Description

Technical Field

[0001] The present disclosure relates to the field of agricultural equipment. More specifically, the present disclosure relates to a machine designed to tie a cylindrical bale.

Background Art

[0002] The background description may contain information useful for understanding the present invention. It is not admitted that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Currently available round balers are agricultural machines used to collect straw from the field, then tie the straw with ropes / twines / plastic nets, and finally discharge the straw as a cylindrical bale. The existing mechanism functions by a link mechanism connected to a tailgate indicating that a cylindrical bale has been formed. Further, movement is obtained by pushing the cylindrical bale inside the bailing chamber towards the tailgate, and the swing arm is connected to an end locked by a latch. These mechanisms guide the twine through a specified path, and thus, the end of the twine is sent through the arm. Also, the cut twine is held in a stretched state of about 30 cm so as to catch on the roll bale. The above movement is performed via a link mechanism to release the latch so that the arm falls towards the roll bale inside the bailing chamber. Thereby, the twine catches on the bale and winds the rope around the bale. The rotation of the bale via the twine drives a nylon pulley connected to a worm gearbox mechanism, and the arm distributes the twine over the entire bale by moving along the axis of the bale. Further, in the above-described mechanism used in agricultural machines, a blade for cutting the twine after the cycle is completed is located at the center of the bale, and the operation of the machine continues.

[0004] The above mechanisms and machines are subject to various limitations, such as the complex operation of the machine and the need for skilled labor in the assembly and use of the machine. Due to the complex structure of the machine, the time required to tie the bale is long. In addition, since the swing arm of the mechanical device is exposed, it cannot be protected in terms of safety. Also, due to the problems faced in the use of cheaper plastics or other twines, the operation of the machine is not efficient. Further, when the extended twine is exposed to the wind, it may move from its position. Additionally, the assembly time required for the machine becomes long due to many link mechanisms and mechanisms.

[0005] Therefore, it is necessary to provide a cost-effective and efficient solution that overcomes the above-mentioned drawbacks, limitations, and disadvantages associated with existing bale manufacturing machines and ensures the production of round bales tied with twine so that the maximum speed for tying the twine is achieved. Also, here, the twine starts winding from the center, thereby reducing the possibility of the teeth being properly tied to the round bale and the twine being caught. Further, the above-mentioned machine including pulleys and shafts is easier to use than the worm gear assembly and chain assembly mechanisms that were previously available.

[0006] Objectives of the present disclosure Some of the objectives of the present disclosure that are met by at least one embodiment of the present specification are as listed below in this specification.

[0007] An objective of the present disclosure is to overcome the above-mentioned drawbacks, limitations, and disadvantages associated with existing bale tying machines.

[0011] The object of the present disclosure is to provide a mechanism that enables a machine to function with a minimum number of parts and reduces the time required for assembly.

[0012] The object of the present disclosure is to provide a mechanism that enables a machine to operate in a dusty / windy environment by using a unique cleaning method adapted to clean the twin during operation.

Summary of the Invention

[0015] The present disclosure relates to the field of agricultural equipment. More particularly, the present disclosure relates to a machine designed to tie a cylindrical bale.

Means for Solving the Problems

[0016] The proposed baler can include a chain, a baler frame, and a blade. The chain is configured to be connected to both ends of the link plates of the baler to form a chain drive. The chain drive of the required length is formed using sprockets. The baler frame of the baler is configured to engage with a side backstop device. The side backstop device holds the twine at one end for a predetermined period and feeds out the twine for the next cycle. The feeding out of the twine can also be done using a friction roller connected to an electric / hydraulic motor. The blade is configured to cut the twine when the desired density of the round bale is obtained. The blade is attached under the side backstop device. Further, when the blade cuts the twine, the movement of the twine is stopped and further movement of the baler is prevented.

[0017] The side backstop device may include a catcher body and a lock plate. The catcher body and the lock plate are bolted using a spring-biased pin.

[0018] The twine feeding system for feeding out can include a friction roller and an electric / hydraulic motor for the next cycle.

