Description

Technical Field

[0001] The invention relates to the field of crop seedling planting, and in particular to a high-efficiency zero-speed well-digging, cellar-pit-planting integrated machine. Background Art

[0002] Well-pit transplanting refers to digging a well on the ridge during transplanting. The upper part of the well is cylindrical and the lower part is conical. The crop seedlings are then dropped vertically into the well. Since the cone angle of the substrate at the root of the crop seedlings is equal to the cone angle of the lower part of the well, the posture of the crop seedlings always remains vertically upward. Finally, the substrate at the root of the crop seedlings is completely covered with crushed soil with appropriate moisture content. This is a new planting technology.

[0003] At present, the well-cellar transplanting is carried out by hand, with a well-cellar making machine on one's back, a small gasoline engine as the power source, and a handheld hole-punching device for punching holes. Although this method of making well-cellars meets the requirements of agronomic planting, it has a low degree of automation, high labor intensity, and low work efficiency, and cannot be widely promoted and applied. In the prior art, some well-cellar water-injection seedling transplanting machines are disclosed. Since the machine needs to carry water to assist in the formation of the well-cellar, the machine is heavy, the travel speed is slow, and the transplanting efficiency is low; the amount of water injected into each well-cellar is affected by the machine's travel speed, the drill bit's penetration speed, etc., which has a certain impact on the quality of the well-cellar formation; and the well-cellar device of the existing well-cellar hole-punching transplanting machine is a parallel four-bar mechanism-gear-sprocket combination structure. This structure is significantly affected by the machine's travel speed during the well-cellar production process. The slow machine travel speed leads to a good well-cellar forming effect. Once the speed is fast, the well-cellar forming effect is poor, and a trumpet-shaped or unformed situation occurs. Summary of the invention

This structure is significantly affected by the machine's travel speed during the well-pit manufacturing process. When the machine travels at a slow speed, the well-pit molding effect is good.

[0032] Further, such as Figure 7 , Figure 8 , Fig. 9 As shown, the seedling tray assembly in this embodiment includes two sprockets 59, a chain plate 60 and a limit rod 64, one of the sprockets 59 is an active sprocket, and the other is a passive sprocket. The two sprockets are connected by the chain plate 60, and a plurality of seedling trays are arranged on the chain plate 60.

The left half shell and the right half shell are semi-conical, and a lower connecting piece 534 is arranged on the upper part. The lower connecting piece is connected to the upper connecting piece by bolts. The seedling throwing device 53 is designed in this form mainly to facilitate the adjustment of the area of ​​the seedling throwing device according to the size and shape of the seedlings.

[0035] Furthermore, two contour wheels 63 are arranged at the front end of the self-propelled chassis, and the contour wheels 63 mainly function to keep the integrated machine moving along the shape of the ridge.

[0036] The specific working principle is as follows: The end sprocket 5 of the transmission system rotates at the same speed as the first gear 6, and the irregular cam 10 rotates at the same speed as the second gear 7. Through the meshing movement of the first gear 6 and the second gear 7, the movement direction of the well-drilling device is opposite to the traveling direction of the machine during the movement of the machine. Under the action of the irregular cam 10, the traveling speed of the well-drilling device is equal to that of the machine. At this time, the hole-forming drill bit has a zero speed condition in the horizontal direction.

[0037] The crank 11 and the irregular cam 10 are arranged according to the set phase angle, and the hole-forming drill bit 50 realizes the function of digging a well by moving up and down in the vertical direction. In the process of the contact point between the well-digging device and the irregular cam 10 moving from the base point to the highest point, the hole-forming drill bit 50 completes the whole process from entering the soil to coming out of the soil, and the contact point suddenly changes from the highest point to the base circle. In the process of contacting on the base circle, the hole-forming drill bit moves from the highest position to the position in contact with the ground, and then completes a complete planting cycle, and then repeats the action. During the forward movement of the machine, the hole-forming drill bit 50 remains stationary in the horizontal direction relative to a certain point on the ground, and moves up and down in the vertical direction to realize digging a well. During the forward movement of the machine, the hole-forming drill bit continuously realizes efficient zero-speed well digging. Under the action of the spring 15, the rolling wheel 51 of the well-digging device and the irregular cam 10 are always in contact. When the machine is moving, the well-drilling device moves according to the shape of the irregular cam 10, so that the well-drilling device reciprocates back and forth regularly and the hole-forming drill moves up and down regularly.

[0038] Furthermore, under the conditions that the soil moisture content, soil particle size after ridge formation, and compactness meet the conditions for forming a well pit, the transplanter can be used for both well pits on and under the film. The specific working process is as follows: The gasoline engine drives the input pulley of the gearbox through the V-belt, and the output shaft of the gearbox is transmitted to the running wheels of the chassis through the chain transmission, so that the chassis obtains the power and speed to move forward; the other way is transmitted to the clutch sprocket, and then transmitted to the well-digging device through the second chain transmission mechanism 57 and to the seedling tray assembly through the first chain transmission mechanism 56; when the transplanter is not working, the clutch is opened, the well-digging device and the seedling tray assembly are not working, and the machine can travel. When the transplanter is working, the clutch is closed, and the well-digging device and the seedling tray assembly are in motion. A pair of gears plays a reversing role. When working, under the action of spring tension, the roller of the well-drilling device is always in contact with the irregular cam. The well-drilling device moves according to the shape of the irregular cam, and the speed is equal to and opposite to that of the walking chassis in the horizontal direction. The hole-forming drill bit is in a stationary state in the horizontal direction relative to the well-drilling point on the ground. At the same time, the hole-forming drill bit moves up and down in the vertical direction. The micro motor drives the hole-forming drill bit to rotate. Under the above conditions, the hole-forming drill bit completes the zero-speed well-drilling function. The machine moves continuously, and the hole-forming drill bit repeatedly drills wells. The seedling duckbill and the drill bit maintain a predetermined plant spacing. While drilling the well, the seedling duckbill is used to achieve intermittent seedling leakage, and the crop seedlings fall into the well.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
