Description

Clutch push-pull mechanism of straw round bale baler

Technical Field

The utility model belongs to the technical field of straw round bale bundling machines, and particularly relates to a clutch push-pull mechanism of a straw round bale bundling machine.

Background

In a 9YQ55-52 round bale bundling machine which is sold in the market, in the process of winding a net sheet on a bundled round bale, the original mechanism is that a micro cylinder enters air to push a shifting fork, so that a clutch is in a jogged state, and when a cylinder rod of the micro cylinder retracts, a reset spring enables the clutch to be in a cut-off state. When the outdoor operation is required, the air cylinder can not provide push-pull force without an air source.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the background art and provides a clutch push-pull mechanism of a straw round baler, which has the technical effect that when the straw round baler works in a farmland, a push-pull electromagnet is used for replacing an air cylinder to generate push-pull force to enable the clutch mechanism of the straw round baler to be embedded and separated.

The technical scheme provided by the utility model is as follows:

a clutch push-pull mechanism of a straw round bale baler comprises a frame, wherein a push-pull electromagnet, a shifting fork pin shaft seat and a rubber hanging roller are sequentially arranged on the frame, one end of the push-pull electromagnet is fixedly connected with the rack, one end of the shifting fork pin shaft seat is fixedly connected with the rack, one end of the rubber hanging roller is rotationally connected with the frame, the other end of the shifting fork pin shaft seat is rotationally connected with the middle part of the clutch shifting fork, the non-fork end of the clutch shifting fork is matched with the push-pull electromagnet, the rotating shaft of the rubber hanging roller penetrates through the transmission gear, a clutch assembly is slidably arranged on a rotating shaft of the rubber hanging roller, a return spring is arranged between the transmission gear and the clutch, the jaw end of the clutch shifting fork can drive the clutch assembly to slide on the rotating shaft of the rubber hanging roller and be embedded with the transmission gear, and the push-pull electromagnet is electrically connected with an external power supply.

The beneficial effects of the utility model are embodied in the following aspects:

Drawings

FIG. 1 is a schematic view of the overall structure of a clutch push-pull mechanism of a straw round baler.

In the figure: 1 rubber coating roller, 2 transmission gear, 3 reset spring, 4 clutch assembly, 5 clutch shift fork, 6 shift fork pin shaft seat, 7 push-pull electromagnet, 8 frames.

Detailed Description

The present invention will be further described with reference to the following detailed description, wherein the drawings are for illustrative purposes only and are not intended to be limiting, wherein certain elements may be omitted, enlarged or reduced in size, and are not intended to represent the actual dimensions of the product, so as to better illustrate the detailed description of the utility model.

2. As shown in fig. 1, a clutch push-pull mechanism of a straw round bale baler comprises a frame 8, a push-pull electromagnet 7, a shifting fork pin shaft seat and a rubber coating roller 1 are sequentially installed on the frame 8, one end of the push-pull electromagnet 7 is fixedly connected with the frame 8, one end of the shifting fork pin shaft seat is fixedly connected with the frame 8, one end of the rubber coating roller 1 is rotatably connected with the frame 8, the other end of the shifting fork pin shaft seat is rotatably connected with the middle part of a clutch shifting fork 5, the non-fork end of the clutch shifting fork 5 is matched with the other end of the push-pull electromagnet 7, a rotating shaft of the rubber coating roller 1 penetrates through a transmission gear 2, the transmission gear 2 is meshed with a power output gear so as to drive the transmission gear 2 to rotate, a clutch assembly 4 is slidably installed on the rotating shaft of the rubber coating roller 1, and a return spring 3 is installed between the transmission gear 2 and the clutch assembly 4, the jaw end of the clutch shifting fork 5 can drive the clutch assembly 4 to slide in the axial direction of the rotating shaft of the rubberizing roller 1 and be embedded with the transmission gear, at the moment, the clutch assembly 4 is matched with the axial key groove of the rubberizing roller 1, and the push-pull electromagnet is electrically connected with an external power supply.

When the rubber coating hanging roller is used, the push-pull electromagnet 7 is electrified, the push-pull electromagnet 7 generates 80N thrust, the clutch shifting fork 5 rotates around the shifting fork pin shaft seat 6, the fork head part of the clutch shifting fork 5 presses the clutch assembly 4, the clutch assembly 4 overcomes the spring resistance of the reset spring 3, the rubber coating hanging roller slides axially along the rubber coating hanging roller 1 until the rubber coating hanging roller is embedded with the transmission gear 2, and therefore the rubber coating hanging roller 1 rotates.

When the push-pull electromagnet 7 is powered off, the thrust of the electromagnet disappears, the thrust acting on the clutch assembly 4 disappears, the return spring 3 rebounds and resets, so that the clutch assembly 4 is separated from the embedded working state, and at the moment, the transmission gear 2 idles, so that the rubber hanging roller 1 is still.

This is novel according to push-and-pull electromagnet circular telegram and produces thrust, outage automatic re-setting's principle, fine realization is when the electro-magnet circular telegram, the core bar receives the electromagnetic force effect, produce thrust, the push clutch shift fork, make the clutch be in the gomphosis state, when the electro-magnet outage, the electro-magnet core bar leans on the spring to reset, then the clutch is in the state of cutting, when should meetting field work, when having not having had the air supply, the cylinder provides the technical problem that push-and-pull force just can't go through, and novel simple structure, high durability and convenient use, low in cost.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

While embodiments of the utility model have been disclosed above, it is not intended to be limited to the uses set forth in the specification and examples. It can be applied to all kinds of fields suitable for the present invention. All the above-mentioned electric components are matched and belong to the existent technology. Additional modifications will readily occur to those skilled in the art. It is therefore intended that the utility model not be limited to the exact details and illustrations described and illustrated herein, but fall within the scope of the appended claims and equivalents thereof.
