[0002] With the development of society and technology, equipment in various fields has been greatly improved. Silage machines are mainly agricultural equipment for harvesting silage crops such as corn and sorghum. They crush and separate the corn stalks before cutting them, and both dry and wet corn stalks can be used. The crushing roller is one of the important accessories in the silage machine. In order to improve the quality of subsequent silage, the crushing roller gap adjustment device is generally used to adjust the actual crushing roller gap accordingly, which greatly shortens the adjustment time.

[0003] After searching, the publication number CN220496487U, application date 2023.06.26 discloses a crushing roller gap adjustment device for a silage machine, including two mounting side plates, a limiting rod is passed through the top of the two mounting side plates on opposite sides, both ends of the limiting rod are rotatably connected with an adjustment assembly, the rear sides of the tops of the two mounting side plates are fixedly connected to the limiting plates, and the front sides of the tops of the two mounting side plates are fixedly connected to mounting blocks; the adjustment assembly includes an offset wheel and a locking stud. The utility model adopts a wedge block design instead of direct adjustment with bolts, increases the contact surface, reduces the wear of the end face due to back and forth impact, and causes gap changes; changes the direction of the adjustment action, leaves a limiting groove in the middle of the wedge block, and the extreme position can also prevent the rollers from colliding; changes the action position from point contact to surface contact, reduces the gap change caused by impact wear; adopts a four-bar linkage mechanism to change the adjustment position, which is convenient for the adjustment operation.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned crushing roller gap adjustment device for silage machine realizes the limiting and adjustment effect of the first crushing roller through locking studs, adjusting nuts, etc. during use. However, this method is relatively cumbersome and time-consuming, labor-intensive, and has low work efficiency during the operation of the staff. In addition, the height position of the adjusting nuts on both sides cannot be accurately adjusted, which will affect the normal use effect of the first crushing roller.

[0006] 2. The above-mentioned crushing roller gap adjustment device for silage machine plays a buffering role when adjusting the first crushing roller through a single-sided buffer spring during use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0033] See also Figures 1 to 4 The utility model is a crushing roller gap adjustment device for a silage machine, comprising a front mounting seat 1 and a rear mounting seat 2 arranged directly behind the front mounting seat 1, a convex plate 104 is fixedly connected to the center position of the outer wall of one side of the front mounting seat 1 and the rear mounting seat 2, a rack 105 is rotatably connected to the center position of the outer wall of the convex plate 104, a plug-in frame 1029 is sleeved on the upper outer side of the outer wall of the rack 105, and a limiting component 3 is arranged on the front and rear end surfaces of the plug-in frame 1029; the limiting component 3 comprises a card plate 301 and a rotating rod 302 installed at the center position of the inner wall thereof through a connecting block, and a torsion spring 303 is sleeved on the outer side of the outer wall of the rotating rod 302.

[0034] Specifically, a left crushing roller 101 is installed on one side of the opposite end faces of the front mounting seat 1 and the rear mounting seat 2, and a right crushing roller 102 is installed on the other side of the opposite end faces of the front mounting seat 1 and the rear mounting seat 2. One side of the outer wall of the front mounting seat 1 and the rear mounting seat 2 is fixedly connected to a limiting plate 103. The front and rear end faces of the right crushing roller 102 are both provided with an eccentric shaft 1021. The outer wall of the eccentric shaft 1021 is sequentially sleeved with a fixing sleeve 1022 and a gear ring 1024 from the inside to the outside. A support plate 1023 is fixedly connected to the bottom of the outer wall of one side of the fixing sleeve 1022. A limiting roller 1025 is rotatably connected between the opposite end faces of the front and rear adjacent fixing sleeves 1022. The inner part of the limiting roller 1025 The two ends of the rotating shaft pass through the bearings on the inner wall of the adjacent fixed sleeve 1022 and are connected to the adjacent adjusting plate 1026. A connecting rod 1027 is movably connected at the edge of one end of the adjusting plate 1026. The other end of the connecting rod 1027 is movably connected to the wedge block 1028 through a hinge. The wedge block 1028 is located on one side of the gear ring 1024. The other end of the inner wall of the adjusting plate 1026 is movably connected to a plug-in frame 1029. A pressure rod 10210 is fixedly connected to one side of the top of the opposite end faces of the front and rear adjacent plug-in frames 1029. The two ends of the rotating rod 302 are respectively installed in the bearings on the inner walls of the adjacent side plates 304, and one end face of the side plate 304 is fixed to the outer wall of the plug-in frame 1029.

