Abstract

The shovel is made from plastics instead of wood material. It is easy for processing and low in cost. It can prevent from deformation and cracking. A handle sleeve can be added to facilitate mounting of the handle, and the shovel is designed with an upward angled edge to prevent the stuff from being brimmed over.

Description

A kind of shovel

The present invention relates to a kind of Farm shovel, especially substitute the plastics shovel of wooden winnowing spade.

Wooden winnowing spade is very big at the rural area consumption, is mainly used to receive beat and heap is dried grain in the sun.Because wooden winnowing spade has light weight and do not shovel ground, thus be spade can't replace.But for a long time, wooden winnowing spade also has many shortcomings:

1, the difficulty of selecting materials, difficult processing, qualification rate is low, and the cost height that causes therefrom.Because wooden winnowing spade will form with the first-class big region of runoff wood saw system of monoblock, certain radian is arranged again, so materials are very big.A timber can reach the materials width, has only those several the plates in center.And in these plates, just as meet can not using of phenomenons such as scar joint, crack, distortion.From wooden winnowing spade in shape, it is a front-thin-rear-thick, and is front wide and rear narrow.The front portion is square, and the rear portion is circular, and the front portion goes to the bottom and also an inclined-plane need be arranged, and makes it and ground that one bigger contact-making surface be arranged, and just can reach and use the smooth native requirement of not shoveling; The vertical section of whole shovel body also must be an arc simultaneously, promptly has and sticks up.And these requirements entirely by artificial saw, plane, file, are stuck up inadequately to some, also will bake to press and finish, and the difficulty of its processing is well imagined.Main is, owing to be subjected to processing (mainly finger can not form suitability for industrialized production) particularly influence of timber quality, makes " qualification rate " (also do not have certain standard at present, refer to be satisfied with) of wooden winnowing spade very low.And these have finally caused increasing of cost.In recent years, along with the minimizing of big footpath willow, the price of wooden winnowing spade rises steadily, and every is generally more than 5 yuan, and is continuing rise.

2, wooden winnowing spade is the same with other timber, meets rainwater and is exposed to the sun, and distortion, phenomenon such as crooked and dry and cracked can occur.Especially wooden winnowing spade is thinner, the more obvious and easy generation of this phenomenon.But as the maximum wooden winnowing spade of open-air use in summer, wet by the rain and burnt by the sun being difficult to avoided.The generation of this phenomenon then makes this with regard to few qualified products, becomes substandard products or unrenewable.

3, wooden winnowing spade is thinner, runs into collision, usually falls down and scraps along the texture monoblock of timber.This damage accounts for 40% of total damage.These shortcomings of wooden winnowing spade cause it the strange phenomenon of " do not damage, but damage " to occur, have brought very big burden to the user.

4, kind is single, unreasonable structure.Because be subjected to the restriction of material, for a long time, wooden winnowing spade has only " Wood shovel board for throwing material type ", and this is a kind of.This shovel type biggest advantage is to use light and flexible, but also has two shortcomings (1), this shovel will be with special handle, and valency is higher, about every 4.5 yuan.(2) because its approximate plate, shovel the finite volume of thing at every turn, if when lighter thing of shovel such as chaff, fringe and so on, then operating efficiency is very low.Therefore, this single kind can not satisfy different needs.

In short supply based on willow, a lot of in recent years people attempt to make wooden winnowing spade with other timber, but all undesirable and be eliminated.This is also understandable, and willow collection weight is suitable, has in gentle toughly, and other timber is difficult for replacement really.Before and after 87 years, there is the people to manufacture wooden winnowing spade with plywood again,, has two shortcomings to be difficult for overcoming though its cost is lower: the one, the thickness problem.The shovel that plywood is made, each several part are equally thick, have approached to hold to can't stand weight, thick use too stupid; The more important thing is that after this shovel jagsaw formed, four limits were burr, very easily aliquation is not durable very much, and this shovel do not have and stick up, and uses smoothly shovel ground easily yet.So it is only short-lived on market just to disappear again.

These shortcomings of wooden winnowing spade can not overcome for a long time, and its basic reason is that people have such prejudice: " wooden winnowing spade " (general reference has the shovel of wooden winnowing spade function) has only with timber and makes.This prejudice makes " wooden winnowing spade " this difficult problem can not get for a long time solving, and has seriously hindered the development of this product.

Purpose of the present invention overcomes many shortcomings that present wooden winnowing spade exists exactly, and specifically, it is wide just to provide a kind of raw material, easily processing, and cost is low, and the high-quality shovel of anti-use increases kind simultaneously, to satisfy different needs.

Above-mentioned purpose is achieved in that with plastics and replaces timber, makes shovel with one-shot forming technique again, just substitutes wooden winnowing spade with the plastics shovel.The shape of plastics shovel has two kinds: 1, band cover type.Fig. 1 is its structural representation.Its feature is the cover that adds that on traditional Wood shovel board for throwing material type the peace handle is used.Because the different angle of sleeve, can regulate shovel and stick up, so the radian of this shovel can be done smallerly, even the front portion of shovel do not have radian, uses with convenient.2, traditional " Wood shovel board for throwing material type ", Fig. 2 is its shape schematic diagram.This shovel type, though peace handle expense height, it has its advantage, after it was used instead plastics and makes, the many shortcomings before having overcome were that market potential is arranged very much, thus should keep, to satisfy different needs.

For shovel shovel thing is not leaked down, can be with the both sides of above-mentioned two kinds of shovel type shovels, or comprise and the limit at rear portion upwards turning up, make shovel formation concave surface, be called the flanging type.Fig. 3 is the cross section of flanging type shovel.

The plastics shovel is compared with wooden winnowing spade and is had the following advantages:

1, raw material is wide, and easily processing particularly owing to adopt suitability for industrialized production, can be boosted productivity greatly and product percent of pass, thereby the cost of shovel is reduced greatly, and every only needs about monobasic.Simultaneously can no longer be subjected to the restriction of material, and can do various useful improvement to shovel as required.This helps constantly improving and development of this product.

2, the plastics shovel not can because of wet by the rain and burnt by the sunly deform, phenomenon such as drying, thereby can increase the service life.

3, the plastics shovel does not have the such texture of wooden winnowing spade, is not easy the piece phenomenon.

4, the flanging type of plastics shovel increase can prevent from down to leak and increase work efficiency, and can meet the different needs.The band cover type that increases then can reduce the expense of handle, and the handle valency is reduced to more than 1 yuan by 4 yuan.Like this, the cost of a shovel is reduced to 2.5 yuan by 10 yuan of original wooden shovel, and it is durable to add the plastics shovel, and several usefulness of Yi Zhangding are so its benefit is tangible.

Claims

1, a kind of shovel is shaped as traditional Wood shovel board for throwing material type, and it is characterized in that: this shovel is made of plastic.

2, according to claim 1 described shovel, it is characterized in that: it be shaped as " band cover type ", it is to be formed by the cover that adds the peace handle on the shovel of Wood shovel board for throwing material type.

3, according to claim 1 or 2 described shovels, it is characterized in that: this shovel both sides or comprise that the limit at rear portion upwards turns up.
