Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1:

[0033] The harvesting device provided in this embodiment includes a square plate 1, a surrounding plate 4, a square frame 5, a digging shovel 6, a support unit, an electric telescopic rod 8, and an extension rod 9, wherein:

[0034] The square plate 1 can be an iron plate or a template. Protruding posts extend outwards from the four corners of the square plate 1, and a roller 2 is installed below each protruding post. The support and the surrounding plate 4 are both fixed to the square plate 1. The support is located outside the surrounding plate 4, and the space between the surrounding plate 4 and the square plate 1 forms a storage space for crops. The excavated crops are placed in this storage space. Optionally, several through holes are provided on the square plate 1 for passing through the soil. These through holes are located within the storage space. Soil from the roots of the crops placed in the storage space falls onto the square plate 1, and the soil from the square plate 1 falls out of the storage space through the through holes and is dislodged through the through holes by the movement of the entire device.

[0035] The frame 5 is hinged to the aforementioned support, and the excavator 6 is fixed to a straight rod 7. A first through hole is provided on the side wall of the frame 5, and the straight rod 7 is slidably inserted into the first through hole. A linear power assembly is also installed on the frame 5, and the power output end of the linear power assembly is connected to the straight rod 7, thereby driving the straight rod 7 to move the excavator 6 horizontally. An extension rod 9 is connected to the frame 5, and the extension rod 9 and the straight rod 7 are respectively located on both sides of the frame 5. Both the frame 5 and the excavator 6 mounted on it can rotate relative to the square plate 1, adjusting the angle at which the excavator 6 inserts into the soil during excavation. Specifically, in this embodiment, the support includes two upright plates 3 facing each other on the side of the above-mentioned enclosure 4. The bottom end of the upright plate 3 is fixed to the above-mentioned square plate 1. A circular hole is provided on the upright plate 3. The circular holes on the two upright plates 3 are coaxial. A circular shaft is provided on the two opposite outer walls of the above-mentioned square frame 5. The axial direction of the circular shaft is perpendicular to the extension direction of the above-mentioned electric telescopic rod 8. The two circular shafts are respectively rotatably inserted into the circular holes on the two upright plates 3, thereby realizing the hinge of the square frame 5 on the support.

[0036] When the harvesting device with the above structure is used to harvest crops, the device is first moved to the land where the crops are planted by means of the roller 2. Then, the digging shovel 6 is aligned with the soil under a crop. The linear power component drives the digging shovel 6 to extend into the soil. Then, the extension rod 9 is pressed, and by means of the lever principle, the digging shovel 6 digs upward, thereby digging out the roots of the crop from the soil. Then, the dug-out crop is picked up and stored in the above-mentioned holding space. Finally, the device is pushed forward to another crop that needs to be dug, and the above operation is repeated.

[0037] With the harvesting device provided in this embodiment, it is only necessary to move the device to a suitable position and press the extension rod 9 during the digging process. The device uses a linear power component to insert the digging shovel 6 into the soil, thereby helping to reduce some labor input. Compared with purely manual digging, this device is more labor-saving; compared with harvesting devices in the prior art, the device provided in this embodiment has a simpler structure, lower cost, and can achieve semi-automatic harvesting of crops.

[0038] Optionally, the aforementioned linear power assembly includes an electric telescopic rod 8. The push rod of the electric telescopic rod 8 is connected to the straight rod 7, thereby driving the straight rod 7 to move the excavator shovel 6 horizontally, thus helping the excavator shovel 6 to dig into or out of the soil. Of course, the aforementioned electric telescopic rod 8 is an electric device capable of high-frequency extension and retraction. During a single excavation, the electric telescopic rod 8 extends and retracts several times, digging a certain distance each time. An installation cylinder 10 is welded and fixed to the outer wall of the frame 5. The electric telescopic rod 8 is installed in the installation cylinder 10. A second through hole is also provided on the side wall of the frame 5. The first and second through holes are located on opposite sides of the frame 5. The push rod of the electric telescopic rod 8 is slidably inserted into the second through hole, and the straight rod 7 is connected to the push rod of the electric telescopic rod 8. An installation box 11 is also provided on the outer wall of the installation cylinder 10. A battery 12 is installed in the installation box 11, and a cover is installed at the opening of the installation box 11. The electric telescopic boom 8 is electrically connected to the battery 12 via a wire. A switch (not shown in the diagram) is mounted on the wire and installed on the extension rod 9, which is detachably and fixedly mounted on the mounting cylinder 10. When the extension rod 9 rotates, it drives the square frame 5 to rotate via the mounting cylinder 10. The square frame 5 then drives the straight rod 7 to rotate, which in turn drives the excavator shovel 6 to rotate. The extension rod 9 is made of wood. The electric telescopic boom 8 can be operated simply by manipulating the switch, making it easy to use.

[0039] Optionally, a screw head 13 is provided at one end of the extension rod 9. The screw head 13 includes a coaxially arranged iron cylinder and a tube. The extension rod 9 is interference-fitted into the tube. The outer wall of the iron cylinder is provided with external threads. The iron cylinder is screwed into the mounting cylinder 10, which is an iron cylinder. The electric telescopic rod 8 is pressed into the mounting cylinder 10 by the screw head 13. A rubber sheet 14 is adhered to the iron cylindrical end face of the screw head 13. The rubber sheet 14 is in contact with the electric telescopic rod 8. The rubber sheet 14 can prevent the electric telescopic rod 8 from directly contacting the hard screw head 13, thereby protecting the electric telescopic rod 8 from being crushed.

[0040] More preferably, a slide rail is provided on the inner wall of the aforementioned frame 5, with the length direction of the slide rail being in the same direction as the extension and retraction direction of the aforementioned electric telescopic rod 8. A slide rod 15 is slidably installed on this slide rail, located inside the aforementioned frame 5. The straight rod 7 and the push rod of the electric telescopic rod 8 are both connected to the slide rod 15. Specifically, the straight rod 7 and the push rod of the electric telescopic rod 8 are respectively connected to both sides of the slide rod 15. With the help of the slide rod 15, the translation of the straight rod 7 is made more stable.

[0041] More preferably, a protective cover 16 is also connected between the aforementioned frame 5 and the slide rod 15. The protective cover 16 is a structural component made of non-woven fabric and has good telescopic properties. The protective cover 16 covers the push rod of the electric telescopic rod 8, thereby reducing the chance of dust sticking to the push rod of the electric telescopic rod 8. During the translation of the slide rod 15, the protective cover 16 extends and retracts.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
