[0001] This utility model relates to the field of agricultural machinery technology, specifically to a harvester's motorized blade assembly. Background Technology

[0002] In existing harvester technology, the moving blade assembly is one of the key components of the harvester. Its performance directly affects the effect and efficiency of harvesting operations and has a vital impact on agricultural production.

[0003] In the prior art, such as in the publication number CN205812796U, a harvester's motorized blade assembly is disclosed. It includes a moving blade assembly body, a spiral blade assembly, a positioning post, a groove, a positioning opening, a rotating shaft, and a supporting steel plate assembly. The moving blade assembly body is provided with a positioning post, with grooves at both ends of the positioning post. The grooves have positioning openings, and the rotating shaft passes through the positioning post and extends out from the positioning opening. The positioning post is provided with a spiral blade assembly, and the front end of the spiral blade assembly is provided with a supporting steel plate assembly. The spiral blade assembly and the supporting steel plate assembly are adapted to each other, resulting in a simple and reasonable structure, a wide cutting area for the spiral blade, and a stable connection between the spiral blade and the positioning post.

[0004] Based on the above-mentioned prior art, the existing harvester's motorized blade combination still has the following problems. The existing technology uses a rotating shaft to drive the blade to rotate to achieve the cutting effect. However, when the blade is rotating and cutting, the stem is easily wrapped around the blade, which affects the normal progress of the harvesting operation. Therefore, this utility model provides a harvester's motorized blade combination. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a harvester's motorized blade combination, which solves the problem that when the blades are rotating and cutting, the stems are easily entangled on the blades, which affects the normal progress of the harvesting operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a harvester's motorized blade assembly, comprising a U-shaped frame, a guide groove extending through the outer surface of the U-shaped frame, and a cutting assembly mounted on the U-shaped frame, the cutting assembly comprising:

[0007] A moving component is mounted on a U-shaped frame. The U-shaped frame includes a moving blade holder mounted inside the U-shaped frame. Multiple upper cutting blades are mounted on the bottom of the moving blade holder. A guide block is fixedly connected to the rear surface of the moving blade holder, and the guide block can slide freely along the inner wall of the guide groove.

[0008] A stationary component is disposed inside a U-shaped frame. The U-shaped frame includes a stationary blade holder fixedly installed on the bottom surface of the U-shaped frame. Multiple lower cutting blades are installed on the top of the stationary blade holder, and the top surface of the lower cutting blades contacts the bottom surface of the upper cutting blades.

[0009] Preferably, a movable block is fixedly connected to the rear surface of the guide block, the movable block is placed outside the U-shaped frame, and a straight groove is opened on the top surface of the movable block.

[0010] Preferably, the moving component further includes a protective shell mounted on the surface of the U-shaped frame, a motor is mounted on the top surface inside the protective shell, a connecting rod is mounted on the output shaft end of the motor, an eccentric shaft is mounted on the bottom surface of the connecting rod, and the eccentric shaft is movably positioned inside the straight groove.

[0011] Preferably, a base plate is installed on the bottom surface of the U-shaped frame, and multiple protective plates are fixedly connected to the front surface of the base plate.

[0012] Preferably, two connecting rods are installed on the rear surface of the U-shaped frame, and rod sleeves are slidably sleeved on the outer wall of the connecting rods, with a connecting plate installed between the ends of the two rod sleeves.

[0013] Preferably, a groove is provided through the outer wall of the sleeve, and a slider is fixedly connected to the outer wall of the connecting rod, and the slider can slide freely along the inner wall of the groove.

[0014] Beneficial effects

[0015] This utility model provides a harvesting motorized blade assembly. Compared with the prior art, it has the following advantages:

[0016] (1) The harvester's moving blade assembly drives the connecting rod to rotate by starting the motor in the assembly, so that the eccentric shaft moves in the straight groove of the moving block, causing the moving block to reciprocate linearly, so that the guide block slides on the inner wall of the guide groove, thereby driving the moving blade holder to reciprocate. Since the lower cutting blade is fixed in position, when the upper cutting blade reciprocates, it can cut the crop stalks to achieve the harvesting function. In this process, because the relative movement of the upper and lower cutting blades is reciprocating rather than rotating, the stalks can be effectively prevented from getting tangled on the blades.

[0017] (2) In the actual harvesting operation, when obstacles such as stones appear on the ground, the guard plate first contacts the stones. Due to the obstruction of the guard plate, a corresponding force will be generated. This force will transfer the impact force of the stones to the U-shaped frame, causing the U-shaped frame to move upward against its own weight, preventing the stones from directly impacting the upper and lower cutting blades, avoiding damage such as chipping and rolling of the blades due to direct collision with the stones, and greatly improving the service life and durability of the blades.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides two technical solutions:

[0025] Figures 1-4 The first embodiment is shown: a harvester's motorized blade assembly, including a U-shaped frame 1, a guide groove 11 extending through the outer surface of the U-shaped frame 1, and a cutting assembly mounted on the U-shaped frame 1, the cutting assembly including:

[0026] The moving component 2 is set on the U-shaped frame 1. The U-shaped frame 1 includes a moving blade holder 21 set inside the U-shaped frame 1. Multiple upper cutting blades 22 are installed at the bottom of the moving blade holder 21. A guide block 23 is fixedly connected to the rear surface of the moving blade holder 21, and the guide block 23 can slide freely along the inner wall of the guide groove 11.

