Description

Technical Field

[0001] The invention belongs to the technical field of asparagus harvesting, and in particular relates to a modular asparagus harvesting device which is easy to assemble and disassemble. Background Art

[0002] Asparagus cochinchinensis (Tiandong) is a tuberous root of the Asparagus cochinchinensis plant. It is long, spindle-shaped, slightly curved, and has an opaque core. It ranges from 5 to 18 cm in length, with small segments measuring 0.5 to 2 cm in diameter. Its surface is yellowish-white or light yellowish-brown, translucent, smooth, or with varying degrees of longitudinal wrinkling, occasionally with remnants of gray-brown skin. It nourishes yin, clears heat, moistens the lungs, and nourishes the kidneys. It is used to treat yin deficiency fever, lung abscesses, and diabetes. Generally, the younger the root, the lower the rate of tender roots breaking off and the lower the yield. Therefore, it is usually cultivated for at least four years before harvesting, resulting in a higher market price for Asparagus cochinchinensis.

[0003] Traditional harvesters typically use a digging shovel to dig out the asparagus, then use the digging shovel's vibration to separate the roots from the soil. The asparagus is then transported through a conveyor mechanism, where a chain mesh further separates the roots from the soil. The asparagus, now separated from the soil, is then discharged into the field. Traditional harvesters and digging shovels are fixed together and cannot be disassembled. Therefore, if the harvester malfunctions, the asparagus can be harvested only incompletely or harvesting efficiency can be significantly reduced, which can delay the harvest and cause unnecessary trouble for the user.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] The object of the present invention is to provide a modular asparagus harvesting device that is easy to disassemble and assemble, which can solve the problem in the prior art that asparagus harvesting devices are difficult to disassemble and assemble.

[0006] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0007] The modular asparagus harvesting device is easy to disassemble and assemble, and includes: a harvesting shovel trunk, a shovel assembly, a sliding support mechanism, and a fixing mechanism;

[0008] The shovel assembly is mounted on the harvest shovel trunk, and includes an interval support block, which is fixedly connected to the harvest shovel trunk. A fixed shovel is mounted on the interval support block, and a plurality of linkage holes are drilled on the fixed shovel. Auxiliary shovels are provided on both sides of the fixed shovel, and a sliding support frame is slidably connected to the auxiliary shovel.

[0009] The sliding support mechanism is installed on one side of the harvesting shovel trunk, and the sliding support mechanism includes a sliding guide rail, an adjustment groove and a plurality of fixing holes are bored on the sliding guide rail, a sliding support frame is provided in the adjustment groove, a fixed shaft is installed in the sliding support frame, a fixed socket is bored on the fixed shaft, and a pad assembly is rotatably connected to the fixed shaft;

[0010] The fixing mechanism is installed on the sliding guide rail, and is used to fix the position of the sliding support frame, thereby preventing the pad block assembly from sliding any further.

[0011] In one or more embodiments of the present invention, a pair of sliding cavities are excavated on the main trunk of the harvesting shovel, which are used for the sliding and guiding of the sliding support guide block, so that the sliding support guide block will not fall and the sliding of the sliding support guide block will not change direction. A fixing bolt is provided on the side wall of the sliding cavity, which is used to fix the sliding support guide block so that the sliding support guide block will no longer move, thereby achieving a fixing effect. The fixing bolt is threadedly connected to the main trunk of the harvesting shovel, so that the fixing bolt can move toward the sliding support guide block after rotation, thereby facilitating the fixing of the sliding support guide block.

[0012] In one or more embodiments of the present invention, a pair of main trunk handles are fixed to the end of the harvesting shovel main trunk away from the spacer support block for workers to grasp, thereby facilitating downward pressing of the end of the harvesting shovel main trunk away from the fixed shovel, thereby allowing the fixed shovel and auxiliary shovel inserted into the soil to be tilted up, ultimately achieving the effect of harvesting asparagus.

