Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food machinery, in particular to a grain unloading pipe gate component for a combine harvester. Background Art
[0002] A combine harvester is actually a grain harvester, which is a combined mechanical equipment for harvesting crops. It can complete the processes of harvesting, threshing, separating stems, and removing debris of cereal crops at one time, and it is a harvesting machinery that obtains grains directly from the field.
[0003] With current combine harvesters, clean grain particles are directly discharged through a discharge pipe after separation and removal of debris. Flexible curtains are mostly used at the discharge port to guide the discharged grain particles and prevent them from spilling, thereby avoiding loss of grain particles during discharge. However, the above-mentioned structure using the curtain cannot effectively control the flow rate of discharged grain particles, and cannot timely control the discharge and stop of grain particles from the discharge port. For this reason, the present application discloses a grain unloading pipe gate assembly for a combine harvester. Utility Model Content

[0005] The utility model is realized through the following technical scheme: a grain unloading pipe gate assembly for a combine harvester, comprising a grain unloading pipe of the combine harvester, a plate seat is symmetrically connected to the side wall of the port of the grain unloading pipe, one side edge of the plate seat is connected to the support plate, the lower end edge of the support plate is rotatably connected to the lower end edge of the gate plate through an axle rod, a telescopic member is obliquely arranged between the inner surface of the gate plate and the top outer wall of the grain unloading pipe, and the telescopic rod of the telescopic member passes through the top side wall of the grain unloading pipe.
[0006] As a further improvement of the above scheme, the lower end edge of the support plate is connected to pipe rod one, and slots are arranged on pipe rod one and the lower end edge of the support plate. Pipe rod two is arranged in the slot, and pipe rod two is connected to the lower end edge of the gate plate. Pipe rod one and pipe rod two are rotatably connected by an axial rod, and the grain particles fall out from the gap during the opening and closing process of the gate plate controlled by the above structure.
[0007] As a further improvement to the above scheme, the outer wall of the second pipe rod is covered with a connecting baffle, and one side of the baffle is arranged in the groove when the gate is in the open state, so as to limit the position of the gate after the gate is in the open state to reduce the load of the telescopic part when the gate is in the open state.
[0008] As a further improvement to the above scheme, the outer surface of the gate plate is symmetrically provided with stays, the lower ends of which are connected to the baffles to strengthen the strength of the gate plate and prevent the gate plate from being deformed due to excessive load. The stays increase the load-bearing capacity of the gate plate in the open state.
[0009] As a further improvement to the above scheme, guide baffles are symmetrically arranged on both sides of the gate plate to guide the grain particles discharged from the grain unloading pipe to prevent the grain particles from flowing out from both sides of the gate plate and falling, which is beneficial to the collection and bagging operations of the grain particles.
[0010] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, the opening and closing of the gate plate can be effectively controlled by the telescopic part, so as to discharge the grain particles in the grain unloading pipe, and at the same time, the opening and closing size of the gate plate and the port of the grain unloading pipe can be controlled by the telescopic part to control the speed of discharging the grain particles. In addition, the groove arranged on the lower end edge of the support plate can play a role in ensuring that the opening and closing angle of the gate plate is not too large through the blocking of the blocking card.
