Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a taro digging, soil-patting, harvesting machine. Background Technology

[0002] my country has abundant taro resources, mainly distributed in the Pearl River, Yangtze River, and Huai River basins. Taro is an important vegetable and grain crop with high nutritional and medicinal value, making it a suitable food for all ages. Besides its primary use for starch production, taro can also be used for vinegar making, winemaking, protein separation, and alkaloid extraction. Current taro harvesting technology generally relies on manual digging and patting of the soil, resulting in low harvesting efficiency. Furthermore, digging taro out of the soil requires considerable effort. Therefore, there is an urgent need for a taro digging, patting, and harvesting machine. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a taro digging, soil-pulling, harvesting, and picking machine that is simple in structure, reasonable in design, and easy to use, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a mounting cylinder, a handle, and support legs. Several support legs are fixedly arranged with equal rounded corners on the four sides of the mounting cylinder, and handles are symmetrically fixedly arranged on the left and right side walls of the mounting cylinder.

[0005] It also includes:

[0006] A rotating cylinder, the upper end of which is rotatably inserted into the interior of the mounting cylinder via a bearing, and a digging mechanism is provided on the inner and outer sides of the rotating cylinder in cooperation.

[0007] Taro lifting mechanism, wherein the taro lifting mechanism is disposed on the upper side inside the mounting cylinder;

[0008] The soil-tapping mechanism is located inside the mounting cylinder and below the taro lifting mechanism.

[0009] Through the above technical solution design, when digging and harvesting taro, the device is transferred by a handle; before harvesting, the stems and leaves on the taro are cut off, leaving 20-30cm of stem on the upper side of the taro fruit; the device is operated by a single person, the harvesting worker lifts the device by the handle, and sets the device on each taro plant one by one by the support legs. First, the digging mechanism cuts a cone-shaped block out of the taro and the surrounding soil. Then, the digging mechanism is retracted, and the taro lifting mechanism clamps the reserved stem on the upper side of the taro fruit, lifting the taro and soil into the installation cylinder. The soil is then knocked off the taro by the soil-beating mechanism, and the taro harvesting is completed.

[0010] As a further improvement of the present invention, the excavation mechanism includes:

[0011] The fixed base is integrally formed on the inner wall of the rotating cylinder. One side wall of the fixed base is inclined. A first electric push rod is fixedly installed on the inner top surface of the fixed base. A knife holder is fixedly connected to the lower end of the first electric push rod. The first electric push rod is connected to an external power source.

[0012] The blade is fixedly mounted on the blade holder.

[0013] A toothed ring, wherein the toothed ring is fixedly mounted on the four sides of the rotating cylinder;

[0014] The No. 1 motor is fixedly mounted on the outer wall of the mounting cylinder by a motor bracket. A drive gear is fixedly connected to the output shaft of the No. 1 motor, and the drive gear meshes with a gear ring. The No. 1 motor is connected to an external power source.

[0015] With the above technical solution design, when the No. 1 electric push rod is opened, the No. 1 electric push rod extends so that the blade is inserted into the soil at an angle. When the No. 1 motor is opened, the output end of the No. 1 motor drives the drive gear to rotate, which in turn meshes and drives the gear ring to rotate, so that the rotating cylinder rotates around the center line of the mounting cylinder as the axis center line, and then the blade cuts the soil around the taro fruit. Since one side of the fixed seat is set at an angle, the protrusion cut by the blade is set in an inverted cone shape.

[0016] As a further improvement of the present invention, a guide groove is provided on the inclined surface of the fixed seat, and the tool holder is slidably embedded in the guide groove through the flange thereon.

[0017] Through the above technical solution design, the setting of the No. 1 guide groove limits and guides the up and down movement of the cutter holder, ensuring the accuracy of the blade's soil entry direction.

[0018] As a further improvement of the present invention, the taro lifting mechanism includes:

[0019] The mounting strips consist of two strips, which are symmetrically fixedly installed on the front and rear sides inside the mounting cylinder. Each mounting strip has a second guide groove. A guide block is slidably installed inside each second guide groove. The mounting strips on the front and rear sides are fixedly connected by a connecting strip.

