Abstract
The utility model provides a combined step perforated screen for a maize harvester. The combined step perforated screen comprises a detachable step perforated screen body and a fixed step perforated screen body. The detachable step perforated screen body is installed on the fixed step perforated screen body through a bolt and then is fixed through a frame. The detachable step perforated screen body is transversely provided with at least one detachable straw shaking plate and detachable step screen pieces. The fixed step perforated screen body is transversely provided with at least one fixed straw shaking plate and fixed step screen pieces. Handles are arranged at the tail end of the frame. Maize kernel holes are formed in the detachable step perforated screen body and the fixed step perforated screen body. According to the method that the original screen pieces of a lower screen are replaced by the detachable step screen pieces, the air volume of an upper screen can be adjusted, and adaptability is improved; due to the fact that the detachable step perforated screen body is connected to the fixed step perforated screen body through the bolt, the detachable step screen pieces can be optionally installed according to practical situations, and therefore the appropriate air volume can be selected. The combined step perforated screen is simple in structure, low in cost, convenient to disassemble and assemble, practical and reliable.
Description
Technical field
the utility model belongs to reaping machine field, relates to a kind of maize harvesting machine combined type ladder stamped sieve.
Background technology
As everyone knows, cleaning room is the core component of maize harvesting machine, and the quality of its sorting performance directly affects the transaction capabilities of maize harvesting machine, and sieve plays Main Function in whole watering and separation procedure.The lower sieve structure of the corn kernel harvester that China produces is at present substantially similar, be all all-in-one-piece, some meeting of air quantity that blower fan blows to top sieve by air channel be kept off by lower Screen Out, thereby causes top sieve air quantity too small, easily make material produce and pile up, clean poor effect.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, convenient disassembly, according to the adjustable maize harvesting machine combined type of actual conditions ladder stamped sieve.
The utility model solves the technical scheme that its technical problem adopts: maize harvesting machine combined type ladder stamped sieve, comprising: detachable ladder stamped sieve, fixed step stamped sieve; Detachable ladder stamped sieve is arranged on fixed step stamped sieve by bolt, and fixes with framework; Detachable ladder stamped sieve horizontally set at least one detachably by original text plate and detachable ladder sieve; At least one is fixing by original text plate and fixed step sieve for fixed step stamped sieve horizontally set, and framework end arranges handle.
In detachable ladder sieve and fixed step sieve, be provided with corn kernel hole.
The utility model adopts the benefit good effect producing after technique scheme to be, by changing the method for detachable ladder sieve in a kind of lower sieve, realizes the adjustment of top sieve air quantity, has improved applicability; Because detachable ladder stamped sieve is connected on fixed step stamped sieve with bolt, according to actual conditions, can select to install the number of detachable ladder stamped sieve sieve, reach the object of selecting suitable air quantity, the utility model is simple in structure, with low cost, dismounting and easy for installation, practical reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model maize harvesting machine combined type ladder stamped sieve.
Fig. 2 is the operation schematic diagram of the utility model maize harvesting machine combined type ladder stamped sieve.
Embodiment
Below in conjunction with accompanying drawing, to this use is novel, be described further, as shown in Figure 1 and 2, maize harvesting machine combined type ladder stamped sieve, comprising: detachable ladder stamped sieve A, fixed step stamped sieve B; It is upper that detachable ladder stamped sieve A is arranged on fixed step stamped sieve B by bolt 6, and fixing with framework 5; Detachable ladder stamped sieve A horizontally set at least one detachably by original text plate 2 and detachable ladder sieve 1; At least one is fixing by original text plate 4 and fixed step sieve 3 for fixed step stamped sieve B horizontally set, and framework 5 ends arrange handle 7.In detachable ladder sieve 1 and fixed step sieve 3, be provided with corn kernel hole.By bolt 6, can dismantle easily or install detachable ladder stamped sieve A and fixed step stamped sieve B, the handle 7 of installation frame 5 end settings can be dismantled lower sieve F easily.
During work, the air quantity of coming from blower fan C blows to sieve F and top sieve E by air channel D, lower sieve F can be according to the number of detachable ladder sieve 1 in the detachable ladder stamped sieve of the needed air quantity adjustment of top sieve E A, make the material of its top sieve E after screening, fall into lower sieve F under normal air quantity state, lower sieve F completes last screening operation.
In practical operation, the utility model can both can combine practicality by detachable ladder stamped sieve A as the case may be together with fixed step stamped sieve B, also can cancel detachable ladder stamped sieve A, only used fixed step stamped sieve B.
The utility model is simple in structure, with low cost, dismounting and easy for installation, uses reliable.
