Description

Technical Field

[0001] This invention relates to baling machines, and more specifically to a double-compartment baling machine with combined compartments. Background Technology

[0002] Large towed balers have high baling efficiency, but require tools such as forks and cannot produce small square bales. While small towed balers can meet the requirement of producing small square bales, their efficiency is relatively low. Dual-compartment balers can solve the above problems. Dual-compartment balers are devices that can bale straw, hay, etc. and form two square bales at the same time. Since most existing dual-compartment balers are modified from single-compartment balers, they have problems such as poor compartment cutting effect, unstable transmission, or unreasonable transmission. In response to some of the problems existing in current dual-compartment balers, the applicant has developed a dual-compartment baler with combined compartments. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a dual-compartment baler with combined compartments. By optimizing and adjusting the straw box, knotting mechanism, baling needle structure and transmission structure, a dual-compartment baler with better performance is formed.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a double-compartment baler of the combined compartment type, including a straw box, a picking mechanism, a feeding mechanism, a knotting mechanism and a baling needle structure. A straw inlet box is provided below the straw box. The picking mechanism is connected to the straw inlet box. The feeding mechanism is set in the straw inlet box and feeds the straw picked up by the picking mechanism into the straw box. The knotting mechanism is set on the straw box and includes a first knotter and a second knotter. The first knotter and the second knotter are symmetrically distributed on the left and right. The hay box has a piston movement channel. A dual-output gearbox is located at the front end of the piston movement channel within the hay box. A first transmission assembly and a second transmission assembly are located on the left and right sides of the gearbox, respectively. The first transmission assembly includes a first drive shaft and a first crankshaft. The first drive shaft is connected to the hay box and rotates relative to it. One power output unit of the gearbox is connected to the first drive shaft via the first crankshaft and transmits power to the first drive shaft.

The track assembly is connected to the mounting frame and is located between the two tying needle assemblies, with tying needle tracks provided at each tying needle assembly.

[0005] By setting a vertical cutting blade at the end of the hay bale box, which works in conjunction with the vertical cutting blade on the pressing piston, the hay can be cut more effectively. For the purpose of double-compartment baling, each pressing section is equipped with a knotter and baling needle assembly, and power is transmitted from both sides of the hay bale box through a double-sided transmission structure, making the structure more reasonable.

[0006] As an optional technical solution of the present invention, the vertical cutting blade is set in the middle of the straw pressing inlet and divides the straw pressing inlet into two sub-inlets of the same size.

At least one baling needle is provided on the horizontal tube between the roller and the swing arm. The power receiving part of each knotter extends to the outside of the hay box and is provided with a crank connecting rod. The crank connecting rod is connected to the swing arm of the corresponding side baling assembly and transmits power to the corresponding side baling needle assembly.

[0009] As an optional technical solution of the present invention, a first knotting transmission part and a picking transmission part are provided on the outside of the hay box on the first transmission shaft. The first knotting transmission part is connected to the power receiving part of the first knotter and transmits power to the first knotter. The picking transmission part is connected to the power receiving part of the picking mechanism and transmits power to the picking mechanism. A feeding transmission part is provided on the outside of the hay box on the second transmission shaft. The feeding transmission part is connected to the shift fork shaft of the feeding mechanism and transmits power to the shift fork shaft. A second knotting transmission part is provided on the shift fork shaft. The second knotting transmission part is connected to the power receiving part of the second knotter and transmits power to the second knotter.

[0010] As an optional technical solution of the present invention, the power receiving part of each knotter, the first knotting transmission part, the picking transmission part, and the power receiving part of the picking mechanism are transmission sprockets, and the first knotting transmission part and the power receiving part of the first knotter are connected by transmission chains, and the picking transmission part and the power receiving part of the picking mechanism are connected by transmission chains. The feed mechanism has a drive sprocket on its shift fork shaft. The feed drive and the second knotting drive are drive sprockets. The feed drive and the drive sprocket on the shift fork shaft, and the second knotting drive and the power receiving part of the second knotter are connected by a drive chain.