[0027] The stationary component 3 is located inside the U-shaped frame 1. The U-shaped frame 1 includes a stationary blade holder 31 fixedly installed on the bottom surface of the U-shaped frame 1. Multiple lower cutting blades 32 are installed on the top of the stationary blade holder 31, and the top surface of the lower cutting blades 32 contacts the bottom surface of the upper cutting blades 22.

[0028] A movable block 24 is fixedly connected to the rear surface of the guide block 23. The movable block 24 is placed outside the U-shaped frame 1. A straight groove 25 is opened on the top surface of the movable block 24. The moving component 2 also includes a protective shell 26 installed on the surface of the U-shaped frame 1. A motor 27 is installed on the top surface inside the protective shell 26. A connecting rod 28 is installed at the output shaft end of the motor 27. An eccentric shaft 29 is installed on the bottom surface of the connecting rod 28, and the eccentric shaft 29 is movably placed inside the straight groove 25.

[0029] Specifically, the motor 27 starts and drives the connecting rod 28 to rotate, which in turn rotates the eccentric shaft 29. The rotation of the eccentric shaft 29 pushes the movable block 24 to make reciprocating linear motion, which in turn drives the moving blade holder 21 to make reciprocating motion along the guide groove 11, causing the upper cutting blade 22 to move accordingly. The upper cutting blade 22 has relative motion with respect to the lower cutting blade 32. This relative motion is similar to the shearing principle of scissors. The upper cutting blade 22 constantly moves closer to and further away from the lower cutting blade 32. The blades of the two work together to cut the crop stems during the reciprocating motion, thus achieving the cutting function. Compared with the traditional rotary cutting method, this reciprocating shearing motion can avoid the stems from getting tangled on the blades, achieving a more stable and efficient harvesting effect.

[0030] Figures 1-4 The second embodiment is shown, and the main difference from the first embodiment is that: a base plate 4 is installed on the bottom surface of the U-shaped frame 1, and a plurality of protective plates 41 are fixedly connected to the front surface of the base plate 4; two connecting rods 5 are installed on the rear surface of the U-shaped frame 1, and rod sleeves 51 are slidably sleeved on the outer wall of the connecting rods 5, and a connecting plate 54 is installed between the ends of the two rod sleeves 51; a sliding groove 52 is opened through the outer wall of the rod sleeve 51, and a slider 53 is fixedly connected to the outer wall of the connecting rod 5, and the slider 53 can slide freely along the inner wall of the sliding groove 52.

[0031] Specifically, during the harvesting process, when encountering stones or other obstacles on the ground, the guard plate 41 will first come into contact with these obstacles. Because the guard plate 41 is fixedly connected to the base plate 4, when the guard plate 41 is subjected to the impact force from the obstacle, it will transfer the impact force to the base plate 4, thereby pushing the entire U-shaped frame 1 to move upward. This can prevent stones or obstacles from directly contacting the upper cutting blade 22 and the lower cutting blade 32, prevent damage to the blades, and extend the service life of the blades.

[0032] When the U-shaped frame 1 moves up and down due to ground conditions, the connecting rod 5 will slide up and down inside the sleeve 51, and the slider 53 will slide along the groove 52, which plays a guiding and limiting role, ensuring that the movement of the U-shaped frame 1 is smooth.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the motor 27 in component 2 is first started, which drives the connecting rod 28 to rotate, causing the eccentric shaft 29 to move within the straight groove 25 of the movable block 24. This causes the movable block 24 to reciprocate linearly, causing the guide block 23 to slide on the inner wall of the guide groove 11. This, in turn, drives the moving blade holder 21 to reciprocate. Since the lower cutting blade 32 is fixed in position, when the upper cutting blade 22 reciprocates, it can cut the crop stalks, thus achieving the harvesting function. In this process, because the relative movement between the upper cutting blade 22 and the lower cutting blade 32 is reciprocating rather than rotating, it can effectively prevent the stalks from getting tangled on the blades, overcoming the problems mentioned in the background art.

[0035] During actual harvesting operations, when obstacles such as stones appear on the ground, the guard plate 41 first contacts the stones. Due to the obstruction of the guard plate 41, a corresponding force is generated. This force will transfer the impact force of the stones to the U-shaped frame 1, causing the U-shaped frame 1 to move upward against its own weight, preventing the stones from directly impacting the upper cutting blade 22 and the lower cutting blade 32. This avoids damage such as chipping or rolling of the blades due to direct collision with the stones, greatly improving the service life and durability of the blades. When the stones cause the U-shaped frame 1 to move up and down, the connecting rod 5 slides inside the rod sleeve 51, thereby enabling the U-shaped frame 1 to adapt to different heights and maintain the stability of the structure.
