Background technology
In Rice Production scientific research, often need to understand the growth and development state of rice root, so that the growth conditions of analyzing rice.Under existence conditions, scientific research personnel adopts the method that paddy rice is extracted or dug out from soil conventionally, so not only inefficiency, can not guarantee the uniformity of every sub-sampling, but also can destroy the integrality of rice root, can not obtain all root systems, particularly can not understand distribution and the form of its root system in soil.In order to solve this difficult problem, design a kind of rice root soil sampling device, in order to acquisition rice root that can be efficient, complete in the scientific research of paddy rice.
Summary of the invention
Goal of the invention of the present utility model is: by manufacturing and designing a kind of simple in structure, practical and convenient root soil sampler, solution root system sampling efficiency in rice science test is low, the unwarrantable problem of quality, significant to the normalizing operation of raising rice root sampling.
For achieving the above object, the utility model adopts following technical scheme:
A kind of rice root soil sampling apparatus, comprises square sampling frame, and described square sampling frame is the main part of rice root soil sampling apparatus, big up and small down, has certain taper; Two ends, described square sampling frame right side have and respectively have a vertical hole, in hole, are vertically shackle line.Respectively there is a tension and compression handle left and right, described rice root soil sampling apparatus top.
Slidably cutting blade is equipped with in described rice root soil sampling apparatus bottom, and described cutting blade is installed in the chute of square box bottom by two knife blocks, and described knife block is connected with power set by wire rope.Right side, described rice root soil sampling apparatus top is blade power set.
Described power set are made up of main shaft, crank and fastening devices thereof.Described main shaft two ends lay winding wire ropes, is installed on tension and compression handle by fastening devices.Described front-end of spindle is square, can be connected with the sleeve of crank front end, and described crank, for being connected with main shaft, provides main shaft rotational power.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
Rice root soil sampling apparatus of the present utility model, can be pressed in soil more easily, drives sharp blade cuts bottom soil by manpower, can greatly reduce people's labour intensity;
Rice root soil sampling apparatus of the present utility model, simple to operate, can effectively improve the sampling efficiency of rice root soil;
Rice root soil sampling apparatus of the present utility model, can guarantee that each rice root soil sample is all consistent, avoids the error causing because soil sample is inconsistent in test.
Accompanying drawing explanation
Fig. 1 is that rice root soil sampling apparatus master of the present utility model looks schematic diagram;
Fig. 2 is rice root soil sampling apparatus schematic top plan view of the present utility model;
Fig. 3 is the sectional view of rice root soil sampling apparatus chute of the present utility model.
The square sampling frame of mark in figure: 1-, 2-wire rope, 3-main shaft, 4-main axis fixing device, 5-tension and compression handle, 6-crank, the vertical hole of 7-, 8-fulcrum, 9-chute, 10-knife block, 11-cutting blade, 12-block piece.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that concrete case study on implementation described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 3, described rice root soil sampling apparatus of the present utility model, comprise square sampling frame 1, it is characterized in that: the back taper that framework is big up and small down, tapering is 1 ~ 2 °, be conducive to so whole device and be pressed in soil, be also conducive to rice root soil and take out from sampling frame simultaneously; Bottommost is inclined-plane; Blade chute 9 is arranged at sampling frame bottom; Respectively there is a tension and compression handle 5 about described square sampling frame top, square sampling frame is pressed into and takes out soil when operating.
Described rice root soil sampling apparatus, adopts the horizontal slip of blade to separate underground.Described cutting blade 11 two ends are fixed on slide block 10, and slide block 10 is installed in chute 9.Described slide block 10 is by wire rope 2 tethered slidings.Described wire rope 2 one end are connected with slide block 10, and one end is walked around fulcrum 8 and is connected with power spindle 3 through vertical hole 7.Described fulcrum 8 is can be around the guide wheel of center rotating, for changing the transmission direction of wire rope 2.Described vertical hole 7 is circular port, is the moving conduit of wire rope 2, and one end communicates with chute 9, and the other end communicates with square sampling frame 1 top.
Described rice root soil sampling apparatus, power section, on right side, top, relies on the artificial crank 6 that rotates to drive main shaft 3 to rotate.Described main shaft 3 is installed on by two place's fastening devicess 4 on the tension and compression handle 5 of square sampling frame 1 upper right side, can only carry out one-dimensional rotation; Piece 12 is blocked at described main shaft 3 two ends, drops in order to anti-locking apparatus wire rope 2 in rotation process, and one section is square foremost, for being connected with crank 6.Described crank 6 front ends are square shrinkage pool, are independent sector, do not have physical connection with rice root soil sampling apparatus, easy to carry and use.
The operating principle of described rice root soil sampling apparatus is: before use, cutting blade 11 is placed in square sampling frame 1 high order end chute, paddy rice above ground portion is placed in square sampling frame 1, tension and compression handle 5 is exerted pressure, square sampling frame 1 is pressed into soil appropriate depth, connecting crank 6 is connected with main shaft 3, the artificial crank 6 that rotates, crank 6 drives main shaft 3 to rotate, the rotation of main shaft 3 is upwards drawn wire rope 2, wire rope 2 will vertically move the transverse shifting that is converted into slide block 10 and cutting blade 11 through fulcrum 8, thereby cutting realizes the separation of subsoil, finally paddy rice entirety is taken out from square sampling frame 1, by tension and compression handle 5, square sampling frame 1 is taken out from soil again, complete primary sample work.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
