Description

Technical Field

[0001] This invention relates to the field of bamboo shoot harvesting technology, and in particular to a bamboo forest bamboo shoot harvesting and digging device and its usage method. Background Technology

[0002] Badu bamboo is a common economic crop, primarily used for timber but also for shoots. Its bamboo shoots are typically large, with some edible nodes remaining below the soil. It also has a long productive period, creating a multi-faceted economic model of "short-term shoot harvesting and long-term timber harvesting," enhancing the resilience of the planting base. After the bamboo shoots emerge from the ground, manual harvesting is necessary to determine the cutting point. Harvesting bamboo shoots typically involves using hoes and other agricultural tools; however, current hoes for harvesting bamboo shoots are not suitable for loosening the soil during digging, and manual digging easily damages the bamboo shoots and rhizomes, affecting subsequent shoot yields. They also don't easily help identify the bamboo nodes, and with the bamboo shoots covered by their outer skin, it's difficult to avoid the hard, solid areas at the nodes. Traditional hoes directly and rigidly cut the bamboo shoots at the nodes, making a clean cut difficult and easily damaging the rhizomes. If the cut falls on the hard area at the base of the bamboo shoot, the excess hard root will be cut off and discarded, resulting in lower economic value. Summary of the Invention

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1 to 9 :

[0035] This invention proposes a bamboo shoot harvesting and digging device and its usage method, including a handheld component 1, on which a soil loosening component 2 is installed; the soil loosening component 2 is used to loosen the soil around the bamboo shoot; a swing control component 3 is installed on the handheld component 1; the swing control component 3 is used to adjust the cutting position; a bamboo node detection component 4 is installed on the swing control component 3; the bamboo node detection component 4 is used to indicate the bamboo node; a cutting component 5 is installed on the bamboo node detection component 4; the cutting component 5 is used to cut the bamboo shoot; the handheld component 1 includes: a handheld mounting ring 101 and swing arms 102, the handheld mounting ring 101 is provided with two handles; four swing arms 102 are rotatably mounted on the handheld mounting ring 101, the four swing arms 102 are spaced equally.

[0036] In this embodiment, the handheld component 1 further includes: a tension spring 103 and loosening teeth 104. Four tension springs 103 are provided, with their ends respectively connected between four swing arms 102. The four tension springs 103 are used to pull and gather the four swing arms 102. Loosening teeth 104 are fixedly installed on each of the four swing arms 102 by bolts, and the ends of the four loosening teeth 104 are respectively inclined structures. The loosening component 2 includes: a loosening plate 201 and a contact ball 202. The loosening plate 201 is fixedly installed on each of the four swing arms 102, and the four loosening plates 201 are used to move the soil. The contact ball 202 is fixedly installed on each of the four loosening plates 201, and the contact ball 202 is used to contact the surface of the bamboo shoot. The loosening component 2 also includes: a protective rod 203. A protective rod 203 is fixedly installed on each of the four loosening plates 201, and the four protective rods 203 are used to contact the surface of the bamboo shoot. The rods 203 are all arc-shaped structures; the ends of the four protective rods 203 are raised; the ends of the four loosening teeth 104 are higher than the bottom of the protective rods 203. The protective rods 203 are used to protect the bamboo rhizomes. The use of the loosening component 2 makes it easy to loosen the soil around the bamboo shoots, which is convenient for subsequent cutting. At the same time, this structure will not damage the bamboo shoots, avoiding the damage that is easily caused by manually digging the soil with tools such as hoes. At the same time, the protective rods 203 can protect the bamboo rhizomes, preventing the loosening teeth 104 from directly scraping the bamboo rhizomes and affecting the subsequent growth of bamboo shoots, thus maintaining the long-term yield of bamboo shoots. The structure is simple to operate for loosening the soil and can be easily adapted to different bamboo shoot diameters. The depth of the loosening soil is easy to control. As the loosening teeth 104 continue to rotate and loosen the soil, they gradually go deeper into the soil. When the protective rods 203 go deeper into the soil and approach the bamboo rhizomes, the raised ends of the protective rods 203 can slide directly over the upper surface of the bamboo rhizomes, avoiding scratching the bamboo rhizomes.

