Description
Technical field
The utility model is related to harvester device technical field, and in particular to a kind of harvester grid concave plate.
Background technology
Grid concave plate is an important component for constituting harvester, and grid concave plate constitutes threshing chamber with roller, and playing will be de-
The effect that the cereal of grain is screened.Grid concave plate of the prior art includes longitudinally disposed side plate, the transverse slat laterally set
And through the steel wire of transverse slat.The grid concave plate of above-mentioned prior art is that a welding is overall, there is many passes in its welding process
Connection size is needed to ensure, due to the limitation of its composition structure, and the size that welding personnel is typically only capable to be marked according to drawing is carried out
Welding, in welding process the guarantee of size exist all the time than it is larger the problem of, cause the grid concave plate that ultimately forms up to not
To preferable screening effect, the Threshing of threshing chamber finally constituted is influenceed.In addition, grid concave plate in the prior art
Transverse slat is made up of several end floor beams, the welding unit that adjacent side plates are constituted with tail trimmer connecting the two so that grid concave plate
Integral solder point is more, causes the manufacturing procedure complexity of grid concave plate, and the structure of the grid concave plate finally constituted is also unstable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of excellent harvester of screening effect recessed with grid
Plate.
In order to solve above-mentioned problem of the prior art, the utility model is realized using following technical scheme：
The utility model harvester grid concave plate, including notch board main body, the upper end connection for being arranged at notch board main body upper end
Part and the lower end connection for being arranged at notch board main body lower end, the notch board main body include longitudinally disposed supporting plate, laterally set
The transverse slat and the steel wire through transverse slat put, the supporting plate include the inner support plate in the middle part of transverse slat and the outer branch of transverse slat end
Fagging, the external support board is provided with the position observation mouthful for transverse slat end positioning welding, and the inner support plate is provided with for horizontal
The installation otch of the installation otch that plate is vertically embedded into, the transverse slat and inner support plate is weldingly connected.
The position observation mouthful is the breach for being arranged at external support board edge.Position observation mouthful is arranged on external support board edge
So that external support board manufacturing process is simpler, locating effect is more preferable.
The depth for installing otch is not less than 1/2nd of transverse slat width.Otch is installed and causes horizontal stroke under these conditions
Plate weld is more consolidated, and the harvester of composition is higher with grid concave plate overall structure stability.
The gauge of wire is 3-5mm, and the spacing of adjacent wires is 10-18mm.What steel wire was constituted under these conditions
Harvester is excellent with grid concave plate screening effect.
The upper end connection and lower end connection are the angle steel provided with bolt hole.Using angle steel so that the utility model
Overall structure is more stablized.
The utility model is relative to the advantage of prior art, first, the utility model passes through to be set on external support board
Position observation mouth can be precisely located the welding position of transverse slat, directly transverse slat end is welded according to the position of position observation mouthful
It is connected on external support board, is effectively guaranteed the accuracy of each size so that the harvester grid concave plate ultimately formed can
Preferable screening effect is reached, the position precision of welding is improved；Second, the installation otch set in inner support plate can be for horizontal stroke
Plate is first embedded in and welded afterwards, on the one hand improves the stability of structure, on the other hand reduces harvester grid concave plate entirety
Pad, reduces technology difficulty, improves production efficiency while also effectively reducing production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged diagram of the position observation mouthful of part A in Fig. 1.
Fig. 3 is the structure enlarged diagram of the installation otch of part B in Fig. 1.
Wherein, reference is as follows：In 1- notch board main bodys, 11- transverse slats, 12- steel wires, 131- external support boards, 132-
Supporting plate, 1310- position observations mouthful, 1320- installs end connection under otch, the upper end connections of 2-, the upper end bolt holes of 21-, 3-,
31- lower end of the bolts hole.
Embodiment
The utility model harvester grid concave plate, including notch board main body 1, the upper end company for being arranged at the upper end of notch board main body 1
