Description

Technical Field

[0001] The present application relates to the technical field of agricultural seedling transplanting, and in particular to a ridge digging machine. Background Art

[0002] Transplanting seedlings (such as tobacco, saplings, medicinal materials, etc.) is a complex process involving multiple links, mainly including variety selection, transplanting planning, field management, and pest and disease control. Before transplanting, the land needs to be prepared, including tilling, fertilizing, and digging holes. When transplanting, attention should be paid to the reasonable arrangement of row spacing, spacing, and transplanting depth to ensure that the seedlings can grow and develop well. At present, in order to ensure the spacing of transplants and avoid the impact of the low temperature environment at night on the seedlings, it is usually necessary to dig holes in advance on the ridges after plowing, so that the spacing between adjacent transplant holes is basically equal. After the digging is completed, the spacing of the seedlings can be ensured by directly transplanting in each hole, and then the film covering operation can be used to ensure the low temperature damage to the seedlings in the low temperature environment at night.

[0003] At present, the main mechanical nest digging equipment is a spiral blade nest digging machine, which can quickly realize the nest digging operation through mechanical drive. The nests dug by this type of nest digging machine usually have a large inner diameter and depth. They are often used to plant large fruit trees, but are not suitable for digging nests for transplanting smaller seedlings. At the same time, the spiral nest digging machine needs to transfer it to the next nest digging point after completing a nest, which is not conducive to continuous nest digging operations. Therefore, the nests currently used for transplanting seedlings are usually dug manually using a hoe (such as Figure 1 As shown in the figure), it not only has low working efficiency and increased operating costs, but also the spacing between the pits is difficult to accurately ensure. Summary of the invention

[0004] In response to the above-mentioned problems, the present application aims to provide a ridge digging machine, which can continuously form spaced nests through the traction of agricultural machinery, and the dug nests have consistent nest spacing, thereby solving the current problems of low operating efficiency and insufficient nest spacing when manually digging nests using hoes.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a ridge digging machine, characterized in that: the digging machine includes a rotating mechanism arranged along the length direction of the ridge body, and a digging body that is in contact with and supported by the ridge body and can extend to a certain depth in the ridge body is arranged on the rotating mechanism at a designed hole spacing, and a traction mechanism is also arranged on the rotating mechanism to drive it to roll along the length direction of the ridge body.

[0006] Preferably, the rotating mechanism is a rotating cylinder; and the digging body is a digging shovel arranged at intervals on the circumference of the rotating cylinder.

[0007] Preferably, the cross section of the shovel is an arc-shaped groove structure.

[0008] Preferably, a protrusion opposite to the arc-shaped groove structure is provided near the bottom end of the shovel, and a spreading groove obliquely facing outwards is formed between the two sides of the protrusion and the edge of the shovel.

[0009] The beneficial effect of the present application is that when the nest digging machine is in the nest digging operation, the rotating mechanism is driven to rotate along the length direction of the ridge body, and the digging body drives the soil matrix in the ridge body to the outside of the ridge body, thereby continuously forming a spacing nest. The adjacent digging bodies are arranged according to the designed nest spacing, so the nests dug continuously have a consistent nest spacing, thereby solving the problem of low working efficiency and unguaranteed nest spacing when digging nests manually using a hoe.

[0010] The traction mechanism can be used to connect the rotating mechanism to agricultural machinery (such as a walking tractor), which can pull the rotating mechanism to move continuously along the length direction of the ridge body, thereby achieving continuous and consistent digging operations through the digging body.

[0019] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0020] See attached Figures 1 to 7A ridge body hole digging machine is shown, which includes a rotating mechanism arranged along the length direction of the ridge body, and a digging body that is in contact with and supported by the ridge body and can be inserted into the ridge body to a certain depth is arranged on the rotating mechanism at a designed hole spacing. During the hole digging operation, the rotating mechanism is driven to rotate along the length direction of the ridge body, and multiple digging bodies on the rotating mechanism rotate together, and the digging bodies are inserted into the ridge body by using the rotating mechanism and the body weight of the digging body. During the movement of the rotating mechanism, multiple digging bodies are successively extended into the ridge body and separated from the ridge body. During the process of separating from the ridge body, the soil matrix in the ridge body is driven to the outside of the ridge body by the digging body, thereby continuously forming spaced holes. The adjacent digging bodies are arranged according to the designed hole spacing, so that the continuously dug holes have a consistent hole spacing, thereby solving the problems of low working efficiency and unguaranteed hole spacing when digging holes manually using hoes.