[0020] Support bars, there are two support bars, which are symmetrically arranged on the left and right sides above the mounting bar, and the bottom surface of the support bars is fixedly set on the top surface of the guide block;

[0021] The second electric actuator consists of two actuators, which are vertically fixed on the bottom surface of the support bars on the left and right sides respectively; the second electric actuator is connected to an external power source.

[0022] Clamping plates, there are two clamping plates, and they are respectively fixedly installed at the lower ends of the two No. 2 electric push rods;

[0023] The telescopic frame is a multi-layer cross-folding frame. The left and right ends of the telescopic frame are respectively rotatably mounted on the side walls of the support bars on the left and right sides via hinge seats; the lower end of the rotating shaft in the middle of the telescopic frame is rotatably mounted on the top surface of the connecting bar via a bearing.

[0024] The No. 3 electric actuator is vertically fixed on the side wall of the support bar on the right side. The pushing end of the No. 3 electric actuator is connected to the end of the second hinge shaft from the right to the left of the telescopic frame through a rotating shaft and bearing. The No. 3 electric actuator is connected to an external power source.

[0025] Through the above technical solution design, the extension and retraction of the No. 3 electric push rod controls the extension and retraction of the telescopic frame, thereby controlling the spacing between the clamping plates connected to the lower side of the support bar; when lifting the taro, the No. 2 electric push rod extends, the clamping plates descend, and the height of the clamping plates is located on both sides of the taro stem. Then, by retracting the telescopic frame, the spacing between the clamping plates is reduced, and the clamping plates clamp the taro stem. Then, the No. 2 electric push rod is shortened, and the taro stem rises until the taro is located between the soil-patting mechanism.

[0026] As a further improvement of the present invention, several rubber blocks are fixedly arranged on the opposite surfaces of the clamping plates on both the left and right sides, and the rubber blocks are arranged in a semi-cylindrical shape.

[0027] Through the above technical solution design, when the clamping plate clamps the taro stem, the rubber block contacts the side of the taro stem to prevent the clamping plate from crushing the taro stem.

[0028] As a further improvement of the present invention, the soil-tamping mechanism includes:

[0029] The transmission gears are two in number and are rotatably mounted on the inner wall of the fixed cylinder via bearings, with the two transmission gears meshing with each other.

[0030] The second motor is fixedly mounted on the side wall of one of the shaft seats by a motor bracket, and the output shaft of the second motor is fixedly connected to the middle of one of the transmission gears; the second motor is connected to an external power source.

[0031] Two soil-beating rods are symmetrically fixed on two transmission gears and are located on the lower side of the clamping plate; the soil-beating rods are elastic rods.

[0032] Through the above technical design, the No. 2 motor is a forward and reverse motor. When the No. 2 motor is turned on, the output shaft of the No. 2 motor rotates intermittently in the forward and reverse directions. Through the transmission action of the transmission gear, the two soil-beating rods move in opposite directions, thereby continuously beating the soil clods on the outside of the taro in the middle of the clamping plate.

[0033] As a further improvement of the present invention, the lower end of each of the support legs is fixedly provided with a conical foot.

[0034] The above technical design, with its conical feet, makes it easier to insert the support legs into the soil, ensuring the stability of the device's operation.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. First, the taro fruit and soil clods are cut off from the bottom by the digging mechanism. Then, the taro lifting mechanism lifts the taro and soil clods out of the ground with the help of the taro stem. Finally, the soil clods are knocked away by the beating mechanism. The continuous operation eliminates the need for manual digging and soil removal, increases the overall mechanization of the device, and reduces the input of human resources.

[0037] 2. The entire device is transported via a handle, making it easy to operate, ensuring harvesting accuracy, and effectively preventing damage to other taro plants during picking. Attached Figure Description

The lower end of the first electric push rod 5-2 is fixedly connected to the knife holder 5-3 by bolts. The first electric push rod 5-2 is connected to an external power source, which is a portable power source.

