Description

One kind cutting plastic limit soil item knife

Technical field

The utility model is related to ground plastic limits to measure experimental technique field, and in particular to one kind cutting plastic limit soil item knife.

Background technology

The purpose that plastic limit measures experiment is to measure the plastic limit of soil, determines the classification of soil, so as to according to native under natural conditions Moisture content determine which type of state soil under natural conditions is in, improve application parameter for engineer application.

Plastic limit refers to the limit moisture content (Wp) when soil is transitioned into semi-solid state by plastic state.Plasticity boundary Wp= (Gp/Gs) X 100%, Gp are the quality of contained humidity when becoming semisolid from plastic state；Gs is absolutely dry clay quality.Mesh Preceding to need to cut to measuring soil when carrying out plastic limit measurement but current cuts the universal common pocket knife of native cutter, The requirement for once cutting multiple native items is cannot be satisfied, needs to be cut for multiple times, causes the time to waste, and the ground soil item cut out can not Ensure identical width, cannot be satisfied measurement and require.

Utility model content

The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of easy to use cut Plastic limit soil item knife.

Technical solution is used by realize the purpose of this utility model：

One kind cutting plastic limit soil item knife, includes the blade of multiple spaced and parallel settings, and the distance between the blade is identical, The blade is fixed on knife rest plate, and the width direction both sides of the knife rest plate are respectively equipped with fixed plate, pacify in the fixed plate Equipped with handle, the surface of the knife rest plate is formed with multiple stomatas.

Native item is formed between each two blade cuts out space, and each described cut out has the gas above space Hole.

Being cut out described in each has the stomata above space be three.

The utility model cuts plastic limit soil item knife, and native knife is cut relative to traditional, and operation saves time, and is especially convenient for every All reach code requirement, due to there are multiple blades, the spacing between blade and blade is identical, and multiple soil items are once cut into, and every The width of a soil item is almost the same, realizes uniform.

Description of the drawings

Fig. 1 is the overall structure diagram for cutting plastic limit soil item knife；

Fig. 2 is the schematic top plan view for cutting plastic limit soil item knife；

Fig. 3 is the elevational schematic view for cutting plastic limit soil item knife.

Specific implementation mode

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.

Referring to shown in Fig. 1-3, one kind cutting plastic limit soil item knife, including：

The blade 5 of multiple spaced and parallel settings, the distance between the blade is identical, and multiple blades are fixed on knife rest On plate 1, the width direction both sides of the knife rest plate are respectively equipped with fixed plate 3, and handle 4, the knife are equipped in the fixed plate The surface of frame plate is formed with multiple stomatas 2, gas when to cut soil inside discharge.

Preferably, the length of the knife rest plate is 5cm, is highly 3cm, width 3cm, and the handle is cylindrical hand Handle, length 3cm, a diameter of 1.5cm, the distance between blade is 0.5cm.

The height of the blade is 3cm, and the height of the fixed plate is less than the height of blade, be blade height half or It is one third.

The knife rest plate is that steel plate makes to be formed, and is welded and fixed with the fixed plate of same material, the fixed plate and hand Handle welds and steel material is used to make.

The bottom of blade inner surface corresponding with knife rest plate is welded and fixed, and is welded with the inner surface of the fixed plate Connect fixation.

The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change The scope of protection of the utility model is also should be regarded as into retouching.

Claims

1. one kind cutting plastic limit soil item knife, which is characterized in that include the blade of multiple spaced and parallel settings, between the blade Apart from identical, the blade is fixed on knife rest plate, and the width direction both sides of the knife rest plate are respectively equipped with fixed plate, described solid Handle is installed, the surface of the knife rest plate is formed with multiple stomatas on fixed board.

2. cutting plastic limit soil item knife as described in claim 1, which is characterized in that one native item of formation cuts between each two blade Go out space, each described cut out has the stomata above space.

3. cutting plastic limit soil item knife as claimed in claim 2, which is characterized in that it is each described cut out above space have it is described Stomata is three.
