Description
Technical Field
[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an auxiliary device for harvesting scallions. Background Technology
[0002] Onions are an indispensable ingredient in people's daily lives, and they also have certain health and medicinal value. As a result, they are produced as an agricultural product in various regions to supply the market. In northern my country, scallions are mainly cultivated. During the harvest season, they are usually harvested manually or mechanically. Specifically, a shovel is inserted from one side of the scallion ridge to the scallion roots, the soil is turned over to the furrow to expose the scallion roots, and the scallion is gently pulled out from the turned side of the ridge. However, during the harvesting process, pulling or yanking the scallions will damage their pseudostems. Scallions with broken stems or damaged or broken roots will have poor quality and storage life. Because the soil in the inventor's region contains sand and gravel, using a conventional shovel, with its shovel-shaped hoe section, results in excessive pressure and effort when shoveling into the soil, making it unsuitable for use. Furthermore, the hoe section is prone to deformation, affecting its lifespan. Additionally, scallions in the inventor's region do not have a market price advantage, so the yield is mainly used to meet local consumption needs, resulting in a small planting area. Manual harvesting is time-consuming and labor-intensive, while modern mechanized harvesting is too costly and uneconomical. Therefore, developing a tool that is both practical and inexpensive to manufacture is necessary. Summary of the Invention

[0016] 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 embodiments of the present invention, and not all embodiments. Based on the 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.
[0017] Example 1, please refer to the appendix Figure 1 As shown, in one embodiment of the present invention, an auxiliary device for harvesting scallions includes a crossbeam 1, a vertical beam 2, a connecting lug 3, and a scallion shovel 5; the end of the crossbeam 1 is connected to the scallion shovel 5, the upper part of which is connected to the vertical beam 2, and the scallion shovel 5 is located below the crossbeam 1; the connecting lug 3 for connecting a traction device is fixed on the vertical beam 2.
[0018] This auxiliary device for harvesting scallions can harvest scallions. During operation, after the traction device is connected to the connecting ear 3, the angle of the shovel 5 is further adjusted to form a certain angle with the ground so that it penetrates the soil. The depth of penetration should be at the root system of the scallion. Then, the auxiliary device is pulled in the field, causing the scallions to be scooped out of the soil and fall behind the shovel 5. The soil around the roots of the scallions can then be manually cleaned and collected. This auxiliary device can be adjusted according to the attached... Figure 1 Because of its simple structure and lack of numerous parts, it is easy to assemble and has low cost, making it economical. Therefore, it is suitable for daily use by agricultural workers in the inventor's region where scallions do not have a market price advantage. It requires very little investment and can be used for simple agricultural tasks such as tilling the land.
[0019] Example 2, please refer to the appendix Figure 1-3 As shown, in one embodiment of the present invention, the scallion shovel 5 includes a left scallion shovel 51; the left scallion shovel 51 is connected to the left end of the crossbeam 1 via a left scallion shovel connecting block 52, and its soil-shoveling part has a fang-like structure with multiple evenly distributed sharp teeth. Please refer to the attached drawing. Figure 3 As shown, the sharp tooth is shaped such that its right end is machined into a bevel, and an arc-shaped groove with an arc radius of R is formed on its bevel.
[0020] The fang-like sharp teeth structure is machined on the scallion shovel 5. Because it is a whole, it has good rigidity and can be used for a long time, making it suitable for harvesting in the sandy and gravelly soil of the inventor's region. Since the sloping sharp teeth have a good shoveling angle, they can easily shovel into the soil even on sandy and gravelly soil and reach the roots of the scallion smoothly. Furthermore, the arc-shaped groove with an arc of R on its sloping surface further improves the soil cutting performance during the shoveling process, reducing the stress between the soil and the sloping surface, which further improves the problem of tooth breakage.
[0021] Example 3: As a specific implementation of the above embodiment, the vertical beam 2 includes a left vertical beam 21, a right vertical beam 22, a rear vertical beam 23, and a vertical beam support beam 24; the left vertical beam 21 and the right vertical beam 22 are symmetrically and obliquely close together and fixedly disposed at the upper middle position of the horizontal beam 1; the front end of the vertical beam support beam 24 is fixedly connected to the middle position behind the horizontal beam 1; the upper end of the rear vertical beam 23 is obliquely close together and fixedly disposed at the rear position behind the left vertical beam 21 and the right vertical beam 22, and its lower end is fixedly connected to the rear end of the vertical beam support beam 24.
[0022] The left vertical beam 21, right vertical beam 22, rear vertical beam 23, and vertical beam support beam 24 form a triangular stability structure to create a reliable connection with the traction device.
[0023] Example 4: As a specific implementation of the above embodiment, the upper ends of the left vertical beam 21 and the right vertical beam 22 are fixedly connected to a vertical beam connecting plate 4; the vertical beam connecting plate 4 includes a first vertical beam connecting plate 41 and a second vertical beam connecting plate 42, the first vertical beam connecting plate 41 being located at the upper ends of the left vertical beam 21 and the right vertical beam 22, and the second vertical beam connecting plate 42 being located behind the upper ends of the left vertical beam 21 and the right vertical beam 22; then the upper end of the rear vertical beam 23 is connected to the upper ends of the left vertical beam 21 and the right vertical beam 22 through the second vertical beam connecting plate 42, and the left vertical beam 21 and the right vertical beam 22 are connected through the first vertical beam connecting plate. 41 connection; a third left connecting ear 35 and a third right connecting ear 36 are fixedly installed on the top of the first vertical beam connecting plate 41; a first left connecting ear 31 and a first right connecting ear 32 are fixedly installed on the front of the left vertical beam 21, and a second left connecting ear 33 and a second right connecting ear 34 are fixedly installed on the front of the right vertical beam 22; the first left connecting ear 31, the first right connecting ear 32, the second left connecting ear 33, the second right connecting ear 34, the third left connecting ear 35 and the third right connecting ear 36 are all provided with mounting holes that match the traction device.

[0025] Example 5: As a specific implementation of the above embodiment, the right end of the crossbeam 1 is connected to a right scallion shovel 53 via a right scallion shovel connecting block 54, and the right scallion shovel 53 has the same structure as the left scallion shovel 51.
[0026] The right scallion shovel 53 and the left scallion shovel 51 set at both ends of the crossbeam 1 realize the harvesting scene of scallions on both sides of the field.