[0013] In one or more embodiments of the present invention, a sliding support guide block is slidably disposed in the sliding cavity to support the sliding support frame, prevent the sliding support frame from falling off, and enable the sliding support frame to slide and adjust its position. The sliding support guide block is fixedly connected to the sliding support frame, so that the sliding support frame has space for adjusting its position.

[0014] The sliding support guide block is provided with a threaded groove that matches the fixing bolt, so that the staff can insert the fixing bolt into the sliding support guide block by rotating it. The fixing bolt is threadedly connected to the sliding support guide block, so that the sliding support guide block can be fixed and can no longer slide, thereby achieving the function of fixing the sliding support frame.

[0015] In one or more embodiments of the present invention, a support extrusion plate is provided in the sliding support frame for supporting the connecting column rod and also has the function of squeezing the push spring so that the push spring can be compressed, thereby generating a rebound force to facilitate the reset of the sliding support frame. One side of the support extrusion plate is fixedly connected to the connecting column rod, and the other end of the connecting column rod is fixedly connected to the spacer support block for supporting the sliding support frame to play the role of limiting support.

[0016] A pushing spring is fixedly connected between the support extrusion plate and the sliding support frame, which is used to push the sliding support frame, so that the sliding support frame can first squeeze the pushing spring when sliding, so that the pushing spring generates a rebound force, and then after the sliding support guide block is released, the sliding support frame can be reset by the pushing of the pushing spring, which facilitates the reuse of the device.

[0017] In one or more embodiments of the present invention, a limiting slider is fixed at the lower end of the sliding support frame, which is used to provide limiting support for the auxiliary shovel so that the auxiliary shovel will not fall off and will not change direction when sliding. A limiting groove matching the limiting slider is carved on the auxiliary shovel, so that the auxiliary shovel is slidably connected to the sliding support frame, thereby fixing the auxiliary shovel.

[0018] In one or more embodiments of the present invention, a pair of auxiliary shovels are fixed with a plurality of linkage rods on one end close to the fixed shovel, which are used to link the fixed shovel with the auxiliary shovel, thereby improving the fixing effect of the auxiliary shovel, preventing the auxiliary shovel from falling off during the process of shoveling the asparagus, and improving the stability of the device.

[0019] In one or more embodiments of the present invention, a buffer cavity is excavated in the fixed shovel to provide space for the sliding of the extrusion partition and the compression of the connecting spring, thereby allowing the fixed column to have a certain telescopic sliding space. The extrusion partition is slidably arranged in the buffer cavity to squeeze the connecting spring so that the connecting spring can be compressed. It also has the function of driving the fixed column to move, so that the fixed column will not fall off, and thus the linkage rod will not move again.

[0020] A fixed column is fixed on the extrusion partition for passing through the linkage rod so that the linkage rod can no longer move, thereby realizing the linkage between the fixed shovel and the auxiliary shovel, improving the fixing effect of the auxiliary shovel, and preventing the auxiliary shovel from falling off during the asparagus harvesting process. A hole matching the fixed column is bored on the linkage rod to facilitate the penetration and movement of the fixed column;

[0021] A connecting spring is fixedly connected between the extrusion partition and the fixed shovel, which is used to push the extrusion partition, so that the extrusion partition can drive the fixed column rod to pass through the linkage rod, thereby fixing the linkage rod and linking the fixed shovel and the auxiliary shovel.

[0022] In one or more embodiments of the present invention, the pad assembly includes a vertical pad, a connecting rod is fixed to the vertical pad, and is used to support the harvesting shovel trunk, so that the harvesting shovel trunk can rotate around the vertical pad and the connecting rod, thereby allowing the fixed shovel and the auxiliary shovel to tilt, making it easier to scoop up the asparagus in the soil and facilitate harvesting. The connecting rod is sleeved on the fixed shaft to facilitate the rotation of the harvesting shovel trunk;

[0023] A support shaft is fixed on the vertical pad to support the roller so that the support roller will not fall off and can rotate freely. The support shaft is rotatably connected to the support roller so that the device can be fixed by the support roller after use, thereby facilitating the movement of the harvesting shovel trunk and reducing the pressure on the handling device.