[0021] In order to realize continuous hole digging operation, a traction mechanism is also provided on the rotating mechanism to drive it to roll along the length direction of the ridge body. The rotating mechanism can be connected to agricultural machinery (such as a walk-behind tractor) through the traction mechanism, which can pull the rotating mechanism to move continuously along the length direction of the ridge body, thereby realizing continuous hole digging operation with consistent hole spacing through the digging body.

[0022] Specifically, Figure 2 , 4 -5, the rotating mechanism is a rotating cylinder 1; the digging body is a digging shovel 2 arranged at intervals on the circumference of the rotating cylinder 1. The traction mechanism is preferably a traction rod 3 connected to the rotating shaft of the rotating cylinder 1, and the traction rod is connected to the agricultural machinery. Through the drive of the agricultural machinery, the rotating cylinder 1 can be towed to continuously move along the length of the ridge body on the basis of the support of the digging shovel 2. Figure 5 As shown, during the process of pulling the rotating cylinder 1, multiple shovels 2 are alternately contacted with the ridge body in turn to support the rotating cylinder 1. At the same time, relying on the weight of the rotating cylinder 1 and the shovels 2, the shovels 2 in contact with the ridge body are inserted to a certain depth in the ridge body, and the currently inserted shovels 2 are displaced and separated from the outside of the ridge body again as the rotating cylinder 1 moves. During the separation process, a certain amount of soil matrix in the ridge body is driven (planed) to the outside of the ridge body through the surface of the shovel 2, thereby forming a nest, as shown in FIG. Figure 4 As shown. With the continuous traction of the agricultural machinery, multiple shovels 2 can be used to continuously dig out nests with uniform spacing on the ridge body, such as Figure 5 shown.

[0023] Since the soil matrix thrown out by the shovel 2 is in a loose state, the soil matrix is ​​easily separated from both sides of the shovel 2 during the process of the shovel 2 driving the soil matrix ( Figure 3 As shown by the arrow in the middle, the soil matrix falls into the newly dug nest again to achieve landfill, resulting in insufficient depth of the dug nest. To solve this problem, Figure 3As shown, the cross-section of the shovel 2 is an arc-shaped groove structure, which can gather the soil matrix dug out by the shovel 2. During the rotation of the shovel 2, the dug soil matrix can be scattered to a distant place away from the pit, thereby avoiding the problem of the soil matrix quickly detaching from both sides of the shovel 2 during the rotation of the shovel 2, that is, backfilling, and ensuring the depth of the pit.

[0024] After the excavated soil matrix is ​​thrown out, there is still the problem of burying it in other nests, such as Figure 5 Therefore, to solve this problem, Figure 6-7 As shown, a convex portion 2b opposite to the arc-shaped groove structure (shown as 2a in the figure) is provided near the bottom of the shovel 2, and a scattering groove 2c obliquely facing outward is formed between the two sides of the convex portion 2b and the edge of the shovel 2. The soil matrix excavated and gathered in the arc-shaped groove structure of the shovel 2 is thrown out from the scattering grooves 2c on both sides due to the obstruction of the convex portion 2b during the process of being thrown out by the shovel 2 rotating. Figure 7 The thrown soil matrix falls on both sides of the ridge, thereby avoiding the problem of filling the excavated nest and ensuring the excavation depth of the nest.

[0025] The principle of the present application is: the nest digging machine can be assembled and connected to the agricultural machinery through the provided traction rod. During the nest digging operation, the rotating cylinder 1 is supported on the ridge body by the shovel 2. As the agricultural machinery is pulled forward, the rotating cylinder 1 rolls on the ridge body through multiple shovels 2. During the process, multiple shovels 2 contact the ridge body alternately in sequence to support the rotating cylinder 1. At the same time, relying on the body weight of the rotating cylinder 1 and the shovel 2, the shovel 2 in contact with the ridge body is inserted to a certain depth in the ridge body, and the currently inserted shovel 2 is displaced and separated from the outside of the ridge body again as the rotating cylinder 1 moves. During the separation process, a certain amount of soil matrix in the ridge body is driven (planed) to the outside of the ridge body through the surface of the shovel 2, and thrown to the outside of the ridge body along the spreading groove 2c on the shovel 2, thereby forming a nest. With the continuous traction of the agricultural machinery, nests with consistent spacing can be continuously dug out on the ridge body by multiple shovels 2.

[0026] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
