Technical Field

[0001] This utility model relates to the field of rapeseed planting technology, and more specifically, to an adjustable rapeseed planting and sowing device. Background Technology

[0002] Rapeseed planting and sowing equipment is an agricultural machine used for efficient and precise sowing of rapeseed. It usually consists of a seed box, seed metering device, furrow opener, and soil covering device. Its core function is to evenly sow rapeseed into the soil and control the sowing depth and spacing. It is suitable for row sowing or broadcast sowing. Modern models mostly adopt air suction or mechanical seed metering systems, and some are equipped with intelligent monitoring modules to ensure uniform seedling emergence and improve planting efficiency. It is suitable for farmland operations of different sizes.

[0003] Existing rapeseed planting and sowing equipment typically uses a fixed seeding structure, which makes it impossible to quickly and accurately adjust the seed output according to soil moisture, variety characteristics, or agronomic requirements. This results in cumbersome operation and difficulty in responding to different sowing needs in real time, affecting operational efficiency and sowing uniformity.

[0004] In summary, to improve the adaptability and accuracy of rapeseed sowing operations, it is necessary to address the problems of cumbersome seed output adjustment and slow response of existing sowing devices, so that the equipment can quickly adjust the sowing amount according to different soil conditions, variety characteristics and agronomic requirements, thereby improving sowing uniformity and operational efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable rapeseed planting and sowing device, including a hopper, the inside of which is provided with multiple equally spaced partitions, and multiple material drop boxes installed at the bottom of the hopper. Positioning seats are fixed on both the left and right sides of the hopper, and a rotating shaft is rotatably connected between two positioning seats. The rotating shaft passes through the multiple material drop boxes, and multiple adjusting rollers are fixed on the outside of the rotating shaft. Multiple sets of storage troughs of various specifications are opened on the outside of the adjusting rollers. A lead screw is rotatably connected to the left end of the rotating shaft, and the lead screw is threadedly connected to the hopper. A knob is fixed to the left end of the lead screw. A fixed frame is fixed on the inside of the hopper, and two sets of supports are installed on the fixed frame. Wheel frames are hinged to the two sets of supports. A drive shaft is rotatably connected to the inside of the wheel frames, and movable wheels are installed at both ends of the drive shaft. A furrowing mechanism is provided on the fixed frame, and a transmission mechanism is also provided on the fixed frame.

[0007] In a preferred embodiment, the trenching mechanism includes an installation component and an insertion component, wherein the installation component is used to fix the insertion component and the insertion component is used to insert into the soil.

[0008] In a preferred embodiment, the mounting assembly includes a plurality of fixing plates disposed on a fixing frame, with positioning rods connected to the fixing plates, and the fixing plates being fixedly connected to the fixing frame via the positioning rods.

[0009] In a preferred embodiment, the insertion assembly includes a fixing arm fixed to the inside of a fixing plate, and two inclined plates fixed to the outside of the fixing arm.

[0010] In a preferred embodiment, the transmission mechanism includes an adjustment component and a linkage component. The adjustment component is used to adjust the rotation angle of the wheel frame, and the linkage component is used to link the rotating shaft and the drive shaft.

[0011] In a preferred embodiment, the adjustment assembly includes a support arm fixed to the front side of the mounting bracket, a screw threaded onto the support arm, the bottom of the screw being rotatably connected to the wheel frame, and a rotating block fixed to the top of the screw.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 An adjustable rapeseed planting and sowing device includes a hopper 1. The hopper 1 has multiple equally spaced partitions 2 inside. Multiple material drop boxes 3 are installed at the bottom of the hopper 1. Positioning seats 4 are fixed on both the left and right sides of the hopper 1. A rotating shaft 5 is rotatably connected between two positioning seats 4. The rotating shaft 5 passes through the multiple material drop boxes 3. Multiple adjusting rollers 6 are fixed on the outside of the rotating shaft 5. Multiple sets of storage troughs 7 of various specifications are opened on the outside of the adjusting rollers 6. A lead screw 8 is rotatably connected to the left end of the rotating shaft 5. The lead screw 8 is threadedly connected to the hopper 1. A knob 9 is fixed to the left end of the lead screw 8. A fixing frame 11 is fixed inside the hopper 1. Two sets of supports 12 are installed on the fixing frame 11. Wheel frames 13 are hinged to the two sets of supports 12. A drive shaft 14 is rotatably connected to the inside of the wheel frames 13. Moving wheels 15 are installed at both ends of the drive shaft 14. A furrowing mechanism and a transmission mechanism are also provided on the fixing frame 11.

