Description

Technical Field

[0001] The present invention relates to a feed harvester, and particularly to a foldable feed harvester thrower tube. Background Art

[0002] At present, in order to accurately control the ejection height and distance of the feed, the thrower tube of the existing feed harvester is usually set relatively long, which brings great inconvenience to transportation. However, in actual operation, the thrower tube before work is usually slightly adjusted by a hydraulic cylinder, or the length and height of the thrower tube are directly positioned manually using a locking mechanism, and after work, it is lowered and retracted to solve the transportation inconvenience problem. This method completely relies on manual labor, resulting in inflexible adjustment of the structural parameters of the thrower tube, insignificant adjustment effect, etc., and it is time-consuming and laborious to operate. Summary of the Invention

[0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a foldable feed harvester thrower tube, which has a simple structure, reliable performance, and is simple and convenient to operate. By automatically splicing and locking and shrinking and folding the thrower tube, problems such as inconvenience in transportation of the existing thrower tube are solved.

[0004] The present invention adopts the following technical solutions:

[0005] A foldable feed harvester thrower tube includes a first thrower tube, a second thrower tube, a third thrower tube and a connecting member. Both ends of the second thrower tube are respectively connected to the first thrower tube and the third thrower tube through the connecting member. The first thrower tube is connected to the discharge port of the crushing mechanism of the feed harvester through a base connection flange. The connecting member can drive the first thrower tube, the second thrower tube and the third thrower tube along the central axis to perform shrinking and folding and splicing and locking operations respectively through a hydraulic motor.

[0006] The connecting member includes a first connecting member and a second connecting member. The first connecting member is connected to the first thrower tube and the second thrower tube, and the second connecting member is connected to the second thrower tube and the third thrower tube.

The hydraulic motor is installed on the motor fixing plate of the second connecting end face base plate. The hydraulic motor is provided with a large gear through a coupling, and the large gear meshes with the fixed pinion gear. The fixed pinion gear is fixed on the central shaft. One side of the first connecting end face base plate is fixedly connected to the central shaft, and one side of the second connecting end face base plate is rotatably connected to the central shaft. The motor fixing plate can drive the second connecting end face base plate to rotate around the central shaft. The first connecting end face base plate and the second connecting end face base plate are respectively fixedly connected to the first throwing cylinder and the second throwing cylinder through screws provided in the reserved screw holes.

[0008] The structure of the described second connecting member is the same as that of the first connecting member. The second connecting member is fixedly connected to the second throwing cylinder through the second connecting end face base plate, and the first connecting end face base plate is fixedly connected to the third throwing cylinder, so that the central shaft of the first connecting member is located on the right side of the first throwing cylinder and the second throwing cylinder, and the central shaft of the second connecting member is located on the left side of the second throwing cylinder and the third throwing cylinder.

Detailed implementation mode

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and the detailed implementation mode.

[0019] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a foldable feed harvester throwing cylinder includes a first throwing cylinder 1, a second throwing cylinder 2, a third throwing cylinder 3 and connecting pieces. Both ends of the second throwing cylinder 2 are respectively connected to the first throwing cylinder 1 and the third throwing cylinder 3 through the connecting pieces. The first throwing cylinder 1 is connected to the discharge port of the crushing mechanism of the feed harvester through the base connection flange 14. The connecting pieces can drive the first throwing cylinder 1, the second throwing cylinder 2 and the third throwing cylinder 3 to perform contraction folding and splicing locking operations along the central shaft 12 through the hydraulic motor 6.

[0020] The connecting pieces include a first connecting piece 4 and a second connecting piece 5. The first connecting piece 4 is connected to the first throwing cylinder 1 and the second throwing cylinder 2. The second connecting piece 5 is connected to the second throwing cylinder 2 and the third throwing cylinder 3.

