Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of puller, especially relates to a multifunctional sweet potato ridger. BACKGROUND

[0002] Because sweet potato has unique growth habit and planting method, before planting sweet potato, firstly, loosen the soil with rotary tillage machine, and then use the ridger to ridge and compact the loosened soil. The current sweet potato ridger comprises a frame body and at least one ridge pulling mechanism on the frame body, the ridge pulling mechanism comprises an upper ridge pulling plate, a side ridge pulling plate and a compression forming plate behind the side ridge pulling plate, which form a ridge pulling cavity. The sweet potato ridger is installed behind the rotary tillage machine, the loosened soil enters from the front of the ridge pulling cavity, and is ridged by the upper ridge pulling plate, the side ridge pulling plate and the compression forming plate. The existing multifunctional sweet potato ridger has the following defects: firstly, the side ridge pulling plate is single-layered, when the soil clod hit by the rotary tillage machine hits the side ridge pulling plate, the side ridge pulling plate vibrates violently, drives the whole frame body to vibrate, and makes the compression forming plate vibrate, which causes the soil on the side of the ridge back to fall off, and the ridging quality is poor; secondly, the inner side of the side ridge pulling plate is deformed due to the impact of the soil clod, the loosened soil hits the inner side of the side ridge pulling plate, and the rebound effect is poor, and the loosened soil is easy to stick to the inner side of the side ridge pulling plate, especially in the case that the soil humidity is relatively large, the ridging effect is poor; thirdly, the hard soil clod hitting the inner side of the side ridge pulling plate will be on the ridge surface, and is not easy to break, so that the smoothness of the side of the ridge back is poor, and the ridging effect is poor. SUMMARY

[0003] The utility model wants to solve the technical problem of providing a multifunctional sweet potato ridger with small frame body vibration, the inner side of the side ridge pulling plate is not easy to deform, the loosened soil is not easy to stick to the inner side of the side ridge pulling plate, less soil clod in the soil, and good ridging effect.

[0004] To solve the above problems, the technical scheme of the utility model multifunctional sweet potato ridger is as follows: comprising a frame body and at least one ridge pulling mechanism on the frame body, the ridge pulling mechanism comprises an upper ridge pulling plate, a side ridge pulling plate and a compression forming plate behind the side ridge pulling plate, which form a ridge pulling cavity, an outer ridge pulling plate is arranged on the horizontal direction outer side of the side ridge pulling plate, and a closed side cavity is formed between the outer ridge pulling plate and the side ridge pulling plate.

[0005] The additional technical features are as follows:

[0006] The side cavity is a triangular prism with the bottom edge in the front and the top corner in the rear;

[0007] A horizontal reinforcing plate is arranged on the outer side of the outer ridge pulling plate.

[0008] Compared with the prior art, the multifunctional sweet potato ridging machine provided by this utility model has the following advantages: Firstly, it includes a frame and at least one ridging mechanism located on the frame. The ridging mechanism includes an upper ridging plate, a side ridging plate, and a pressing and forming plate located behind the side ridging plate, which form a ridging cavity. An outer ridging plate is provided on the horizontal outer side of the side ridging plate, forming a closed side cavity between the outer ridging plate and the side ridging plate. When the soil swirled by the rotary tiller in front impacts the inner surface of the side ridging plate, the side ridging plate deforms under the impact force. Under the action of its own elasticity, the mixing action of the outer ridging plate and the gas in the closed side cavity, the side ridging plate quickly returns to its original shape. In this way, the impact force on the frame is reduced, the frame vibration amplitude is small, and the vibration amplitude of the pressing and forming plate is small during the forward movement, which will not cause soil to fall off the side of the ridge, resulting in good ridging quality. It further improves the strength of the entire side ridging plate and will not cause deformation of the inner side of the side ridging plate due to impact. First, the soil clods impacting the inner side of the side ridging plate are bounced off by the plate's elasticity. These bounced clods collide with incoming clods, offsetting the impact force of the incoming clods on the side ridging plate. Furthermore, the high relative velocity of the colliding clods makes them easily broken, resulting in fewer clods in the loose soil and a better ridging effect. Second, because the side cavity is a triangular prism with its base at the front and its apex at the rear, the side ridging plate closer to the front has greater elasticity than the one closer to the rear. Soil ejected from the front side ridging plate moves diagonally backward, colliding with soil flying towards the rear side ridging plate, reducing the impact force on the rear side ridging plate. This results in a smaller vibration amplitude on the rear side ridging plate, thus minimizing vibration during the pressing and forming process and improving the ridging effect. Third, the horizontal reinforcing plate on the outer side of the outer ridging plate prevents deformation of the ridging mechanism caused by soil impacts, increasing the strength of the ridging mechanism.

[0014] The outer pull ridge board 7, the side pull ridge board 5 and the closed side cavity 8 are relative to a big drum with drum cavity, and when the soil that the rotary cultivator rotates in front hits the inner surface of the side pull ridge board 5, the side pull ridge board 5 deforms under the impact force, and under the action of self-elastic force, the outer pull ridge board 7 and the gas mixing in the closed side cavity 8, the side pull ridge board 5 restores quickly, so that the impact force caused to the frame is reduced, the vibration amplitude of the frame 1 is small, the vibration amplitude of the extrusion forming plate 6 is small in the advancing process, and the soil on the ridge back side is not caused to fall off, the ridging quality is good, the strength of the whole side pull ridge board 5 is further improved, and the inner surface of the side pull ridge board is not caused to deform due to impact, the soil block hitting the inner surface of the side pull ridge board 5 is bounced off due to the elasticity of the side pull ridge board 5, the bounced-off soil block and the soil block coming from the front hit each other, the impact force of the soil block on the side pull ridge board 5 is offset, and the relative speed of the soil blocks hitting each other is large, so that the soil blocks are easily broken, the number of soil blocks in the loose soil is small, and the ridging effect is better.

[0015] The side cavity 8 is a triangular prism with the bottom edge in front and the top angle in back, so that the elasticity of the side pull ridge board 5 close to the front is large, and the elasticity of the side pull ridge board 5 close to the back is small, the soil bounced off on the front side pull ridge board moves to the obliquely back, hits the soil flying on the back side pull ridge board 5, the impact force on the back side pull ridge board 5 is reduced, the vibration amplitude of the side pull ridge board 5 close to the back is small, so that the vibration amplitude of the extrusion forming plate in the advancing process is small, and the ridging effect is good.
