Description

Seedling lifting shovel for south medicine seedlings

Technical Field

The disclosure relates to the technical field of agricultural machinery, in particular to a seedling lifting shovel for south medicine seedlings.

Background

The south medicinal seedling mainly comprises bare root seedlings of roughhaired holly, trigeminal bitter, radix zanthoxyli, climbing groundsel herb and the like. The south medicines are planted in Guangdong, guangxi, fujian, jiangxi and other provinces, and are popularized and planted for over ten thousand seedlings each year, and the area of seedling breeding bases reaches thousands of mu. In spring time before and after Qingming every year, all seedlings of south medicine seedlings (bare root seedlings) in seedling propagation and raising bases need to be raised, and then transplanted into a field for industrialized planting.

In field seedling raising of south medicine seedlings, ridging seedling raising is usually carried out in a standardized manner, the ridge surface width is 1.0m, the furrow width is 0.35m, the ridge height is 0.3m, south medicine seedling seeds are sowed in a fully-mechanized strip sowing mode, the row spacing is generally 15-20cm, after seedling raising is finished, a traditional manual seedling raising mode is usually adopted, an operator is required to dig seedlings through a hoe or a spade in manual seedling raising, and the seedling raising mode is low in efficiency, labor-consuming and high in cost. If seedlings are raised in rainy days, soil is more viscous, and the cost of manual seedling raising is higher.

The root of the seedling needs to be dug deeply by using a tool when the artificial seedling is used, if the experience and the strength of an operator are insufficient, the main root of the seedling is dug easily, and the survival rate of the planted seedling is low. The root soil of the dug seedling needs to be shaken off, so that soil loss in the seedling raising base is avoided, and the soil is shaken off, so that operators are required to shake the soil manually, and more time and labor cost are required. In spring time, the rainwater weather is more, and if seedlings cannot be in time out of the nursery, the industrialized planting of the south medicinal seedlings can be affected.

Patent document CN210694899U discloses a plant seedling lifting device comprising: the mounting plate, the main cutting plate, the side cutting plates and the fixed connecting piece can be used for rapidly taking out plants cultivated in a field, so that the method is convenient and rapid, and labor is saved; the seedling lifting device is small in size and light in weight, and can be used after being arranged on one side of a bucket of a forklift.

Patent document CN115918490a discloses a holly nursery assembly comprising: mounting bracket, work subassembly and drive assembly. Wherein, the external power machine of mounting bracket, work assembly installs the one end that is close to ground at the mounting bracket, and drive assembly installs on the installation, and the one end rotatable of connecting rod spare is installed on the output of rotation drive spare, and the rotatable connection screening piece of the other end of connecting rod spare, can pass through screening piece shake sieve post seedling root's earth after the piece shovel post seedling.

However, the present inventors have realized that the technical solutions disclosed in the above two patent documents are moved in parallel along the horizontal plane by external mechanical power, so that the depth of the seedling lifting shovel and the depth of the seedling are difficult to be kept consistent, and the seedling root is easily cut off, which affects the survival rate of the industrialized planting of the seedling.

Detailed Description

The seedling lifting shovel for south medical seedlings disclosed by the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the present utility model will become more fully apparent from the following detailed description and appended claims. It is noted that the drawings are in a very simplified form and use non-precise ratios for convenience and clarity in assisting in illustrating embodiments of the utility model.

Referring to the drawings, fig. 1 and 2 show perspective and side views, respectively, of a seedling lifting shovel for south medical seedlings according to the present disclosure. The shovel includes an interface assembly 1, the interface assembly 1 being for connecting (e.g., mounting) the shovel to a power machine (e.g., an excavator, particularly a stick of the excavator) to be driven by the power machine. The interface assembly 1 comprises a pair of ear plates 11 arranged opposite, preferably parallel, and fixedly connected to each other via a pin 12.

In the particular embodiment shown in the drawings, the ear plates 11 are fixedly connected to each other via a pair of pins 12, each ear plate 11 being provided with two central holes therein, the two ends of each pin 12 being respectively mounted in corresponding central holes of the oppositely disposed ear plates 11. Wherein the first pin 12 may be hingedly connected to a stick of the excavator, and the second pin 12 may be hingedly connected to a bucket cylinder of the excavator or a link hingedly connected to the bucket cylinder. In this manner, the excavator boom may drive the seedling raising blade to move, and the reciprocating motion of the excavator bucket cylinder may drive the seedling raising blade to rotate about the first pin 12.

The seedling spade for south drug seedlings according to the present disclosure further comprises a fork spade assembly 2 fixedly connected (e.g. welded, bolted, etc.) to the interface assembly 1, in particular fixedly connected to an ear plate 11 of the interface assembly 1.

