Description

Technical Field

[0001] The invention relates to the technical field of digging, in particular to a seedling digging device with a root protection function. Background Art

[0002] Seedlings are tree seedlings with root systems and trunks. All seedlings cultivated in nurseries, regardless of age, are called seedlings before they are planted. There are three types of seedlings: seedlings, vegetative propagation seedlings, transplanted seedlings, and bed-retained seedlings. Seedlings can also be classified according to trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. This is mainly caused by the growth climate.

[0003] Seedling digging equipment is an indispensable tool in landscaping, forestry production and agricultural planting. They are mainly used for digging, transplanting and transporting seedlings. According to their different digging methods, they are also divided into handheld seedling diggers, tree diggers with soil balls, 360° rotating tree diggers, three-shovel hydraulic tree diggers and circular knife tree diggers, etc., and these equipment that can be used to dig seedlings can all be called seedling digging equipment.

[0004] However, when using the circular knife tree digging machine to dig seedlings, part of the roots of the seedlings will be cut off. In the subsequent planting process, the seedlings may die due to the damaged roots. This equipment has low protection performance for the roots of seedlings and in order to prevent sticking and loosening of the soil ball on the seedlings, it is necessary to manually bundle them. The operation is relatively cumbersome, thereby delaying the delivery efficiency of the seedlings. Therefore, it does not meet the existing needs.

In the same direction, as the clamping plate 23 moves, the protective cotton 24 fixed thereto will move toward the direction of the elm sapling 3. When the two protective cottons 24 are respectively in contact with the two sides of the outer surface of the elm sapling 3 and the clamping plate 23 can no longer be pushed, the fixed elm sapling 3 and the soil ball located on the outer surface of the root of the elm sapling 3 are moved upward by the second lifting platform 21. At this time, the soil ball located on the outer surface of the root of the elm sapling 3 is moved to a height of thirty centimeters from the ground by the second lifting platform 21.

[0036] The opening and closing mechanism includes two fixed cylinders 19, the piston rod of the fixed cylinder 19 is connected to a push sleeve 17, and a push plate 16 is provided on both sides of the push sleeve 17, and the surface of the push plate 16 facing the inner wall of the push sleeve 17 is an inclined surface 18; the two push plates 16 located on the upper side are fixed between the sealing knife 12 located on the upper side of the semi-annular excavating knife 7, and the two push plates 16 located on the lower side are fixed between the sealing knife 12 located on the lower side of the semi-annular excavating knife 7; one side of the push plate 16 is provided with a metal rod 13 fixed to the semi-annular excavating knife 7, and the outer surface of the metal rod 13 is sleeved with a push spring 15, one end of the push spring 15 is connected with a push sleeve 14 movably sleeved on the outer surface of the metal rod 13, and the surface of the push sleeve 14 facing the sealing knife 12 is fixed to the sealing knife 12; when the soil ball located on the outer surface of the root of the ash seedling 3 moves into the air, the push sleeve is pulled inward by the fixed cylinder 19 Cylinder 17, with the movement of the pushing sleeve 17 and the spring force of the pushing spring 15, the pushing sleeve 14 and the sealing knife 12 fixed thereto will move outward together, with the movement of the sealing knife 12, the spray head 11 sealed by the sealing knife 12 will be exposed to the outside world, when the spray head 11 is completely exposed to the outside world, the semi-annular excavation knife 7 is rotated again by the excavation rotating mechanism, at this time, in the process of rotating the semi-annular excavation knife 7, the rooting agent 10 located inside the metal material tube 9 is extracted by the spray head 11 and sprayed on the outer surface of the soil ball at the root of the ash seedling 3, the rooting agent 10 can stimulate the regeneration speed of the surface of the severed root system and accelerate the formation of new roots, so as to prevent external bacteria from entering the interior of the ash seedling 3 through the surface of the severed root during the subsequent sale and transplanting process, thereby improving the survival rate of the ash seedling 3, and enhancing the protective performance of the equipment on the roots of the ash seedling 3 through the above technical scheme;

[0037] When the rooting agent 10 is sprayed, the push sleeve 17 is pushed outward by the fixed cylinder 19.

[0038] The inclined digging surface 27 on the outer surface of the sealing blade 12 can prevent the sealing blade 12 from interfering with the digging work of the semi-annular digging blade 7 .

[0039] The root high protection excavation mechanism also includes two delivery pipes 25, which are respectively connected to the two ends of the metal material pipe 9; the rooting agent 10 can be added to the inside of the metal material pipe 9 through the delivery pipes 25 to ensure that the spray head 11 can operate normally.

[0040] The outer surface of the root high protection excavation mechanism is fixedly installed with a seedling root wrapping mechanism 2, which includes two first lifting rails 213, two first lifting platforms 214, two L-shaped metal hollow shells 201, two long cylinders 202, two arc-shaped pushing plates 203 and two arc-shaped root soil wrapping shells 206 to be merged.

The two arc-shaped root soil encapsulating shells 206 to be merged are respectively placed inside the two arc-shaped pushing plates 203. The outer surfaces of the arc-shaped root soil encapsulating shells 206 to be merged are provided with a plurality of air holes 208. A conical fixing head 209 is fixedly provided at the three end corners on the upper side of the inner wall of the arc-shaped root soil encapsulating shells 206 to be merged, and the top end of the conical fixing head 209 is arc-shaped.

[0041] The seedling root wrapping mechanism 2 also includes two placement grooves 204, which are respectively located on the upper end surfaces of the two L-shaped metal hollow shells 201, and the interiors of the two placement grooves 204 contain multiple arc-shaped root soil wrapping shells 207; before the equipment is installed, the arc-shaped root soil wrapping shells 207 are first added to the interiors of the two placement grooves 204.

