[0014] A potato bagging and unloading mechanism includes an aggregate bin 1, an aggregate conveying chain 2, a tonne bag filling chain 4, a tonne bag mouth support 6 and a discharge platform 7; the aggregate bin 1 and the aggregate conveying chain 2 arranged below it are used for conveying and intermittently storing potatoes, the aggregate conveying chain 2 feeds the tonne bag through the tonne bag filling chain 4, a tonne bag filling chain 4 is arranged between the aggregate conveying chain 2 and the discharge platform 7 to reduce the transfer height of the potatoes and avoid damage to the potatoes, the tonne bag is hung open at the outlet of the tonne bag filling chain 4 through the tonne bag mouth support 6 and supported by the discharge platform 7, and the discharge platform 7 cooperates with the sensor 5 installed above the tonne bag to adjust the height difference between the aggregate conveying chain 2 and the potatoes in the tonne bag. The sensor 5 is installed on the aggregate conveying chain 2.

[0015] The sensor 5 always identifies the height of the potatoes in the tonne bag, keeping the tonne bag filling chain 4 at a constant distance from the potatoes and reducing damage to the potatoes.

[0016] In this way, only manual bag hanging is required.

[0017] The aggregate bin 1 is surrounded by a steel plate on the outer wall, and both ends of the steel plate are bent inward at the rear side to form a reduced-diameter discharge port 11 therebetween. The reduced-diameter discharge port 11 guides the potatoes, enabling the potatoes to be centrally transported to the tonne bag filling chain 4, and also plays a role in plugging during the storage operation of the aggregate bin 1.

[0018] The discharging platform 7 includes a platform bottom plate 71, a discharging oil cylinder 73, a guide rail mechanism 74, a lifting oil cylinder 76, a platform frame 77, a lifting mechanism 78 and a bottom plate frame 79; the platform bottom plate 71 is rotatably installed on the bottom plate frame 79, and the discharging oil cylinder 73 installed between the bottom plate frame 79 and the platform bottom plate 71 drives the platform bottom plate 71 to rotate downward to complete the discharging operation. The bottom plate frame 79 is slidably installed on the platform frame 77 through the guide rail mechanism 74. The lifting oil cylinder 76 installed on the platform frame 77 drives the lifting mechanism 78 to lift, and the lifting mechanism 78 drives the platform bottom plate 71 and the ton bags thereon to lift through the bottom plate frame 79.

[0019] The lifting mechanism 78 includes a lifting frame 781, a lifting sprocket 782 and a lifting chain 783; the lifting oil cylinder 76 drives the lifting frame 781 to lift, the lifting sprocket 782 is installed on the lifting frame 781, and the lifting sprocket 782 pulls the bottom plate frame 79 through the lifting chain 783.

[0020] The guide rail mechanism 74 includes two platform guide rails 741 and two roller assemblies 742; roller assemblies 742 are installed at both the front and rear ends of the bottom plate frame 79. The two platform guide rails 741 are channel-shaped tracks and are relatively vertically arranged on both the front and rear sides of the platform bottom plate 71, facilitating the up and down movement of the bottom plate frame 79 along the platform guide rails 741 through the roller assemblies 742 inserted into the platform guide rails 741.

[0021] A plurality of discharging roller wheels 72 are installed on the platform bottom plate 71 along the advancing direction of the ton bags, and each discharging roller wheel 72 is made of rubber material. To protect the potato skin.

[0022] The discharging roller wheels 72 are all built in the long grooves formed on the platform bottom plate 71.

[0023] A folding oil cylinder 75 is installed between the bottom plate frame 79 and the platform frame 77, which is used for the upward folding and downward unfolding of the platform bottom plate 71.

[0024] The platform frame 77 of the discharging platform 7 is rotatably installed on the frame connecting arm 9, and the slewing oil cylinder 10 installed between the frame connecting arm 9 and the platform frame 77 is used to push the platform frame 77 to slewing to realize the folding and unfolding of the discharging platform 7.

