[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment one: please refer to Figures 1-6 The utility model provides the following technical scheme: a flexible protection type delivery device for fruit screening, including machine table 1, both sides of machine table 1 are provided with conveying roller 2 through support frame, and the outer side of two conveying rollers 2 is provided with a plurality of conveying belts 3 in transmission, the left side of machine table 1 is connected with guide table 4, the top surface of machine table 1 is inclined downward from back to front, and the top of each conveying belt 3 is fixedly connected with baffle 5, and a plurality of through slots are formed in the bottom of baffle 5, the conveying platform 6 that is evenly distributed is connected on the conveying belt 3, and the gravity screening mechanism 7 for fruit screening is arranged on the conveying platform 6, the outer side of conveying platform 6 and gravity screening mechanism 7 is covered with elastic cover cloth 8, and the inside top of elastic cover cloth 8 is sewn with flexible pad 9, and the top of machine table 1 is provided with receiving net 16 arranged in matrix at the front end of each conveying belt 3.

[0026] When the device is in operation, the fruits are guided to the conveying platform 6 of each conveying belt 3 via the guide table 4, and the elastic cover cloth 8 and the flexible pad 9 outside the conveying platform 6 can effectively protect the fruits that fall from the guide table 4. Then, the gravity screening mechanism 7 performs weight classification screening on the fruits, so that the fruits are poured forward at different positions, and the receiving net 16 receives the fruits to make them continue to roll forward and fall gently onto the machine table 1, i.e. to perform secondary flexible protection on the fruits. The fruits on the machine table 1 continue to roll forward and pass through the through slot of the baffle 5 in turn, and finally fall into the collecting bag placed at the front end of the machine table 1 (not shown in the figure). During the whole screening and delivery process, the fruits can be effectively protected by the elastic cover cloth 8, the flexible pad 9 and the receiving net 16 when they are transferred on the guide table 4, the conveying platform 6 and the machine table 1, so as to avoid the problem that the good product rate is affected due to the broken fruits.

[0027] The top surface of the guide table 4 is inclined downward from left to right, and a plurality of narrowing channels are arranged at the top end of the guide table 4. The narrowing port of each group of narrowing channels corresponds to the above of each conveying belt 3. By the guide table 4 and the narrowing channels at the top end thereof, the fruits are poured from the left opening of the guide table 4, and the fruits are guided by the narrowing channels to accurately roll right to the conveying platform 6 above each conveying belt 3, so as to facilitate the subsequent screening of the gravity screening mechanism 7. The gravity screening mechanism 7 includes a turnover plate 10 rotating at the top front end of the conveying platform 6, and the flexible pad 9 is located at the top of the turnover plate 10. The bottom of the turnover plate 10 is fixedly installed with a common magnet 11, and the top inside of the conveying platform 6 is fixedly installed with an electromagnet 12. When the electromagnet 12 is electrified, it repels the common magnet 11. The end surface of the baffle 5 is fixedly installed with evenly distributed inductors 13. When the conveying platform 6 above the conveying belt 3 passes each inductor 13, the current input to the electromagnet 12 inside the conveying platform 6 is increased by one level. When the conveying platform 6 turns to the below of the conveying belt 3, the current input to the corresponding electromagnet 12 is zero. When the fruits are conveyed on the conveying platform 6 by the conveying belt 3, the current input to the electromagnet 12 is increased by passing each inductor 13, and the repulsive force between the electromagnet 12 and the common magnet 11 is increased. When the repulsive force is greater than the weight of the fruits and the turnover plate 10, the turnover plate 10 is pushed to rotate to pour the fruits thereon. In this way, the fruits in different weight intervals can be poured at different transmission positions, i.e. the weight classification screening of the fruits is realized.

The downward concave structure of the elastic cover cloth 8 and the flexible pad 9 makes the conveying platform 6 more stable when supporting the fruits falling from the guide table 4. The pleated structure of the elastic cover cloth 8 leaves a stretching space for the turning of the turning plate 10. In addition, the outer edge of the receiving net 16 is sewn with a sleeve rope 15. The top of the machine table 1 is fixedly connected with four support rods 14 corresponding to each weight interval.

The front ends of the two groups of support rods 14 are respectively provided with clamping grooves on the top. The sleeve rope 15 is sleeved on the outside of the four clamping grooves. The support rod 14 and the sleeve rope 15 can stably install the receiving net 16 and make it inclined downward from back to front. In this way, the fruits falling from the conveying platform 6 can be well received and make them fall gently on the table surface of the machine table 1 and continue to roll out of the material, thereby further ensuring the flexible protection of the fruits.

[0029] In addition, the top center of the elastic cover cloth 8 and the flexible pad 9 is designed as a downward concave structure, and the elastic cover cloth 8 is located at the turning end of the turning plate 10 and is formed as a pleated structure. The downward concave structure of the elastic cover cloth 8 and the flexible pad 9 makes the conveying platform 6 more stable when supporting the fruits falling from the guide table 4. The pleated structure of the elastic cover cloth 8 leaves a stretching space for the turning of the turning plate 10. In addition, the outer edge of the receiving net 16 is sewn with a sleeve rope 15. The top of the machine table 1 is fixedly connected with four support rods 14 corresponding to each weight interval.

The front ends of the two groups of support rods 14 are respectively provided with clamping grooves on the top. The sleeve rope 15 is sleeved on the outside of the four clamping grooves. The support rod 14 and the sleeve rope 15 can stably install the receiving net 16 and make it inclined downward from back to front. In this way, the fruits falling from the conveying platform 6 can be well received and make them fall gently on the table surface of the machine table 1 and continue to roll out of the material, thereby further ensuring the flexible protection of the fruits.

[0030] In addition, the top center of the elastic cover cloth 8 and the flexible pad 9 is designed as a downward concave structure, and the elastic cover cloth 8 is located at the turning end of the turning plate 10 and is formed as a pleated structure.