[0011] As an optional technical solution of the present invention, the roller is a deep groove ball bearing, which is installed on the horizontal tube and located in the track groove.

[0012] As an optional technical solution of the present invention, at least two first waist holes are provided on the left and right end faces of the mounting base, and a second waist hole is provided on the track plate corresponding to each of the first mounting holes. The track plate is installed on the mounting base by bolts passing through the first waist holes and the second waist holes.

[0013] As an optional technical solution of the present invention, the mounting frame includes an upper reinforcing rib, a lower reinforcing rib, and side reinforcing ribs. The upper and lower reinforcing ribs are located above and below the end of the piston moving channel, respectively, and both the upper and lower reinforcing ribs are connected to the hay box. There are two side reinforcing ribs, and each side reinforcing rib is connected to the upper and lower reinforcing ribs. The area enclosed by the upper reinforcing rib, the lower reinforcing rib, and the two side reinforcing ribs is the hay pressing inlet. A blade holder is provided inside the hay box below the piston moving channel. The blade holder is connected to the lower reinforcing rib. A horizontal cutting fixed blade is provided on the blade holder, and a vertical cutting fixed blade is connected to the upper reinforcing rib and the blade holder.

[0014] As an optional technical solution of the present invention, a density adjustment chamber connecting frame is also provided on the mounting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the double-compartment baler of the present invention, two separate inlets are formed between the straw box and the density adjustment chamber by a vertical cutting blade. During the straw pressing and baling process, the straw is pressed into the density adjustment chamber from the two separate inlets. With the help of the knotter and baling needle assembly, the straw is baled in separate compartments. The double-sided transmission structure adopted in the present invention transmits the power of the gearbox from both sides of the straw box to the designated components. The transmission structure is more reasonable and can be well adapted to the double-compartment baler with double knotter and double baling needle assembly of the present invention. 2. Vertical and horizontal fixed blades are installed at the end of the piston movement channel on the hay bale box. Vertical and horizontal moving blades are installed on the pressing piston. As the pressing piston moves to the pressing position, it squeezes the hay in the piston movement channel toward the pressing inlet. The hay comes into contact with the vertical fixed blade and is cut off, then enters the two separate inlets. When the pressing piston moves to the pressing position, the horizontal fixed blade and the horizontal moving blade completely cut off the hay in the hay bale box and the hay that has not entered the hay bale box. The vertical moving blade and the vertical fixed blade work together to completely cut off the hay in the hay bale box, so as to avoid the hay entering the pressing chamber without being completely cut off, which would affect the baling effect. 3. The baling needle structure is particularly suitable for the bin-type baler of this application. The track assembly is installed on the straw box and located between the two baling needle assemblies. It can not only support and guide the two baling needle assemblies, but also does not affect the power transmission between the two baling needle assemblies and the gearbox.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figures 1-7 As shown, a dual-compartment baler includes a straw box 1, a picking mechanism 2, a feeding mechanism 3, a knotting mechanism 4, a baling needle mechanism, a density adjustment chamber 7, and other essential structures required for a baler. The straw box 1 is the structure used in existing balers. The straw box 1 is equipped with a wheel structure and a traction frame. A straw inlet box 6 is located below the straw box 1. The straw inlet end of the straw inlet box 6 is equipped with a picking mechanism 2. The feeding mechanism 3 is located inside the straw inlet box 6. After the picking mechanism 2 picks up the straw and throws it into the straw inlet box 6, the feeding mechanism 3 feeds the straw picked up and thrown by the picking mechanism 2 into the straw box 1 for operations such as pressing and baling. The straw inlet box 6, the picking mechanism 2, and the feeding mechanism 3 are all related structures used in existing balers and are mature technologies. The structural features of these components will not be described in detail in this application.

