Abstract
Description
Technical Field
[0001] This utility model relates to the field of threshing machine technology, specifically a multi-functional adjustable threshing machine. Background Technology
[0002] A thresher is an agricultural machine used to remove grain from the ear of grain. There are various types of threshers, among which the airflow cleaning thresher combines threshing and airflow cleaning functions. This type of thresher mainly consists of two parts: threshing and airflow cleaning. The threshing mechanism is similar to that of a general simple thresher, while the airflow cleaning mechanism consists of a projector, separator, impurity discharge cylinder, fan, and air duct. Its working principle is to use the fan to generate negative pressure airflow, which separates the grain based on the different floating speeds of the husk, stalk, and impurities due to their different masses. In existing technology, when threshing different crops, the required threshing time varies for different crops, and the guide blocks of the threshing bin in traditional technology cannot adjust the threshing time of the crop in the threshing device, resulting in increased loss rates for different crops during threshing.
[0003] For example, patent publication number CN221930745U describes a rice thresher, which includes a worktable, a threshing box fixedly connected to the top right side of the worktable, a roller rotatably connected inside the threshing box, a sealing plate fixedly connected to the top left side of the threshing box, a transparent flip-top rotatably connected to the top right side of the threshing box, a feeding window on the side of the transparent flip-top near the sealing plate, a drive device on the left side of the worktable, a material discharge structure fixedly connected to the top of the worktable near the right side of the threshing box, a collection box at the bottom of the worktable corresponding to the material discharge structure, a first drawer and a second drawer movably connected to the left and right sides of the front of the collection box, and an air separator on the left side of the collection box. This utility model can avoid the abnormal increase in friction and heat during the use of traditional threshers, thereby reducing the motor load and extending the overall service life of the device. However, it addresses the problem that when threshing different crops, the required threshing time varies, and the guide block of the threshing chamber in traditional technology cannot adjust the threshing time of the crop in the threshing device, leading to an increased loss rate for different crops during threshing.

[0008] Preferably, the guide plate is detachably connected to the mounting plate by mounting bolts, and the mounting plate and the guide plate are arranged perpendicular to each other, so that the guide plate can be installed and replaced, and can be used to shield and guide crops.
[0009] Preferably, the top of the locking bolt penetrates through the threshing machine body and partially extends outside the threshing machine body. The locking bolt matches the locking screw hole, and the locking bolt is threadedly connected to the locking handwheel through the locking screw hole, so that the locking handwheel and the locking bolt can be used to lock the guide plate.
[0010] Preferably, the threshing mechanism includes a threshing motor and a threshing frame. The threshing frame is rotatably connected to the inside of the threshing machine body. The threshing motor is fixedly installed on the threshing machine body. Both the output shaft end of the threshing motor and the end of the threshing frame are fixedly connected to pulleys. A belt is sleeved between the two pulleys to enable threshing of crops.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a multi-functional adjustable thresher, including a thresher body 1. The outer shell of the thresher body 1 is equipped with a buckle, allowing for easy opening of the shell to facilitate inspection and adjustment of internal components. The thresher body 1 has a feed inlet 3 and a discharge outlet 4. A thresher mechanism 5 is installed inside the thresher body 1. An adjustable mechanism 2 is located on one side of the top of the thresher mechanism 5. The adjustable mechanism 2 can be installed at the front, back, both sides, and top of the thresher body 1. Multiple gears can be adjusted through the adjustable mechanism 2, ranging from two to ten gears, or from one to more, to adjust the threshing time of different crops within the thresher body 1, thereby improving the threshing effect and effectively reducing threshing loss.
[0021] The adjusting mechanism 2 includes multiple mounting plates 201. Each mounting plate 201 has a guide plate 203 fixedly connected to its top end via mounting bolts 202. The guide plate 203 is detachably connected to the mounting plate 201 via mounting bolts 202, and the mounting plates 201 and guide plates 203 are arranged perpendicularly to each other, allowing for the installation and replacement of the guide plate 203. The guide plate 203 also serves to shield and guide crops. Each mounting plate 201 has a locking bolt 204 fixedly connected to its bottom end. The bottom ends of the multiple mounting plates 201 are rotatably connected to the threshing machine body 1 via locking bolts 204, allowing the mounting plates 201 and guide plates 203 to rotate left and right. The angle can be adjusted to change the threshing time of different crops. Multiple mounting plates 201 are evenly arranged inside the threshing machine body 1, so that multiple gears can be adjusted to adjust the threshing time of different crops. The locking bolt 204 is equipped with a locking handwheel 205. The locking handwheel 205 has a locking screw hole 206 inside. The top of the locking bolt 204 passes through the threshing machine body 1 and partially extends to the outside of the threshing machine body 1. The locking bolt 204 matches the locking screw hole 206. The locking bolt 204 is threadedly connected to the locking handwheel 205 through the locking screw hole 206, so that the locking handwheel 205 and the locking bolt 204 can lock the guide plate 203.
[0022] Please see Figure 1-2 The threshing mechanism 5 includes a threshing motor 501 and a threshing frame 502. The threshing frame 502 is rotatably connected to the inside of the threshing machine body 1. The threshing motor 501 is fixedly installed on the threshing machine body 1. Pulleys 503 are fixedly connected to the output shaft end of the threshing motor 501 and the end of the threshing frame 502. A belt 504 is sleeved between the two pulleys 503. The threshing motor 501 can drive the threshing frame 502 to rotate by means of the pulleys 503 and the belt 504. The threshing frame 502 performs threshing operations on the crops.
[0023] During operation, rotate the locking handwheel 205 to move it along the locking bolt 204 away from the threshing machine body 1, releasing the constraint on the guide plate 203. Then rotate the guide plate 203 to adjust its angle. After adjustment, rotate the locking handwheel 205 in the opposite direction to lock it tightly against the surface of the threshing machine body 1 with the locking bolt 204, fixing the guide plate 203. Multiple settings can be adjusted to adjust the threshing time in the threshing machine body 1 according to different crops, so that more and cleaner grains are threshed from the crop stalks, improving the threshing effect and effectively reducing the threshing loss rate.
