Description

Technical Field

[0001] The utility model relates to the technical field of mechanized harvesting equipment, in particular to a rope box supporting device for a square baler. Background Art

[0002] With the rapid development of my country's economy, the development trend of animal husbandry is good, and the demand for forage is increasing. Natural forage can no longer meet the needs of animal husbandry development. Therefore, corn straw and wheat straw have gradually become forage for animal husbandry in some areas.

[0003] Mechanized forage harvesting technology has very mature experience in advanced European and American countries. There are also many types of mechanized harvesting. The most commonly used mechanized harvesting equipment are square hay balers and round hay balers.

[0004] In traditional square hay balers, the rope box is used to store the baling rope. The rope box cover is usually supported by hand or gas spring during the opening and closing process. That is, the rope box cover is supported by a support rod so that the rope box cover can be opened and closed at a certain angle to facilitate the placement of the baling rope. The gas spring support has a relatively wide range of uses. The gas spring consists of a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, a filler, a control element inside the cylinder, a control element outside the cylinder, and a joint. Inert gas is filled into the closed pressure cylinder to make the pressure inside the cavity much higher than the atmospheric pressure to achieve the movement of the piston rod. However, the gas spring is expensive to manufacture, and long-term use may cause gas leakage, resulting in insufficient support force and injury to the arm, which poses certain risks.

[0040] In the embodiment of the present application, the upper connecting rod passes through the upper support rod 7 and the upper connecting plate 10 in sequence, and the upper spacer 11 is used to prevent the upper support rod 7 from falling off from the upper connecting rod.

[0041] Exemplarily, the connection between the rope box 4 and the rope box cover 3 is hinged through the support plate 2.

[0042] In the embodiment of the present application, the two ends of the support plate 2 are respectively hinged to the rope box 4 and the rope box cover 3, so as to realize the rotation connection between the rope box cover 3 and the rope box 4.

[0043] Exemplarily, a lower bottom plate 9 is provided in the rope box 4 , and the first end of the lower support rod 13 is hinged to the lower bottom plate 9 .

[0044] In the embodiment of the present application, the lower base plate 9 spans across the interior of the rope box 4 and is used to connect the lower support rod 13 .

[0045] Exemplarily, a lower connecting plate 14 is disposed on the lower base plate 9 , and the first end of the lower supporting rod 13 is hinged to the lower connecting plate 14 .

[0046] In the embodiment of the present application, the lower connecting plate 14 is welded to the lower base plate 9 to connect the lower supporting rod 13 .

[0047] Exemplarily, the first end of the lower support rod 13 is hinged to the lower connecting plate 14 via a lower connecting rod, and a lower spacer is provided on the lower connecting rod, and the lower spacer abuts against the lower support rod 13 .

[0048] In the embodiment of the present application, the lower connecting rod passes through the lower supporting rod 13 and the lower connecting plate 14 in sequence, and the lower spacer is used to prevent the lower supporting rod 13 from falling off from the lower connecting rod.

[0049] Exemplarily, a receiving groove 1 is provided on the lower base plate 9 , and when the rope box cover 3 is tightly closed on the rope box 4 , the upper support rod 7 and the lower support rod 13 are received in the receiving groove 1 .

[0050] In the embodiment of the present application, when the rope box cover 3 is completely and tightly closed on the rope box 4, the upper support rod 7 and the lower support rod 13 are stored in the accommodating groove 1. When the rope box cover 3 is rotated to disengage from the rope box 4, the upper support rod 7 and the lower support rod 13 gradually disengage from the accommodating groove 1.

[0051] The present application provides a square baler rope box support device which achieves the function of supporting the rope box cover by clamping the baffle on the lower support rod at the notch on the upper support rod. Since the upper support rod and the lower support rod are connected by a dead point, they have high stability and are not easy to fall off and cause the rope box cover to fall and injure the arm.