[0019] The baler can include a lever configured to engage with the side backstop device and push the spring-biased pin to open the lock plate to drop the twine onto the round bale when the bale density of the round bale reaches a predetermined level.

[0020] When the tying of the round bale is completed, the round bale is discharged, and the lever and the side backstop device return to their original positions to hold the twine for the next cycle.

[0021] When the chain reaches the extreme end of the link plate, the lever is released by the backstop device, and the side backstop device is closed to catch and hold the twine.

[0022] The bevel is made of a material selected from the group including steel, iron, and plastic.

[0023] The twine is made of a material selected from the group including nylon material, plastic, alloy, polymer, and metal.

[0024] Therefore, the present disclosure provides a cost-effective and efficient solution in the form of round bale tying. The bevel ensures that the twine is properly wound around the round bale and can operate in windy and dusty environments.

However, the amount of detail provided is not intended to limit the expected variations of the embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternative forms within the spirit and scope of the present disclosure as defined by the appended claims.

[0030] In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent to those skilled in the art that embodiments of the present invention may be practiced without some of these specific details.

[0031] Embodiments of the present disclosure relate to the field of agricultural equipment, and more particularly, to machines designed to bind cylindrical bales.

[0032] According to one aspect, the present disclosure details a baler for using twine to bind round bales. The baler can include a twine payout system using a chain, a baler frame, a side backstop device or friction rollers, and a blade. The chain may be configured to be connected to both ends of the link plate of the baler to form a chain drive. The required length of the chain drive may be formed using sprockets. The baler frame of the baler may be configured to engage with the side backstop device. The side backstop device holds the twine at one end for a predetermined period and pays out the twine for the next cycle. The blade may be configured to cut the twine when the binding of the round bale is completed. The blade may be attached under the side backstop device. Further, when the blade cuts the twine, the movement of the twine is stopped and further movement of the twine holder and the chain is prevented.

[0033] In one embodiment, the side backstop device may include a catcher body and a lock plate. The catcher body and the lock plate are bolted using a spring-biased pin.

[0034] In one embodiment, instead of the side backstop device, a twine payout system using friction rollers and an electric / hydraulic motor.

[0035] In one embodiment, the baler can include a lever configured in the side backstop device and engaged to push a spring-biased pin to open the lock plate and drop the twine onto the round bale when the bale density of the round bale reaches a predetermined level.

[0036] In one embodiment, when the tying of the round bale is completed, the round bale is discharged, and the lever and the side backstop device return to their original positions to hold the twine for the next cycle.

[0037] In one embodiment, when the chain reaches the extreme end of the link plate, the lever is released by the backstop device, and the side backstop device is closed to capture and hold the twine.

[0038] In one embodiment, the bale is made of a material selected from the group including steel, iron, and plastic.

[0039] In one embodiment, the twine is made of a material selected from the group including nylon material, plastic, alloy, polymer, and metal.

[0040] Referring to FIG. 1, an exemplary view of a machine 100 with a proposed bale for tying a round bale according to an embodiment of the present disclosure is shown. This machine with the proposed bale is another variation of the already available machines used for tying bales. With respect to the present disclosure, the proposed bale can operate via mechanical means. The bale can have a chain connected to both ends of the link plate to form a chain drive of the required length using a sprocket. Further, side backstop devices can be attached to both sides of the bale frame to hold the twine at one end for a certain period of time and use it for the next cycle. Instead of the side backstop device, a twine payout system using friction rollers and an electric / hydraulic motor can also be used. The bale may be provided with a blade existing under the side backstop, and the blade may be used to cut the twine when the twine reaches the desired length.

[0041] Referring now to FIG. 2, an exemplary detailed view of the proposed beller 200, according to an embodiment of the present disclosure, is shown. The beller 200 is used to tie a round bale 602 using a twine 604. The beller 200 includes a chain 202 configured to be connected to both ends of a link plate 204 of the beller 200 to form a chain drive 206. The chain drive 206 of the required length is formed using a sprocket 208. The beller 200 includes a beller frame configured to engage with a side backstop device 210. The beller frame holds a twine at one end for use during a predetermined period and the next cycle. Further, the beller 200 includes a blade 212 configured to cut the twine when a desired density of the round bale is obtained. The blade 212 is mounted under the side backstop device 210. Further, when the blade 212 cuts the twine, the movement of the twine is stopped and further movement of the beller 200 is prevented.

