[0042] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application, and the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0043] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0048] The precooling box is provided with a plurality of inclined first partitions 2111 and second partitions 2112, which are arranged at intervals and in opposite directions. The first partitions 2111 and second partitions 2112 divide the precooling space of the precooling box into a plurality of layers of subspaces, one end of the first partition 2111 is provided with a first blanking port 2113 for connecting two adjacent subspaces, and the other end of the second partition 2112 (i.e., the end away from the first blanking port 2113) is provided with a second blanking port 2114 for connecting two adjacent subspaces.

[0050] The intelligent pre-cooling and sorting device for fruits and vegetables provided in the present application is suitable for pre-cooling treatment of fruits and vegetables that are approximately round (such as oranges, tangerines, apples and tomatoes, etc.), and the distance between the first partition 2111 and the second partition 2112 (i.e., the height of the subspace) is designed according to the variety of pre-cooled fruits and vegetables, so that the subspace only allows a single layer of materials to pass through.

[0051] The lower end of the precooling box is provided with a discharge port 2116, and a discharge control mechanism is provided at the discharge port 2116.

Exemplarily, the front ends of the first partition plate 2111 and the second partition plate 2112 are fixedly connected to the front side plate by welding, and the rear ends of the first partition plate 2111 and the second partition plate 2112 are fixedly connected to the rear side plate by welding.

The first transfer cylinder 213 is a cylindrical structure and is hollow inside. A first notch 2131 is provided on the cylindrical side wall of the first transfer cylinder 213, and materials can enter the first transfer cylinder 213 through the first notch 2131. The first transfer cylinder 213 has two working positions. When the first transfer cylinder 213 is in the first working position, as shown in FIG. Figure 6 As shown, the first notch 2131 of the first transfer cylinder 213 faces the material, and the material can enter the first transfer cylinder 213 through the first notch 2131; when the first transfer cylinder 213 is in the second working position, the first notch 2131 of the first transfer cylinder 213 faces downward, and the material in the first transfer cylinder 213 can be moved out through the first notch 2131.

[0059] Furthermore, if Fig.10 As shown, a receiving trough 216 is provided at the bottom of the precooling box, which is located just below the discharge port 2116. The receiving trough 216 is parallel to the projection of the first transfer cylinder 213 in the horizontal plane, and the receiving trough 216 is connected to the precooling space of the precooling box through the discharge port 2116. The receiving trough 216 includes a web and wing plates located at the left and right ends of the web, and the upper ends of the wing plates are fixedly connected to the bottom plate of the main shell 211 by welding. Exemplarily, the distance between the two wing plates is equal to the width of the discharge port 2116 (that is, the dimension of the discharge port 2116 along the left and right directions), and the inner side surfaces of the two wing plates are flush with the left and right sides of the discharge port 2116, respectively. The web of the receiving trough 216 extends along the extension direction of the receiving trough 216 (according to the Figure 1The coordinate system shown is in the front-to-back direction) and the lower end extends to the outside of the precooling box. When the first transfer cylinder 213 is in the second working position, the material in the first transfer cylinder 213 will fall into the material receiving groove 216 through the first notch 2131, and slide out of the bottom of the precooling box through the material receiving groove 216.

The air guide hood 2122 is a conical structure with the large end facing the end plate 2121, and the large end of the air guide hood 2122 is fixedly connected to the end plate 2121 by welding. The end plate 2121 and the air guide hood 2122 together form a uniform flow chamber, and the small end of the air guide hood 2122 is provided with an air duct 2123 connected to the uniform flow chamber, and the end plate 2121 is provided with air holes 21211 for connecting the uniform flow chamber and the pre-cooling space.

The second notch 2171 is provided on the second cylinder body. Exemplarily, the second notch 2171 penetrates the second cylinder body along the axial direction.

[0066] Preferably, the interior of the second transfer cylinder 217 can only accommodate one row of materials, that is, the materials entering the second transfer cylinder 217 can only be arranged in a two-line shape along the bearing, and two materials cannot be accommodated in the same cross section at the same time.

[0067] Furthermore, the first transfer cylinder 213 and the second transfer cylinder 217 are connected via a second transmission mechanism 218 , and the second transfer cylinder 217 can rotate synchronously with the first transfer cylinder 213 at the same angular velocity via the second transmission mechanism 218 .

A plurality of inclined material guide troughs 3 are provided on the base frame 1 below the sorting port 2161, and the plurality of material guide troughs 3 are arranged in a line along the extension direction of the receiving trough 216. Since the width of the sorting port 2161 gradually increases in the direction away from the discharge port 2116, materials of different sizes fall at different positions in the sorting port 2161, and the pre-cooled materials can be graded accordingly. That is, Figure 5 As shown, when the material flows from the higher end to the lower end along the material receiving trough 216, the material can fall through the sorting port 2161 and enter the material guide trough 3 of the corresponding grade.

[0073] Furthermore, a first baffle 2162 is provided at a lower end of the material receiving trough 216. In this way, it is possible to prevent the unsuccessfully sorted materials from falling.

[0074] Furthermore, a pressure sensor (not shown in the figure) is provided on the first baffle 2162. When the material is not successfully sorted, it will continue to move along the receiving trough 216 until it abuts against the first baffle 2162. At this time, the pressure sensor (not shown in the figure) located on the first baffle 2162 is triggered. After the controller receives the signal from the pressure sensor (not shown in the figure), it controls the alarm to sound, thereby reminding the staff that the material has not been successfully sorted and needs to be manually removed to avoid affecting the subsequent sorting work.

[0075] Furthermore, a second baffle 2163 is provided at a higher end of the receiving trough 216 .