[0042] The outer surface of the arc-shaped root soil wrapping shell 207 is provided with a plurality of air holes 208, and the three end corners on the upper side of the inner wall of the arc-shaped root soil wrapping shell 207 are fixed with a conical fixing head 209. The shape of the arc-shaped root soil wrapping shell 207 is the same as the shape of the arc-shaped root soil wrapping shell 206 to be merged, and the arc-shaped root soil wrapping shell 206 to be merged and the arc-shaped root soil wrapping shell 207 are both made of soft wood in one piece;

[0043] An L-shaped slot is provided on the lower side of the rear end surface of the arc-shaped root soil wrapping shell 206 and the arc-shaped root soil wrapping shell 207 to be merged on the left side, and an L-shaped fixing bracket is provided on the lower side of the front end surface of the arc-shaped root soil wrapping shell 206 and the arc-shaped root soil wrapping shell 207 to be merged on the right side; in the process of adding the arc-shaped root soil wrapping shell 207, it is necessary to pay attention to adding the arc-shaped root soil wrapping shell 207 with the L-shaped slot on the outer surface to the inside of the placement groove 204 on the left side, and adding the arc-shaped root soil wrapping shell 207 with the L-shaped fixing bracket on the outer surface to the inside of the placement groove 204 on the right side.

[0044] A support cylinder 210 is provided on one side of the bottom arc-shaped root soil wrapping shell 207, which is fixedly installed inside the L-shaped metal hollow shell 201. The piston rod of the support cylinder 210 is connected to a support plate 211, and the surface of the support plate 211 facing the arc-shaped root soil wrapping shell 207 is an arc-shaped support surface 212; the lower end surface of the bottom arc-shaped root soil wrapping shell 207 added to the placement groove 204 will contact the arc-shaped support surface 212 located on the outer surface of the support plate 211, and the arc-shaped root soil wrapping shell 207 can be supported by the support plate 211 to prevent it from falling into the arc-shaped pushing plate 203 without authorization. When the soil ball located on the outer surface of the root of the elm sapling 3 is sprayed with the rooting agent 10, the support plate 211 is pulled outward by the support cylinder 210. When the support plate 211 is located on the outer surface of the support plate After the arc-shaped supporting surface 212 is no longer in contact with the arc-shaped root soil covering shell 207 located at the bottom, under the action of gravity, the arc-shaped root soil covering shell 207 located at the bottom will fall into the interior of the arc-shaped pushing plate 203 and become the arc-shaped root soil covering shell 206 to be merged. It should be noted in this process that when one arc-shaped root soil covering shell 207 has completely fallen into the interior of the arc-shaped pushing plate 203 and becomes the arc-shaped root soil covering shell 206 to be merged, the supporting plate 211 is pushed inwardly by the supporting cylinder 210 to push all the arc-shaped root soil covering shells 207 located above the arc-shaped root soil covering shell 206 to be merged upward, so as to prevent the arc-shaped root soil covering shell 206 to be merged from being stuck by the arc-shaped root soil covering shell 207 and unable to be pushed outward.

[0045] An electric suction head 205 fixed to the inner wall of the arc-shaped pushing plate 203 is provided below the supporting cylinder 210, and the surface of the electric suction head 205 facing the arc-shaped root soil wrapping shell 206 to be merged is in contact with the arc-shaped root soil wrapping shell 206 to be merged; when the arc-shaped pushing plate 203 contains the arc-shaped root soil wrapping shell 206 to be merged, it is fixed by the electric suction head 205, and when the two arc-shaped root soil wrapping shells 206 to be merged are fixed, the two arc-shaped pushing plates 203 are pushed inward synchronously by the two long cylinders 202, and as the arc-shaped pushing plates 203 move, the two arc-shaped root soil wrapping shells 206 to be merged will converge on the outer surface of the root soil ball of the Manchurian ash seedling 3, and the two arc-shaped root soil wrapping shells 206 to be merged can be fixed to each other by the L-shaped card grooves and L-shaped fixing brackets respectively located on the outer surfaces of the two arc-shaped root soil wrapping shells 206 to be merged;

[0046] When the two arc-shaped root soil encapsulating shells 206 to be merged are merging inward, the conical fixing head 209 fixed on the inner wall of the arc-shaped root soil encapsulating shells 206 to be merged will also be inserted into the root soil ball of the ash seedling 3, so as to fix the arc-shaped root soil encapsulating shells 206 to be merged and the root soil ball, and prevent the arc-shaped root soil encapsulating shells 206 to be merged from falling off;

[0047] The air holes 208 located on the outer surface of the arc-shaped root soil wrapping shell 206 to be merged can prevent the arc-shaped root soil wrapping shell 206 to be merged from completely sealing the root soil ball of the ash seedling 3 from the outside world to ensure the air circulation. The seedling root wrapping mechanism 2 in the above technical solution can automatically cover the two arc-shaped root soil wrapping shells 206 to be merged directly on both sides of the outer surface of the soil ball to wrap it, so as to prevent the soil ball located outside the root of the ash seedling 3 from spreading when the ash seedling 3 is sold later, thereby increasing the functionality of the device;

[0048] Since the arc-shaped root soil wrapping shell 206 to be merged is made of an integrated soft wood, there is no need to remove the arc-shaped root soil wrapping shell 206 to be merged when planting the elm saplings 3. When planting the elm saplings 3, it is buried inside the pit. The wood of the arc-shaped root soil wrapping shell 206 to be merged is relatively soft, and it contains more cellulose and hemicellulose. These components can be degraded faster under the action of microorganisms in the soil, thereby releasing nutrients. These nutrients can further improve the survival rate of the elm saplings 3 and improve the soil structure.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
