Detailed Description
The present application is described in further detail below with reference to figures 1-6.
The embodiment of the application discloses fruit vegetables conveying mechanism is used in fruit vegetables separation.
Example 1
Referring to fig. 1, the fruit and vegetable conveying mechanism for sorting fruits and vegetables includes a base 1, a tray 2 and a connecting mechanism 3.
The lower surface of the base 1 is provided with a mounting groove 11, and the mounting groove 11 is used for being sleeved on a conveying transmission chain 4 of the fruit and vegetable sorting machine, so that the base 1 moves along with the conveying transmission chain 4; the tray 2 is arranged above the base 1, and a groove for placing fruits and vegetables is formed in the upper surface of the tray 2; tray 2 level and perpendicular fruit vegetables are selected separately with fruit vegetables conveying mechanism direction of delivery's both ends all integrated into one piece have weighing arm 21 and upset arm 22, and in this embodiment, upset arm 22 is located weighing arm 21's below.
Meanwhile, the tray 2 and the base 1 are movably connected through the connecting mechanism 3, so that the fruits and vegetables in the tray 2 are weighed and overturned for sorting.
Referring to fig. 1 and 2, the connecting mechanism 3 includes a fixing member 31 and a clip member 32.
The fixing member 31 and the base 1 are integrally formed by injection molding, and the fixing member 31 is plate-shaped and has two side-by-side parts. The fixing piece 31 is perpendicular to the conveying direction of the fruit and vegetable conveying mechanism for fruit and vegetable sorting, the fixing piece 31 is provided with a sliding groove 311 and an overturning groove 312, and the groove depth directions of the sliding groove 311 and the overturning groove 312 are both parallel to the conveying direction of the fruit and vegetable conveying mechanism for fruit and vegetable sorting; and the side walls of the sliding slots 311 on the two fixing pieces 31 are flush. The sliding groove 311 extends vertically; the overturning groove 312 is positioned above the sliding groove 311 and communicated with the sliding groove 311; the turning groove 312 is fan-shaped, and the center of the fan-shaped circle is located in the sliding groove 311.
The clips 32 are integrally injection-molded with the tray 2, and at the same time, two clips 32 are provided corresponding to the two fixing members 31, and the two clips 32 are symmetrically arranged about the center of the tray 2. The clamping piece 32 is used for being embedded into the sliding groove 311 and the overturning groove 312; in this embodiment, in order to facilitate the clip 32 to be embedded into the sliding groove 311 and the turning groove 312, the tray 2 is further integrally formed with two ear plates 23, the two ear plates 23 are arranged side by side, the two ear plates 23 are both located between the two fixing members 31, meanwhile, the ear plates 23 are parallel to the fixing members 31, and the two clips 32 are respectively arranged on one side of the two ear plates 23 opposite to each other.
Referring to fig. 2 and 3, the clip 32 includes two pins 321 arranged side by side, and when the lower pin 321 is located at the bottom of the sliding slot 311, the axis of the upper pin 321 coincides with the center of the turning slot 312.
