Module combined multifunctional threshing machine

Abstract

The invention provides a module combined multifunctional threshing machine, which relates to the technical field of combined threshing machines. The module combined multifunctional threshing machine comprises a common cleaning rack, a common transmission mechanism, a common screening and impurity removing mechanism, a common spiralconveying mechanism and a common grain blow-out mechanism, and further comprises replaceable feeding and threshing modules, wherein the feeding and threshing modules are arranged aiming at similar crop characteristics; internal members in the replaceable feeding and threshing modules are connected into a whole body; each feeding and threshing module is connected with the rack through a locking device in a replaceable manner. According to the module combined multifunctional threshing machine, each feeding and threshing component which is independently arranged according to the similar crop threshing characteristic is integrated to be a specific module, meanwhile, the components such as the transmission component and the screening and impurity removing component are shared, a unit can be quickly replaced to finish threshing during threshing aiming at specific crops; each feeding and threshing module of the threshing machine is arranged aiming at similar crops, so that the threshing machine has higher pertinence; since some components are shared, the production cost is reduced; the maintenance cost and the use cost are also reduced because of the simple and compact structure; easy shift, assembly and operation can be realized.

Description

technical field [0001] The invention relates to a threshing device with a rotating working part, in particular to the technical field of a combined thresher. Background technique [0002] A thresher is a harvesting machine, mainly referring to the harvesting machine of food crops, and refers to a machine that can separate the grains of the crops from the stalks. Existing threshers have single functions, carry more sundries, cause a large loss of grain, and have a high amount of crushing, which is not conducive to the improvement of grain quality. When using them, the types of threshers selected are also different according to the different crops, such as "Rice thresher" is suitable for threshing rice; the one used for corn threshing is called "corn thresher", etc. The same thresher cannot perform threshing operations on various crops, such as rice, wheat, corn, beans, etc. Simultaneous threshing, the existing single-function thresher is powerless, and farmers must use at le...

Problems solved by technology

Existing threshers have single functions, carry more sundries, cause a large loss of grain, and have a high amount of crushing, which is not conducive to the improvement of grain quality. When using it, the types of threshers selected are also different according to the different crops, such as The "rice thresher" is suitable for threshing rice; the one used for corn threshing is called "corn thresher", etc. The same thresher cannot perform threshing operations on various crops, such as rice, wheat, corn, beans, etc. Simultaneous threshing, the existing single-function thresher is powerless, and farmers must use at least three threshers such as rice and wheat threshers, corn threshers, bean threshers, and typhoon cabinets to achieve various crop threshing and cleaning tasks. , which increases the purchase cost of the equipment, farmers must also be familiar with the operation and maintenance procedures of these equipment, which increases the difficulty, and the storage of these equipment also needs to occupy a large space

[0003] In order to make up for the single-function defects of existing threshers, some agricultural machinery manufacturing enterprises have developed related multi-functional detachment equipment.

[0004] We know that when different crops are threshing, the requirements for the overall frame of the thresher, transmission parts, screening and impurity removal parts, etc. are basically the same. Different, the requirements for the feeding part and the threshing part are quite different. The method usually adopted by the existing so-called multi-functional thresher is to make a compromise between the feeding part and the threshing part, and add some auxiliary control mechanisms at the same time. , so that it can basically complete the threshing of different crops, but in fact, for any similar crops, the structural settings of this thresher cannot fully meet its threshing requirements, that is to say, this type of multi- The functional thresher is exactly a product of compromise of various functions. It pursues an overall performance that can basically meet the requirements, but its threshing effect for similar crops is not excellent.

[0005] For example, "multifunctional thresher 02245767", which discloses a multifunctional thresher, in order to ensure that various crops such as kidney beans, soybeans, and wheat are threshed, a vertical and horizontal adjustment hydraulic cylinder and an adjustment screw are provided to A variety of variable speed methods are realized, and it has a high degree of automation. It can be seen that in order to achieve the multi-functional purpose of threshing beans and wheat, the equipment has given up the best structure and speed settings for similar crops. A variety of auxiliary components are added, which not only fails to achieve the best threshing effect, but also increases the complexity of the equipment, which also increases the manufacturing cost and maintenance cost of the equipment.

[0006] In addition, the existing threshers are not highly automated, and rely too much on human participation. For example, when the existing rice and wheat threshers work, it is necessary to manually pull the wheat handles into the machine for repeated threshing. The labor intensity of the operator is too high, and the threshing efficiency is also very low, which is not conducive to improving agricultural productivity