[0058] The blade 5-4 is fixedly mounted on the blade holder 5-3 by bolts; a guide groove 6 is provided on the inclined surface of the fixed base 5-1, and the blade holder 5-3 is slidably embedded in the guide groove 6 through the flange on it; the guide groove 6 limits and guides the up and down movement of the blade holder 5-3, ensuring the accuracy of the blade 5-4's soil entry direction.

[0061] Through the above technical solution design, the first electric push rod 5-2 is opened, and the first electric push rod 5-2 extends so that the blade 5-4 is inserted into the soil at an angle. The first motor 5-6 is opened, and the output end of the first motor 5-6 drives the drive gear 5-7 to rotate, which in turn meshes and drives the gear ring 5-5 to rotate, so that the rotating cylinder 4 rotates around the center line of the mounting cylinder 1 as the axis center line, and then the blade 5-4 cuts the soil around the taro fruit. Since one side of the fixed seat 5-1 is set at an angle, the protrusion cut by the blade 5-4 is set in an inverted cone shape.

[0062] Example 3:

[0063] See as Figure 1-6 As shown, based on Embodiment 1, the taro lifting mechanism 7 includes:

[0064] Mounting strip 7-1, there are two mounting strips 7-1, which are symmetrically fixed to the front and rear sides inside the mounting cylinder 1 by bolts. Each mounting strip 7-1 has a second guide groove 7-2. A guide block 7-3 is slidably arranged inside the second guide groove 7-2. The mounting strips 7-1 on the front and rear sides are fixedly connected by connecting strip 7-9 and bolts.

[0066] Two electric actuators 7-5 are provided, and are respectively fixed vertically on the bottom surface of the support bars 7-4 on the left and right sides by bolts; the electric actuators 7-5 are connected to an external power source.

[0067] Clamping plates 7-6, there are two clamping plates 7-6, which are respectively fixed to the lower ends of two No. 2 electric push rods 7-5 by bolts. Several rubber blocks 8 are fixed to the opposite surfaces of the clamping plates 7-6 on the left and right sides by adhesive. The rubber blocks 8 are semi-cylindrical. When clamping the taro stem, the clamping plates 7-6 contact the side of the taro stem through the rubber blocks 8 to prevent the clamping plates 7-6 from crushing the taro stem.

[0068] Telescopic frame 7-7 is a multi-layer cross-folding frame. The left and right ends of the telescopic frame 7-7 are respectively rotatably mounted on the side walls of the support bars 7-4 on the left and right sides through hinge seats. The lower end of the rotating shaft in the middle of the telescopic frame 7-7 is rotatably mounted on the top surface of the connecting bar 7-9 through a bearing.

[0069] The third electric push rod 7-8 is vertically fixed to the side wall of the support bar 7-4 on the right side by bolts. The pushing end of the third electric push rod 7-8 is connected to the end of the second hinge shaft from the right to the left of the telescopic frame 7-7 through a rotating shaft and bearing. The third electric push rod 7-8 is connected to an external power source.

[0070] Through the above technical solution design, the extension and retraction of the No. 3 electric push rod 7-8 controls the extension and retraction of the telescopic frame 7-7, thereby controlling the spacing between the clamping plates 7-6 connected to the lower side of the support bar 7-4; when lifting the taro, the No. 2 electric push rod 7-5 extends, the clamping plates 7-6 descend, and the height of the clamping plates 7-6 is located on both sides of the taro stem. Then, by retracting the telescopic frame 7-7, the spacing between the clamping plates 7-6 is reduced, and the clamping plates 7-6 clamp the taro stem. Then, the No. 2 electric push rod 7-5 is shortened, and the taro stem rises until the taro is located between the soil-patting mechanism 9.