[0024] In one or more embodiments of the present invention, the fixing mechanism includes a fixed outer frame for supporting a plurality of limiting support rods and driving the limiting support rods to move, so that one of the limiting support rods is no longer inserted into the fixed socket. The fixed outer frame is fixed with a plurality of limiting support rods matching the fixing holes, which are inserted into the fixing sockets, thereby fixing the fixed shaft and the sliding support frame, so that the pad assembly no longer slides to adjust its position, thereby improving the stability of the device.

[0025] A plurality of evenly distributed support springs are fixedly connected between the fixed outer frame and the sliding guide rail, which are used to pull the limit support rod so that the limit support rod will not fall off. After the staff releases their hands, they can pull the fixed outer frame to drive the limit support rod to be inserted into the fixed socket. A pulling handle is installed on the fixed outer frame to facilitate pulling the fixed outer frame, thereby facilitating the movement of multiple limit support rods.

[0026] Compared with the prior art, the present invention enables the asparagus harvesting device to be quickly disassembled and installed through the setting of corresponding mechanisms, so that it can be disassembled when the harvester fails, thereby facilitating manual operation by the staff and avoiding delays in the asparagus harvesting progress.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0039] like Figures 1-8 As shown, a modular asparagus harvesting device that is easy to assemble and disassemble in one embodiment of the present invention includes: a harvesting shovel trunk 1, a soil shoveling component 2, a sliding support mechanism 3 and a fixing mechanism 4.

[0040] like Figures 1-4As shown, a pair of sliding cavities 101 are excavated on the harvesting shovel trunk 1 for sliding and guiding the sliding support guide block 205, preventing it from falling and preventing it from changing direction. Fixing bolts 102 are provided on the sidewalls of the sliding cavities 101 for securing the sliding support guide block 205, preventing it from moving and achieving a fixed effect. The fixing bolts 102 are threadedly connected to the harvesting shovel trunk 1, allowing the fixing bolts 102 to move toward the sliding support guide block 205 after being rotated, thereby facilitating the fixing of the sliding support guide block 205.

[0041] like Figure 1 As shown, a pair of main handles 103 are fixed to the end of the harvesting shovel main trunk 1 away from the spacing support block 201, which are used for staff to grab, so as to facilitate pressing down the end of the harvesting shovel main trunk 1 away from the fixed shovel 202, thereby allowing the fixed shovel 202 and the auxiliary shovel 203 inserted into the soil to be tilted, ultimately achieving the effect of harvesting asparagus.

[0042] like Figures 1-4 As shown, the shovel assembly 2 is mounted on the harvesting shovel trunk 1. The shovel assembly 2 includes a spacer support block 201, which is used to support a fixed shovel 202 to prevent it from falling off. It also supports a pair of connecting rods 208. The spacer support block 201 is fixedly connected to the harvesting shovel trunk 1 to prevent the spacer support block 201 and the fixed shovel 202 from falling off. The fixed shovel 202 is mounted on the spacer support block 201 and is used to be inserted into the soil and then tilted upward to harvest the asparagus in the soil.

[0043] Specifically, the fixed shovel 202 is provided with a plurality of linkage holes to facilitate the insertion of linkage rods 211, thereby enabling the fixed shovel 202 and the auxiliary shovel 203 to be linked together and secure the auxiliary shovel 203. Auxiliary shovels 203 are provided on both sides of the fixed shovel 202 to assist in scooping up the asparagus, thereby improving the efficiency of asparagus harvesting. A sliding support frame 204 is slidably connected to the auxiliary shovel 203 to support the auxiliary shovel 203 and enhance the securing effect of the auxiliary shovel 203, so that the auxiliary shovel 203 will not fall when scooping up the asparagus.