[0042] The side backstop device 210 includes a catch body 302 bolted using a spring-biased pin 306 and a lock plate 304. In one embodiment, the beller 200 includes a lever 214 configured to engage with the side backstop device 210 and push the spring-biased pin 306 to open the lock plate 304 to drop the twine 604 onto the round bale 602 when the bale density of the round bale 602 reaches a predetermined level.

[0043] In one embodiment, when the round bale 602 obtains the desired density, the round bale 602 is discharged and the lever 214 and the side backstop device 210 are wound up towards the original position of the round bale 602. In another embodiment, when the chain 202 reaches the extreme end of the link plate 204, the lever 214 is released by the backstop device and the side backstop device is closed to capture and hold the twine 604.

[0044] The beater 200 is made of a material selected from the group including steel, iron, and plastic, and the twin 604 is made of a material selected from the group including nylon material, plastic, alloy, polymer, and metal.

[0045] Referring now to FIG. 3, an exemplary view of a side backstop device according to an embodiment of the present disclosure is shown. The side backstop device 210 includes a catcher body 302 and a lock plate 304. The catcher body 302 and the lock plate 304 are bolted using a spring-biased pin 306 that can be used for locking. When the bale density reaches a desired amount, the lever 214 presses the spring to open the lock plate 304 and drop the twin onto the rotating bale. Further, when the link plate of the chain reaches the end, the lever 214 is released and the side backstop device 210 is closed to capture and hold the twin.

[0046] With respect to FIG. 4, exemplary steps 400 involved in the feed path of the twin during the operation of the beater 200 according to an embodiment of the present disclosure are shown. In step 1, the twin is shown as being input from the outside to the beater 200. In step 2, the twin is sent through a plastic pulley. Further, in step 3, the twin is sent through a roller. Then, in step 4, when the roller of the link plate pulley moves to the center of the bale and the twin for tying the round bale is released, in step 5, the spring latch of the side catcher assembly is actuated.

[0047] FIG. 5 shows an exemplary side view of the machine and operation 500 while using the proposed baler according to one embodiment of the present disclosure. With respect to FIG. 5, a bale density adjustment lever 502, a link mechanism for opening the side catcher lever 504, and a lever for actuating the side catcher lever 506 are shown. When the bale reaches the desired density level, the side catcher lever 504 is pulled, pushing and opening the bale density adjustment lever 502 and the side catcher lever 506 to discharge the round bale.

[0048] FIG. 6 shows an exemplary operation 600 of the proposed baler 200 when the side backstop device 210 is open according to one embodiment of the present disclosure. With respect to FIG. 6, when the side backstop device 210 is open, the twine 604 is forced to drop towards the rotating blade, starting the winding up of the round bale 602.

[0049] Referring to FIGS. 7A - 7B, in one embodiment, when the bale density reaches the desired density, the side backstop device 210 drops the chain onto the rotating bale 602. Further, when the twine 604 catches on the bale 602, the bale 604 starts the rotation of the twine pulley and can feed the twine 604 onto the bale 604.

[0050] Referring to FIG. 8 in an embodiment, a twine feeding system is shown instead of the backstop device to feed the twine for the next cycle.

[0051] As the twine 604 further advances, the carriage moves forward to the center where the twine 604 is cut by the blade 212 and the passage of the twine 604 stops. This stops the further movement of the carriage. Further, when the bale is discharged, the bale density lever can return to its original position, the side backstop can return to its original position, and the cycle is repeated for the next bale. Further, the winding up of the twine starts towards the right side of the bale.

[0052] Accordingly, the present invention overcomes the above-mentioned drawbacks, limitations, and disadvantages associated with existing round bale tying machines, and provides a cost-effective and efficient solution in the form of a baler that guarantees safety and performance with the least possible execution time. Also, the proposed solution is cost-effective and can perform their functions in a dusty environment.
