Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a potato harvester. Background Technology

[0002] To address the prominent issue of "no suitable organic harvesters and difficulty in using organic harvesters" in harvesting potato crops, especially sweet potatoes, in hilly and mountainous areas, harvesters employing a soil-digging harvesting method have been developed in recent years. This machine first uses a soil-digging device to move the soil from both sides of the ridge to the corresponding furrow. Then, a digging shovel excavates and pushes the potato-soil mixture in the middle of the ridge. Finally, a material-separating mechanism and a conveyor chain peel and separate the potato-soil mixture. This significantly reduces the workload and resistance associated with digging, pushing, and separating. Furthermore, the soil in the middle of the ridge becomes looser after the soil-digging operation, facilitating digging, pushing, and separating, thereby greatly reducing power consumption, improving the potato-soil separation effect, and reducing the rate of potato burying. The structure of this machine is referenced in Chinese Invention Patent Application No. 202210502605.5, entitled "A Soil-Digging Device and Method for a Potato Harvester." In actual operation, there are often a certain amount of long stems on the ridges and at the bottom of the furrows, which can cause the machine's digging wheels to get tangled in the stems, reducing the digging effect and thus affecting the overall working effect of the machine. It is necessary to stop the machine regularly to clean the digging wheels, which also greatly reduces the operating efficiency of the equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a potato harvester with a soil-raking mechanism to prevent vines from getting entangled in the soil.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a potato harvester, including a frame and a soil-removing wheel set on the frame, the soil-removing wheel is provided with two or more sets of soil-removing blades arranged at intervals in the vertical direction, and also includes a cutter connected to the frame, the two or more cutters and the two or more sets of soil-removing blades are arranged alternately at intervals in the vertical direction.

[0005] Furthermore, the frame is equipped with a flow guide, which is located on the horizontal side of the excavator wheel, and the cutter is installed on the side of the flow guide facing the excavator wheel.

[0006] Furthermore, the cutter includes a cutting blade, the flow guide is provided with a base plate, and two or more cutting blades are arranged at intervals along the vertical direction on the base plate.

[0007] Furthermore, the cutter is an isosceles trapezoid in shape, with the cutting edge located at the waist.

[0008] Furthermore, the cutting edge is serrated.

[0009] Furthermore, the cutter is positioned diagonally behind the excavator wheel, facing away from the direction of travel of the frame.

[0010] Furthermore, the cutting tool is welded to the base plate.

[0011] Furthermore, the fairing is provided with mounting holes for locking the mounting plate.

[0012] Furthermore, each set of excavating blades includes two or more excavating rods spaced apart along the circumference.

[0013] Furthermore, the excavator wheel includes a rotating shaft, and the rotating shaft is provided with two or more L-shaped scraper blades along the circumferential direction. Two or more excavator rods are installed in correspondence with the two or more L-shaped scraper blades.

[0014] The beneficial effects of this utility model are as follows: A potato harvester uses a digging wheel with digging blades to rotate and dig the soil on both sides of the ridge to the corresponding furrow. This method offers good digging effect, low impact force, and low power consumption. A cutter is inserted into the digging wheel and works in a staggered pattern with the digging blades to efficiently cut long stems entangled in the digging wheel into short stems, which are then carried to the furrow with the soil flow, ensuring the normal operation of the digging wheel. During operation, as the digging wheel rotates, it digs the soil on both sides of the ridge to the corresponding furrow, completing the digging operation. The entire machine can excavate, push, and separate the potato-soil mixture in the middle of the ridge. If long stems are entangled in the digging wheel, the cutter will cut them into short stems, which are then carried to the furrow with the soil flow, preventing the stems from entangled in the digging wheel and affecting the efficiency and effect of the digging device. This significantly reduces power consumption, improves potato-soil separation, and reduces the rate of potato burying, helping to solve the prominent problem of "no usable machine and difficult-to-use organic machine" in the harvesting of potato crops, especially sweet potatoes, in hilly and mountainous areas.

[0022] Please refer to Figures 1 to 4 As shown, a potato harvester of this utility model includes a frame 1 and a soil-removing wheel 2 mounted on the frame 1. The soil-removing wheel 2 is provided with two or more sets of soil-removing blades 21 arranged at intervals in the vertical direction. It also includes a cutter 3, which is connected to the frame 1. Two or more cutters 3 and two or more sets of soil-removing blades 21 are arranged alternately at intervals in the vertical direction.

