder 207. At this time, the hopper 206 has a certain angle of inclination. Therefore, the buckwheat seedlings 208 located inside the hopper 206 can automatically slide towards the fixed cylinder 207 and enter the limiting cylinder 210 through the opening of the limiting cylinder 210. When the limiting cylinder 210 rotates to be perpendicular to the discharge port 211, the buckwheat seedlings 208 can fall downwards into the furrow plow 301 due to gravity. Through the metal wheel with an inclined angle in the soil covering frame wheel 302, the soil plowed by the furrow plow 301 can be gathered again during the movement of the fixed frame 1, ensuring that the soil covering work after the buckwheat seedlings 208 are planted can proceed normally. When it is necessary to adjust the spacing between buckwheat seedlings 208 according to the planting environment and planting needs, simply use the handle on the manual gearbox 202 in conjunction with the gear set inside the manual gearbox 202 to switch to different power transmission ratios. This allows the transmission ratio between the wheel frame 201 and the drive shaft 204 to be changed while maintaining the same speed, causing the rotating frame 209 to rotate faster or slower. When the rotating frame 209 rotates faster, the limiting cylinder 210 also rotates faster, thus changing the frequency at which the buckwheat seedlings 208 fall over the same distance. The height of the rotating frame 209 can shorten the spacing between the buckwheat seedlings 208, while the slower rotation of the rotating frame 209 reduces the frequency of the falling buckwheat seedlings 208, thus increasing the spacing between the buckwheat seedlings 208. This allows for precise adjustment of the spacing between the buckwheat seedlings 208, facilitating timely switching of the spacing between the seedlings 208 according to different planting environments and requirements. This prevents the buckwheat seedlings 208 from being too dense or too sparse during cultivation, thus increasing the adaptability of the buckwheat cultivation equipment to different environmental conditions. Furthermore, the elastic force provided by the compression spring 306, in conjunction with the limit bracket 303 and the connecting rod 304, can provide downward pressure to the rolling wheel 305. At this time, in conjunction with the rotation of the rolling wheel 305, it can provide tension to the belt 203 without affecting the rotation of the belt 203, thus ensuring the stable transmission of power between the wheel frame 201 and the gear manual transmission 202.
