[0034] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0035] like Figure 1 The figure shows a schematic diagram of the structure of a double-station double-carriage high-speed seeding and sorting machine of the present invention, which includes a main sorting frame 1, a sorting slide 2, a sorting plate 3, a sorting slot 4, a transverse sorting component and a longitudinal sorting component. The main sorting frame 1 is welded from aluminum profiles and is mainly used to fix and install the transverse sorting component and the longitudinal sorting component.

[0036] like Figure 2 As shown, the sorting slides 2 are tilted and fixed on both sides of the main sorting frame 1, and are used to transfer the goods sorted by the transverse sorting assembly to the sorting bags on both sides. By arranging the sorting slides 2 on both sides of the main sorting frame 1, the transverse sorting trolley is arranged between the sorting slides 2, and the two sorting directions of the transverse sorting trolley correspond to the sorting slides 2 on both sides respectively, the goods can be sorted to both sides, thereby improving the sorting efficiency of the goods.

[0037] By providing an inclined sorting slide 2, the goods on the horizontal sorting trolley are sorted onto the sorting slide 2, and slide down into the sorting bag under the action of their own gravity, thereby avoiding the goods from being blocked at the sorting grid of the sorting slide 2, thereby affecting the sorting efficiency.

[0038] The sorting slide plate 2 is provided with multiple layers at intervals in the vertical direction, which is used to match the multiple layers of horizontal sorting components in the vertical direction, thereby improving the sorting efficiency while making the overall structure more compact and occupying a smaller area.

[0039] The sorting plates 3 are fixed at intervals on the outside of the sorting slide plate 2, and sorting slots 4 are formed between two adjacent sorting plates 3. The goods on the horizontal sorting cart are sorted into the corresponding sorting slots 4 on the sorting slide plate 2, and then sorted into the corresponding sorting bags along the sorting slots 4 under the action of their own gravity.

[0040] like Figure 2 As shown, the sorting plate 3 is in a "V" shape, and the sharp corner of the "V"-shaped sorting plate 3 is close to the main sorting frame 1, so the sorting slot 4 decreases from the inside to the outside of the main sorting frame 1, so that the sorting plates 3 on both sides will play a guiding role for the goods when sorting the goods.

[0041] Since the sorting plate 3 is in a "V" shape, when the goods on the horizontal sorting trolley are sorted into the corresponding sorting slots 4 on the sorting slide plate 2, the goods will not be stuck on the sorting plate 3, thereby avoiding goods jam.

[0042] There are multiple groups of horizontal sorting components spaced apart in the vertical direction, which cooperate with the sorting slide 2 outside the main sorting frame 1 to sort the goods into the corresponding sorting slots 4 on the sorting slide 2. Figure 9-12 As shown, each set of transverse sorting components includes a transverse mounting frame 26, a main driving wheel 27, an auxiliary driving wheel 28, a driving belt 29, a pressing plate 30, an upper pressing roller 31, a lower pressing roller 32, a fourth contact wheel 33, a fifth contact wheel 34 and a rubber pad 35. The transverse mounting frame 26 is fixed to the inner side of the main sorting frame 1 and is located on the inner side of the sorting slide 2. The transverse mounting frame 26 extends along the length direction of the main sorting frame 1, and the length of the transverse mounting frame 26 is the same as that of the main sorting frame 1, ensuring that the transverse sorting trolley can deliver the goods to each sorting slot 4 to avoid a blind spot in sorting.

[0043] like Fig. 9 As shown, two transverse sorting trolleys are slidably arranged on the transverse mounting frame 26, and each transverse sorting trolley is used for sorting in half of the area of ​​the transverse mounting frame 26, shortening the sorting path, thereby improving the sorting efficiency. Therefore, two sets of driving mechanisms are arranged on the transverse mounting frame 26, which are used to drive the transverse sorting trolleys to move respectively (one transverse sorting trolley is connected to one set of driving mechanisms, and the other transverse sorting trolley is connected to the other set of driving mechanisms, and the movements of the two do not interfere with each other).

[0044] The driving mechanism of the transverse sorting component includes a main driving wheel 27, an auxiliary driving wheel 28, a driving belt 29, a pressure plate 30, an upper pressure roller 31 and a lower pressure roller 32. The main driving wheel 27 is connected to the servo motor and is arranged on one side of the transverse mounting frame 26. The auxiliary driving wheel 28 is rotatably mounted on the other side of the transverse mounting frame 26. The driving belt 29 is wound around the main driving wheel 27 and the auxiliary driving wheel 28. The main driving wheel 27 is driven to rotate by the servo motor, and then the auxiliary driving wheel 28 is driven to rotate.

