Technical Field

The invention relates to the technical field of vegetable planting, in particular to a tomato sorting device.

Background

Along with the rise of the social living standard, the variety of agricultural and sideline products is more and more abundant, the yield is also continuously improved, more and more people begin to pay attention to the quality of the products when selecting to buy related products, and people can select to buy better products under the condition that the economic conditions of the people allow. At present, merchants generally divide the same product into equal stages, distinguish and separately package the same product according to the quality, the volume and the product phase of the product, and price and sell the same product respectively. Therefore, when each wholesaler purchases fruits and vegetables and the like from the peasant household, the peasant household is required to perform primary selection according to the needs of the peasant household, and the fruits and the vegetables are primarily subpackaged according to the requirements on quality and volume. The tomato is one of the main vegetables in China, contains rich organic acid, vitamins, lycopene and mineral elements, can improve the immunity and promote the gastrointestinal function, has multiple health-care functions of clearing away heat and toxic materials, protecting eyesight, beautifying and protecting skin, losing weight, protecting cardiovascular and cerebrovascular systems, delaying aging, resisting cancer, inhibiting cancer and the like, and is popular among people. In the prior art, tomatoes are generally sorted by pure hands, so that the sorting efficiency is low, the labor intensity is high, the ripening time of the tomatoes is concentrated, and if the tomatoes are not picked, sorted, packaged and sold in time, the tomatoes deteriorate or even rot after a long time, and economic loss is brought to farmers. Therefore, it is necessary to research and develop a tomato sorting device which has simple structure, low cost, reliable use, simplicity and rapidness.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the tomato sorting device, which can be used for quickly sorting tomatoes and improving the sorting efficiency, and has the advantages of simple structure, low manufacturing cost and reliability in use.

The technical scheme of the invention is as follows: the utility model provides a tomato sorting device, which comprises a frame, a feeding device, letter sorting groove and collection basket, letter sorting groove slope sets up, be provided with the discharge gate on the letter sorting groove, discharge gate department disposes the valve, the valve passes through pressure switch real time control, pressure switch sets up in discharge gate the place ahead, make the tomato pass through pressure switch again through the discharge gate earlier, when the weight of a tomato surpasss pressure switch's rated pressure value, the valve that corresponds is opened, make this tomato from the discharge gate whereabouts that corresponds, the below of discharge gate is provided with the collection basket.

Furthermore, a plurality of discharge holes are formed in the sorting groove.

Further, the discharge ports are arranged along the length direction of the sorting groove.

Further, the diameter of the discharge port is larger than the corresponding size of the tomatoes to be sorted, so that the tomato can not be clamped at the discharge port during sorting.

Furthermore, the pressure switches for controlling the opening and closing states of the valves at the discharge openings have different rated pressure values, and the rated pressure value of the pressure switch is larger as the vertical height is higher.

Furthermore, a collecting basket is arranged below each discharge port, and a funnel is arranged between each collecting basket and each discharge port.

Furthermore, the surfaces of the funnel and the collecting basket are provided with buffer layers for preventing the tomatoes from being damaged due to collision when contacting with the tomatoes.

Further, the inner space of the collecting basket is divided into a plurality of parallel collecting cavities by the partition plates, the sieve plate is arranged above the collecting basket and is obliquely arranged, and the diameter of the filtering holes in the sieve plate corresponds to the space divided by the collecting basket, so that tomatoes with similar sizes fall into the same collecting cavity of the collecting basket.

Furthermore, the diameter of the filter holes at the vertical positions on the sieve plate is smaller than that of the filter holes at the lower positions.

Furthermore, a vibrator is arranged on the sieve plate, and the tomatoes on the sieve plate can slide more easily under the action of the vibrator.

The invention has the beneficial effects that: according to the tomato sorting device provided by the invention, the tomatoes are firstly loaded in different collecting baskets by weight through the pressure switch, meanwhile, the collecting baskets are provided with the sieve plates, the tomatoes of different sizes are classified by using the filtering holes of different diameters on the sieve plates, and finally, the classification of the tomatoes in two dimensions of weight and size is realized.

Detailed Description

The present invention will be described in further detail with reference to specific examples, wherein the steps and details not specifically described in the present example are prior art.

Examples

As shown in fig. 1-2, the present embodiment is a tomato sorting device, which includes a frame 1, a feeding device 2, a sorting trough 3 and a collecting basket 4, wherein the feeding device 2 and the sorting trough 3 are both disposed on the frame 1, the frame 1 is further provided with rollers 11 for easy movement, the sorting trough 3 is disposed in an inclined manner, so that tomatoes flowing in from the feeding device 2 can naturally slide down along the sorting trough 3 under the action of gravity, the feeding device 2 can control the flowing speed of the tomatoes, and it is ensured that the individual tomatoes sequentially and orderly flow into the sorting trough 3. The feeding device 2 is prior art and will not be described in detail.
