Description

Technical Field

[0001] The utility model relates to the field of seed screening equipment, in particular to a rice seed combined cleaning machine. Background Art

[0002] Seed cleaning is an important part of seed processing, and its purpose is to separate seeds from inclusions to improve seed purity and quality. Seed cleaning methods can be classified according to seed size, aerodynamic properties, and density.

[0003] In the seed cleaning process, the role of machinery is crucial; machinery can choose appropriate models and configurations according to different cleaning requirements to achieve the best cleaning effect.

[0004] Rice seeds need to be cleaned after harvest. The existing cleaning requires the use of a variety of tools to remove the rice seeds from the awns, and then winnow, screen and separate the rice from the husks. This requires multiple processes and multiple equipment, which greatly reduces the efficiency of rice seed cleaning. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rice seed combined cleaning machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rice seed combined cleaning machine comprises a fixed frame, a de-awning machine is installed on the top of the fixed frame, a winnowing machine is installed on the fixed frame at the bottom of the de-awning machine, a screening machine is installed on the fixed frame at the bottom of the winnowing machine, a rice-rough separator is installed on the fixed frame at the bottom of the screening machine, a lifting machine is fixedly arranged on one side of the fixed frame, and a moving mechanism for facilitating the movement of the device is arranged at the bottom of the fixed frame. When in use, the lifting machine lifts the rice seed raw materials and sends them into the de-awning machine for de-awning. After completion, the winnowing machine performs winnowing to remove light debris and then sends them into the screening machine for screening. Qualified rice seeds enter the rice-rough separator for separation. In this way, the rice seed cleaning work can be completed by one set, which is in place at one time and greatly improves the rice seed cleaning efficiency.

[0007] Preferably, the moving mechanism includes a fixed plate, a motor, a support frame, a first gear, a rotating shaft, a second gear, a screw, a perforation, a positioning rod, a moving wheel and a tip block, the fixed plate is fixed to the outside of the fixed frame, the support frame is fixed to the top position of the fixed plate, the motor is fixed to the bottom end of the support frame, the rotating shaft is fixed to the output end position of the motor, the first gear is fixed to the bottom end position of the rotating shaft, the second gear is movably embedded in the top end of the fixed plate, the screw passes through the center position of the second gear through a thread, the tip block is fixed to the bottom end position of the screw, the perforation is opened on the support frame, the positioning rod is fixed to the top end of the screw, The wheel is fixed at the bottom end of the fixed plate. The device is moved by the motion wheel before use. When in use, the motor is started, and the motor drives the rotating shaft to rotate, thereby driving the first gear to rotate, causing the second gear to rotate. Since the positioning rod positions the screw rod to prevent the screw rod from rotating, relative rotation occurs between the screw rod and the second gear rod, and the screw rod moves downward along the second gear rod, driving the tip block to move downward until it contacts the destination position, thereby fixing the entire device to facilitate fixed use of the device. When used in an uneven position, the motor on the side off the ground is started separately, so that the screw rod continues to move downward until it contacts the ground, thereby ensuring the stability of the device.

[0008] Preferably, the output end of the deawning machine is located at the output end of the winnowing machine, the output end of the winnowing machine is located at the input end of the screening machine, and the output end of the screening machine is located at the input end of the rice-rough separator.

[0009] Preferably, the perforation shape is rectangular.

[0010] Preferably, the positioning rod has a rectangular cross-section and moves through the through hole.

[0011] Preferably, the first gear is meshed with the second gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, the lifting machine lifts the rice seed raw materials and sends them into the awn removing machine for awn removing. After the awn removing is completed, the winnowing machine performs winnowing to remove light debris, and then sends them into the screening machine for screening. Qualified rice seeds enter the rice-rough separator for separation. In this way, the rice seed cleaning work can be completed in one go, which greatly improves the rice seed cleaning efficiency.

[0014] 2. The utility model moves the device by means of a moving wheel before use, and starts the motor when in use. The motor drives the rotating shaft to rotate, thereby driving the first gear to rotate, causing the second gear to rotate. Since the positioning rod positions the screw to prevent the screw from rotating, relative rotation occurs between the screw and the second gear. The screw moves downward along the second gear, driving the tip block to move downward until it contacts the destination position, thereby fixing the entire device and facilitating the fixed use of the device. When used in an uneven position, the motor on the side off the ground is started separately, so that the screw continues to move downward until it contacts the ground, thereby ensuring the stability of the device.
