Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery, in particular to a seedling supporting and soil covering machine. BACKGROUND

[0002] Many crops need to be covered with soil during production, for example, leeks are covered with soil to promote the growth of new roots, prevent lodging, and increase yield. Yellow leeks are simply called leeks. When leeks grow to a certain height, their stems and leaves will lodge on the ridge surface. The soil covering requirement is that the soil cannot cover the leek leaves and the soil should be in contact with the leek root pseudostem. Since soil covering needs to be done multiple times, the cross section of the ridge after soil covering is trapezoidal. Currently, there is a lack of mechanical soil covering technology for leeks, which requires three people to complete soil covering at the same time. One person uses two bamboo poles to approach and insert into both sides of the root of each row of leeks, then lifts one end of the bamboo pole upward to clamp and support the lodged leek stems and leaves on the ridge surface, exposing the leek root pseudostem and the ridge surface. The other two people use hoes to cover soil to the leek roots from both sides. This method has high labor intensity and increases the planting cost of farmers. Existing soil covering equipment for large onions and the like does not have a seedling supporting technology, and the soil covering and seedling supporting height cannot be adjusted. Using such equipment for leek soil covering will damage the leek stems and leaves, causing leek lodging, and the ridge shape after soil covering is conical, which does not meet the agronomic requirements of multiple soil covering for leeks.

[0003] Prior art one: Chinese invention patent with publication number CN103026817B, which provides a suitable inter-ridge operation cultivator. The cultivator provides a suitable inter-ridge operation cultivator for ditching, ridging, and soil covering operations that is convenient, efficient, and fast. The cultivator includes a frame composed of a frame 1 and a support fixed in front of the frame, and a power device, a soil covering device, a walking device, and a control device connected to the frame. The soil covering device includes left and right V-shaped mudguards symmetrically connected to the sides of the support, and two left and right soil covering knives respectively arranged on both sides of the support and fixedly connected to the knife shafts. The left and right soil covering knives each include a soil covering knife support and a plurality of blades evenly distributed along the circumference of the soil covering knife support. When rotating, the blades turn the soil and transport it upward and to the side. The left and right V-shaped mudguards limit the soil transported by the left and right soil covering knives, causing it to be transferred to the ridge, thereby achieving soil covering.

[0004] The working process of the cultivator is as follows: the cultivator is placed in the ridge ditch, the handle is held, the power machine is started, the power is transmitted from the driving wheel to the driven wheel, and then the driving wheel shaft of the gearbox is rotated; the driving wheel shaft drives the wheel shaft and the plow blade shaft to rotate through the transmission mechanism in the gearbox, and then drives the wheel and the left and right soil cultivating knives to rotate, so that the soil can be cultivated, ditched and ridged through the continuous operation of the wheel, the left and right soil cultivating knives. Adjusting the forward and backward handle can adjust the forward and backward movement of the cultivator; adjusting the wheel handle can adjust the speed of the wheel rotation; adjusting the soil cultivating knife handle can adjust the speed of the left and right soil cultivating knife rotation.

[0005] The advantages and disadvantages of the prior art are as follows:

[0006] The technical scheme can be conveniently, efficiently and quickly used for ditching, ridging and soil cultivating, but does not meet the leek soil cultivating agricultural requirements, mainly manifested in:

[0007] 1. Lack of seedling supporting device, leek stems and leaves are laid on the ridge surface during soil cultivating, which directly causes damage to leek stems and leaves and affects leek growth.

[0008] 2. Does not meet the leek multiple soil cultivating agricultural requirements, as the soil cultivating times increase, the soil cultivating and seedling supporting height also increase, and the ridge shape after soil cultivating is conical, which is not conducive to the next soil cultivating operation.

[0009] Prior art two: a new type of cross-row adjustable cultivator is provided in CN108184344B Chinese patent, which comprises a protective sleeve, a clutch handle, a control clutch line, a right side handrail, a left side handrail, a fixing screw, a connecting frame, a row distance adjusting device, an operation button, a mud guard, a movable soil cultivating wheel, a rear rotating shaft, a fixed soil cultivating wheel, a front rotating shaft, a supporting wheel, a supporting wheel fixing frame, a anti-collision frame, an engine, an engine oil tank and an engine oil filler, and the connecting frame bottom end is provided with a row distance adjusting device. When the soil cultivating row distance needs to be adjusted, the operation button on the side of the row distance adjusting device is controlled to start the adjusting motor, the adjusting motor drives the motor rotating shaft to rotate, the motor rotating shaft synchronously rotates with the lower belt pulley, the lower belt pulley drives the upper belt pulley to rotate through the transmission belt, the upper belt pulley is fixedly connected with the cam rotating shaft, the cam rotating shaft rotates, the cam rotating shaft drives the cylindrical cam to rotate, the cylindrical cam is engaged with the adjusting block, the adjusting block moves left and right, the right side limiting plate and the left side limiting plate on both sides of the cylindrical cam limit the adjusting block to prevent the adjusting block from disengaging from the cylindrical cam, the adjusting block drives the adjusting rod to move, the adjusting wheel cooperates with the adjusting groove to make the adjusting device more stable, the adjusting block bottom end is provided with a shock absorbing spring to reduce the vibration generated during soil cultivating, the adjusting rod is connected with the movable soil cultivating wheel to achieve the purpose of adjusting the movable soil cultivating wheel horizontally, so as to realize the soil cultivating row distance adjustment and meet the soil cultivating row distance requirements of different plants.

