It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts, unless otherwise specified.

Example 1

The automatic elephant grass seed stem cutting machine shown in figures 1-3 comprises a frame 1, and a first motor, a bending plate 4, a supporting device, a connecting rod 7, a feeding chute 6, a cutting device and a starting switch 3 which are arranged on the frame. The upper portion of frame 1 is equipped with workstation 13, strutting arrangement and feed chute 6 divide to be listed as in the relative both sides of workstation 13, strutting arrangement includes supporting seat 52, pivot 51, the both ends of pivot 51 rotate with supporting seat 52 respectively and are connected, and two supporting seats 52 pass through the bolt fastening on workstation 13 for pivot 52 is parallel with feed chute 6. A supporting platform 12 is further arranged below the workbench 13, and the first motor is mounted on the supporting platform 12 through bolts. The bending plate 4 comprises a first mounting plate 42 and a second mounting plate 41, the first mounting plate 42 and the second mounting plate 41 are welded and fixed at an angle, and one side of an included angle formed by the first mounting plate 42 and the second mounting plate 41 is the inner side. The inner side surface of the first mounting plate 42 is welded and fixed on the rotating shaft 51, and the end part of the outer side surface, which is far away from the second mounting plate 42, is fixed with a cutting device, so that the bending plate 4 can do reciprocating motion (similar to a seesaw) with a certain amplitude through the rotating shaft 51. The end part of the output shaft of the first motor is fixed with a flange 2, 4-6 connecting holes 21 are arranged around the flange 2, and the distances from the connecting holes 21 to the center point of the flange 2 are different. The upper end of the connecting rod 7 is hinged with the bending plate 4, and the lower end of the connecting rod is hinged with one of the connecting holes 21 of the flange plate 2 in a pin shaft connecting mode, so that the first motor, the connecting rod 7 and the bending plate 4 form a connecting rod mechanism. The cutting device is an electric saw 36, the electric saw 36 is arranged on the outer side surface of the first mounting plate 42, and a saw blade 35 of the electric saw 36 faces the port of the feed chute 6 and can cut off seed stems extending out of the port of the feed chute 6. The starting switch 3 is fixed on the frame 1 and used for controlling the power output states of the first motor and the cutting device. The support seat 52 may be a bearing seat. In the preferred embodiment, the first mounting plate 42 and the second mounting plate 41 are welded at 90 ° to each other.

The working principle is as follows: the first motion state is that a first motor is used as power to drive the connecting rod mechanism to move, so that the bending plate 4 is driven to do reciprocating motion (like a seesaw to do reciprocating motion along with a shaft) with a certain amplitude through the rotating shaft 51, and the saw blade 35 is driven to circularly do motion close to the port of the feed chute 6 for cutting and far away from the port of the feed chute 6; another state of motion is that the power saw 36 is activated. When cutting seed stems, a connecting rod mechanism is formed by the first motor, the connecting rod 7 and the bending plate 4, and under the condition that the first motor is started, the bending plate 4 reciprocates, so that the saw blade 35 of the electric saw 36 fixed on the first mounting plate 42 is circularly close to or far away from a port of the feeding chute 6, and the purposes of being close to cutting and keeping away from discharging are achieved.

Specifically, still include and fill up flat piece 43, connecting block 23, the one end fixed connection of connecting rod 7 connecting block 23, the other end is articulated with filling up flat piece 43, connecting block 23 rotates with the connecting hole 21 of ring flange 2 and is connected, fill up flat piece 43 and second mounting panel 41 fixed connection. Utilize the connection face flatness of the connection board 7 and first motor, first mounting panel 42 of the flat piece 43 of pad and connecting block 23 regulation, improve job stabilization nature.

More specifically, the feed chute 6 is a channel steel with an upward opening, and the bottom of the channel steel is welded and fixed on a workbench 13 of the frame 1. In order to reduce the friction between the elephant grass seed stems and the channel steel 6, a round iron column 61 is welded at the included angle at the bottom of the channel steel. To improve safety in use, a shield is provided on the outside of the saw blade 35 to prevent debris from splashing and to prevent accidental injury to the operator.

To facilitate collection of the cut seed stems, a seed stem recovery tank 8 is provided below the saw blade 35. The upper part of the seed stem recovery box 8 is an open opening, and the lower part is a square discharge hole 81 which is gradually furled. The outer side of the seed stem recovery box 8 is provided with a stand 84, and an arc-shaped guide piece 83 is welded and fixed on one side of the discharge hole 81, so that the cut seed stems are guided to be away from the cutting machine.

Example 2

Referring to fig. 4-6, the present embodiment is different from embodiment 1 in that the structure and arrangement of the cutting device are slightly different. Specifically, the cutting device comprises a motor 32, a driven shaft 31 and a saw blade 35, wherein the driven shaft 31 fixes the outer side surface of the first mounting plate 42 through a bearing seat and is far away from the second mounting plate 41, namely, is located at the mounting position of the electric saw 36 in embodiment 1, and the motor 32 is fixed on the outer side surface of the second mounting plate 41 through a bolt. One end of the driven shaft 31 is provided with the saw blade 35, and the other end is in transmission connection with the motor 32 through a belt 33, so that power transmission is realized. The heavy motor 32 is mounted on the second mounting plate 41, so that the bending plate 4 normally tends to tilt toward the second mounting plate 41 due to the self-weight of the motor 32, thereby raising the saw blade 35 mounted on the first mounting plate 42 upward.