[0020] The straw box 1 is equipped with a piston movement channel defined by a guide groove or guide rail. A straw-pressing piston 104 is installed inside the straw box 1, capable of reciprocating along the piston movement channel. A mounting frame 105 is provided at the rear end of the piston movement channel on the straw box 1. The mounting frame 105 has a straw-pressing inlet, which is directly opposite and communicates with the piston movement channel. A vertical cutting blade 106 is installed on the mounting frame 105, vertically positioned at the straw-pressing inlet and dividing it into two sub-inlets. A knotting mechanism 4 is installed on the straw box 1, including a first knotter 401 and a second knotter 402. The two knotters are symmetrically distributed left and right and correspond to the positions of the two sub-inlets respectively. The straw-pressing piston 104 and the knotters are related structures used in existing balers, and their structures will not be described in detail in this application.

[0021] The straw box 1 has an equipment cavity at the front end of the piston movement channel. A gearbox 101 is housed within the equipment cavity. The gearbox 101 is a double-output shaft gearbox 101, with its power input extending from the front end of the straw box 1 and connected to the flywheel of the baler. A first transmission assembly 102 and a second transmission assembly 103 are respectively located on the left and right sides of the gearbox 101. The first rotating assembly includes a first drive shaft and a first crankshaft. The first drive shaft is mounted on the straw box 1 via a bearing housing and is capable of rotating relative to the straw box 1. The first crankshaft is located within the gearbox 102. The gearbox 101 transmits power to the first drive shaft via the first crankshaft. The first drive shaft is provided with a first knotting transmission part 110 and a picking transmission part 111 on the outside of the hay box 1. The first knotting transmission part 110 is connected to the power receiving part of the first knotter 401 and transmits the power of the first drive shaft to the first knotter 401. The picking transmission part 111 is connected to the power receiving part of the picking mechanism 2. The first drive shaft transmits power to the first knotter 401 and also transmits power to the picking mechanism 2.

[0022] The power receiving part of the first knotter 401, the first knotting transmission part 110, the pickup transmission part 111, and the power receiving part of the pickup mechanism 2 are all transmission sprockets. The first knotting transmission part 110 and the power receiving part of the first knotter 401 are connected by a transmission chain, and the pickup transmission part 111 and the power receiving part of the pickup mechanism 2 are connected by a transmission chain.

[0023] The second transmission assembly 103 includes a second drive shaft and a second crankshaft. Similar to the first transmission assembly 102, the second drive shaft is mounted on the hay box 1 via a bearing housing. The second drive shaft is coaxial with the power output section on the corresponding side of the gearbox 101 and can rotate relative to the hay box 1. The second crankshaft is located between the second drive shaft and the gearbox 101 and is connected to the second drive shaft and another power output section of the gearbox 101. The gearbox 101 transmits power to the second drive shaft via the second crankshaft. The second drive shaft is mounted on the hay box 1. An external feeding transmission unit 112 is provided. The fork shaft of the feeding mechanism 3 extends out of the grass box 6 and is connected to the feeding transmission unit 112. The second transmission shaft can transmit power to the feeding mechanism 3. A second knotting transmission unit 113 is also provided on the fork shaft outside the grass box 6. The second knotting transmission unit 113 is connected to the power receiving part of the second knotter 402 and transmits power to the second knotter 402. While the second transmission shaft transmits power to the fork shaft and drives the fork shaft to rotate, the fork shaft transmits power to the second knotter 402.

[0024] The power receiving part, the feeding transmission part 112, and the second knotting transmission part 113 of the second knotter 402 are all transmission sprockets. A transmission sprocket is also provided on the shift fork shaft at a position suitable for transmission connection with the feeding transmission part 112. The feeding transmission part 112 and the transmission sprocket on the shift fork shaft are connected by a transmission chain. The second knotting transmission part 113 and the power receiving part of the second knotter 402 are connected by a transmission chain.

