Description

Technical Field

[0001] The utility model belongs to the field of balers, and particularly relates to a double-cylinder main piston mechanism with a guiding function and a baler. Background Art

[0002] The double-outlet bale press uses two oil cylinders to drive the main piston to move. The two oil cylinder barrels are connected to the main piston in a simple connection manner to lift the main piston. Both ends of the oil cylinder rod are connected to the box body through a fixing frame.

[0003] This structure belongs to a state where the middle movable cylinder barrel is suspended with both ends fixed. This structure will cause certain damage to the oil cylinder. Moreover, when the two oil cylinder barrels drive the main piston to move during the movement of the oil cylinder, the oil cylinder barrel and the rod are in sliding friction. Once there is resistance on one side of the oil cylinder, it will cause the two oil cylinders to be asynchronous, thereby damaging the overall structure. This structure has a high failure rate and high maintenance costs. Content of the Utility Model

[0004] In view of the above problems, the utility model provides a double-cylinder main piston mechanism with a guiding function, which includes a box body. On both sides of the outer wall of the box body, an oil cylinder and a first guiding member are symmetrically arranged. The long side of the box body, the first guiding member and the oil cylinder are parallel to each other. The oil cylinder is connected to the hydraulic system of the baler. The driving oil cylinder output end moves reciprocally along the length of the box body under the guiding action of the first guiding member;

[0005] A piston is arranged in the box body and is parallel to the wide side of the box body. On both side walls of the box body, second guiding members are arranged along the length direction of the box body. Both sides of the piston pass through the second guiding members and are respectively connected to a group of oil cylinder output ends, so that the piston and the second guiding members form a sliding groove guiding fit along the length direction of the box body.

[0006] Preferably, the first guiding member includes two parallel slide rails, and the two ends of the adjacent slide rails are connected through a mounting plate;

[0007] The slide rails are arranged in the middle of the oil cylinder to form the fixed end of the oil cylinder. The output end of the oil cylinder is connected with a guide wheel, and the guide wheel and the slide rail form a guide rail guiding fit.

[0008] Preferably, the oil cylinder is a double-acting oil cylinder, which includes a cross-bar-shaped rod. Both ends of the cross-bar are respectively installed on the mounting plate to form the fixed end of the oil cylinder. An oil cylinder barrel is coaxially sleeved on the rod. The oil cylinder barrel is arranged to slide axially on the rod to form the output end of the oil cylinder. A guide wheel is arranged on the oil cylinder barrel, and the guide wheel and the slide rail form a guide rail guiding fit.

[0009] Preferably, one end of a group of second mounting seats is symmetrically arranged on both sides of the outer barrel wall of the oil cylinder barrel, and the other end of the second mounting seat is connected with the guide wheel, and the guide wheel and the slide rail form a guide rail guiding fit.

[0010] Preferably, the second guiding member is a guiding groove. Two mutually parallel guiding grooves are formed on the side wall of the same box body, and the groove length is parallel to the length direction of the box body. One end of the first mounting seat is symmetrically connected to the middle part of the oil cylinder along the axis. The first mounting seat and the guiding groove form a sliding guiding fit along the groove length direction, and the other end of the first mounting seat is connected to the side wall of the piston.

[0011] Preferably, the guiding groove is a long strip groove, and the first mounting seat is composed of an inverted L-shaped plate. One end of the first mounting seat is connected to the oil cylinder, and the horizontal plate section of the first mounting seat forms a sliding fit with the second guiding member. The other end of the first mounting seat is connected to the side wall of the piston through a piston connecting frame.

[0012] Preferably, a support cross beam is connected inside the box body, and the support cross beam is parallel to the wide side of the box body.

[0013] Preferably, the piston is in the shape of a square plate, and both sides of the piston are attached to both sides of the inner wall of the box body.

[0014] Preferably, the slide rail is a slideway rail.

[0015] The present utility model also claims to protect a baler, which applies the above-mentioned double oil cylinder main piston mechanism with a guiding function. The oil cylinder is connected to the hydraulic system of the baler, converts hydraulic energy into mechanical energy, and provides driving force for the baler.

[0016] Beneficial effects

[0017] The present utility model is mainly reflected in two aspects. First, a first guiding member is provided to guide the operation of the output end of the oil cylinder. Second, a second guiding member is provided to guide the operation path of the piston. Also, since the piston is perpendicular to a group of oil cylinders to form an I-shaped structure, it means that the guiding effects of the two aspects complement each other, and the piston cannot be deflected during operation. Finally, it achieves the effect of double ensuring that a group of oil cylinders operate synchronously, which can well reduce the damage to the overall device caused by the non-synchronization of the two-side oil cylinders in the prior art, reduce the after-sales cost, and improve the operation efficiency of the baler, which is very ingenious.

[0018] Moreover, the guide wheel can play a supporting role for the oil cylinder. It can be understood that when the oil cylinder moves reciprocally, it is no longer in a suspended state. Therefore, the oil cylinder can be well protected, and the service life of the oil cylinder can be effectively extended.