[0045] The pressing plate 30 is fixed on the inner side of the horizontal mounting frame 26, and the upper pressing roller 31 and the lower pressing roller 32 are rotatably arranged on one side of the pressing plate 30 (two roller shafts are fixed on the side of the pressing plate 30 close to the driving belt 29, and the upper pressing roller 31 and the lower pressing roller 32 are respectively sleeved on the roller shafts). The upper pressing roller 31 presses against the outer side of the driving belt 29, and the lower pressing roller 32 presses against the inner side of the driving belt 29. The upper pressing roller 31 and the lower pressing roller 32 are arranged to press the driving belt 29 during the rotation process, thereby improving the sliding stability of the horizontal sorting trolley.

[0046] like Fig.12 As shown, the bottom of the horizontal sorting trolley is rotatably mounted with a fourth wheel 33 and a fifth wheel 34, and the horizontal mounting frame 26 is in a "[" shape. The "["-shaped horizontal mounting frame 26 is composed of two A fixing plates arranged opposite to each other and a B fixing plate integrally connected between the two A fixing plates. The fourth wheel 33 abuts against the inner side walls of the two A fixing plates, and the fifth wheel 34 abuts against the inner side walls of the B fixing plate. When the horizontal sorting trolley slides, the fourth wheel 33 and the fifth wheel 34 will rotate against the "["-shaped horizontal mounting frame 26, thereby improving the stability of the horizontal sorting trolley when sliding.

[0047] The rubber pad 35 is fixed to the inner side wall of the transverse sorting trolley to prevent the two transverse sorting trolleys from colliding when moving inward.

[0048] One of the transverse sorting trolleys is connected to the driving belt 29 of one set of driving mechanisms, and the other transverse sorting trolley is connected to the driving belt 29 of the other set of driving mechanisms, and the two do not interfere with each other. Driven by the driving mechanism, each transverse sorting trolley reciprocates in the half area of ​​the transverse mounting frame 26, thereby sorting the goods into the sorting slots 4 corresponding to the sorting slide 2.

[0049] like Figure 3-5 As shown in FIG. 1 , it is a schematic diagram of the structure of the longitudinal sorting component. The longitudinal sorting component is arranged on one side of the transverse sorting component and is used to lift the goods to each layer of the transverse sorting component. Figure 3 As shown, there are two groups of longitudinal sorting components which are arranged opposite to each other so as to match the two transverse sorting carts on each layer of transverse sorting components. Each group of longitudinal sorting components includes a lifting frame 5, a driving mechanism, a longitudinal mounting frame 13, a limiting mechanism and a longitudinal sorting cart.

[0050] The lifting frame 5 is welded from aluminum profiles and fixed on the outside of the main sorting frame 1. The height of the lifting frame 5 is the same as that of the main sorting frame 1, so as to ensure that the goods can be lifted to each layer of the horizontal sorting assembly to avoid the occurrence of a blind spot in sorting. The driving mechanism is arranged on the outside of the lifting frame 5, and the longitudinal mounting frame 13 is connected to the driving mechanism, and the longitudinal mounting frame 13 is driven by the driving mechanism to perform lifting and lowering movements in the vertical direction. The longitudinal sorting trolley is fixed on the longitudinal mounting frame 13, and cooperates with the horizontal sorting trolley on each layer of the horizontal sorting assembly to lift the goods to the horizontal sorting trolley of each layer of the horizontal sorting assembly, thereby completing the sorting of the goods.

[0051] The driving mechanism of the longitudinal sorting assembly includes a lifting motor 6, a main synchronous wheel 7, an auxiliary synchronous wheel 8, a synchronous belt 9, a lifting driving wheel 10, a lifting driven wheel 11 and a lifting belt 12. Figure 4 As shown, the lifting motor 6 is fixed on the top of the lifting frame 5, the main synchronous wheel 7 is connected to the lifting motor 6, and the main synchronous wheel 7 is driven to rotate by the lifting motor 6. The first roller shaft passes through the lifting frame 5 and is connected to the lifting frame 5 through a bearing, the auxiliary synchronous wheel 8 is fixed to the end of the first roller shaft by a key, and the synchronous belt 9 is wound around the main synchronous wheel 7 and the auxiliary synchronous wheel 8. The torque is transmitted to the auxiliary synchronous wheel 8 through the synchronous belt 9, and then the first roller shaft is driven to rotate (the lifting motor 6 and the first roller shaft are transitionally connected by setting the main synchronous wheel 7, the auxiliary synchronous wheel 8 and the synchronous belt 9, instead of directly connecting the lifting motor 6 and the first roller shaft, in order to reduce the overall space volume).

