Description

A tea fresh leaf screening machine

technical field

The utility model relates to the technical field of tea processing equipment, in particular to a screening machine for fresh tea leaves.

Background technique

Tea is a traditional economic crop in my country. The tea industry has a great impact on the regional economy and the income of the people in the tea areas. In recent years, with the remarkable improvement of the mechanization level of tea processing in my country, the standardized production capacity and production efficiency of tea have been greatly improved. The bottleneck is that in many areas, the picking of famous and high-quality tea is still done manually, and the picking efficiency is low. In addition, the labor cost has increased year by year in recent years, which seriously restricts the production efficiency of famous and high-quality tea. It is applied to the picking of famous and high-quality tea, which improves the picking efficiency. However, the quality of machine-picked tea is generally not as good as that of hand-picked tea. For the screening of machine-picked fresh leaves, the current fresh leaf screening equipment in my country is mainly multi-layer vibrating screen screening machines, which are easy to operate and low in cost. This kind of equipment is prone to feeding competition during use. Screening is often blocked due to the accumulation of branches and old leaves, which affects the normal operation and screening effect of the screening equipment, resulting in low production efficiency, and the grading effect is not obvious, failing to meet the grading requirements of different grades of famous tea fresh leaf raw materials.

The fresh tea leaf screening machine is characterized in that the filter stem sieve plate and the grading sieve plate are arranged obliquely in the screening box, and the inclination directions are alternated.

The fresh tea leaf sieving machine described above is characterized in that the sieve holes of the grading sieve plates decrease sequentially from the upper layer to the lower layer.

The fresh tea leaf screening machine described above is characterized in that the supporting legs of the frame are provided with height-adjustable bases.

Compared with the prior art, the beneficial effect of the utility model is that the structural design is reasonable, and by adopting the anti-blocking feed hopper and the filter stem sieve plate, it is ensured that feeding and screening blockages are not easy to occur during the operation process, and the production capacity is improved. Efficiency, by using different levels of grading sieves, the grading requirements of different grades of famous and high-quality tea fresh leaf raw materials can be achieved.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings of the description, and specific implementation methods will be given.

As shown in Figure 1, the utility model 1 a kind of tea fresh leaf screening machine comprises frame 1, vibrating spring 2, vibrating mechanism and screening box 5, in order to make screening box 5 under the effect of vibrating mechanism, along with vibrating mechanism Movement together, the vibration mechanism is set on the frame 1 through the vibration spring 2, the vibration mechanism is composed of the vibration plate 3 and the vibration motor 4, the vibration plate 3 and the vibration motor 4 are rigidly connected by bolts, the vibration source is generated by the vibration motor 4, and the screening box 5 is set on the vibrating plate 3, and the top of the screening box 5 is provided with an anti-blocking feed hopper 6. In order to prevent the feeding from clogging, the anti-blocking feed hopper 6 is composed of a hopper, a feed conduit, a material distribution plate and a vibrator. Composition, the junction of the hopper and the feed conduit is provided with a material distribution plate, the side wall of the feed hopper is provided with a vibrator, and the uppermost layer inside the screening box 5 is provided with a filter stem sieve plate 7, which can effectively screen out the branches, To prevent clogging, three layers of grading sieve plates 8 are sequentially arranged below the filter stem sieve plate 7, and sieve holes 9 are arranged on the grading sieve plate 8. A stalk outlet 10 is provided on the wall corresponding to the filter stalk sieve 7 , and a tea outlet 11 is provided on the side wall of the screening box 5 corresponding to the grading sieve 8 .