[0010] Advantages and disadvantages of the prior art two are as follows:

[0011] The technical scheme solves the problem that the cultivator in the prior art cannot adjust the cultivation row distance according to the types of planted crops and cannot meet the requirements of agricultural production, but the technical scheme is still not satisfied with the requirements of leek cultivation, mainly showing that:

[0012] 1. The leek stems and leaves are laid on the ridge surface during cultivation, and the leek stems and leaves are damaged directly during cultivation without the support of the supporting device, which affects the growth of the leek.

[0013] 2. The requirements of leek cultivation are not met, and with the increase of the number of cultivation, the cultivation and supporting height also increase, and the shape of the ridge after cultivation is conical, which is not conducive to the next cultivation operation.

[0014] In summary, the technical problems to be solved by the present application are as follows:

[0015] 1. The problem of supporting leek during leek cultivation, the existing technology lacks a supporting mechanism, the supporting mechanism supports the leek stems and leaves laid on the ridge surface, exposes the ridge surface and the leek root and stem parts, and avoids the soil from pressing the stems and leaves after cultivation, which causes damage to the leek stems and leaves;

[0016] 2. The problem of ridge shaping during leek cultivation, the existing technology causes the shape of the ridge to be conical after cultivation, which is not conducive to the next cultivation operation. However, in actual production, the leek growing process requires multiple cultivations, and the shape of the ridge is required to be trapezoidal during the first few cultivations to meet the requirements of multiple cultivations.

[0017] 3. The height of the existing technology cannot be adjusted, and the requirements of multiple cultivations cannot be met. SUMMARY

[0066] The present invention provides a description of the working process of a soil-raising machine that mimics manual seedling support:

[0067] The soil-raising machine has three steps in the soil-raising process: supporting the seedlings, raising the soil, and shaping the ridge surface.

[0068] like Figures 1-3 As shown, before the machine operates, the relative positions of the adjusting pipe 75 and the horizontal pipe 74 are adjusted by tightening and loosening the fastener 77 to control the width between the two seedling supports 73, according to the growth of crops such as chives and the number of times the soil is hilled. This is to meet the needs of different seedling widths. The position of the vertical pipe 76 relative to the adjusting pipe 75 is adjusted by the fastener 77 to control the vertical height of the seedling support 73, to meet the needs of different hilling heights. The adjustment of the rear seedling support frame 72 is the same as that of the front seedling support frame 71. The width of the front seedling support frame 71 is smaller than that of the rear seedling support frame 72 to avoid the front seedling support frame 71 blocking the seedlings. This allows the seedling support device 7 and the ridge shaping device 5 to meet the agronomical requirements of multiple hillings of chives.

[0069] The relative position of the adjusting plate 83 and the adjusting seat A85 is changed by adjusting the arc-shaped hole on the adjusting plate 83, thereby adjusting the angle of the upper baffle 81 relative to the frame 3 or the angle between the left and right upper baffles 81. In addition, the included angle between the lower baffle 82 and the upper baffle 81 is adjusted by tightening the locking bolt 84. When the soil flows towards the soil retaining device 8 during hilling, the direction and height of the soil flow are controlled by the upper baffle 81 and the lower baffle 82 to meet the agronomic requirements of multiple hilling operations.

[0070] During the hilling operation, the power unit 9 is started, and power is output from the power unit 9 and transmitted to the transmission unit 2, and then to the walking device 4 and the hilling device 6. The control device 1 is operated to make the entire machine move forward in the controlled direction. The axle of the third driven wheel 23 drives the blade holder 62 to rotate, and the hilling blade 61 begins the hilling operation. The soil in the furrows is broken up and thrown forward and upward. During the machine's forward movement, the lower end of the lower side bar of the seedling support frame 731 on the seedling support device 73 first lifts up the leek stems and leaves that have fallen on the ridge surface, and the upper side bar of the seedling support frame 731... Under the action of the seedling support board 732, the leek stems and leaves are lifted and straightened. The pseudostem of the leek root and the ridge surface will be exposed inside the seedling support board 732. The soil thrown up by the hilling knife 61 becomes more fragmented under the action of the upper baffle 81 and the lower baffle 82 and flows to the leek root, so that a layer of soil accumulates on the ridge surface. The ridge shaping device 5's ridge top shaping plate 52 and ridge side shaping plate 53 respectively tidy up the soil on the ridge top and ridge side, so that the longitudinal section of the ridge after hilling is trapezoidal, and the soil will not fall into the furrow, which is conducive to the agronomic requirements of multiple hilling of leeks.

[0071] The above examples are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above examples. Any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be pointed out that improvements and refinements made by those of ordinary skill in the art without departing from the principles of the present application should also be considered as falling within the protection scope of the present application.
