Description

A kind of peanut seed sorting equipment

technical field

The utility model relates to the field of seed screening equipment, in particular to peanut seed sorting equipment.

Background technique

Whether the grains are full or not is an important parameter to measure the quality of crop seeds. The empty seeds are not only related to the thousand-grain weight and vigor index of the seeds, but also directly affect the germination characteristics and survival ability of the seeds. Screening seeds with full grains is an important measure to improve the use efficiency of crop seeds and make them emerge neatly. Peanut is an important oil crop and economic crop in my country. The shape of peanut seeds is irregular, most of them are oval, and the kernel weight and particle size of the same variety vary greatly, which is not conducive to the sorting of seeds. Manual sorting is heavy workload, tedious and time-consuming, and there are many uncontrollable factors. At present, there is a lack of effective grading and sorting equipment for peanut seeds, and the present invention can solve this technical problem efficiently and quickly.

At present, hand sieves with different mesh numbers are often used in conventional grain selection, and the stones and soil mixed in the seeds are removed by hand or mechanical vibrating sieves, and the hand sieves with different mesh numbers are used for grading. The method causes dust to fly and sand and gravel to scatter, causing pollution to the environment. At the same time, the use of mechanical screening machines generally has disadvantages such as high price, high noise, and low-quality screening seeds; in addition, the seeds themselves will have moisture during storage, which will easily lead to mildew and affect the quality and germination rate of peanut seeds.

Therefore, a kind of seed sorting equipment that can complete irregular peanut seed grading, remove impurities, have low manufacturing cost, have no impact on the environment and can guarantee the quality of peanut seeds needs to be developed urgently.

Utility model content

In view of the above existing problems, the utility model provides a sorting equipment for peanut seeds, which can realize classification of peanut seeds and removal of sundries, and does not generate dust emission while ensuring the quality of peanut seeds.

In order to achieve the above object, the utility model adopts the following technical solutions. A sorting equipment for peanut seeds, which is composed of a shell, a fan, a cyclone separator, and a grading sieve; the shell is provided with a material inlet, a material outlet, and an air outlet; the grading sieves are parallel to each other and arranged obliquely In the casing; the air inlet end of the fan is connected to the cyclone separator through the air pipe, and the air outlet end of the fan is connected to the dust bag through the air pipe; It is composed of a seed sieve; the sieve hole of the seed sieve is oval, which is more suitable for screening oval peanut seeds.

Further, the seed sieve is provided with several layers, and the area of the upper mesh is 1.2-2.5 times the area of the lower mesh, and the ratio of the long axis length to the short axis length of the seed sieve holes at all levels is the same. classification screening.

Furthermore, the air inlet is provided with an airflow deflector, which can form a swirling flow of the incoming air, instead of the traditional mechanical vibration, and better protect the seeds from mechanical damage.

Further, the cyclone separator is provided with a collection tank, which can collect dust and peanut shells with a relatively light specific gravity through the cyclone separator and dust-removing cloth bag to prevent pollution to the environment.

When in use, turn on the fan and pour the peanut seeds from the feed inlet. Since the air inlet is equipped with an air deflector, the airflow forms a swirling flow in the casing, and the dust with a lighter specific gravity and residual peanut shells can be sucked through the air duct. In the collection tank of the cyclone separator, the larger individual peanut seeds stay on the uppermost sieve plate, and the peanut seeds of different sizes fall into the lower sieve plate through the oval sieve holes in turn, and the specific gravity sand particles fall into the uppermost sieve plate. The bottom of the gravel screen. Thereby completing peanut seed grading.

The utility model has the advantages that it can realize classification of peanut seeds, remove sundries and ensure the quality of peanut seeds, while not discharging dust into the environment.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Peanut seed sorting equipment is composed of a housing 1, a fan 2, a cyclone separator 3, and a grading sieve plate 4; the housing 1 is provided with an inlet 11, an outlet 12, and an air outlet 13; the grading sieve The plates 4 are parallel to each other and arranged obliquely in the housing 1; the air inlet end of the fan 2 is connected to the cyclone separator 3 through the air pipe 32, and the air outlet end of the fan 2 is connected to the dust bag 21 through the air pipe 32. connected;

The grading sieve plate is composed of a debris sieve, a gravel sieve and a seed sieve; the seed sieve 41 is oval, and the seed sieve is provided with two layers, and the upper sieve area is 1.2-2. 2.5 times, the ratio of the major axis length and the minor axis length of the seed sieve holes at all levels is the same, and the feed inlet 11 is provided with an air flow deflector 14, which can make the air intake form a swirling flow, replace the traditional mechanical vibration, and more The seeds are well protected from mechanical damage; the cyclone separator 3 is provided with a collection tank 31, which can collect dust and peanut shells with a lighter specific gravity through the cyclone separator 3 and the dust bag 21 to prevent pollution to the environment.

When in use, turn on the blower 2 and pour the peanut seeds from the feed port. Since the feed port 11 is provided with an air flow deflector 14, the air flow forms a swirling flow in the housing 1, and the dust with a light specific gravity can pass through the peanut shells. The air pipe 32 is sucked into the collection tank 31 of the cyclone separator 3, and the peanut seeds with larger individual stay on the uppermost sieve plate, and the peanut seeds of different sizes fall into the lower sieve plate through the elliptical sieve holes in turn, and the specific gravity is large.