[0025] A crank connecting rod 403 is also provided on the mounting wheel axle of the power receiving part of the first knotter 401 and the mounting wheel axle of the power receiving part of the second knotter 402. The crank connecting rod 403 is used to connect the bundling needle structure 5 so as to transmit the power of the gearbox 101 to the bundling needle structure 5.

[0026] The tying needle structure 5 includes a track assembly and two tying needle assemblies. The tying needle assemblies are located at the rear end of the piston movement channel. The two tying needle assemblies are located on the left and right sides of the track assembly and correspond to the two sub-inlet positions respectively. The track assembly is connected to the mounting frame 105. The track assembly is located between the two tying needle assemblies, and tying needle tracks are provided at each tying needle assembly position.

[0027] Specifically, the track assembly includes a mounting base, track plates 501, and rollers. The mounting base is connected to the mounting frame 105 and is located below the straw pressing inlet. Two track plates 501 are provided on the mounting base, and the two track plates 501 are symmetrically distributed at the left and right ends of the mounting base. Each track plate 501 is provided with a track groove, which is the baling needle track used to limit the movement trajectory of the baling needle assembly. Rollers are provided in the track grooves. The rollers cooperate with the track grooves and can move along the direction defined by the track grooves. The rollers can be deep groove ball bearings or other types of roller structures.

[0028] The track groove is an arc-shaped groove adapted to the swing trajectory of the bundling needle assembly, and the end of the track groove is set to an arc-shaped end face adapted to the shape of the outer end face of the roller. At least two first waist holes are provided on both the left and right end faces of the mounting base for mounting the track plate 501. At least two second waist holes are provided on the track plate 501, and the spacing between the second waist holes is adapted to the spacing between the first waist holes, so that when the track plate 501 is fitted against the end face of the mounting base, the positions of each second waist hole match those of each first waist hole. The track plate 501 can be mounted onto the mounting base by using bolts passing through the first waist holes and corresponding second waist holes and connecting them to the mounting base. The holes provided on the mounting base and the track plate 501 are all waist holes, allowing for fine-tuning of the position of the track plate 501 relative to the mounting base.

[0029] As an optional implementation, the length direction of the first waist hole is perpendicular to the length direction of the corresponding second waist hole, so as to fix the position of the track plate 501.

[0030] Baling needle assemblies are provided on both the left and right sides of the track assembly. The two sets of baling needle assemblies are symmetrically distributed. The baling needle assembly includes a horizontal tube 502, a swing arm 503, and a baling needle 504. The horizontal tube 502 is horizontally placed. One end of the horizontal tube 502 is connected to a roller, which can rotate relative to the horizontal tube 502. The other end of the horizontal tube 502 is provided with a swing arm 503. In the left and right direction, the swing arm 503 is located outside the hay box 1. The swing arm 503 is connected to a crank connecting rod 403 located on the same side of the hay box 1. At least one baling needle 504 is provided on the horizontal tube 502 between the roller and the swing arm 503. The baling needle 504 adopts the baling needle structure 5 in the prior art baling machine. The structure of the baling needle will not be described in detail in this application.

[0031] The baler of this application adopts a double-sided transmission method. The gearbox 101 transmits power from one side of the straw box 1 to the first knotter 401, the picking mechanism 2 and a baling needle assembly through the first transmission assembly 102, and transmits power from the other side of the straw box 1 to the second knotter 402, the feeding mechanism 3 and another baling needle assembly through the second transmission assembly 103. The power transmission effect is good and more stable, and it can adapt to the structural layout of double knotters and double baling needle assemblies.

[0032] The first crankshaft and the second crankshaft have the same deflection angle in the circumferential direction. Both the first crankshaft and the second crankshaft are hinged with connecting rods, and each connecting rod is hinged with the grass-pressing piston 104. The gearbox 101 can drive the grass-pressing piston 104 to move back and forth between the grass-pressing position and the grass-feeding position along the piston movement channel through the first crankshaft and the second crankshaft.