[0044] like Figures 1-4As shown, a sliding support guide block 205 is slidably disposed within the sliding cavity 101 to support the sliding support frame 204, prevent the sliding support frame 204 from falling off, and enable the sliding support frame 204 to slide and adjust its position. The sliding support guide block 205 is fixedly connected to the sliding support frame 204, allowing the sliding support frame 204 to have space for adjustment. The sliding support guide block 205 has a threaded groove that matches the fixing bolt 102, allowing a worker to insert the fixing bolt 102 into the sliding support guide block 205 by rotating it. The fixing bolt 102 is threadedly connected to the sliding support guide block 205, so that the sliding support guide block 205 can be fixed and cannot slide anymore, thereby achieving the function of fixing the sliding support frame 204.

[0045] like Figures 1-4 As shown, a support extrusion plate 206 is provided in the sliding support frame 204 for supporting the connecting column 208 and also for squeezing the push spring 207, so that the push spring 207 can be compressed, thereby generating a rebound force to facilitate the reset of the sliding support frame 204. One side of the support extrusion plate 206 is fixedly connected to the connecting column 208, and the other end of the connecting column 208 is fixedly connected to the spacer support block 201, for supporting the sliding support frame 204 and playing the role of limiting support.

[0046] Specifically, a pushing spring 207 is fixedly connected between the support extrusion plate 206 and the sliding support frame 204, which is used to push the sliding support frame 204, so that the sliding support frame 204 can first squeeze the pushing spring 207 when sliding, causing the pushing spring 207 to generate a rebound force, and then after the sliding support guide block 205 is released, the sliding support frame 204 can be reset by pushing the pushing spring 207, which facilitates the reuse of the device.

[0047] like Figures 1-4 As shown, a limit slider 209 is fixed to the lower end of the sliding support frame 204, which is used to limit and support the auxiliary shovel 203, preventing the auxiliary shovel 203 from falling off and preventing the auxiliary shovel 203 from changing direction during sliding. A limit slot 210 is excavated on the auxiliary shovel 203 to match the limit slider 209, allowing the auxiliary shovel 203 to slide in connection with the sliding support frame 204, thereby securing the auxiliary shovel 203.

[0048] like Figure 1-Figure 5 As shown, a pair of auxiliary shovels 203 are fixed with a number of linkage rods 211 at one end close to the fixed shovel 202, which are used to link the fixed shovel 202 with the auxiliary shovel 203, thereby improving the fixing effect of the auxiliary shovel 203, so that the auxiliary shovel 203 will not fall off during the process of shoveling the asparagus, thereby improving the stability of the device.

[0049] A buffer chamber 212 is excavated within the fixed shovel 202 to provide space for the sliding of the extrusion partition 214 and the compression of the connecting spring 215, thereby providing a certain amount of space for the fixed column 213 to extend and slide. A compression partition 214 is slidably arranged within the buffer chamber 212 to compress the connecting spring 215, thereby causing it to be compressed and driving the fixed column 213 to move, preventing it from falling off and thus preventing the linkage rod 211 from moving.

[0050] like Figure 1-Figure 5 As shown, a fixed post 213 is fixed to the extrusion partition 214, which is used to pass through the linkage rod 211, preventing the linkage rod 211 from moving. This allows the fixed shovel 202 to be linked with the auxiliary shovel 203, improving the fixing effect of the auxiliary shovel 203 and preventing the auxiliary shovel 203 from falling off during the asparagus harvest. The linkage rod 211 has a hole that matches the fixed post 213, facilitating the movement of the fixed post 213 through the hole.

[0051] Specifically, a connecting spring 215 is fixedly connected between the extrusion partition 214 and the fixed shovel 202, which is used to push the extrusion partition 214, so that the extrusion partition 214 can drive the fixed column rod 213 to pass through the linkage rod 211, thereby fixing the linkage rod 211, and then linking the fixed shovel 202 and the auxiliary shovel 203.

