Description

Technical Field

[0001] The utility model relates to the technical field of sorting machines, in particular to a fruit sorting machine anti-stacked fruit structure. Background Art

[0002] A sorting machine is a device used for self-sorting, usually used in logistics, fruit, medical and health industries. In the fruit industry, the produced fruit needs to go through a series of reproduction processes from the farmland to the market. The fruit is transported by small fruit trays on the sorting machine conveyor line. The fruit is cleaned, sorted by size and bad products are removed during the transportation process. In particular, some supermarkets and high-end fruit sales have high requirements for the appearance of fruits. Therefore, sorting machines play an important role in fruit sorting.

[0003] During the fruit transportation process, due to the different sizes and quantities of fruits, some fruits are transported in an overlapping manner. The overlapping fruits are poured into the fruit tray together, and fruits are easily overlapped on the fruit tray, thus affecting the subsequent processing and handling of the fruits. To address the above problems, we have launched a fruit sorting machine anti-overlapping structure. Utility Model Content

[0004] The utility model discloses a fruit sorting machine anti-overlapping structure. Part of the fruits are transported in an overlapping manner, and the overlapping fruits are poured into a fruit tray together. Fruits are easily overlapped on the fruit tray, thus affecting the technical problem of subsequent processing and handling of the fruits.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fruit sorting machine anti-overlapping fruit structure comprises a fruit tray support shaft, wherein left and right ends of the fruit tray support shaft are connected to a limiting height mechanism, wherein the limiting height mechanism is used to prevent overlapping fruits from passing through; the limiting height mechanism comprises a first connecting rod slidably connected to the outer surfaces of the left and right ends of the fruit tray support shaft, a sliding groove is provided at the upper end of the first connecting rod, a second connecting rod is slidably connected inside the sliding groove, and the upper ends of two groups of the second connecting rods are fixedly connected to the limiting height rod.

[0007] According to a further technical solution, the left and right ends of the outer surface of the fruit support shaft are rotatably connected to fruit support wheels, and springs are connected between the fruit support wheels.

[0008] By arranging springs between the fruit support wheels, the elastic force of the springs pushes the fruit support wheels to both sides of the fruit support shaft, thereby ensuring that the fruit support wheels are at the edge positions of the fruit support shaft.

[0009] According to a further technical solution, an adjusting bolt is threadedly connected to the upper end of the first connecting rod on a side away from the vertical central axis of the fruit tray support shaft, and the second connecting rod is fixedly connected to the first connecting rod via the adjusting bolt.

[0010] After the second connecting rod slides inside the first connecting rod, the position of the second connecting rod is fixed by the adjusting bolt, thereby achieving height adjustment of the height limiting rod.

[0011] According to a further technical solution, a roller is rotatably connected to the outer surface of the height limiting rod, and a brush is provided on the outer surface of the roller.

[0012] By arranging a brush on the outer surface of the drum, it is convenient to clean the surface when the fruit passes under the height limit rod.

[0013] According to a further technical solution, a threaded hole is provided on a side of the height limiting rod away from the second connecting rod, a screw rod is threadedly connected inside the threaded hole, a nut is fixedly connected between the two groups of the screw rods, and the roller is transmission-connected to the nut via the screw rod.

[0014] The screw is driven to rotate by rotating the nut. Since the threads of the two sets of screw rods rotate in opposite directions on their outer surfaces, the screw rods rotate in the threaded holes, causing the rollers to move inward or outward at the same time.

[0015] Compared with the prior art, it has the following improvements and advantages:

[0016] The fruits overlapping on the upper layer are blocked by the height limiting rod to ensure that the fruits at the lower end pass under the height limiting rod, thereby preventing the overlapping fruits from entering the fruit tray and affecting the subsequent processing of the fruits. At the same time, by loosening the adjusting bolt, the second connecting rod is prompted to slide in the first connecting rod, thereby adjusting the distance between the height limiting rod and the fruit tray wheel to accommodate the passage of fruits of different sizes.

[0017] By rotating the nut, the drive screw rotates, causing the height limit rod and the roller to move inward, and synchronously pulling the second connecting rod and the first connecting rod to move inward. The first connecting rod drives the two sets of fruit support wheels to slide inward on the fruit support shaft, thereby adjusting the distance between the left and right sets of first connecting rods and second connecting rods to ensure that only one fruit passes through, making it convenient for the subsequent processing of the fruit on the fruit support.

[0018] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The utility model discloses a fruit sorting machine anti-stacking fruit structure which is mainly used in the scene where fruits are transported to fruit trays.

