Description

Tree stub pruning shovel

Technical Field

The utility model relates to a shovel is pruned to trees mixed root belongs to forestry apparatus technical field.

Background

The roots of the trees are exposed to form wound packing, weeds are easy to spread and grow to the roots, the exposed packing cannot absorb nutrition in soil, and the branch wound around the roots is difficult to remove manually, so that the exposed roots need to be removed. The traditional removal method is to use the shovel to chop the shovel, and the operator needs to wave the shovel head repeatedly, and the rate of accuracy is not high, also injures other people by mistake easily, and operating efficiency is low, and intensity of labour is big moreover. The mode of sawing off by the chain saw improves the efficiency, but is inconvenient to carry, and when the thinner tree root is sawed, the ground soil or the broken stone is easy to collide, the saw blade is easy to damage, and the use cost is also very high.

SUMMERY OF THE UTILITY MODEL

In order to solve the deficiencies in the prior art, the utility model provides a shovel is pruned to trees rootlets, simple structure need not the anti-side and swings the shovel, can split the rootlet, easy operation, the degree of accuracy is high, and is also safer more laborsaving, and the suitability is wider.

The utility model provides a technical scheme that its technical problem adopted is: a tree stub pruning shovel comprises an arc shovel head, a shovel rod and an impact hammering mechanism, wherein the arc shovel head is provided with the impact hammering mechanism, the top of the impact hammering mechanism is fixedly connected with the shovel rod, after the arc shovel head shovels into a tree root, the arc shovel head is repeatedly hammered by the impact hammering mechanism to split the tree root, the impact hammering mechanism consists of a square sleeve, a supporting plate, a square pipe, an impact hammer and a limiting bolt, the back of the arc shovel head is provided with the square sleeve, the side wall of the square sleeve is fixedly connected with the square sleeve, the top surface of the square sleeve and the top surface of the arc shovel head are in the same plane, the outer side of the top of the square sleeve is fixedly connected with the supporting plate, the square pipe capable of sliding up and down is inserted into the square sleeve, the top of the square pipe above the square sleeve is fixedly connected with the impact hammer, the length of the square pipe is greater than that of the square sleeve and smaller than that of the arc shovel head, the bottom end of the shovel rod is fixedly connected with the top of the impact hammer, the side wall of the bottom of the square sleeve is provided with a pair of fixing holes, screw thread screw in has a spacing bolt on side wall of square pipe bottom portion, and the jump bit can hammer the layer board from top to bottom through the spacing of square cover and square pipe, and jump bit itself has certain weight, at the hammering in-process from top to bottom, has increased the impact force, makes the shovel head can split off the root of trees to the same of firewood. Move to the screw hole when the square pipe is coaxial with the fixed orifices on, pass the fixed orifices locking with spacing bolt and fix, whole device can regard as the fixed shovel of integral type to use, makes things convenient for the operator to carry out the excavation or fill out the soil and use.

Further, the central axis of square pipe and the axis of shovel pole in same straight line, when sliding from top to bottom, more smooth and easy more do benefit to the operation, the jump bit is the cylinder, the diameter is greater than the external diameter of square pipe, its axis is located the place ahead of square pipe and shovel pole, and central line department between the front and back cambered surface on arc shovel head cross-section, make the impact force mainly act on directly over the arc shovel head, improve the effect of chopping the root of a tree.

Furthermore, the limiting bolt can be replaced by an elastic limiting column, the elastic limiting column is composed of a flange column and a spring, round holes are formed in the side walls of the two sides of the bottom of the square tube, the flange columns extending out of the side walls of the round holes are arranged in the round holes, the spring is arranged between the flange columns, and the elastic limiting column is more convenient to replace the using mode of the trimming shovel.

The problem of pruning trees rootlets inefficiency and inconvenient carrying has been solved to this instrument, moreover, the steam generator is simple in structure, and is small, and light in weight conveniently carries more, need not the contrary side after shoveling into the rootlets and swing the shovel, avoid hindering and reaching innocent person, once fix a position the back, only need chisel about the punishment, can split the rootlets, and easy operation, the degree of accuracy is high, and is laborsaving also safer more, can regard as the instrument shovel of integral type to use simultaneously for dig the hole and fill out the soil and use, improve the suitable scene of product, satisfy forestry staff's user demand.

The beneficial effects of the utility model are that: the problem of prune trees trash root inefficiency and inconvenient carrying is solved, a trees trash root pruning shovel is provided, simple structure need not the reverse after shoveling into the root and swings the shovel, only need chisel about and hit, can split the root, easy operation, the degree of accuracy is high, and is laborsaving also safer more, can regard as the instrument shovel of integral type to use simultaneously for dig the hole and fill out soil and use, improve the suitable scene of product, satisfy forestry staff's user demand.
