Description

Technical Field

[0001] This utility model belongs to the field of coltsfoot harvesting technology, and relates to a digging shovel for digging coltsfoot, especially a labor-saving digging shovel for digging coltsfoot. Background Technology

[0002] Coltsfoot, also known as winter flower or coltsfoot, is a plant belonging to the Apiaceae family in botany. Coltsfoot is a plant with ornamental and medicinal value, suitable for use in horticulture and traditional Chinese medicine. Coltsfoot is usually harvested manually by workers using a digging shovel, but most of the digging shovels used for digging coltsfoot still have problems that need to be solved when in use.

[0003] Most existing digging tools for plucking coltsfoot have simple structures and are labor-intensive to use. They cannot assist in digging and require workers to expend a lot of physical strength to dig up the soil and coltsfoot together. The lack of digging assistance makes it difficult for workers to use mechanical force during the digging process, increasing labor intensity and making them prone to fatigue and injury. Therefore, it is necessary to design a labor-saving digging tool for plucking coltsfoot to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a labor-saving digging shovel for digging coltsfoot flowers. The technical problem to be solved by this utility model is: how to dig coltsfoot flowers more labor-savingly.

[0005] The objective of this utility model can be achieved through the following technical solutions: A labor-saving digging shovel for harvesting coltsfoot flowers includes a shovel with a fixed sleeve. A connecting block is rotatably connected to the fixed sleeve. A fixed rod is fixedly connected to one side of the connecting block. A fixed plate is fixedly connected to the fixed rod on the side away from the connecting block. A plurality of equally spaced pins are fixedly connected to the fixed plate on the side away from the fixed rod. A limiting block is fixedly connected to the outer wall of the fixed rod. A limiting groove is formed on the limiting block. A trapezoidal block is provided in the limiting groove. The trapezoidal block has an inclined surface on the side near the fixed rod and an arc surface on the side away from the fixed rod. A round rod is fixedly connected to the top of the trapezoidal block. The shovel has a fixed block. Two limiting rods are fixedly connected to the bottom of the fixed block. The two limiting rods are fitted with the same sleeve plate. The sleeve plate is slidably connected to the limiting rods. A round rod is fixedly connected to the bottom of the sleeve plate. A spring is fitted on the limiting rod. The spring is disposed between the sleeve plate and the fixed block.

[0006] The working principle of this utility model is as follows: When digging up coltsfoot flowers, the shovel is inserted into the soil, and then the trapezoidal block is raised. Moving the trapezoidal block out of the limiting groove releases the restriction on the limiting block, allowing the fixing rod to rotate around the connection point of the fixing sleeve and connecting block. This allows adjustment of the position of the fixing plate and the pin. The fixing plate is placed on the soil, and the user steps on it to insert the pin into the soil, improving stability. Pressing down on the shovel then uses the fixing rod, fixing plate, and pin as fulcrums, utilizing the lever principle to dig out the soil and the coltsfoot flowers. Compared to the traditional method of shoveling up the soil and flowers, this method is more labor-saving. After completing all the digging work, the fixing rod, fixing plate, and pin are again positioned around the connection point of the fixing sleeve and connecting block. The connection point is the center of the circle. When the arc surface of the limiting block contacts the inclined surface of the trapezoidal block, if the limiting block continues to move, the trapezoidal block will rise. The trapezoidal block will drive the round rod to rise, and the round rod will drive the sleeve plate to move along the limiting rod, ensuring the stability of the trapezoidal block during movement. The rising of the sleeve plate will also compress the spring, causing the spring to contract. When the trapezoidal block is in the position of the limiting groove, the contracted spring will extend, which will cause the sleeve plate to fall. The sleeve plate will drive the round rod to fall, and the round rod will drive the trapezoidal block to fall, so that the round rod is locked into the limiting groove, thus restricting the position of the limiting block. This fixes the position of the limiting block, fixing rod, fixing plate, and pin, and allows for the storage of the fixing rod, fixing plate, and pin, reducing the space occupied and facilitating transportation and storage.