[0033] The vertical cutting blade 106 is positioned at the center of the straw-pressing inlet, dividing it into two equal-sized sub-inlets. A horizontal cutting blade 109 is positioned at the lower edge of each sub-inlet on the mounting frame 105. Both the vertical cutting blade 106 and the horizontal cutting blade 109 face the straw-pressing piston 104. A vertical cutting blade 107 and a horizontal cutting blade 108 are positioned on the end face of the straw-pressing piston 104 facing the mounting frame 105. The vertical cutting blade 107 is vertically positioned and corresponds to the position of the vertical cutting blade 106. The horizontal cutting blades 108 are horizontally positioned... The positions of the pressing piston 104 and the horizontal cutting fixed blades 109 are set and correspond to the positions of the horizontal cutting fixed blades 109 respectively. When the pressing piston 104 moves from the grass inlet to the pressing position, it cuts the grass and straw across the two inlets by squeezing. When the pressing piston 104 moves to the pressing position, the vertical cutting moving blade 107 and the vertical cutting fixed blade 106 cooperate to completely cut the straw and grass, avoiding the situation where the ends of the square bales are not completely cut off. When the pressing piston 104 moves to the pressing position, the horizontal cutting moving blades 108 and the horizontal cutting fixed blades 109 cooperate to completely cut off the grass and straw pressed into the pressing chamber from the external part.

[0034] Specifically, the pressing chamber mounting frame 105 includes an upper reinforcing rib, a lower reinforcing rib, and two side reinforcing ribs. The upper and lower reinforcing ribs are connected to the hay box 1. The upper reinforcing rib is above the end of the piston movement channel, and the lower reinforcing rib is below the end of the piston movement channel. The upper and lower reinforcing ribs are connected by two side reinforcing ribs, which are located on both sides of the end of the piston movement channel. The pressing inlet is the area enclosed by the upper, lower, and side reinforcing ribs. A blade holder is provided inside the hay box 1 below the piston movement channel. The blade holder is connected to the lower reinforcing rib. A horizontal cutting blade 109 is provided on the blade holder. The upper end of the vertical cutting blade 106 is connected to the upper reinforcing rib, and the lower end is connected to the blade holder.

[0035] The mounting frame 105 is also equipped with a density adjustment chamber 7 connecting frame. The density adjustment chamber 7 connecting frame is located on the side of the straw pressing chamber mounting frame 105 away from the straw pressing piston 104, and is used to connect with the density adjustment chamber 7 to realize the installation connection of the density adjustment chamber 7. The straw pressing inlet serves not only as the outlet of the straw box 1, but also as the inlet of the straw pressing chamber of the density adjustment chamber 7. By forming two separate inlets between the straw box 1 and the density adjustment chamber 7 through the vertical cutting blade 106, the problems of separate baling and straw cutting can be solved with minimal modification to the technically mature components such as the straw box 1 and the density adjustment chamber 7. During the straw pressing and baling process, the straw pressing piston 104 presses the straw and causes the straw to enter the density adjustment chamber 7 through the separate inlets. The density adjustment chamber 7 should be equipped with a partition, and the partition should correspond to the position of the vertical cutting blade 107.

[0036] The dual-compartment baler of the present invention has a vertical cutting blade 106 at the end of the straw box 1. The vertical cutting blade 106 cooperates with the vertical cutting blade 106 on the straw pressing piston 104 to cut the straw during pressing, resulting in better straw cutting effect. The two parts of straw after cutting are respectively used by the knotters and baling needle assemblies configured in the corresponding inlets to achieve small bundle packaging and double bundle discharge. In addition, for the purpose of double bundle packaging and discharge, the equipment adopts a more reasonable double-sided transmission structure, which makes the transmission more stable and reasonable, and is suitable for driving the two knotters and the two sets of baling needle assemblies separately.
