[0025] This utility model provides the following technical solution: a screening machine 100 that is easy to operate, including a frame 10, a transmission assembly 20, a screen bucket 30 and a discharge slide 40; the top two sides of the frame 10 are respectively provided with a plurality of pulleys 101, the screen bucket 30 is movably located on the pulleys 101 on the top two sides of the frame 10, the screen bucket 30 is provided with a plurality of screening holes 301, the transmission assembly 20 is fixedly installed on the frame 10, the transmission assembly 20 is connected to the screen bucket 30 for transmission, the transmission assembly 20 is used to drive the screen bucket 30 to reciprocate linearly, and the discharge slide 40 is fixedly installed on the frame 10 and corresponds to the bottom end of the screen bucket 30.

[0026] In the easy-to-operate screening machine 100 provided in this embodiment, when screening broccoli seeds for impurities (such as branches, leaves, or stones), a certain amount of broccoli seeds with impurities are poured into the screening hopper 30. Then, the transmission component 20 drives the screening hopper 30 to make a linear reciprocating motion. During the linear reciprocating motion, the screening hopper 30 shakes the broccoli seeds so that they fall from the screening holes 301 of the screening hopper 30 into the discharge chute 40 for feeding. The user can use an external container to connect to the discharge end of the discharge chute 40 to collect the screened broccoli seeds. After the screening hopper 30 screens and discharges the broccoli seeds, only impurities (such as branches, leaves, or stones) remain in the screening hopper 30. The user can manually clean and remove the remaining impurities from the screening hopper 30. Broccoli seeds have a physiological diameter between 0.8-1.1 mm. The diameter of each screening hole 301 on the sieve hopper 30 is set to 1.1 mm, allowing the sieve hopper 30 to screen the broccoli seeds through these 1.1 mm diameter holes. Impurities larger than 1.1 mm in diameter are collected in the sieve hopper 30 for user cleaning. In this invention, the transmission assembly 20 drives the sieve hopper 30 to perform linear reciprocating motion, enabling it to screen the broccoli seeds and collect impurities for user cleaning. This screening machine has the advantages of high processing efficiency, convenient operation, simple structure, and low manufacturing cost.

[0027] In some embodiments, the transmission assembly 20 includes a transmission motor 201, a transmission belt 202, a rotating disk 203, a transmission shaft 204, a hinge shaft 205, and two bearings 206. The transmission motor 201 is fixedly mounted on the frame 10, and the rotating disk 203 is located at the top of the transmission motor 201. The transmission belt 202 is connected between the output end of the transmission motor 201 and the rotating disk 203. The transmission shaft 204 is fixedly mounted through the center of the rotating disk 203. The two bearings 206 are fixedly mounted on the frame 10 and are located on both sides of the rotating disk 203. The two bearings 206 are rotatably connected to the front and rear sections of the transmission shaft 204, respectively. The end of the transmission shaft 204 on the rotating disk 203 is hinged to one end of the hinge shaft 205, and the other end of the hinge shaft 205 is hinged to the hinge seat 303 provided on the side of the screen hopper 30.

[0028] In specific implementation: When the transmission assembly 20 drives the sieve 30 to perform linear reciprocating motion, the output end of the transmission motor 201 drives the rotating disk 203 to rotate via the transmission belt 202. As the rotating disk 203 rotates, since one end of the transmission shaft 204 on the rotating disk 203 is hinged to the hinge shaft 205, the rotating disk 203 can drive the hinge shaft 205 to perform linear reciprocating motion via the transmission shaft 204. When the hinge shaft 205 is driven to perform linear reciprocating motion, since the other end of the hinge shaft 205 is hinged to the hinge seat 303 on the side of the sieve 30, the hinge shaft 205 can drive the sieve 30 to perform linear reciprocating motion. During this linear reciprocating motion, the broccoli seeds within the sieve 30 can be shaken for screening. When the transmission shaft 204 rotates, two bearings 206 support the front and rear sections of the transmission shaft 204 respectively. With this configuration, the transmission component 20 can effectively drive the sieve bucket 30 to perform linear reciprocating motion to shake the broccoli seeds and complete the screening.

[0029] In some embodiments, the end of the drive shaft 204 on the rotating disk 203 is hinged to one end of the hinge shaft 205 by a fixed insertion of a first pin 2051, and the other end of the hinge shaft 205 is hinged to the hinge seat 303 provided on the side of the sieve hopper 30 by a fixed insertion of a second pin 2052.

[0030] In specific implementation: a first pin 2051 is fixedly inserted between the end of the drive shaft 204 and one end of the hinge shaft 205, so that the end of the drive shaft 204 and one end of the hinge shaft 205 can be moved to achieve hinge connection; a second pin 2052 is fixedly inserted between the other end of the hinge shaft 205 and the hinge seat 303 provided on the side of the screen hopper 30, so that the other end of the hinge shaft 205 and the hinge seat 303 provided on the side of the screen hopper 30 can be moved to achieve hinge connection.

[0031] In some embodiments, the bottom sides of the sieve 30 are respectively provided with grooves 302, and the grooves 302 on both sides of the bottom of the sieve 30 respectively accommodate the pulleys 101 on both sides of the top of the frame 10.

[0032] In specific implementation: When the transmission assembly 20 drives the screen bucket 30 to make linear reciprocating motion, the screen bucket 30 slides on the pulleys 101 on the top sides of the frame 10 through the sliding grooves 302 on both sides of the bottom. Since the sliding grooves 302 on both sides of the bottom of the screen bucket 30 respectively accommodate the pulleys 101 on both sides of the top of the frame 10 for limiting, the screen bucket 30 can slide linearly and reciprocally on the pulleys 101 on both sides of the top of the frame 10 along the linear trajectory of the sliding grooves 302 on both sides of the bottom, so that the screen bucket 30 does not derail from the pulleys 101 on both sides of the top of the frame 10.

[0033] In some embodiments, a plurality of lockable rollers 102 are provided at the bottom of the frame 10.

[0034] In practical implementation: When it is necessary to move the screening machine, the user can unlock the lockable rollers 102 at the bottom of the frame 10, and then push the frame 10 by hand to move the screening machine. When the screening machine does not need to be moved, the user can lock the lockable rollers 102 at the bottom of the frame 10 to prevent the screening machine from slipping. The lockable rollers 102 are commonly used in the prior art with locking functions.

[0035] In some embodiments, both the frame 10 and the sieve 30 are made of iron, and the surfaces of both the frame 10 and the sieve 30 are coated with anti-rust paint.

[0036] In practice: Both the frame 10 and the screen bucket 30 are made of iron, which has the advantage of being hard and not easily damaged. The surfaces of the frame 10 and the screen bucket 30 are coated with anti-rust paint to prevent them from being corroded by rust, thereby extending their service life.

[0037] In some embodiments, the drive motor 201 and the two bearings 206 are both fixed to the frame 10 by screws.

[0038] In practice: the drive motor 201 is fixed to the frame 10 with screws so that the drive motor 201 is stably mounted on the frame 10 for operation. Both bearings 206 are fixed to the frame 10 with screws so that the two bearings 206 can stably support the rotation of the drive shaft 204 on the rotating disk 203.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