[0035] Furthermore, the outer wall of the rack 105 is evenly spaced with card slots, and the size of the card slots is slightly larger than the size of the horizontal section of the card plate 301. The cross section of the card plate 301 is L-shaped. When subjected to force, it will rotate with the rotating rod 302 as the center of the circle. Under the elastic performance of the torsion spring 303, the card plate 301 can be driven to rotate. The adjustment principle and most of the structures of the adjustment device are existing technologies, so they will not be elaborated here. The limiting roller 1025 limits the position of the right crushing roller 102, and the wedge block 1028 is meshed with the outer wall of the gear ring 1024 to play a transmission role.

[0036] The operation process of this embodiment is as follows: when it is necessary to adjust the gap between the left crushing roller 101 and the right crushing roller 102, first push the bottom of the outer card plate 301 of the plug-in frame 1029 inward, and the bottom of the card plate 301 is subjected to force to rotate around the rotating rod 302 as the center of the circle, and squeeze the torsion spring 303. Since the cross-section of the card plate 301 is L-shaped, the horizontal end of the card plate 301 can be moved out of the card slot on the outer wall of the rack 105, and then an upward pulling force or a downward pressure is applied to the pressure rod 10210. The pressure rod 10210 is subjected to force through the plug-in frame 1029 to drive the adjustment plate 1026 to rotate around the central rotating shaft in the limiting roller 1025 as the center of the circle, which can drive the other end of the adjustment plate 1026 to rotate around the central rotating shaft in the limiting roller 1025 as the center of the circle to make an arc motion, and then in the connecting rod 1029, the adjustment plate 1026 is connected to the connecting rod 1029. The wedge block 1028 can be driven to move under the action of the moving rod 1027 and the hinge. Since the outer wall of the wedge block 1028 is meshed with the gear on the outer wall of the gear ring 1024, the gear ring 1024 will be driven to rotate when the wedge block 1028 moves, and the right crushing roller 102 will be rotated around the eccentric shaft 1021 under the action of the eccentric shaft 1021, so as to achieve the purpose of adjusting the gap between the left crushing roller 101 and the right crushing roller 102. After the adjustment is completed, stop applying force to the bottom of the card plate 301. At this time, under the action of the elastic performance of the torsion spring 303, the card plate 301 is re-rebounded into the inside of the plug-in frame 1029 and inserted into the card slot on the outer wall of the rack 105, which plays a role of limiting, making it convenient for the staff to quickly adjust the position of the right crushing roller 102, saving time and effort, and improving work efficiency. Specific embodiment 2

[0038] See also Figure 2 and Figure 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a buffer assembly 4 is provided, the buffer assembly 4 includes a U-shaped frame 401 and a guide rod 402 rotatably connected thereto, and inner buffer springs 404 and outer buffer springs 405 are respectively sleeved on both sides of the outer wall of the guide rod 402, which solves the problem that the existing silage machine crushing roller gap adjustment device plays a buffering role when adjusting the first crushing roller through a single-sided buffer spring during use, and this method is susceptible to the unidirectional force of the buffer spring when the position of the first crushing roller needs to be adjusted outward, causing the first crushing roller and related structures to collide, resulting in damage to the device and affecting the service life.

[0039] Specifically, the other end of the guide rod 402 passes through the through hole on one end surface of the support plate 1023 and is connected to the baffle 403 , the inner buffer spring 404 is located between the U-shaped frame 401 and the inner wall of the support plate 1023 , and the outer buffer spring 405 is located between the outer wall of the support plate 1023 and the baffle 403 .

[0040] Furthermore, the fixed sleeve 1022 is composed of two parts, the upper part is fixed and is movably connected to the lower sleeve ring through a hinge, so when the eccentric shaft 1021 rotates, it will drive the lower part of the fixed sleeve 1022 to rotate synchronously. Under the elastic properties of the inner buffer spring 404 and the outer buffer spring 405, it can play a buffering and protective role and increase the service life.

[0041] The operation process of this embodiment is as follows: when the eccentric shaft 1021 rotates, the fixed sleeve 1022 on its outer wall will be driven to rotate, and the rotation of the fixed sleeve 1022 causes the support plate 1023 on its outer wall to rotate synchronously, and under the action of the U-shaped frame 401 and the hinge, the guide rod 402 follows the movement of the support plate 1023, and pushes the inner buffer spring 404 or the outer buffer spring 405 on the outer wall of the guide rod 402 inward or outward, and the elastic properties of the inner buffer spring 404 or the outer buffer spring 405 can play a buffering role, and can protect the device during the process of adjusting the position of the right crushing roller 102, thereby increasing the service life of the device.