[0071] Example 4:

[0072] See as Figure 1 , 3 As shown in Figures 1 and 4, based on Embodiment 3, the soil-tamping mechanism 9 includes:

[0073] The transmission gear 9-1 consists of two gears, which are rotatably mounted on the inner wall of the fixed cylinder via a bearing seat, and the two transmission gears 9-1 are meshed together.

[0074] Motor 9-2 is fixedly mounted on the side wall of one of the bearings by a motor bracket and bolts, and the output shaft of motor 9-2 is fixedly connected to the middle of one of the transmission gears 9-1; motor 9-2 is connected to an external power source.

[0075] Two soil-beating rods 9-3 are symmetrically fixed and welded onto two transmission gears 9-1. The soil-beating rods 9-3 are located on the lower side of the clamping plate 7-6. The soil-beating rods 9-3 are elastic rods.

[0076] Through the above technical design, the No. 2 motor 9-2 is a forward and reverse motor. When the No. 2 motor 9-2 is turned on, the output shaft of the No. 2 motor 9-2 rotates intermittently in the forward and reverse directions. Through the transmission action of the transmission gear 9-1, the two soil-beating rods 9-3 move in opposite directions, thereby continuously beating the soil clods on the outside of the taro in the middle of the clamping plate 7-6.

[0077] The specific models of motor 1 (5-6), motor 2 (9-2), electric actuator 1 (5-2), electric actuator 2 (7-5), and electric actuator 3 (7-8) were purchased, installed, and used directly from the market according to the usage requirements.

[0078] When using this invention, the device is transferred by the handle 2 when digging and harvesting taro. Before harvesting, the stems and leaves on the taro are cut off, leaving 20-30cm of stem on the upper side of the taro fruit. The device is operated by a single person. The harvesting worker lifts the device by the handle 2 and sets the device on each taro plant by the support legs 3.

[0079] Open the first electric push rod 5-2. The first electric push rod 5-2 extends so that the blade 5-4 is inserted into the soil at an angle. Open the first motor 5-6. The output end of the first motor 5-6 drives the drive gear 5-7 to rotate, which in turn drives the gear ring 5-5 to rotate, so that the rotating cylinder 4 rotates in the middle of the mounting cylinder 1. Then the blade 5-4 cuts the soil around the taro fruit. Since one side of the fixed seat 5-1 is set at an angle, the protrusion cut by the blade 5-4 is set in an inverted cone shape. Then the digging mechanism 5 is retracted.

[0080] When lifting the taro, the second electric push rod 7-5 extends, and the clamping plate 7-6 descends. The height of the clamping plate 7-6 is located on both sides of the taro stem. Then, the telescopic frame 7-7 retracts, reducing the distance between the clamping plates 7-6, and the clamping plates 7-6 clamp the taro stem. Then, the second electric push rod 7-5 is shortened, and the taro stem rises until the taro is located between the soil-beating mechanism 9, lifting the taro and the soil into the installation cylinder 1. The second motor 9-2 is turned on, and the output shaft of the second motor 9-2 rotates intermittently in both directions. Through the transmission action of the transmission gear 9-1, the two soil-beating rods 9-3 move in opposite directions, continuously beating the soil clods on the outside of the taro in the middle of the clamping plate 7-6. The taro harvesting is then completed.

[0081] The beneficial effects of this specific embodiment after adopting the above structure are as follows:

[0082] 1. First, the digging mechanism 5 cuts all the taro fruits and soil clods off the bottom surface. Then, the taro lifting mechanism 7 lifts the taro and soil clods out of the ground with the help of the taro stem. Finally, the patting mechanism beats and removes the soil clods. This continuous operation eliminates the need for manual digging and soil removal, increases the overall mechanization of the device, and reduces the input of human resources.

[0083] 2. The entire device is transported via handle 2, which is convenient to operate, ensures the accuracy of harvesting, and effectively prevents other taro plants from being damaged during harvesting;

[0084] 3. The cone-shaped foot 10 makes it easier to insert the support leg 3 into the soil, ensuring the stability of the device operation.

[0085] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