[0021] The first connecting piece 4 includes a hydraulic motor 6, a fixed small gear 8, a first connecting end face base plate 10, a second connecting end face base plate 11 and a central shaft 12 that intersects and connects the first connecting end face base plate 10 and the second connecting end face base plate 11 in a hinge manner. The hydraulic motor 6 is installed on the motor fixing plate 9 of the second connecting end face base plate 11. The motor fixing plate 9 is vertically fixed on the second connecting end face base plate 11. The hydraulic motor 6 is provided with a large gear 7 through a coupling. The large gear 7 meshes with the fixed small gear 8. The fixed small gear 8 is fixed on the central shaft 12. One side of the first connecting end face base plate 10 is fixedly connected to the central shaft 12. One side of the second connecting end face base plate 11 is rotatably connected to the central shaft 12. The motor fixing plate 9 can drive the second connecting end face base plate 11 to rotate around the central shaft 12. The first connecting end face base plate 10 and the second connecting end face base plate 11 are respectively fixedly connected to the first throwing cylinder 1 and the second throwing cylinder 2 through screws arranged in the reserved screw holes 13.

[0022] The second connecting member 5 has the same structure as the first connecting member 4. The second connecting member 5 is fixedly connected to the second throwing cylinder 2 through the second connecting end face base plate 11, and the first connecting end face base plate 10 is fixedly connected to the third throwing cylinder 3, so that the central axis 12 of the first connecting member 4 is located on the right side of the first throwing cylinder 1 and the second throwing cylinder 2, and the central axis 12 of the second connecting member 5 is located on the left side of the second throwing cylinder 2 and the third throwing cylinder 3.

[0023] Working principle:

[0024] After the spraying operation of the feed is completed, the method of shrinking and folding the throwing cylinder is as follows: By starting the hydraulic motor 6 with low speed and high torque, the hydraulic motor 6 drives the large gear 7 to rotate counterclockwise through the coupling. The large gear 7 and the fixed small gear 8 rotate meshingly counterclockwise, and the second throwing cylinder 2 rotates to the left and folds. The maximum rotation angle can reach 180°.

[0025] Before the feed spraying operation, the method of extending and splicing the throwing cylinder is as follows: When the hydraulic motor 6 drives the large gear 7 to rotate clockwise, the large gear 7 and the fixed small gear 8 rotate meshingly clockwise. The second throwing cylinder 2 is driven by the second connecting end face base plate 11 to rotate to the right and splice. When the second throwing cylinder 2 is butted against the first throwing cylinder 1, the hydraulic motor 6 stops working, and the second throwing cylinder 2 and the first throwing cylinder 1 are connected and locked by the meshing of the large gear 7 of the hydraulic motor 6 and the fixed small gear 8.

[0026] The operation and connection method of the second throwing cylinder 2 and the third throwing cylinder 3 are the same as those of the first throwing cylinder 1 and the second throwing cylinder 2. The difference is that the third throwing cylinder 3 rotates to the right relative to the second throwing cylinder 2 for shrinking and folding, and rotates to the left for expanding and splicing. Considering that the third throwing cylinder 3 is longer than the second throwing cylinder 2 and the first throwing cylinder 1, during the shrinking and folding process, the third throwing cylinder 3 is first shrunk and folded, and then the second throwing cylinder 2 is shrunk and folded. During the elongation and splicing process, the second throwing cylinder 2 needs to be elongated first and then the third throwing cylinder 3. This order of use can also be flexibly adjusted according to the actual situation.

[0027] Through the above structure, the driver only needs to operate the hydraulic control handle in the driver's seat to control the hydraulic motor, and can realize the automatic expansion, splicing, shrinking and folding operation of the first throwing cylinder 1, the second throwing cylinder 2 and the third throwing cylinder 3 before or after the work starts. This not only reduces the labor intensity of the driver, improves the working efficiency of the harvester, but also reduces the volume of the whole machine, facilitates transportation, and avoids the collision damage of the throwing cylinder during transportation.

[0028] The above is described by way of example, but the present invention is not limited to the specific forms disclosed above. It should be understood that all variations or substitutions of the technical solution of the present invention by those skilled in the art do not depart from the spirit and scope of protection of the technical solution of the present invention.
