Description

Technical Field

[0001] The present application relates to the technical field of threshers, and in particular to a thresher crushing component. Background Art

[0002] A thresher is a piece of agricultural machinery used to separate crop grains from their stalks. It plays a particularly important role during the harvest season, efficiently threshing grains and other crops, significantly reducing farmers' labor intensity and improving production efficiency. During the threshing process, the threshed straw or stalks often require further processing for better use as feed, fertilizer, or other agricultural purposes. The crushing assembly is a key component for this task, and the crushing step is usually performed after the threshing step. Existing threshers rarely have a separate crushing assembly, and typically use an additional, separate crushing machine. This is not only time-consuming and labor-intensive, but also results in waste of straw or stalks.

[0003] Application No. 201922314865.6 discloses a multifunctional corn thresher, which includes a crushing chamber, a crushing blade and a storage chamber, etc. By providing a threshing chamber and a crushing chamber, corn can be threshed and crushed in a series of working processes, and the utility model can crush corn kernels and corn cobs at the same time, without the need for special equipment for crushing, saving time and effort to the greatest extent and reducing work costs.

[0004] However, in actual use, there are the following shortcomings:

[0005] Although a crushing shaft and crushing blades are set in the crushing chamber for crushing, the blades are fixed and the spacing and number cannot be adjusted. In addition, the crushing effect is poor and the material cannot be crushed into the required size, so the practicality is poor. Utility Model Content

[0006] The purpose of the present application is to provide a thresher crushing assembly, which solves the problem raised in the background art that although a crushing shaft and a crushing blade are arranged in a crushing chamber for crushing, the blades are fixed and the spacing and number cannot be adjusted, and the crushing effect is poor, and the material cannot be crushed into the required size, resulting in poor practicality.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a thresher crushing assembly, comprising a crushing bin, a crushing roller, a sleeve ring, a mounting plate and a baffle, a maintenance groove being provided at the top of the crushing bin, a bin cover being hingedly connected at the opening edge of the maintenance groove, a crushing roller being movably installed between the left and right inner walls of the crushing bin, the upper and lower sides of the surface of the crushing roller being fixedly connected to limit bars, and the surface of the crushing roller being movably sleeved and connected to the sleeve ring, and a plurality of mounting grooves being evenly distributed in a circular row on the surface of the sleeve ring, a mounting plate being laterally slidably connected to the inner side of the mounting groove, and a crushing blade being fixedly installed on the surface of the mounting plate.

[0008] In this technical solution, the driving motor is powered on and started to drive the crushing roller to rotate, thereby performing crushing operations. Through the sleeve ring, mounting groove, mounting plate and crushing blade, different crushing needs can be adapted. The sleeve ring can be freely slid on the surface of the crushing roller, and several sleeve rings can be slid in or out after disassembly to adjust the position and spacing of the crushing blade. The spacing of the crushing blade becomes larger or smaller, and different degrees of crushing operations can be performed to crush straw and the like into fragments of different sizes. If the crushing blade is damaged, the corresponding mounting plate can be slid out of the mounting groove, and then a new mounting plate and crushing blade can be replaced. The operation is relatively convenient, which improves the convenience and practicality of the device. At the same time, the slot and baffle can make the crushing more complete. After feeding into the crushing bin, the baffle blocks the outlet, and the crushed material is blocked until it is completely cut by the crushing blade and the crushing teeth on the upper bin cover. At this time, the baffle is pulled out to discharge the fragments to avoid partial discharge without completing the cutting, thereby improving the crushing efficiency of the device.

[0009] As an optional solution of the technical solution of the present application, an upper mounting hole is provided at the top of the mounting groove, a lower mounting hole is provided on the surface of the mounting plate, and mounting bolts are threadedly connected to the inner sides of the upper mounting hole and the lower mounting hole.

[0010] As an optional solution of the technical solution of the present application, a plurality of crushing teeth are evenly distributed and fixedly installed on the bottom of the bin cover.

[0011] As an optional solution of the technical solution of the present application, a slot is provided at the top of the compartment cover on one side of the maintenance slot, and a baffle is vertically slidably connected to the inner side of the slot.

[0012] As an optional solution of the technical solution of the present application, a driving motor is fixedly installed on the outer side wall of the crushing bin facing one end of the crushing roller, and the tail end of the transmission shaft of the driving motor is fixedly connected to the crushing roller.

[0013] As an optional solution of the technical solution of the present application, the top end of the sleeve ring is threadedly connected with a fixing bolt.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The present application can adapt to different crushing needs through the sleeve ring, mounting groove, mounting plate and crushing blade. The sleeve ring can be freely slid on the surface of the crushing roller, and several sleeve rings can be slid in or out after disassembly to adjust the position and spacing of the crushing blades. The spacing of the crushing blades can be increased or decreased, and different degrees of crushing operations can be performed to crush straw and the like into fragments of different sizes. If the crushing blade is damaged, the corresponding mounting plate can be slid out of the mounting groove, and then a new mounting plate and crushing blade can be replaced. The operation is relatively convenient, which improves the convenience and practicality of the device.

[0016] 2. This application can make the crushing more complete through the slots and baffles. After the material is fed into the crushing bin, the baffle blocks the outlet and the crushed material is blocked until it is completely cut by the crushing blades and the crushing teeth on the upper bin cover. At this time, the baffle is pulled out to discharge the fragments, avoiding partial discharge without completing the cutting, thereby improving the crushing efficiency of the device.
