Description

Fruit and vegetable transportation fresh-keeping equipment

Technical Field

The invention relates to the technical field of fruit and vegetable fresh-keeping equipment, in particular to fruit and vegetable transportation fresh-keeping equipment.

Background

The transportation of fruits and vegetables is the market supply for regulating the fruits and vegetables, the complementary deficiency, the bridge for producing and consuming the fruits and vegetables, and the important link essential for the economic development of commodity. In the transportation process, the transportation quality can be ensured only by meeting the conditions required by the fruits and vegetables in the transportation process as much as possible according to the biological characteristics of the fruits and vegetables. In the fruit and vegetable transportation process, fruit and vegetable transportation fresh-keeping equipment is needed. The most used fruit and vegetable fresh-keeping equipment at present comprises an independent box body, and dry ice is placed in the box body to keep fruits and vegetables fresh. Also a special fruit and vegetable fresh-keeping device which uses air-conditioned storage fresh-keeping.

Basic principle of air-conditioning fresh-keeping technology: on the basis of a sealed warehouse body and refrigeration, the air conditioning parameters are set according to the physiological characteristics of different fruits, the oxygen concentration in a storage space is manually reduced, the carbon dioxide gas concentration is increased, the humidity environment of different fruits and vegetables is kept to the set air conditioning parameters through special detection equipment and control equipment, and the air parameters are kept in the warehouse during the whole storage period, so that the respiration of the fruits is inhibited, the fruits are in a normal and low-consumption metabolic state, and the purpose of fresh-keeping of the fruits is achieved.

Whatever fruit and vegetable fresh-keeping equipment is used for transporting fruits and vegetables, the transportation effect is affected by factors such as transportation vibration intensity, ambient temperature, humidity, air components, product packaging, stacking, loading and unloading and the like. Wherein, the fruit and vegetable fresh-keeping equipment adopting the air-conditioning fresh-keeping technology is less influenced by the factors of ambient temperature, humidity and air components, and even has no influence. However, whatever fruit and vegetable fresh-keeping equipment is affected by the intensity of the transportation vibration. Generally, environmental conditions in the transportation process are difficult to control, the requirements of fruit and vegetable fresh-keeping are difficult to meet, and particularly, the road jolts are extremely easy to cause adverse effects on the quality of the fruits and vegetables. Namely, the existing fruit and vegetable fresh-keeping equipment is influenced by road jolt in the transportation process, the fruit and vegetable are easy to collide, and the quality of the fruit and vegetable is easy to be influenced by road jolt in the transportation process.

Therefore, a new fruit and vegetable transportation fresh-keeping device needs to be developed to solve the above problems.

Disclosure of Invention

The invention aims to solve the problem that the existing fruit and vegetable fresh-keeping equipment is influenced by road bump in the transportation process, so that the fruit and vegetable are easy to collide, and the quality of the fruit and vegetable is easy to be influenced by road bump in the transportation process.

In order to achieve the above purpose, the present invention adopts the following technical scheme:

The utility model provides a fruit vegetables transportation fresh-keeping equipment, includes fresh-keeping box, fresh-keeping box includes that fruit vegetables place the subassembly, fruit vegetables place the subassembly and place the box including fruit vegetables, fruit vegetables place the box in around its inner wall a week be equipped with the third elasticity buffer board, demountable installation has a plurality of fruit vegetables to place the board on the third elasticity buffer board. The fruit and vegetable placing plate is provided with a fruit and vegetable placing groove, and fruits and vegetables are placed in the fruit and vegetable placing groove. A first buffer component is arranged between the fruit and vegetable placement component and the inner wall of the fresh-keeping box body.

The first buffer components are arranged in pairs, and the number of the first buffer components is at least two. And the fruit and vegetable placement assemblies are detachably connected between each pair of first buffer assemblies.

In the fruit and vegetable transportation process, the transported fruit and vegetable is placed on a fruit and vegetable placement plate in the fruit and vegetable placement box body. If the road jolts, the third elastic buffer plate can slow down some mechanical force generated by external jolts, so that the mechanical force transmitted to the fruit and vegetable placing plate is lightened or eliminated, the influence of the mechanical force on fruits and vegetables placed on the fruit and vegetable placing plate is lightened, and the quality of the fruits and vegetables is further reduced or avoided from being influenced by collision.

The first buffering component comprises a buffering telescopic component and a buffering dispersing component, one end of the buffering telescopic component is connected to the inner wall of the fresh-keeping box body, and the other end of the buffering telescopic component is connected with the buffering dispersing component. The buffering telescopic component and the buffering dispersing component are matched with each other, so that a double buffering effect can be achieved, the influence of mechanical force generated by road jolt on fruits and vegetables placed on the fruit and vegetable placement plate in the fruit and vegetable placement box body is reduced or slowed down, and the quality of the fruits and vegetables is further reduced or avoided from being influenced by collision of the fruits and vegetables.

The buffer dispersing assembly comprises a first buffer gear and a second buffer gear, and the first buffer gear is in meshed connection with the second buffer gear. The first buffer gear and the second buffer gear are connected between the buffer telescopic assembly and the elastic connecting block through respective gear shafts, and the elastic connecting block is detachably connected with the fruit and vegetable placement assembly. In the fruit and vegetable transportation process, if meeting the road and jolting, the fruit and vegetable placement box can shake, and then can make the fruit and vegetable placement plate shake along with it, and then make the fruit and vegetable placed on the fruit and vegetable placement plate shake along with it and then collide. At this moment, when the box body is placed to fruit vegetables can take place to rock, the mechanical force that rocks the production can alleviate partly through the cushioning effect of buffering flexible subassembly earlier, and remaining mechanical force rethread first buffer gear and second buffer gear's rotation and transmission between them obtain consuming, and then make the mechanical force that the box body was placed to fruit vegetables reduce to very little, is insufficient for making fruit vegetables in it rock and collide, guarantees the quality of fruit vegetables then.

Preferably, the buffering telescopic component comprises a pi-shaped first connecting plate, the first buffering gear and the second buffering gear are respectively movably connected to a main plate at one end of the first connecting plate through different gear shafts, the end parts of two side plates at the other end of the first connecting plate are connected to the inner wall of the fresh-keeping box body, and a first buffering spring is arranged between the two side plates on the first connecting plate.

Specifically, the first connecting plate is made of a transverse plate and two vertical plates vertically and parallelly connected with the transverse plate. The side wall of one side of the transverse plate is rotationally connected with a first rotating shaft (a first gear shaft) and a plurality of second rotating shafts (second gear shafts), and the first rotating shaft (the first gear shaft) is arranged between the second rotating shafts (the second gear shafts). The first buffer gear is movably arranged on the first rotating shaft (the first gear shaft), and the second buffer gear is movably arranged on the second rotating shaft (the second gear shaft).
