Description

Tree mover with cutter capable of performing spherical motion around tree root

Technical Field

The utility model belongs to the technical field of forestry machinery, concretely relates to cutter can make spherical motion's tree mover around the root.

Background

The tree transplanting machine has two existing tree digging methods, one is a large-scale tree digging machine which is large in size, heavy in weight and high in price, is inconvenient to use and high in cost although having higher efficiency, and is often limited by an operation field; the other method is to adopt manual tree digging, the adopted tools are of two types, one type is a simple digging tool without power, the digging tool completely depends on physical power, the labor intensity is very high, the efficiency is very low, the other type is a digging machine with small power, the whole tree digging process needs to be held by the physical power, the physical power consumption is large, the efficiency is not very high, soil balls of the tree root dug are irregular, the survival rate of tree transplanting is influenced, and certain danger exists. Along with the continuous improvement of living conditions of people, the labor cost is higher and higher at present, and the tree digging device which is simple in structure, light in weight, convenient to use, regular in tree root soil ball digging, high in efficiency and safe in operation is invented, and is particularly important.

Disclosure of Invention

The utility model provides a cutter can make spherical motion's tree mover around the root, and the technical scheme who adopts is: mainly include the fixed bolster, drive arrangement, arc sword and support ring, the support ring comprises two semicircle rings, can the suit at trunk root, the axle journal is taken at the both ends of one of them semicircle ring, the fixed bolster is by the swing arm, bottom plate and axle sleeve are fixed to be formed, drive arrangement comprises power supply and transmission shaft, drive arrangement installs on the bottom plate, the transmission shaft is installed in the axle sleeve, the arc sword is fixed on the transmission shaft, the fixed bolster swing is connected on the both sides axle journal on the support ring, the axis of axle journal is in horizontal position, when the support ring suit is at trunk root, the fixed bolster, drive arrangement and arc sword are as a whole, not only can be together for the support ring luffing motion in the vertical plane, can also make circular motion around the trunk.

The beneficial effect of this technique is: the arc cutter with power drive passes through the swing arm and swings in the vertical plane around horizontal axis, do horizontal rotation around the trunk simultaneously, it is exactly a sphere to dig the orbit that the cutter passed through of tree, and curved cutter when the angle takes place great change, still can guarantee to carry out effectual cutting to earth and root, operating personnel is rotatory around the trunk on one side, do the luffing motion on one side, just can accomplish the excavation to root earth ball the overwhelming majority, remain a small part in the bottom at last, just can dig with the help of simple cutter and cut away.

The technology has the characteristics of simple structure, small volume, light weight, light operation, high operating efficiency and regular tree root soil ball shape.

In the figure: 1. the device comprises a base plate, 2, a swing arm, 3, a shaft sleeve, 4, a power source, 5, an arc-shaped cutter, 6, a support ring, 7, a handle, 8, a transmission shaft, 9, a needle bearing, 10, a center sleeve, 11, an arc-shaped cutter arm, 12, cutter teeth, 13, a fixed half ring, 14 and a movable half ring.

Detailed Description

As shown in the attached drawings, the tree mover is an embodiment of a tree mover with a cutter capable of performing spherical motion around a tree root, and mainly comprises a fixed support, a driving device, an arc-shaped cutter 5 and a support ring 6. The fixed bolster is formed by bottom plate 1, swing arm 2 and axle sleeve 3 are fixed, makes the broken line form between the upper segment of axle sleeve and the hypomere, and the hypomere is compared in the upper segment and towards the one side slope of keeping away from the swing arm, can increase the swing angle of fixed bolster like this, makes the tree mover dig more deeply. The two swing arms are fixed with the bottom plate in parallel, and the swing arms and the shaft sleeve form a herringbone shape, so that when the tail end of the shaft sleeve penetrates into the ground, the swing arms are still above the ground. The driving device consists of a power source 4 and a transmission shaft 8, wherein a motor is used as the power source, a shell of the motor is fixed on a bottom plate, handles 7 are fixed on two sides of the shell of the motor, an output shaft of the motor is connected with the transmission shaft, and the transmission shaft is arranged in a shaft sleeve. The arc sword is fixed at the end of transmission shaft, the arc sword comprises central cover 10, arc tool arm 11 and sword tooth 12, the central cover is the short pipe of section, two arc tool arms use the axis of central cover to fix the both sides at the central cover as the symmetry axis, two arc tool arms and central cover axis are in a plane together, two arc tool arms form an approximate ring, the sword tooth welding of arc sword is in the outside of arc tool arm, the blade of sword tooth is towards rotatory direction, the sword tooth of every arc tool arm is along the equidistant interval arrangement of the axis direction of central cover, the sword tooth on two arc tool arms staggers each other in the axial, can guarantee like this that the arc sword is rotatory, at the no dead angle cutting in whole sword wide region. The support ring comprises fixed semi-ring 13 and activity semi-ring 14, two semi-rings are the semicircle that the metal strip is bent into, one end adopts the pivot connection, can the rotation each other, the other end passes through bolted connection, the hole of cover bolt on the activity semi-ring is the slotted hole, connect the back of the bolt, there is certain elasticity between two semi-rings, even the trunk is out of round, also can clip and can rotate around the tree, be equipped with the axle journal in the both sides of fixed semi-ring, the fixed bolster passes through the swing arm swing and connects on the axle journal of both sides.

Introduce below the utility model discloses a use method, fix the support ring in the position that the trunk is close ground, open the motor, operating personnel holds the handle with both hands, press the arc sword to ground, rotatory arc sword begins to cut earth and root, the adjustment is dug the swing angle of tree mover and is walked around the trunk rotatory, can make the arc sword cut more and more deeply, when digging and cutting to the degree of depth like figure 6, the axle sleeve will contact ground, can adopt simple instrument to take off a bit earth at this moment, make the cutter dig more deeply, the last remaining is very little partly, as long as adopt simple cutter to assist to excavate, just can accomplish.