[0007] As a further embodiment of this utility model, the shovel includes a shovel handle, a shovel head is fixedly connected to the bottom of the shovel handle, and a grip is fixedly connected to the top of the shovel handle.

[0008] As a further embodiment of this utility model, the shovel handle is fixedly connected to a fixing sleeve and a fixing block, with the fixing block located at the end of the shovel handle away from the shovel head.

[0009] As a further embodiment of this utility model, a plurality of serrated cutting edges are fixedly connected to the blade of the shovel head.

[0010] By adopting the above structure and setting serrated cutting edges, the soil cutting resistance is reduced, allowing the shovel head to be inserted into the soil more effortlessly.

[0011] As a further embodiment of this utility model, a U-shaped block is fixedly connected to the top of the sleeve plate, a pull rope is provided on the U-shaped block, and a handle is fixedly connected to the top of the pull rope.

[0012] With the above structure, pulling the handle will cause the pull rope to move, which in turn causes the U-shaped block to move, which in turn causes the sleeve plate to move, thus moving the trapezoidal block out of the limiting groove.

[0013] As a further embodiment of this utility model, the pull rope is fitted with a support block, the support block has a round hole, and the pull rope is disposed in the round hole on the support block.

[0014] As a further embodiment of this utility model, the support block is fixedly connected to the outer wall of the end of the shovel handle away from the shovel head.

[0015] Compared with the prior art, the labor-saving digging shovel of this utility model has the following advantages: In this invention, a lever principle is used to excavate coltsfoot flowers by employing a fixed rod, a fixed plate, and a nail as fulcrums. During the excavation process, the nail is inserted into the soil to improve stability. The digging shovel, with the fixed rod, fixed plate, and nail as fulcrums, forms a force-saving lever, amplifying the applied force. Pressing the digging shovel allows for easier excavation of the soil and the coltsfoot flowers. Furthermore, the use of limiting blocks, limiting grooves, and trapezoidal blocks restricts the position of the fixed rod, fixed plate, and nail, preventing movement during transport and facilitating efficient transportation. The present invention addresses the shortcomings of existing technologies, such as those described in the background section, which often employ simple, labor-intensive digging tools for harvesting coltsfoot. These tools lack auxiliary digging capabilities, requiring workers to expend considerable physical effort to excavate the soil and coltsfoot together. The lack of such auxiliary digging features hinders the use of mechanical force, increasing labor intensity and increasing the risk of fatigue and injury. The present invention, however, allows workers to dig more easily, reducing physical exertion and labor intensity. It enables workers to excavate soil and coltsfoot more efficiently, shortening operation time and improving work efficiency. Attached Figure Description

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1-5 As shown, a labor-saving digging shovel for digging coltsfoot flowers includes a digging shovel 1. A fixing sleeve 2 is provided on the digging shovel 1. A connecting block 3 is rotatably connected to the fixing sleeve 2. A fixing rod 4 is fixedly connected to one side of the connecting block 3. A fixing plate 5 is fixedly connected to the fixing rod 4 on the side away from the connecting block 3. Several equally spaced pins 6 are fixedly connected to the fixing plate 5 on the side away from the fixing rod 4. A limiting block 7 is fixedly connected to the outer wall of the fixing rod 4. A limiting groove 8 is formed on the limiting block 7. A trapezoidal block 9 is provided in the limiting groove 8. The trapezoidal block 9 has an inclined surface on the side near the fixing rod 4, and an arc surface on the side away from the fixing rod 4. A round rod 10 is fixedly connected to the top of the trapezoidal block 9. A fixing block 11 is provided on the digging shovel 1. Two limiting rods 12 are fixedly connected to the bottom of the fixing block 11. The two limiting rods 12 are fitted with the same sleeve plate 13, and the sleeve plate 13 is slidably connected to the limiting rods 12. A round rod 10 is fixedly connected to the bottom of the sleeve plate 13. A spring 14 is sleeved on the limiting rod 12. The spring 14 is located between the sleeve plate 13 and the fixing block 11. The shovel 1 includes a shovel handle 101. A shovel head 102 is fixedly connected to the bottom of the shovel handle 101. A handle 103 is fixedly connected to the top of the shovel handle 101. A fixing sleeve 2 and a fixing block 11 are fixedly connected to the shovel handle 101. The fixing block 11 is located at the end of the shovel handle 101 away from the shovel head 102. Several serrated cutting edges 1021 are fixedly connected to the shovel blade of the shovel head 102. A U-shaped block 15 is fixedly connected to the top of the sleeve plate 13. A pull rope 16 is provided on the U-shaped block 15. A handle 17 is fixedly connected to the top of the pull rope 16. A support block 18 is sleeved on the pull rope 16. A round hole is opened on the support block 18. The pull rope 16 is located in the round hole on the support block 18. The support block 18 is fixedly connected to the outer wall of the end of the shovel handle 101 away from the shovel head 102.

