Description
Technical Field
[0001] The utility model relates to the technical field of balers, in particular to a double-shift fork feeding device for a square baler. Background Art
[0002] When the square hay baler is working, its picker picks up the hay and transports it to the feeding part through the left and right augers, and then the hay is sent to the baling chamber through the reciprocating motion of the feeder pin in the filler assembly. The original feeder pin performs the reciprocating motion of grass-pulling alone. Since the pin returns to the grass-pulling position after a reciprocating motion, the hay has been piled up a lot at this time. Simply speeding up its movement speed cannot effectively solve the above problem. The feeder pin of the square hay baler of the utility model further optimizes the structure of the feeding device on the basis of the original solution, so that the hay can be quickly fed into the baling chamber without being piled up, thereby improving the working efficiency of the machine and the product quality.

DETAILED DESCRIPTION
[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings. Figure 1-5 A double-shift fork feeding device for a square baler is shown, comprising: a needle shifting connecting rod 1, a feeding arm plate 2, a double shift fork 3, a feeding crank 4, a fastener 5 and a transverse axis 6. The double shift fork 3 has two coplanar shifting needles. The two ends of the transverse axis 6 are rotatably connected to the feeding crank 4 and the feeding arm plate 2 respectively. The horizontal sections of the feeding crank 4 and the feeding arm plate 2 are coaxially arranged, and one end thereof is supported on the machine body. The needle shifting connecting rod 1 comprises two hinged rod sections, one end of one rod section is fixed on the machine body, and one end of the other rod section is fixed on the transverse axis 6. In this way, the power drives the feeding crank 4 to rotate and drives the transverse axis 6 to rotate. Due to the structure and position design of the needle shifting connecting rod 1, the reciprocating motion of the double shift fork 3 can be realized. Several fasteners 5 are fixed on the transverse axis 6, which are located between one end of the other rod section and the feeding crank 4. A double shift fork 3 of the same structure is installed on each fastener 5. As shown Figure 4 When the grass is transported from the picker 7 to the double fork 3, two pins distribute a part of it to the baling chamber in succession, which improves the defect of the original single pin reciprocating in one circle to transport the grass, reduces the grass blocking phenomenon caused by the accumulation of grass, and improves the operation efficiency of the machine.
[0021] In order to carry out the grass feeding operation, the initial positions of the relevant components in the double fork feeding device of the square baler of the utility model are set as follows: when the horizontal axis 6 is in the lowest position, the other section of the rod is perpendicular to the ground. At this time, the hinged position of the two rods is slightly higher than the axial position of the horizontal section of the feeding crank 4, and the tooth tip of the double fork 3 is slightly offset from the position perpendicular to the ground.
[0022] like Figure 2 and Figure 3The fastener 5 is a diamond-shaped kit with two connecting holes 501 at the diagonal positions. The double shift fork 3 also includes a shift fork 301, which is integrally connected to the roots of the two shift pins. The tooth tips of the two shift pins form an angle. The shift fork 301 is provided with a mounting hole 304, which is fixed to the connecting hole 501 by a bolt structure. When the horizontal axis 6 is at the lowest position, the position between the tooth tips of the two shift pins is perpendicular to the ground.
[0023] Preferably, the two dial pins are a short dial pin 302 and a long dial pin 303, the fork 301 is integrally connected with the roots of the short dial pin 302 and the long dial pin 303, the tips of the teeth of the short dial pin 302 and the long dial pin 303 form an angle, the tips of the teeth of the short dial pin 302 and the long dial pin 303 form a concave arc structure in the direction of feeding the grass, and the long dial pin 303 is located in the front position in the direction of feeding the grass, when the horizontal axis 6 is at the lowest position, the position between the tips of the teeth of the short dial pin 302 and the tips of the teeth of the long dial pin 303 is perpendicular to the ground. Figure 4 When the grass is transported from the picker 7 to the double fork 3, a portion of it can be first distributed to the baling chamber through the long pins, and then the short pins continue to send it into the baling chamber, which reduces the accumulation of grass and effectively reduces the phenomenon of grass blocking.
[0024] How to ensure the grass feeding rhythm of the two coplanar dial pins, the short dial pin 302 and the long dial pin 303, in the grass feeding direction is a question that needs to be considered during design. It is a good idea to design the distance between the short dial pin 302 and the long dial pin 303 according to the actual requirement of grass feeding without grass blocking. For the sake of simple measurement, the angle formed between the teeth and the root is used for calculation. Preferably, the angle formed between the tooth tip and the root of the short dial pin 302 and the long dial pin 303 is designed to be 45 degrees to ensure that grass is not blocked.
[0025] It is worth mentioning that the fork 301 mentioned above is integrally connected to the roots of the short and long pins 302 and 303. If the short and long pins 302 and 303 are designed separately, after the appropriate separation position between the short and long pins 302 and 303 is determined, they are fastened together to the fork 301 through a bolt structure, thereby realizing flexible adjustment of the positions of the two pins of the double fork 3 to adapt to new requirements of not blocking grass due to changes in grass feeding in actual work.
[0026] Fastening a row of double forks 3 with a large number on the horizontal axis 6 can increase the amount of grass delivered. Of course, too many double forks will also increase the deadweight, which tests the bearing capacity of the horizontal axis 6. In the actual manufacturing process, the number of double forks 3 and fasteners 5 is designed to be 4, and 4 double forks 3 form a row.
[0027] The working principle of this utility model:
[0028] like Figure 5The double fork 3 is fastened to the horizontal shaft 6 through a diamond-shaped kit. The horizontal shaft 6 makes a circular motion, and the double fork 3 makes a reciprocating motion. A portion of the hay can be distributed first and sent into the baling chamber by the long pin 303, and then continued to be sent into the baling chamber by the short pin 302, so as to reduce the accumulation of hay. The tooth tip of the long pin 303 reciprocates along the track a, and the tooth tip of the short pin 302 reciprocates along the track b.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