[0052] like Figure 5 As shown, the lifting driving wheel 10 is fixed on the first roller shaft, the second roller shaft passes through the bottom of the lifting frame 5 and is connected to the lifting frame 5 through a bearing, and the lifting driven wheel 11 is fixed on the second roller shaft. The lifting belt 12 is wound around the lifting driving wheel 10 and the lifting driven wheel 11, and the longitudinal mounting frame 13 is connected to the lifting belt 12, and the lifting belt 12 drives the longitudinal mounting frame 13 to perform lifting and lowering movements.

[0053] The longitudinal sorting trolley is fixed on the longitudinal mounting frame 13, and cooperates with the transverse sorting trolley on each layer of the transverse sorting assembly to lift the goods to the transverse sorting trolley on each layer of the transverse sorting assembly, thereby completing the sorting of the goods. Figure 8 As shown, the longitudinal sorting trolley includes a partition 17, a main roller 18, an auxiliary roller 19, a conveyor belt 20, a pad 21, a material blocking plate 22, a chute 23, a limit plate 24 and a push rod 25. There are two partitions 17 and they are arranged at intervals. The main roller 18 is rotatably arranged on one side of the partition 17. A driving motor is fixed on the outer side of the partition 17 to drive the main roller 18 to rotate.

[0054] The auxiliary roller 19 is adjustable and arranged on the other side of the partition 17. The conveyor belt 20 is wound around the main roller 18 and the auxiliary roller 19. The conveyor belt 20 is driven by the driving motor to complete the sorting of goods. The conveyor belt 20 is tensioned by setting the adjustable auxiliary roller 19 to avoid deformation and elongation of the conveyor belt 20 caused by frequent sorting of goods.

[0055] There are two baffle plates 22, which are fixed at intervals on the top plate of the partition 17 to prevent the goods from falling from both sides when sorting the goods. The pad 21 is fixed between the two partitions 17 and is used to support the conveyor belt 20 to prevent the conveyor belt 20 from sinking downward.

[0056] The slide groove 23 is horizontally opened on one side of the partition 17, the limit plate 24 is fixed on the outer side of the partition 17, the push rod 25 passes through the limit plate 24, and the limit plate 24 is provided with a through hole matched with the push rod 25 to limit the moving push rod 25. The push cylinder is fixed on the outer side of the partition 17 and connected to the push rod 25, and the push cylinder is not shown in the figure.

[0057] The roller shaft is fixed on the push rod 25, and the push rod 25 drives the roller shaft to move in the chute 23. The auxiliary roller 19 is set on the roller shaft through the bearing sleeve, which satisfies the tension of the conveyor belt 20 while ensuring that the auxiliary roller 19 can rotate normally.

[0058] like Figure 6 , 7 As shown, the limiting mechanism is arranged between the longitudinal mounting frame 13 and the lifting frame 5 to improve the stability of the lifting movement of the longitudinal mounting frame 13. The limiting mechanism includes a first stopper 14, a second stopper 15 and a third stopper 16 rotatably mounted on the longitudinal mounting frame 13 near the lifting frame 5. The lifting frame 5 is in a "[" shape, and the "["-shaped lifting frame 5 is composed of two C fixing plates arranged opposite to each other and a D fixing plate integrally connected between the two C fixing plates.

[0059] The third wheel 16 abuts against the inner side walls of the two C fixed plates, the second wheel 15 abuts against the inner side wall of the D fixed plate, and the first wheel 14 abuts against the outer side wall of one of the C fixed plates. When the longitudinal sorting trolley slides, the first wheel 14, the second wheel 15 and the third wheel 16 will rotate against the "["-shaped lifting frame 5, thereby improving the stability of the longitudinal sorting trolley when sliding.

[0060] The sorting principle of the double-station double-carriage high-speed sowing and sorting machine of the present invention is as follows:

[0061] The goods are transported to the longitudinal sorting trolley, which moves up and down in the longitudinal direction, so as to transfer the goods to the transverse sorting trolley of each transverse sorting rack, and the transverse sorting trolley moves and sorts the goods into each sorting slot 4. The whole sorting process has a high degree of automation. By setting up a double-station longitudinal sorting trolley and a transverse sorting trolley, the sorting efficiency of the goods is greatly improved, the manpower is greatly reduced, the labor intensity of the workers is reduced, and it is conducive to realizing the automation of extracting and transporting goods, and has broad promotion prospects.