[0020] The working principle of this utility model is as follows: When digging up coltsfoot flowers, the shovel head 102 is inserted into the soil, and the handle 17 is pulled. The handle 17 will move the pull rope 16, which will move the U-shaped block 15. The U-shaped block 15 will move the sleeve plate 13, thus moving the trapezoidal block 9 out of the limiting groove 8, releasing the restriction on the limiting block 7. This allows the fixing rod 4 to rotate around the connection point between the fixing sleeve 2 and the connecting block 3, thereby adjusting the position of the fixing plate 5 and the pin 6. The fixing plate 5 is placed on the soil, and the user steps on the fixing plate 5 to... Inserting the nail 6 into the soil improves stability. Pressing the handle 103 then allows the soil and coltsfoot flowers to be dug out using the fixing rod 4, fixing plate 5, and nail 6 as fulcrums. The fixing sleeve 2 is positioned at the end of the shovel handle 101 near the shovel head 102. At this point, using the fixing sleeve 2 as a dividing point, the distance between the fixing sleeve 2 and the shovel head 102 is shorter than the distance between the fixing sleeve 2 and the handle 103. Utilizing the lever principle, this method digs out the soil and the coltsfoot flowers within it. Compared to the traditional method of forcefully shoveling up the soil and flowers, this method is more labor-saving. After completing all the work of digging out the coltsfoot flowers... If the fixing rod 4, fixing plate 5, and pin 6 are moved in a circular motion around the connection between fixing sleeve 2 and connecting block 3, and the limiting block 7 continues to move when its arc surface contacts the inclined surface of trapezoidal block 9, trapezoidal block 9 will rise. Trapezoidal block 9 will then drive round rod 10 to rise, and round rod 10 will drive sleeve 13 to move along limiting rod 12, ensuring the stability of trapezoidal block 9 during movement. The rising sleeve 13 will also compress spring 14, causing it to contract. When trapezoidal block 9 is in the position of limiting groove 8, the contracted spring 14 will... When extended, the sleeve 13 can be lowered, which in turn lowers the round rod 10, which in turn lowers the trapezoidal block 9, causing the round rod 10 to engage with the limiting groove 8. This restricts the position of the limiting block 7, thus fixing the limiting block 7 and securing the positions of the fixing rod 4, fixing plate 5, and pin 6. The fixing rod 4, fixing plate 5, and pin 6 can be stored away, reducing the space occupied and facilitating transportation and storage. By setting the serrated cutting edge 1021, the soil cutting resistance is reduced, allowing the shovel head 102 to be inserted into the soil more effortlessly.

[0021] In summary, this invention allows workers to excavate more easily, reducing physical exertion and effectively lowering the labor intensity of the workers. It also enables workers to excavate soil and coltsfoot more efficiently, shortening the operation time and improving work efficiency.
