Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a folding mechanism of a rotary screen dust removal net. Background Art

[0002] The rotary screen dust removal net is used in straw recycling balers. This type of machine usually harvests the straw, transports it to the crushing bin through the machine's own conveying equipment for crushing, and then blows it to the rotary screen dust removal net through a fan for dust removal. Dust or fine particles will be screened out through the rotary screen dust removal net, and the remaining crushed material will fall into the extrusion baling bin for baling. The baled straw is usually used as animal feed.

[0003] At present, the rotary sieve dust removal net is tightly fixed on the machine by fasteners. The rotary sieve dust removal net is at the highest position. When passing through the height-restricted section, the rotary sieve dust removal net can only be removed to pass through the height-restricted section, which is quite inconvenient. Therefore, it is particularly important to apply for the design of a folding mechanism for the rotary sieve dust removal net.

[0004] The inventors have found at least the following problems in the process of implementing this embodiment:

[0005] The current rotary screen dust removal net is tightly fixed on the machine by fasteners and needs to be disassembled when passing through height-restricted sections, which is not convenient. Utility Model Content

[0009] The folding mechanism is installed on the agricultural machine;

[0010] The rotary screen dust removal net body is fixed to the upper side of the folding mechanism;

[0011] The folding mechanism comprises a hydraulic cylinder, a support frame, a stabilizing arm and a folding mounting plate;

[0012] The folding mounting plate is arranged on the upper side of the agricultural machine;

[0013] The rotary sieve dust removal net body is installed on the folding mounting plate;

[0014] One end of the folding mounting plate is hinged to the support frame;

[0025] Beneficial effects of the utility model:

[0026] The utility model provides a folding mechanism for a rotary screen dust removal net, which has a simple structure and a reasonable design. The rotary screen dust removal net body is fixedly mounted on the folding mechanism, and the folding mechanism can be folded. When there is a need to lower the height of the agricultural machinery, only the folding mechanism needs to be started, and the folding mechanism drives the rotary screen dust removal net body to rotate, and finally the folding action is completed, and the height of the agricultural machinery is lowered.

[0027] When the folding mechanism is started, the hydraulic cylinder is started and its output end contracts. The output end of the hydraulic cylinder pulls the support frame to start rotating, and the support frame pulls the folding mounting plate to start moving. When the folding mounting plate starts to move, it will also drive the rotation of the stabilizing arm. When the support frame rotates a certain angle and abuts against the limit frame, the hydraulic cylinder stops working. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-4 The folding mechanism of a rotary sieve dust removal net provided in the present embodiment is shown, comprising: a rotary sieve dust removal net body 100 and a folding mechanism 200; the folding mechanism 200 is installed on the agricultural machinery 300; the rotary sieve dust removal net body 100 is fixed to the upper side of the folding mechanism 200; the folding mechanism 200 comprises a hydraulic cylinder 210, a support frame 220, a stabilizing arm 230 and a folding mounting plate 240; the folding mounting plate 240 is arranged on the upper side of the agricultural machinery 300; the rotary sieve dust removal net body 100 is installed on the folding mounting plate 240; one end of the folding mounting plate 240 is hinged to the support frame 220; the other end of the support frame 220 is hinged to the agricultural machinery 300; the top end of the hydraulic cylinder 210 is hinged to the support frame 220; the bottom end of the hydraulic cylinder 210 is hinged to one side of the agricultural machinery 300; the other end of the folding mounting plate 240 is hinged to the stabilizing arm 230; the other end of the stabilizing arm 230 is hinged to the agricultural machinery 300.

[0038] Specifically, the folding mechanism 200 can complete the folding action when the rotary screen dust removal net body 100 is not in use, drive the rotary screen dust removal net body 100 to complete the folding, reduce the height of the agricultural machine 300, and improve the passability of the agricultural machine 300.

[0039] Furthermore, a fixing seat 310 is fixedly installed on the agricultural machine 300 , and the bottom end of the support frame 220 is hinged to the fixing seat 310 .

[0040] Furthermore, a cylinder seat 320 is fixedly mounted on the agricultural machine 300 , and the bottom end of the hydraulic cylinder 210 is hinged to the cylinder seat 320 .

[0041] Furthermore, a side plate 340 is fixedly mounted on the agricultural machine 300 , and the bottom end of the stabilizing arm 230 is hinged to the side plate 340 .

[0042] Specifically, when the folding mounting plate 240 moves, the stabilizing arm 230 hinged thereto supports the end of the folding mounting plate 240 to ensure its stability during movement.

[0046] The working principle of this utility model:

[0047] When the rotary screen dust removal net body 100 needs to be folded, the hydraulic cylinder 210 is started, and its output end contracts. The output end of the hydraulic cylinder 210 pulls the support frame 220 to start rotating, and the support frame 220 pulls the folding mounting plate 240 to start moving. When the folding mounting plate 240 starts to move, it also drives the rotation of the stabilizing arm 230. When the support frame 220 rotates a certain angle, it abuts against the limit frame 330, and the hydraulic cylinder 210 stops working.

[0048] When it is necessary to restore the position of the rotating screen dust removal net body 100, the hydraulic cylinder 210 is started and its output end is extended. The output end of the hydraulic cylinder 210 starts to rotate against the support frame 220, and the support frame 220 starts to move against the folding mounting plate 240. When the folding mounting plate 240 starts to move, it also drives the rotation of the stabilizing arm 230. After the support frame 220 rotates a certain angle, the folding mounting plate 240 is located on the upper side of the agricultural machinery 300. At this time, the hydraulic cylinder 210 stops working.