[0019] Furthermore, compared with the prior art, the present application can, while ensuring the integrity of the existing box body, realize the connection between the piston and the oil cylinder and well guide the piston only by opening the second guiding member and the first mounting seat, which can be said to kill two birds with one stone.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] Refer to Figure 1 , Figure 1Shows a schematic diagram of a double-cylinder main piston mechanism with a guiding function; in this schematic diagram, a double-cylinder main piston mechanism with a guiding function includes a box body 1. On both sides of the outer wall of the box body 1, a cylinder 2 and a first guiding member 3 are symmetrically arranged. The long side of the box body 1, the first guiding member 3, and the cylinder 2 are parallel to each other. The cylinder 2 is connected to the hydraulic system of the baler. Driven by the guiding action of the first guiding member 3 at the output end of the cylinder 2, a reciprocating movement is generated along the length of the box body 1.

[0033] A piston 4 is arranged inside the box body 1, and the piston 4 is parallel to the wide side of the box body 1. The piston 4 is in the shape of a square plate, and both sides of the piston 4 are in contact with both sides of the inner wall of the box body 1. Second guiding members 5 are arranged on both side walls of the box body 1 along the length direction of the box body 1. Both sides of the piston 4 pass through the second guiding members 5 and are respectively connected to the output ends of a group of cylinders 2, so that the piston 4 and the second guiding members 5 form a sliding groove guiding fit along the length direction of the box body 1.

[0034] The main body of the present utility model is reflected in two aspects. First, the first guiding member 3 is provided to guide the operation of the output end of the cylinder. Second, the second guiding member 5 is provided to guide the running path of the piston 4. Also, since the piston 4 is perpendicular to a group of cylinders 2 to form an I-shaped structure, it means that the guiding effects of the two aspects complement each other, and the piston 4 cannot deflect during the operation process. Eventually, it has the effect of double ensuring that a group of cylinders 2 run synchronously, which can well reduce the damage to the overall device caused by the asynchronous operation of the two side cylinders 2 in the prior art, reduce the after-sales cost, and improve the operation efficiency of the baler, which is very ingenious.

[0035] Reference Figure 2 , Figure 2 Shows a front view of a double-cylinder main piston mechanism with a guiding function; it can be clearly seen from this schematic diagram that the first guiding member 3 includes two parallel slide rails 31, and the two ends of the adjacent slide rails 31 are connected by mounting plates 32.

[0036] The slide rails 31 are arranged in the middle of the cylinder 2 to form the fixed end of the cylinder 2. The output end of the cylinder 2 is connected to a guide wheel 33, and the guide wheel 33 and the slide rails 31 form a guide rail guiding fit.

[0037] The cylinder 2 is a double-acting cylinder, including a cross-bar-shaped cylinder rod 20. The two ends of the cross-bar are respectively installed on the mounting plates 32 to form the fixed end of the cylinder 2. An oil cylinder 21 is coaxially sleeved on the cylinder rod 20. The oil cylinder 21 is arranged to slide axially on the cylinder rod 20 to form the output end of the cylinder 2. A guide wheel 33 is arranged on the oil cylinder 21, and the guide wheel 33 and the slide rails 31 form a guide rail guiding fit.

[0038] One end of a group of second mounting seats 210 is symmetrically arranged on both sides of the outer cylinder wall of the oil cylinder 21, and the other end of the second mounting seat 210 is connected to the guide wheel 33. The guide wheel 33 and the slide rails 31 form a guide rail guiding fit.

[0039] It is worth mentioning here that the guide wheel 33 can play a supporting role for the oil cylinder 21. It can be understood that when the oil cylinder 21 moves reciprocally, it is no longer in a suspended state. Therefore, the oil cylinder 2 can be well protected, effectively extending the service life of the oil cylinder.

[0040] Reference Figure 3 , Figure 3 shows Figure 1 a partially enlarged schematic view; it can be clearly seen from this schematic view that the second guide member 5 is a guide groove. Two mutually parallel guide grooves are provided on the side wall of the same box body 1, and the groove length is parallel to the length direction of the box body 1. One end of the middle part of the oil cylinder 21 is symmetrically connected to one end of the first mounting seat 211 along the axis. The first mounting seat 211 and the guide groove form a sliding groove guiding fit along the groove length direction, and the other end of the first mounting seat 211 is connected to the side wall of the piston 4.

One end of the first mounting seat 211 is connected to the oil cylinder 21, and the horizontal plate section of the first mounting seat 211 forms a sliding fit with the long strip groove. The other end of the first mounting seat 211 is connected to the side wall of the piston 4 through a piston connecting frame.

[0042] It is worth mentioning here that compared with the prior art, in the case of ensuring the integrity of the existing box body 1, only by opening a long strip groove and using the first mounting seat 211, the connection between the piston 4 and the oil cylinder 21 can be realized, and the piston 4 can be well guided, which can be said to kill two birds with one stone.

[0043] A support cross beam 11 is installed on the inner wall of the box body 1. The support cross beam 11 is parallel to the wide side of the box body 1. The support cross beam 11 can prevent the box body 1 from deforming during work.
