DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] As shown in the accompanying drawings, the novel high-speed sweet potato harvesting plow proposed by the present invention has the following specific structure:

[0022] It comprises a frame 1, the frame 1 is arranged in a triangular structure, an inclined support beam 2 is arranged on the top of the frame 1, and a pulling point 20 is arranged on the top of the inclined support beam 2 for connecting with an external pulling device; a lower hinge point 3 is arranged on both sides of the front end of the frame 1, and the lower hinge point is used to connect with the lifting device of the external driving device; a side support rod 16 is arranged on both sides of the lower hinge point 3, and a vertical limit adjustment wheel 4 is fixed on the side support rod 16 through a horizontal sliding sleeve 17; A seedling-killing plate 5 is fixed at the rear end of the frame 1, and a driving device is fixed on the seedling-killing plate 5 to drive the shearing knife 5 to swing in front of the seedling-killing plate 5 to achieve a shearing action and thus destroy the seedlings; a vertical plate 6 is arranged below the seedling-killing plate 5, and a trenching knife group is arranged at the front end and left and right sides of the vertical plate 6. The trenching knife group is a multi-piece combination type, and the trenching knife group can achieve trenching and soil division width adjustment through a multi-piece structure; below the trenching knife group is a plow blade 12, and the plow blade 12 is a combined welded structure design, and the multi-piece combined welding strength is high.

[0023] Furthermore, the design focus of the present invention is that the trenching cutter group can adjust the trenching and soil division width, such as Figure 4 and Figure 5As shown, the trenching knife group described in the present device is divided into a front trenching knife 8 and a side trenching knife 9. The cross-section of the front trenching knife 8 gradually increases from top to bottom, and a side trenching knife 9 is fixed on the left and right sides of the front trenching knife 8 respectively through a rotating shaft structure; the rear sides of the side trenching knives 9 are each provided with a rotating shaft seat, and a horizontal guide rod 7 is provided on the rear side of the vertical plate 6 toward the rear side, and a sliding sleeve 71 is provided on the horizontal guide rod 7, and hinge seats 73 are provided on the left and right sides of the sliding sleeve 71. The hinge seats 73 on the left and right sides correspond to the rotating shaft seats on the left and right side trenching knives respectively and a support rod 72 is connected between the two. When in use, the fixed angle of the side trenching knife 9 on the front trenching knife 8 is adjusted by adjusting the sliding sleeve 71 forward and backward, so as to adapt to the harvest of different crops such as potatoes, taro, radish and other root fruits. The top of the side trenching knife 9 is provided with a top inclined surface 91, which realizes the side separation of the trenching soil by rolling the soil outward, while ensuring that the soil will not enter the combination area of ​​the horizontal guide rod 7 and the sliding sleeve 71, and will not affect the adjustment function of the horizontal guide rod 7 and the sliding sleeve 71.

[0024] On the basis of the above structure, further, a tail rod 13 is fixed to the rear side of the vertical plate 6 below the horizontal guide rod 7, and a wear-resistant block 14 is bolted to the bottom of the rear end of the tail rod 13. The purpose of setting the tail rod 13 is to prevent the entire equipment from deviating to the left or right during operation. At the same time, the setting of the wear-resistant block can prevent the end of the tail rod from being damaged after long-term friction.

[0025] The device is equipped with a seedling-killing function based on the existing structure. The seedling-killing action is achieved by driving a hydraulic motor. Figure 2 and Figure 5 As shown, a driving plate 52 connected to a hydraulic motor 51 is provided on the rice seedling killing plate 5, the driving plate 52 and the upper end of the transition plate 53 are hinged and fixed, and a safety block 54 is hinged at the lower end of the transition plate 53, and the safety block 54 is fixed to the shearing knife 55 by connecting bolts, and the middle part of the shearing knife 55 is hinged and fixed to the vertical plate 6. The shearing knife 55 can swing up and down under the drive of the safety block 54, and the shearing knife 55 is tangent to the vertical plate 6 when swinging up and down to realize shearing force. When the safety block 54 and the shearing knife 55 are combined, the bolts between the two are small. When the shearing knife 55 encounters greater resistance when swinging up and down, in order to prevent damage to the entire rice seedling killing functional component, protection is achieved by destroying the bolts between the two.

[0026] In summary, the present invention adopts the above structural setting, which adopts a triangular structure to set the entire frame 1, and connects the seedling-killing plate 5 and the vertical plate 6 on the rear side of the frame 1. A furrowing knife group is fixed on the front side of the vertical plate 6. The furrowing knife group is composed of multiple pieces, and can realize the artificial adjustment of the expansion angle, so as to adapt to the harvesting of different crops. Furthermore, the device is provided with a hydraulic motor 51 on the seedling-killing plate 5, and the hydraulic motor 51 drives the tool to swing up and down to realize shear force, so as to cut the seedlings; furthermore, the plow blade 12 of the device adopts a splicing structure setting, which has high bonding strength and stable performance.

[0027] The device has a novel structure and is easy to use. It can greatly improve the harvesting efficiency of root crops such as sweet potatoes and potatoes. In addition, the device integrates seedling killing and fruit harvesting, and is an ideal new high-speed sweet potato harvesting plow.