[0023] As can be seen from the above description, the beneficial effects of this utility model are as follows: a potato harvester, in which the digging wheel 2 rotates and digs the soil on both sides of the ridge 5 to the corresponding furrow 6 through the digging blade 21, has a good digging effect, low impact force and low power consumption. The cutter 3 is inserted into the digging wheel 2 and interlaced with the digging blade 21, which can efficiently cut the long stems and vines wrapped by the digging wheel 2 into short stems and vines and dig them to the furrow 6 with the soil flow, ensuring the normal operation of the digging wheel 2. During operation, as the soil-digging wheel 2 rotates, it digs the soil on both sides of the ridge 5 to the corresponding furrow 6, completing the soil-digging operation.

With this design, when one side is worn, the two cutters 3 can be swapped left and right for reuse, thus improving their service life.

[0029] In an optional embodiment, the cutting edge 311 is serrated.

[0030] As can be seen from the above description, the cutting edge 311 is serrated, resulting in a good cutting effect.

[0031] In an optional embodiment, the cutter 31 is located diagonally behind the excavator wheel 2 in the direction of travel of the frame 1.

[0032] As can be seen from the above description, the cutter 3 is located on the outer rear side of the soil-removing wheel 2, so that the cutting blade can cut the stems at an angle close to 90°, which is beneficial to improving the cutting effect of the stems.

[0033] In an alternative embodiment, the cutter 31 is welded to the base plate 32.

[0034] In an optional embodiment, the flow guide 4 is provided with mounting holes for locking the mounting plate 32.

[0035] In an optional embodiment, each set of excavating blades 21 includes two or more excavating rods 211 spaced apart along the circumferential direction.

[0036] In an optional embodiment, the soil-dredging wheel 2 includes a rotating shaft 22, and the rotating shaft 22 is provided with two or more L-shaped scraper plates 23 along the circumferential direction. Two or more soil-dredging rods 211 are installed in a one-to-one correspondence with the two or more L-shaped scraper plates 23.

[0037] As can be seen from the above description, a cutter 3 is set at the lower end of the L-shaped scraper 23 and between each pair of two or more sets of scraper blades 21.

[0038] Please refer to Figures 1 to 4 As shown, the first embodiment of this utility model is: a potato harvester, including a frame 1 and a soil-removing wheel 2 mounted on the frame 1. A vertical soil-removing wheel 2 is symmetrically arranged on each of the left and right sides of the frame 1. The soil-removing wheel 2 is provided with two or more sets of soil-removing blades 21 arranged at intervals in the vertical direction. It also includes a cutter 3, which is connected to the frame 1. Two or more cutters 3 and two or more sets of soil-removing blades 21 are arranged alternately at intervals in the vertical direction.

[0039] The frame 1 is equipped with a guide shroud 4, which is located on the horizontal side of the excavator wheel 2. The cutter 3 is installed on the side of the guide shroud 4 facing the excavator wheel 2. The cutter 3 includes a cutter blade 31. The guide shroud 4 is equipped with a base plate 32. Two or more cutters 31 are arranged vertically at intervals on the base plate 32. The cutter blade 31 is in the shape of an isosceles trapezoid, and the cutter blade 311 is located at the waist edge. The cutter blade 311 is serrated. The cutter blade 31 is located diagonally behind the excavator wheel 2 in the direction of travel away from the frame 1. The cutter blade 31 is welded to the base plate 32. The guide shroud 4 is provided with mounting holes for locking the base plate 32. Each set of excavator blades 21 includes two or more excavator rods 211 arranged at intervals in the circumferential direction.

The frame 1 is equipped with a transmission box 11, which includes a power input end and a power output end. The power output end is splined to the digging wheel 2. Power is input from the power input end, transmitted through the transmission, and output from the power output end to drive the digging wheel 2 to rotate. The two digging wheels 2 rotate in opposite directions, from the inside out and rear. This design facilitates the two digging wheels 2 to directly dig the soil from both sides of the ridge 5 to the inside of the corresponding furrow 6, while reducing the power consumption for digging.

[0040] In summary, this utility model of a potato harvester utilizes a digging wheel with rotating blades to dig the soil on both sides of the ridge to the corresponding furrow. This method offers excellent digging efficiency, low impact, and low power consumption. A cutter inserted into the digging wheel, working in a staggered pattern with the blades, efficiently cuts long vines entangled in the wheel into shorter pieces, which are then carried to the furrow with the soil flow, ensuring the digging wheel operates normally. During operation, as the digging wheel rotates, it digs the soil on both sides of the ridge to the corresponding furrow, completing the digging operation. The entire machine can excavate, push, and separate the potato-soil mixture in the middle of the ridge. If long vines are entangled in the digging wheel, the cutter will cut them into shorter pieces, which are then carried to the furrow with the soil flow, preventing the vines from affecting the efficiency and effectiveness of the digging device. This significantly reduces power consumption, improves potato-soil separation, and reduces the rate of potato burying, helping to solve the prominent problem of "no usable machine, difficult to use organic" in harvesting potato crops, especially sweet potatoes, in hilly and mountainous areas.