[0037] In this embodiment, the swing control component 3 includes: a cutting mounting arm 301, a lower pressure plate 302, and an indicator light 303. The cutting mounting arm 301 is rotatably mounted on the handheld mounting ring 101; the lower pressure plate 302 is fixedly mounted on the cutting mounting arm 301, and a rubber pad is provided on the lower pressure plate 302; the indicator light 303 is fixedly mounted on the lower pressure plate 302; the end of the cutting mounting arm 301 is located above the four loosening teeth 104; the swing control component 3 also includes: a reset spring 304, one end of which is fixedly mounted on the cutting mounting arm 301; the other end of the reset spring 304 is fixedly mounted on the bottom of the handheld mounting ring 101; the bamboo joint detection component 4 includes: a detection mounting cylinder 40 1. A rear cover 4011, a sliding post 402, and a return spring 403 are included. The detection mounting cylinder 401 is fixedly mounted at the bottom end of the cutting mounting arm 301. The detection mounting cylinder 401 has a hexagonal hole. The rear cover 4011 is fixedly mounted on the detection mounting cylinder 401. The rear cover 4011 has a wire-passing hole for passing wires. The sliding post 402 is slidably mounted on the detection mounting cylinder 401, and the sliding post 402 has a hexagonal column structure. A return spring 403 is sleeved inside the detection mounting cylinder 401. One end of the return spring 403 is fixedly mounted on the rear cover 4011. The other end of the return spring 403 is fixedly mounted on the tail of the sliding post 402. The bamboo joint detection component 4 also includes: a control switch 40. 4. The control switch 404 is fixedly installed on the rear cover 4011; the control switch 404 is located behind the sliding column 402; the control switch 404 is electrically connected to the indicator light 303. Using the bamboo joint detection component 4 in conjunction with the swing control component 3, it is possible to quickly control the cutting component 5 to rotate around the outside of the bamboo shoot for ring cutting, resulting in a smooth cut surface. This avoids the tendency to create a tilted cut when using tools such as hoes. Furthermore, if the cutting position is at a bamboo joint, the resistance increases when using tools such as hoes due to the hardness of the joint, potentially damaging the bamboo rhizome. This structure utilizes the bamboo joint detection component 4 to facilitate workers in checking the cutting position and ensuring the cutting blade 501 maintains its cutting position. The lower hardness area between bamboo nodes facilitates inspection of the hard areas at the base of the bamboo shoot, avoiding unnecessary removal of hard areas. The structural inspection is simple, utilizing the hard and solid characteristics of the bamboo nodes of Badu bamboo shoots for quick inspection. When the pressure plate 302 is pressed down, the cutting blade 501 is pressed against the hard bamboo node or base of the bamboo shoot. The bamboo shoot is harder in this area, and the cutting blade 501 cannot be inserted. When the pressure plate 302 is pressed down, the cutting blade 501 is stopped by the bamboo node, causing the sliding column 402 to retract and compress the return spring 403. At this time, the sliding column 402 will press the control switch 404, and the indicator light 303 will light up as a warning.

[0038] In Example 2, based on Example 1, the cutting component 5 includes: a cutting blade 501 and a positioning bolt 502. The cutting blade 501 is inserted into the sliding column 402; the positioning bolt 502 is threaded onto the sliding column 402; the positioning bolt 502 passes through the cutting blade 501. The use of the positioning bolt 502 facilitates the disassembly and replacement of the cutting blade 501, improves the ease of replacement of the cutting blade 501, and ensures that the cutting blade 501 can remain sharp.

[0039] How to use a bamboo shoot harvesting and digging device in a bamboo forest:

[0040] 1) Manually hold the two handles on the installation ring 101 and place the four loosening boards 201 on the outside of the bamboo shoot;

[0041] 2) Manually press down on the handheld installation ring 101 to make the loosening plate 201 fit into the soil. Rotate the handheld installation ring 101 to make the loosening plate 201 rotate, and work with the loosening teeth 104 to loosen the soil around the bamboo shoot.

[0042] The working principle of this embodiment is as follows: First, when digging and loosening the soil around the bamboo shoot, the operator holds the two handles on the mounting ring 101 and places the four loosening plates 201 on the outside of the bamboo shoot. At this time, under the pull of the four tension springs 103, the contact ball 202 will contact the outside of the bamboo shoot and press down the loosening plate 201. Rotating the hand-held mounting ring 101 will drive the loosening plate 201 to rotate. With the cooperation of the loosening teeth 104, the soil around the bamboo shoot can be loosened. As the loosening teeth 104 continue to rotate and loosen the soil, they gradually go deeper into the soil. When the protective rod 203 goes deeper into the soil and gets close to the bamboo rhizome, the end of the protective rod 203 is raised and can slide directly over the upper surface of the bamboo rhizome. The lower surface of the protective rod 203 is lower than the end of the loosening teeth 104 to avoid the loosening teeth 104 directly scratching the bamboo rhizome.

[0043] After loosening the soil and removing the outer layer of the bamboo shoot, the operator can manually press down the pressure plate 302, causing the cutting mounting arm 301 to rotate on the handheld mounting ring 101. The end of the cutting mounting arm 301 then moves the cutting blade 501 close to and presses against the surface of the bamboo shoot. Because the area between the bamboo nodes is relatively soft and has a hollow structure, the return spring 403 will not be compressed. At this point, the cutting blade 501 can be inserted into the area between the bamboo nodes. The handheld mounting ring 101 can then be rotated to make the cutting blade 501 rotate around the bamboo shoot, cutting it. Conversely, if the pressure plate 302 is pressed down, causing the cutting blade 501 to press against the hard bamboo nodes or the root of the bamboo shoot, where the bamboo shoot is harder, the cutting blade 501 will not be able to cut it. When the pressure plate 302 is pressed down, the cutting blade 501 is stopped at the bamboo joint, causing the sliding column 402 to retract and compress the return spring 403. At this time, the sliding column 402 will press the control switch 404, and the control indicator light 303 will light up to indicate that cutting is not possible at this point. In actual operation, when cutting bamboo shoots, the operator can gradually lift the cutting blade 501 and switch the inspection position until the cutting blade 501 can be inserted into the bamboo shoot for cutting. When the cutting blade 501 needs to be replaced, the positioning bolt 502 can be removed by turning with a wrench. After the new cutting blade 501 is inserted into the sliding column 402, the positioning bolt 502 is passed through the cutting blade 501 and tightened on the sliding column 402.