The fork blade assembly 2 includes a blade support tube 21 and a plurality of blades 22 arranged substantially parallel to each other, one end (upper end in the direction shown in fig. 2) of the plurality of blades 22 being fixedly connected (e.g., welded, bolted, etc.) to the blade support tube 21, thereby forming a rake structure.

The blade support tube 21 may be implemented as a hollow or solid structure, may have a uniform diameter or a diameter that varies along its axial direction. The ear plate 11 is fixedly connected to the blade support tube 21 symmetrically around the midpoint of the blade support tube 21, such an arrangement of the ear plate 11 on the blade support tube 21 being such that the stresses in the ear plate 11 and the blade support tube 21 are uniform during operation.

The plurality of blades 22 may be configured to be substantially uniform or configured to have substantially the same shape but different sizes. Blade 22 is arcuate in shape from a side view and has a radius of curvature of 130-180cm, preferably 150cm. The radius of curvature of blade 22 as described herein refers to the radius of curvature of the inside surface 221 of blade 22.

Blade 22 has a width that decreases from the upper end to the lower end. Accordingly, the radius of curvature of the inside surface 221 of the blade 22 is greater than the radius of curvature of the outside surface 222. The progressively decreasing width of blade 22 from top to bottom results in a smaller width, and therefore a sharper lower end that is easier to insert into the soil during operation, thereby completing the seedling raising operation.

The fork and shovel assembly 2 may be configured to include any number of shovel blades, as desired. In the particular embodiment shown in the drawings, the fork and shovel assembly 2 includes six shovel blades 22.

The blade 22 according to the present disclosure is sized and configured to protect the root of the seedling from damage during the seedling raising process, increasing the survival rate of planting the seedling.

In particular, the spacing between the blades 22 is designed to be in the range of 5-15cm, preferably 10cm, depending on the root diameter of the south drug seedling. Too large a spacing between the shovels 22 can cause the entire seedling to fall from between the shovels 22, while too small a spacing can cause the soil adsorbed by the root of the seedling to be difficult to fall off.

The thickness of the blade 22 is designed to be in the range of 1-3cm, preferably 2cm, depending on the thickness of the seedling near the ground main stem and root. The thickness of the blade 22 is generally 1-3cm, so that the seedling will not be damaged transversely in the process of picking up and digging.

The length of the blade 22 is designed to be in the range of 60-90cm, preferably 75cm, depending on the qualification standard out-nursery standard of the south medical seedlings during the seedling raising process. The qualification standard of the south Chinese medicinal seedling is that the height of the overground part of the main stem is more than 40cm, and the length of the main root system of the underground department of the main stem is more than 20 cm. Considering the need to retain a certain length of the root of the seedling and the radius of curvature of the blade 22, the blade 22 has a length substantially corresponding to the sum of the aerial and underground parts of the seedling, so that the seedling lifting blade is suitable for digging out the root of the south medicine seedling and the aerial part is retained on the plane formed by the fork-blade assembly.

Further, the fork and shovel assembly 2 may further include a shovel blade connecting rod 23, the shovel blade connecting rod 23 extending through the plurality of shovel blades 22 and being fixedly connected to the plurality of shovel blades 22. Preferably, blade attachment bar 23 is disposed in a central region of the plurality of blades 22, i.e., in a region 40-60% of the blade length from the upper end of blade 22. The shovel blade connecting rod 23 can enhance the structural stability of the seedling lifting shovel, and avoids the phenomenon that the shovel blade 22 is bent or broken off from the shovel blade supporting tube 21 due to stress concentration, so that the service life is prolonged.

In use, a seedling lifting shovel for south medical seedlings according to the present disclosure, the interface assembly 1 is externally connected to a power machine, such as a stick of an excavator. The whole seedling lifting shovel is controlled by the bucket rod through the power of the excavator. And sequentially shoveling out south medicine seedlings on each ridge of seedling land blocks vertically downwards, and simultaneously digging all seedlings with roots by using the power of hooking and digging.

After the seedling is shoveled out by using the seedling shovel, the fork shovel assembly is controlled by the bucket rod of the excavator, so that the plane of the fork shovel assembly is parallel to the ground, and the seedlings are all suspended on the plane of the fork shovel assembly. And then the movable arm of the excavator generates the up-down periodic shaking force, so that the soil at the root of the south medicine seedling can be shaken off.

Through field test, compared with the process of digging seedlings by using a hoe or a spade purely manually and digging seedlings by using a bucket of a small excavator, the seedling digging shovel disclosed by the utility model can be used for completing the links of digging seedlings and shaking mud at one time, thereby saving manpower and improving efficiency, and the cost of the links of digging seedlings and shaking mud can be reduced from 1180 yuan/mu (purely manual) to 740 yuan/mu (bucket of the small excavator) to 480 yuan/mu (seedling lifting shovel disclosed by the utility model).