[0026] Reference Figure 1 , Figure 3 and Figure 4 , a fruit sorting machine anti-overlapping fruit structure, comprising a fruit support shaft 1, the left and right ends of the fruit support shaft 1 are connected to a limited height mechanism 2, the limited height mechanism 2 is used to prevent overlapping fruits from passing; the limited height mechanism 2 comprises a first connecting rod 201 slidably connected to the outer surfaces of the left and right ends of the fruit support shaft 1, a slide groove 202 is provided at the upper end of the first connecting rod 201, a second connecting rod 203 is slidably connected inside the slide groove 202, a limited height rod 204 is fixedly connected to the upper end between the two groups of second connecting rods 203, a roller 7 is rotatably connected to the outer surface of the limited height rod 204, a brush 8 is arranged on the outer surface of the roller 7, a fruit support wheel 3 is rotatably connected to the left and right ends of the outer surface of the fruit support shaft 1, an adjusting bolt 5 is threadedly connected to the upper end of the first connecting rod 201 away from the vertical central axis of the fruit support shaft 1, and the second connecting rod 203 is fixedly connected to the first connecting rod 201 through the adjusting bolt 5;

[0027] In this embodiment, when the fruits are introduced from the conveyor belt to the fruit trays, some of the fruits on the conveyor belt are transported in an overlapping manner. When the overlapping fruits enter the upper end of the fruit tray wheel 3, the fruits overlapping on the upper layer are blocked by the height limiting rod 204 to ensure that the fruits at the lower end pass under the height limiting rod 204 and enter the position between the two groups of fruit trays. The fruits overlapping on the upper end are blocked on the conveyor belt, thereby preventing the overlapping fruits from entering the fruit trays together and affecting the subsequent processing of the fruits. Since the fruit tray wheel 3 is rotatably connected to the fruit tray support shaft 1, the fruits entering above the fruit tray wheel 3 rotate with the fruit tray wheel 3 under the action of the conveying transmission, and the dirt on the outer surface of the fruit is cleaned by the brush 8 on the outer side of the drum 7. When other fruits are transported in fruit trays, the size of the fruit changes, and the height of the fruit is higher than the height of the height limiting rod 204, and it cannot pass through the lower end of the height limiting rod 204. At this time, the adjusting bolt 5 is loosened by rotating it, and the second connecting rod 203 is loose inside the first connecting rod 201. At this time, the second connecting rod 203 is pulled upward to drive the height limiting rod 204 to move upward, and the height is adjusted according to the maximum diameter of the fruit. Then the adjusting bolt 5 is rotated and tightened to fix the second connecting rod 203 inside the first connecting rod 201. At this time, the fruit can pass through the height limiting rod 204. Therefore, by adjusting the distance between the height limiting rod 204 and the fruit supporting wheel 3, it can adapt to the passage of fruits of different sizes.

[0028] Reference Figure 1 and Figure 3 In a preferred embodiment, a threaded hole 205 is provided on one side of the height limiting rod 204 away from the second connecting rod 203, a screw rod 206 is threadedly connected inside the threaded hole 205, a nut 6 is fixedly connected between the two sets of screw rods 206, the roller 7 is transmission-connected to the nut 6 through the screw rod 206, and a spring 4 is connected between the fruit supporting wheels 3;

[0029] In this embodiment, when the fruit diameter is small, the height reaches the limit adjustment, and the width does not change. The fruits can easily enter the top of the fruit tray side by side and overlap. At this time, the transmission screw 206 is rotated by rotating the nut 6, prompting the height limit rod 204 and the roller 7 to move inward. The height limit rod 204 pulls the second connecting rod 203 and the first connecting rod 201 to move inward. During the movement of the first connecting rod 201, the fruit supporting wheel 3 is squeezed, prompting the two groups of fruit supporting wheels 3 to slide inward on the fruit supporting shaft 1, and the spring 4 is contracted to ensure that the two groups of fruit supporting wheels 3 are pushed to the left and right ends of the fruit supporting shaft 1 to form symmetry. After adjustment according to the maximum diameter of the fruit, the rotation of the nut 6 is stopped. At this time, the side-by-side fruits are blocked by the left and right first connecting rods 201 and the second connecting rod 203 to ensure that only one fruit passes.

[0030] Working principle: When in use, when the fruits are introduced from the conveyor belt to the fruit tray, some of the fruits on the conveyor belt are conveyed in an overlapping manner. When the overlapping fruits enter the upper end of the fruit tray wheel 3, the fruits overlapping on the upper layer are blocked by the height limiting rod 204 to ensure that the fruits at the lower end pass under the height limiting rod 204 and enter the position between the two groups of fruit trays. The overlapping fruits at the upper end are blocked on the conveyor belt, thereby preventing the overlapping fruits from entering the fruit tray together and affecting the subsequent processing of the fruits. Since the fruit tray wheel 3 is rotatably connected to the fruit tray support shaft 1, the fruits entering above the fruit tray wheel 3 rotate with the fruit tray wheel 3 under the action of the conveying transmission, and the dirt on the outer surface of the fruit is cleaned by the brush 8 on the outer side of the drum 7. When other fruits are being transported in fruit trays, the size of the fruit changes, and the height of the fruit is higher than the height of the height limiting rod 204, and it cannot pass through the lower end of the height limiting rod 204. At this time, the adjusting bolt 5 is rotated to loosen it, and the second connecting rod 203 is loose inside the first connecting rod 201. At this time, the second connecting rod 203 is pulled upward to drive the height limiting rod 204 to move upward, and the height is adjusted according to the maximum diameter of the fruit. Then the adjusting bolt 5 is rotated and tightened to fix the second connecting rod 203 inside the first connecting rod 201. At this time, the fruit can pass through the height limiting rod 204. Therefore, by adjusting the distance between the height limiting rod 204 and the fruit supporting wheel 3, it can adapt to the passage of fruits of different sizes.