[0052] like Figures 1-6 As shown, the sliding support mechanism 3 is mounted on one side of the harvesting shovel trunk 1. The sliding support mechanism 3 includes a sliding rail 301, which provides space for the sliding support frame 302 and serves as a guide for the sliding movement. The sliding rail 301 is provided with an adjustment slot and multiple fixing holes, which allow the limiting support rod 402 to pass through. The adjustment slot houses the sliding support frame 302. A fixed shaft 303 is mounted within the sliding support frame 302, supporting the connecting rod 307 and enabling the harvesting shovel trunk 1 to rotate about a fixing hole 304, thereby facilitating the removal of asparagus from the soil and saving labor. The fixing shaft 303 is provided with a fixing hole 304 for the limiting support rod 402 to insert, thereby securing the fixing shaft 303 and the sliding support frame 302. A pad assembly 305 is rotatably connected to the fixed shaft 303.

[0053] like Figures 1-8As shown, the pad assembly 305 includes a vertical pad 306, and a connecting rod 307 is fixed on the vertical pad 306 for supporting the harvesting shovel trunk 1, so that the harvesting shovel trunk 1 can rotate around the vertical pad 306 and the connecting rod 307, thereby enabling the fixed shovel 202 and the auxiliary shovel 203 to be tilted, making it convenient to shovel the asparagus in the soil and facilitate harvesting. The connecting rod 307 is mounted on the fixed shaft 303 to facilitate the rotation of the harvesting shovel trunk 1.

[0054] Specifically, a support shaft 308 is fixed on the vertical pad 306 for supporting the roller 309 so that the support roller 309 will not fall off and can rotate freely. The support shaft 308 is rotatably connected to the support roller 309 so that the device can be fixed by relying on the support roller 309 after use, thereby facilitating the movement of the harvesting shovel trunk 1 and reducing the pressure on the carrying device.

[0055] like Figures 1-8 As shown, the fixing mechanism 4 is mounted on the sliding guide rail 301 and is used to fix the position of the sliding support frame 302, thereby preventing the spacer assembly 305 from sliding. The fixing mechanism 4 includes a fixed outer frame 401, which is used to support multiple limiting rods 402 and drive the limiting rods 402 to move, so that one of the limiting rods 402 is no longer inserted into the fixed socket 304. The fixed outer frame 401 is fixed with multiple limiting rods 402 that match the fixing holes and are inserted into the fixed socket 304, thereby fixing the fixed shaft 303 and the sliding support frame 302, preventing the spacer assembly 305 from sliding and adjusting its position, thereby improving the stability of the device.

[0056] like Figure 7-Figure 8 As shown, a plurality of evenly distributed support springs 403 are fixedly connected between the fixed outer frame 401 and the sliding guide rail 301, and are used to pull the limiting support rods 402 so that the limiting support rods 402 do not fall off. Moreover, after the staff releases their hands, they can pull the fixed outer frame 401, thereby driving the limiting support rods 402 to be inserted into the fixed sockets 304. A pulling handle 404 is installed on the fixed outer frame 401, which is used to facilitate pulling the fixed outer frame 401, thereby facilitating the movement of the plurality of limiting support rods 402.

[0057] During use, the staff first pulls the sliding support frame 204 to gradually move the sliding support frame 204 away from the spacer support block 201, and then rotates the fixing bolt 102 to thread the fixing bolt 102 into the sliding support guide block 205, thereby fixing the position of the sliding support frame 204;

[0058] Then, the limiting groove 210 on the auxiliary shovel 203 is aligned with the limiting slider 209 and inserted, so that the auxiliary shovel 203 is slidably connected to the sliding support frame 204, and the linkage rod 211 on the auxiliary shovel 203 can be inserted into the linkage hole on the fixed shovel 202. At this time, the fixed column 213 is released, and the fixed column 213 is pushed by the connecting spring 215 so that the fixed column 213 can pass through the linkage rod 211, thereby preventing the auxiliary shovel 203 from sliding, and the auxiliary shovel 203 and the fixed shovel 202 are linked together;

[0059] At this time, the staff inserts the fixed shovel 202 and the auxiliary shovel 203 into the asparagus planting field, and then presses the harvesting shovel main body 1 away from the end of the fixed shovel 202 with the center of the vertical pad 306 and the connecting sleeve 307, so that the fixed shovel 202 and the auxiliary shovel 203 can lift the asparagus.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0061] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
