Abstract

The utility model relates to a hand-push harvester for crops of a V-shaped cutting tool, comprising cutting tools, a cutter frame, a rice blocking rail and a hand-push handle. The cutting tools are installed on the cutter frame which is v-shaped. Each of the cutting tools has a field angle of 12 DEG-20 DEG, with a length of 200-400 millimetres and a bottom which is a ski-shaped glide path. Due to the comparatively reasonable lengths, field angles and bottom shapes of the cutting edges, the utility model can be used for reap crops such as rice, wheat, etc. Of different densities in the fields of different earthiness, and can reap the crops with hard stalks, such as maize, soybeans, etc. The utility model has the advantages of reaping cleanness, labor saving and damage-proof cutting tools.

Description

Manual harvester for crops

Hand push crops harvester relates to the results hand-cutting implement.Present widely used hand-cutting implement is a reaping hook, though consumption is quite big, is replaced by harvester gradually.Existing harvester is because the angle of the size of cutter and installation is unreasonable, make operation require great effort, and there is leakage to cut phenomenon, outstanding sense inconvenience is used in dense bumper harvest field, crops, and a lot of harvester cutter direct friction ground, causing the cutter rapid wear, application number is the problem that cutter and ground distance have been considered in 89217306.8 patent application, solve with adjustable height, dislike complicated in the manufacturing slightly.

Task of the present utility model provides that a kind of to cut standing grain laborsaving, and is clean, efficient is high, and cutter is difficult for abrasion, and is simple in structure, the harvester that cost is low.

The utility model is taked following structure for this reason: harvester is by there being land tool 1, knife rest 2, and hand-pushing handle 3 and shelves standing grain hurdle 4 constitute, and hand-pushing handle is the long handle with cross-peen, and a shelves standing grain hurdle is the arch steel that is welded on the knife rest.To the main improvement of prior art be knife rest by sledge shape glide path 5, V-arrangement cutter holder 6 and tubular sleeve 7 constitute; Cutlery is two serrate steel bands, and every long 200-400 millimeter is contained in the cutter holder, and the subtended angle 8 of two cutleries is 12 °～20 °

Use the utility model is harvested crops, because of its cutlery length, subtended angle and profile of tooth are constructed rationally, the every straw that feasible quilt cuts is stressed to be concentrated, and the cutter of answering that full line (ridge) crops acts on the cutlery disperses, so it is laborsaving and easily cut clean, not only can cut dense rice wheat, also can cut corn, soybean and so on the crop of thick bar, sledge shape glide path under the knife rest, make cutlery not in contact with the ground, guaranteed that harvester advances smoothly, cutlery is not fragile, is suitable for harvesting different densities and different types of crops on the field of different soil properties.

Description of drawings: Fig. 1 is a front view of the present utility model; Fig. 2 is its vertical view; Fig. 3 is the oblique ripple shape cutlery figure of most preferred embodiment 1; Fig. 4 cutlery is the detail structure of tooth; Fig. 5 is the front view of the anti-trapping board of embodiment 1; Fig. 6 is its vertical view; Fig. 7 is the harvester in parallel of embodiment 2.

Most preferred embodiment 1: glide path is made by the garden steel, and the two ends of reinforcing bar curve sledge shape, and the middle part embowment makes two ends become the left and right sides of sled; Arc middle part weldering tubular sleeve hilt, the cutter holder is made with two band steels, two ends are welded in the middle part and the end of glide path (reinforcing bar) respectively, article two, the angle of cutter holder be 13 ° 10 ', the screw that cutlery is installed is arranged above, cutlery is the steel band of 300 millimeters of two length that are pressed with oblique ripple, and the toothing of rubbing is cut sword, 60 ° of the angles of ripple and sword limit (baseline) (40 °-85 ° all can be used); The back of cutlery has elongated hole, so that be pressed in the cutter holder with nut, can adjust front and back in the cutter holder according to the abrasion situation.The zigzag sword that rubs out on this cutlery can rub stone (or emery wheel) on the plane for the ease of in undue moist soft field operation, has two anti-trapping boards 9.Can be installed in case of necessity the glide path reinforcing bar under.

Example 2: the not too dense soft bar crop of field, crops harvesting wheat class, in order further to raise the efficiency, the knife rest welding in parallel with two shelves standing grain hurdles oppositely are equipped with cutlery is contained on the same handle, and such harvester improves nearly one times of work efficiency.

Claims

1, hand push crops harvester has land tool, knife rest, shelves standing grain hurdle and hand-pushing handle to constitute by two, it is characterized in that two cutleries are installed in the holder of V cutter, subtended angle is 12 °-20 °, every cutlery length is 200 millimeters-400 millimeters, the knife rest bottom is a sledge shape glide path, knife rest top is the cutter holder, and the knife rest back side top has the tubular sleeve.
