Abstract

The utility model relates to a novel spade. The utility model belongs to the technical field of the subgroup of spades; shovels under the group of hand tools of the subclass of agricultural or forestry land preparation; components, parts or accessories of common agricultural machinery or farm implement under the class of agriculture; forestry; animal husbandry; hunting; trapping; fishing of the subsection of agriculture in the section of human necessities according to the International Patent Classification. The aim of the utility model is to solve the technical problems of convenient carrying and labour saving. The utility model is mainly composed of a rod, a wheel, a rotary rod, a clamping piece, a shaft and a spade head. The utility model is characterized in that both end positions of the shaft are embedded and arranged in positions at the inside of the rod; both end positions of the clamping piece are embedded and arranged in positions at the inside of the rod; the shaft at the side position of the wheel is arranged at a position at the top part of the rotary rod. The utility model is suitable for a practical new technical proposal in the technical field of the subgroup of spades; shovels under the group of hand tools; the utility model has the advantages of easy production, low cost and convenient operation.

Description

Novel spade

(1) technical field:

The utility model relates to novel spade, divides by International Patent Classification (IPC) (IPC) to belong to human life need part, agriculture branch, agricultural; Forestry; Livestock breeding; Hunt; Trapping; Fish big class, the whole ground of agricultural or forestry; Parts, part or the annex group of general agricultural machinery or farm implements, big group of hand-operated tools, spade; Shovel little technical group field.

(2) background technology:

At present, existing and once had about big group of hand-operated tools, spade; The technology of shovel group was all done very fruitful effort to the demand of novel spade, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Shi Zhenqing, Granted publication is CN1117340A, China Patent No. (ZL) is: No. 94118690.3 utility model patent title is the utility model patent of " a kind of collapsible spade ", the technical scheme that is adopted.At big group of hand-operated tools, spade; The technical elements of shovel group is a routine of great value invention, and it has solved the technical problem that spade can fold effectively.But still have some deficits, it also is difficult to solve easy to carry; The labour-saving technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel spade.Easy to carry to solve; The labour-saving technical problem.

The novel spade that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: bar, wheel, bull stick, intermediate plate, axle, spade head constitute.Its major part bull stick, spade head are selected for use by market.Its bar is the straight-bar shape, is material with timber, through the planing operation manufacturing.Its wheel is a toroidal, is material with plastics, through the thermoplastic processing and manufacturing.Its axle is a toroidal, is material with the steel, through the casting processing manufacturing.

In shape, structure and combination thereof, the total essential features of novel spade of the present utility model and immediate prior art is: the upper position screw thread of spade head is installed in the position of the bottom of bar, be combined into the syndeton of spade shape, function has been the effect of power transmission.In shape, structure and combination thereof, the novel spade of the present utility model technical characterictic different with immediate prior art is: the end positions of axle embeds the position of the inside that is installed in bar, the end positions of intermediate plate embeds the position of the inside that is installed in bar, be combined into the rectangular shape composite construction, function has been fixing rotary action.The lateral location axle of wheel is installed in the position at the top of bull stick, is combined into round-shaped composite construction, and function has been the effect of supporting.The solution that has so just realized novel spade of the present utility model is easy to carry; The purpose of labour-saving technical problem.

The beneficial effect of the novel spade of utility model is that the utility model is that solution is easy to carry; The technical scheme that the labour-saving technical problem is adopted and existing and once had about big group of hand-operated tools, spade; The technology of shovel group has been compared two place's advantage and improvement:

First, because the end positions that has designed axle in the technical scheme of novel spade of the present utility model embeds the position of the inside that is installed in bar, the end positions of intermediate plate embeds the position of the inside that is installed in bar, be combined into the rectangular shape composite construction, so the fixing technical problem of rotating of easier solution.

The second, owing to designed the position that the lateral location axle of wheel is installed in the top of bull stick in the technical scheme of novel spade of the present utility model, be combined into round-shaped composite construction, so the technical problem that easier solution is supported.

Fig. 2: the cross-sectional view that is novel spade of the present utility model:

The label declaration of parts in the schematic diagram:

1 bar 2 is taken turns 56 spade heads of 3 bull sticks, 4 intermediate plates

(5) embodiment:

Below in conjunction with accompanying drawing, easy to carry for realizing solution to novel spade of the present utility model; The optimal way of the technical scheme that the labour-saving technical problem is taked is described further:

Its static structure: please join accompanying drawing: as shown in the figure, novel spade of the present utility model mainly is made of bar 1, wheel 2, bull stick 3, intermediate plate 4, axle 5, spade head 6.Its major part bull stick 3, spade head 6 are selected for use by market.Its bar 1 is the straight-bar shape, is material with timber, through the planing operation manufacturing.Its wheel 2 is toroidals, is material with plastics, through the thermoplastic processing and manufacturing.Its axle 5 is toroidals, is material with the steel, through the casting processing manufacturing.

In shape, structure and combination thereof, the total essential features of novel spade of the present utility model and immediate prior art is: the upper position screw thread of spade head 6 is installed in the position of the bottom of bar 1, be combined into the syndeton of spade shape, function has been the effect of power transmission.In shape, structure and combination thereof, the novel spade of the present utility model technical characterictic different with immediate prior art is: the end positions of axle 5 embeds the position of the inside that is installed in bar 1, the end positions of intermediate plate 4 embeds the position of the inside that is installed in bar 1, be combined into the rectangular shape composite construction, function has been fixing rotary action.The lateral location axle 5 of wheel 2 is installed in the position at the top of bull stick 3, is combined into round-shaped composite construction, and function has been the effect of supporting.

Below by using method, further set forth the dynamic structure relation of this practical novel spade: in use, when needs use, according to theory of mechanics, at first bull stick 3 is put down, be put into the bottom then, use then again, thereby finish the task of support labor-saving.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of spade factory, amount is produced by batch in taking, and with the demand of supply agricultural community, so just can realize the practical value and the economic worth of novel spade of the present utility model better.