[0025] The ton bag filling chain 4 is slidably arranged on the aggregate box connecting frame 12 below the aggregate and carrier chain 2, and a push-pull oil cylinder 3 is installed between the ton bag filling chain 4 and the aggregate box connecting frame 12, which is used to push and pull the ton bag filling chain 4 to extend and retract on the aggregate box connecting frame 12.

[0026] This loading and unloading mechanism can be folded. When folding, the push-pull oil cylinder 3 pulls the ton bag filling chain 4 to retract below the aggregate carrier chain 2. After the folding oil cylinder 75 drives the platform bottom plate 71 to fold upward, the slewing oil cylinder 10 pushes the entire discharging platform 7 to rotate towards the aggregate bin 1, thus completing the folding operation.

[0027] The ton bag mouth support 6 includes two long shafts 61 and multiple hooks 62; the two long shafts 61 are installed on both sides of the ton bag filling chain 4 through bearings 63, and multiple arc-shaped hooks 62 are provided on each long shaft 61.

[0028] Each hook 62 is installed on an arc-shaped plate 65. Each arc-shaped plate 65 is provided with an arc-shaped groove. A kit 64 with an extended frame plate is installed on the long shaft 61. The arc-shaped plate 65 is installed on the extended frame plate through a bolt-nut assembly, enabling the hook 62 to adjust the angle and position installed on the long shaft 61.

[0029] Rotate the long shaft 61, the hook 62 rotates inward, and the ton bag can be removed.

[0030] A foot pedal 8 is provided at the end of the platform bottom plate 71 away from the aggregate bin 1. The foot pedal 8 is rotatably installed on an extension rod, and the extension rod is rotatably installed on the platform frame 77.

[0031] Both the aggregate carrier chain 2 and the ton bag filling chain 4 are driven by a hydraulic motor driving a double-row sprocket.

[0032] The basic functions of this potato bag loading and unloading mechanism are to store, convey, bag, and unload the harvested potato tubers.

[0033] According to the operation sequence, its working principle is as follows:

[0034] The potato tubers after excavation, impurity removal, and cleaning are fed into the aggregate bin 1, and are fed to the ton bag by the aggregate carrier chain 2 through the ton bag filling chain 4. The discharging platform 7 drives the ton bag to move down according to the discharging height until the bag is full. The aggregate bin 1, the aggregate carrier chain 2, and the ton bag filling chain 4 stop feeding when dumping the full ton bag, and the aggregate bin 1 serves to temporarily store the potato tubers.

[0035] The lifting movement of the material ton bag and the platform bottom plate 71 is realized by the lifting oil cylinder 76 driving the lifting mechanism 78. Its longitudinal movement remains straight up and down under the restriction of the guide rail mechanism 74.

[0036] When the material ton bag and the platform bottom plate 71 reach the lower dead point, the ton bag is filled with potato tubers. After the bag mouth is tied manually, the platform bottom plate 71 is tilted by the discharging oil cylinder 73, and under the action of gravity, the ton bag rolls on the discharging roller 72 until it slides to the ground.

[0037] After the platform bottom plate 71 is pulled horizontally by the discharging oil cylinder 73, a ton bag is manually added, and the ton bag mouth support 6 is used to prop up the four sides of the ton bag into a quadrilateral.

[0038] After the bottom of the empty ton bag is squeezed and kept at a constant position of 20-30 cm from the feeding point after the platform bottom plate 71 reaches the upper dead center, feeding is carried out. The bagging operation is completed in a cycle.

[0039] The loading and unloading mechanism is connected to the whole machine frame through the aggregate box connecting frame 12 and the frame connecting arm 9. During field transportation, the platform bottom plate 71 is changed from horizontal to vertical by the folding oil cylinder 75, and then the rotary oil cylinder 10 pulls the unloading platform 7 to rotate to be in the same direction as the forward direction of the unit to complete the conversion between the working state and the transportation state.
