A kind of agricultural machinery travel drive gearbox

Abstract

The present invention discloses a travel drive gearbox and housing lubrication circulation system for agricultural machinery, including two matching gearbox housings, and also including a plurality of connecting parts. After the gearbox housings are installed, the two gearbox housings are fixed by the connecting parts, and the connecting parts include a fixing plate and a locking plate respectively fixed to the two gearbox housings. The travel drive gearbox and housing lubrication circulation system for agricultural machinery provided by the present invention uses an oil inlet assembly to assemble and tighten the two housings by bolts and screws, and then connects the two housings by connecting parts. When the gearbox shakes, the buffer plate vibrates, thereby causing the buffer plate to slide outside the connecting rod, so that the locking rod is stuck in the connecting rod, the locking plate and the connecting rod are locked and buffered, thereby reducing the connection strength of the bolts and screws, ensuring the stable connection of the two housings, so that the bolts and screws will not loosen, and improving the stability of the gearbox housing connection.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery accessories, and in particular to a travel drive gearbox for an agricultural machinery. Background Art

[0002] Grain combine harvesters are mainly used for combined harvesting of wheat crops. They can complete cutting, threshing, separation and cleaning operations at one time in the field. When used for segmented harvesting, a grain picker is installed on the harvesting table to pick up the grain strips after drying and complete threshing, separation and cleaning operations. When additional devices (such as soybean low-cutting devices, etc.) are added to the grain combine harvester, or after appropriate modification and adjustment, grain crops such as rice, corn, soybeans, millet and sorghum can be harvested. The combine harvester needs to be driven by an engine, which is connected to the drive shaft through a gearbox.

[0003] The gearbox needs to use lubricating oil to lubricate the engine and the drive shaft to reduce friction. The lubricating oil in the gearbox is extracted through the circulation system, and the impurities and particulate matter in it are removed through the filter. The filtered lubricating oil is dissipated by the cooling system and then re-injected into the gearbox, forming a continuous circulation process. The cooling system can effectively reduce the temperature of the gearbox oil, prevent performance degradation and failure caused by excessive oil temperature, and ensure the stable operation of the gearbox under high load and high temperature environment.

[0004] The gearbox housing and internal components are generally fastened with bolts and screws, but the gearbox will vibrate when working. Long-term vibration of the gearbox can easily cause damage to the internal components of the gearbox, and can also easily cause the fastening bolts and screws to loosen and twist, which can easily lead to loose gearbox housing and unstable connection, increasing safety hazards in the use of the gearbox. Summary of the invention

[0005] The purpose of the present invention is to provide a travel drive gearbox for agricultural machinery to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a travel drive gearbox for agricultural machinery, comprising two matching gearbox housings, and also comprising a plurality of connecting parts. After the gearbox housings are installed, the two gearbox housings are fixed by connecting parts, and the connecting parts include a fixing plate and a locking plate respectively fixed on the two gearbox housings, and a connecting rod slidably connected to the locking plate is fixedly connected to the fixing plate.

[0007] As a further description of the above technical solution:

[0008] The connecting member further comprises a sliding tube slidably arranged in the locking plate, the end of the sliding tube is fixedly connected with a buffer plate adapted to the connecting rod, a locking rod is slidably arranged in the sliding tube, the locking rod penetrates the buffer plate and extends into the connecting rod, a tension spring is arranged on the outer sleeve of the sliding tube, and the two ends of the tension spring are respectively fixedly connected to the buffer plate and the connecting rod;

[0009] It also includes a plurality of connecting rods, wherein two adjacent connecting rods are rotatably connected, and two ends of the connecting rods are rotatably connected to the sliding tube and the locking rod respectively, and a guide groove adapted to the connecting rod is provided in the locking plate.

[0010] In the above technical solution, the agricultural machinery travel drive gearbox provided by the present invention has the following beneficial effects:

[0011] The present invention: two shells are assembled and fastened by bolts and screws, and then the two shells are connected by a connecting piece. When the gearbox shakes, the buffer plate vibrates, thereby causing the buffer plate to slide outside the connecting rod, so that the locking rod is stuck in the connecting rod, the locking plate and the connecting rod are locked and buffered and shock-absorbing, thereby reducing the connection strength of the bolts and screws, ensuring the stable connection of the two shells, preventing the bolts and screws from loosening, improving the stability of the gearbox housing connection, and increasing the safety performance of the gearbox.
