[0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the handicraft market is becoming increasingly mature. Gourd handicrafts, as one of them, have even become a national intangible cultural heritage. For example, gourd carving. In order to inherit intangible cultural heritage, many places have carried out interest cultivation activities based on this, attracting a large number of teenagers and even children to make gourd handicrafts. On the basis of inheriting traditional craftsmanship, they continue to innovate and present a rich and colorful art form.

[0003] In the production of gourd handicrafts, removing the gourd pulp is a key pre-processing step, but traditional tools have significant drawbacks: for example, using ordinary metal knives / wire tools, because these tools have sharp edges, children are likely to cut their hands or puncture the gourd wall when operating them; the surface of the gourd is smooth, making it difficult to hold and easy to slip and cause accidental injury when applying force, posing a safety hazard. Because the inner cavity of the gourd has an irregular curved surface, ordinary straight-handled tools have difficulty reaching the corners, resulting in a large amount of flocculent pulp remaining. The residue is prone to mold, affecting subsequent processes (such as pyrography and carving), and may even cause the finished product to crack, resulting in low cleaning efficiency and incomplete cleaning.

[0004] Tools are not suitable for children's abilities: Adult tools (such as long-handled scrapers) are too large and heavy, making them difficult for children to hold; they require strong pressing and rotation, which children lack the strength to handle, leading to fatigue and poor results.

[0005] Therefore, there is an urgent need to design a safe and effective tool for removing the inner shell of a gourd. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] This embodiment provides a manual hoist de-pickle device, including a bracket, a fixed plate, a bearing, a main shaft, a scraper assembly, and a scraper telescopic mechanism; the bracket includes at least three adjustable telescopic legs and a fixed plate disposed on the top, with a bearing disposed at the center of the fixed plate; The outer ring of the bearing is connected to the fixed disk, and the inner ring of the bearing is provided with a main shaft. A locking mechanism is provided between the inner ring of the bearing and the main shaft. The locking mechanism includes a first elastic pin and a first pin hole. The first elastic pin is provided on the inner ring of the bearing, and the first pin hole is provided on the main shaft. The first elastic pin and the first pin hole cooperate to realize the position of the main shaft in the bearing. Under the action of external force, when the main shaft passes through the inner ring at different positions, it cooperates with the first elastic pin on the inner ring and the first pin hole at different times to fix the main shaft of different lengths. The main shaft is provided with a through bearing, and the bottom end of the main shaft is connected to a scraper assembly; the scraper assembly is provided with a scraper blade for scraping the gourd ladle; the shape of the scraper blade matches the inner wall of the gourd, and the scraper blade telescopic mechanism changes the position of the scraper blade by telescopic movement. When the scraper blade telescopic mechanism is extended, the scraper blade matches the inner cavity of the gourd. The scraper telescopic mechanism in this embodiment includes a sliding member, a drive rod, a support rod, and a base cylinder. The sliding member is movably mounted on the main shaft. One end of the drive rod is mounted on the sliding member, and the other end is connected to the scraper. The base cylinder is located at the lower end of the main shaft, and a support rod is provided between the base cylinder and the drive rod. When the sliding member moves along the main shaft, the drive rod rotates around the connection point with the support rod. When the drive rod extends, the scraper extends, thereby adjusting the position of the scraper. An adjustment assembly is provided on the main shaft; the adjustment assembly is used to change the position of the sliding member; the adjustment assembly includes an adjustment rod disposed in the channel of the main shaft, the adjustment rod is provided with a second elastic pin, and the main shaft is provided with a second pin hole, which cooperates with the second elastic pin to limit the position of the adjustment rod in the channel of the main shaft; under the action of external force, when the adjustment rod passes through different positions in the channel of the main shaft, the second elastic pin cooperates with different second pin holes to fix the adjustment rod at different positions; The sliding component of the scraper telescopic mechanism changes the position of the scraper through the drive rod under the action of external force, so as to match the inner wall of the hoist: when driven downward, the scraper can be opened in a spreading state, and when moved upward, the scraper can be contracted in a tightening state. In this embodiment, the scraper telescopic mechanism changes the scraper position in the following way: when the sliding member is pressed down, the drive rod is driven to push the scraper, so that the scraper extends to the inner wall of the gourd. The support rod is an elastic rod, and the scraper is an arc-shaped scraper that matches the gourd wall. Under the combined action of the drive rod and the support rod, the scraper is tightly attached to the inner wall of the gourd, which can scrape the scoop inside the gourd clean.

[0028] In this embodiment, a slot is provided on the main shaft. The slot is used to accommodate the support rod. When the slider moves upward, the support rod moves close to the main shaft and is folded and stored in the slot. In this embodiment, the scraper is a nickel-titanium alloy sheet (thickness 0.4mm) with a pre-bending radius of 30-80mm.

[0029] In this embodiment, the fixed disk is equipped with an angle scale and a pointer, and the pointer rotates synchronously with the spindle.

[0030] In this embodiment, the adjustable telescopic outrigger adopts a three-stage sleeve structure, with the sleeves fixed together by wing bolts, and the adjustment range is 50-400mm.

[0031] In this embodiment, the core function of the angle scale on the fixed plate is to achieve precise positioning and process control. It is used to indicate the scraping path and realize the visual control of the scraping process. The angle scale displays the rotation angle of the main shaft. By observing the pointer position, the operator controls the blade to evenly cover the inner cavity of the gourd to avoid missing areas, thus overcoming the traditional blind scraping and missing scraping. This embodiment also includes a crank handle: the crank handle is disposed on the upper part of the main shaft and cooperates with the main shaft to rotate the main shaft. The crank handle is used to drive the main shaft to rotate under the action of external force; thereby driving the scraper to rotate and scrape off the inner scoop of the gourd.

[0032] An LED light is installed at the base of the scraper head. The LED light is powered by a button battery and is used to illuminate the inside of the gourd.

[0033] The manual gourd pith removal device provided in this embodiment can be operated in the following manner: First, place the gourd under the fixed plate and stand it under the support. Adjust the height of the telescopic legs so that the main shaft can reach the bottom of the gourd's inner cavity. Then, insert the scraper assembly into the gourd from the opening with the scraper in the retracted state. Adjust the position of the main shaft and the adjusting rod so that the extended scraper blade contacts the inner wall of the gourd. Then, select the crank handle and rotate the main shaft so that the main shaft rotates around the bearing, thereby scraping off the gourd pulp corresponding to the scraper blade position on the inner wall of the gourd. Then, readjust the position of the main shaft and the adjusting rod and repeat the process until all the gourd pulp is scraped off. When the crank handle is rotated, you can hear a "rustling" sound, indicating that the pulp is peeling off. Finally, retract and remove the scraper assembly, pour out the pulp debris, and rinse with clean water.

[0034] During the scraping process, the angle scale and pointer set on the fixed plate can be used to display the progress. Since the pointer rotates synchronously with the main shaft, the position of the pointer indicates the position of the scraper. The progress can also be observed by illuminating the inside of the hoist with LED lights.