[0023] It should be noted that rotating the knob 9 drives the lead screw 8 to rotate, which in turn drives the rotating shaft 5 to move laterally. As the rotating shaft 5 moves, it can drive the adjusting roller 6 to move synchronously, thereby aligning the storage troughs 7 of different sizes with the seed discharge port to achieve stepless adjustment and realize rapid adjustment of the sowing density.

[0024] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 5 The trenching mechanism includes an installation component and an insertion component. The installation component is used to fix the insertion component, and the insertion component is used to insert into the soil.

[0025] It should be noted that the insertion component is fixed to the mounting component and is used for insertion into the soil.

[0026] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 5 The installation assembly includes multiple fixing plates 101 mounted on a fixing frame 11. A positioning rod 102 is connected to the fixing plate 101, and the fixing plate 101 is fixedly connected to the fixing frame 11 through the positioning rod 102.

[0027] It should be noted that the positioning rod 102 is U-shaped and can be adapted to the fixing frame 11. The fixing plate 101 is fixed to the fixing frame 11 by the positioning rod 102.

[0028] Refer to the instruction manual appendix Figure 5 The insertion assembly includes a fixing arm 103 fixed inside the fixing plate 101, and two inclined plates 104 fixed outside the fixing arm 103.

[0029] It should be noted that during sowing, the fixed arm 103 drives the inclined plate 104 to insert into the soil. As the device moves, a seed trench is opened, and the seeds fall directly into the bottom of the trench after being fed.

[0030] Refer to the instruction manual appendix Figure 1 and Figure 2 The transmission mechanism includes an adjustment component and a linkage component. The adjustment component is used to adjust the rotation angle of the wheel frame 13, and the linkage component is used to link the rotating shaft 5 and the transmission shaft 14.

[0031] It should be noted that the angle of the wheel frame 13 can be adjusted by adjusting the component. When the moving wheel 15 rolls, the rotating shaft 5 is driven to rotate through the cooperation of the drive shaft 14 and the linkage component.

[0032] Refer to the instruction manual appendix Figure 2 The adjustment assembly includes a support arm 161 fixed to the front side of the mounting bracket 11, a screw 162 threadedly connected to the support arm 161, the bottom of the screw 162 being rotatably connected to the wheel frame 13, and a rotating block 163 fixed to the top of the screw 162.

[0033] It should be noted that the rotating block 163 drives the screw 162 to rise and fall within the support arm 161, pushing the wheel frame 13 to rotate around the hinge point of the support 12, thereby changing the relative height of the moving wheel 15 with respect to the ground.

[0034] Refer to the instruction manual appendix Figure 2 The linkage mechanism includes a first sprocket 164 fixed on the outside of the rotating shaft 5, a second sprocket 165 fixed on the outside of the transmission shaft 14, a tension seat 167 provided on the fixed frame 11, and a chain 166 sleeved on the outside of the first sprocket 164, the second sprocket 165 and the tension seat 167.

[0035] It should be noted that when the movable wheel 15 rotates, it drives the second sprocket 165 through the drive shaft 14, which in turn drives the first sprocket 164 to rotate via the chain 166, ultimately causing the rotating shaft 5 to rotate synchronously. The tension seat 167 always keeps the chain 166 taut.

[0036] Working principle: Rotating the knob 9 drives the lead screw 8 to rotate. The lead screw 8 is threadedly connected to the hopper 1 and drives the rotating shaft 5 to move laterally. The rotating shaft 5 drives the adjusting roller 6 to move synchronously, so that the storage troughs 7 of different sizes are aligned with the seed discharge port of the dropping box 3, realizing stepless adjustment of the sowing density. During sowing, the fixed arm 103 is fixed to the fixed plate 101. The fixed plate 101 is connected to the fixed frame 11 through the U-shaped positioning rod 102. The fixed arm 103 drives the inclined plate 104 to insert into the soil to open the furrow. The seeds fall into the bottom of the furrow through the dropping box 3. When the moving wheel 15 rolls, it drives the second sprocket 165 to rotate through the transmission shaft 14. The first sprocket 164 is driven to rotate through the chain 166 and the tension seat 167, so that the rotating shaft 5 rotates to realize continuous sowing. At the same time, the rotating block 163 drives the screw 162 to rise and fall in the support arm 161, pushing the wheel frame 13 to rotate around the hinge point of the support 12, adjusting the height of the moving wheel 15 to adapt to different terrains.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
