Description

a screening machine

technical field

The utility model belongs to the technical field of machinery and relates to a screening machine.

Background technique

Screening machines are mainly used for the separation and selection of semi-finished products. For example, in pharmaceutical companies, when removing pills that do not meet the specified size, screening machines are often used. Screening machines are also widely used in agricultural production.

In the patent (CN102806196A), a screening machine is disclosed, including a housing, a motor and a bracket. The bottom of the housing is fixed with a bracket. The housing is controlled by an external motor. There is a screening chamber inside the housing, and a screen is provided in the screening chamber. , there are sieve holes on the sieve, and a discharge port is set at the bottom of the screening chamber. The advantages are that the screened particles are small, of good quality, simple in structure, and easy to use. However, this screening machine only makes the granular products Separated, the screening efficiency is low, and it is easy to block the screening holes when screening rough products.

Contents of the invention

The purpose of this utility model is to provide a screening machine for the above-mentioned problems in the existing technology. The technical problem to be solved by this utility model is how to make the screening net shake up and down, so as to screen the products.

The purpose of the utility model can be achieved through the following technical solutions: a screening machine, including a bracket, characterized in that, a motor is fixedly arranged on the bracket, the screening machine also includes a pendulum, the pendulum The lower end of the rod is hinged on the bracket, a runner is arranged on the output shaft of the motor, and a connecting rod is arranged at an eccentric position of the runner, and the connecting rod is hinged on the swing rod On, the upper end of the swing rod is fixedly provided with a screen.

The working principle of the utility model is: after the motor is powered on, it drives the runner to rotate, and the connecting rod arranged at the eccentric position of the runner reciprocates along with the rotation of the runner, and one end of the connecting rod is hinged on the swing rod. The lower end of the swing rod is hinged on the bracket, and the connecting rod pulls the swing rod to move, so that the screen mesh fixed on the upper end of the swing rod vibrates in the vertical direction and at the same time swings on the horizontal plane, so that the screening is more thorough.

In the above screening machine, several screen holes are evenly opened on the bottom of the screen. Put the product on the screen, start the motor, and make the product vibrate in the screen, so that the defective or finished products are leaked under the screen.

In the above screening machine, a retaining edge is provided at the edge of the screen. The edge of the shelf is higher than the plane of the screen, and can be placed on the product to slide off the edge during the vibration process.

In the above screening machine, a material receiving plate is provided at the lower end of the screen, and a material receiving port is provided at the edge of the material receiving plate. A material receiving container is placed under the material receiving plate, and the product leaked from the sieve hole falls onto the material receiving plate, and slides from the material receiving port into the material receiving container.

In the above screening machine, a supporting plate is fixedly arranged on the support, and the motor is fixedly arranged on the supporting plate. Since the upper end of the entire support is in a vibrating state, the motor needs to be fixed firmly to ensure that the screen is relatively stable.

In the above screening machine, several supporting feet are provided at the lower end of the support. The supporting feet are fixed on the ground, and the whole support is held up.

Compared with the prior art, the utility model has the following advantages:

1. Through the design of the rotating wheel and the pendulum, the screening machine can realize the vibration of the screen to ensure the efficiency of screening products and the screening is thorough.

2. The bottom of the screen of this screening machine is evenly equipped with screen holes, which can separate products of different sizes.

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of screening machine comprises a support 1, and a motor 2 is fixedly arranged on the support 1, and this screening machine also comprises a fork 3, the The lower end is hinged on the bracket 1, a runner 4 is arranged on the output shaft of the motor 2, and a connecting rod 5 is arranged at the eccentric position of the runner 4, and the connecting rod 5 is hinged on the swing rod 3, and the upper end of the swing rod 3 is fixed A sieve 6 is provided, and the bottom of the sieve 6 is evenly provided with several sieve holes 62, the product is placed on the sieve, the motor 2 is started, and the product is vibrated in the sieve 6, thereby leaking defective or finished products to the Under the sieve 6, the edge of the sieve 6 is provided with a shelf edge 61, which is higher than the plane of the sieve 6, and can be placed on the product to slide from the edge during the vibration process. The lower end of the sieve 6 is provided with a joint. Material plate 7, a material receiving port 71 is provided at the edge of material receiving plate 7, a material receiving container is placed below the material receiving plate 7, and the product leaked from sieve hole 62 falls on the material receiving plate 7, from the material receiving plate 7 The mouth 71 slides into the material receiving container, a support plate 8 is fixedly arranged on the support 1, and the motor 2 is fixedly arranged on the support plate 8.
