Description

Technical Field

[0001] The present disclosure relates to the field of agricultural equipment. More specifically, the present disclosure relates to a machine designed for tying cylindrical bales. Background Art

[0002] The Background Description includes information that may be useful in understanding the present invention. It is not an admission 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] The currently available round balers are agricultural machines for collecting straw from the field, then tying the straw with ropes / cords / plastic nets, and finally discharging the straw in cylindrical bales. The existing mechanism works by a connecting rod connected to the tailgate, which indicates that the cylindrical bale has been formed. In addition, the movement is obtained by pushing the cylindrical bale in the baling chamber toward the tailgate, and the swing arm is connected at the end locked by the latch. These mechanisms make the cord pass through a specific path, and thus the end of the cord passes through the arm. Moreover, the cut cord is kept with an extended length of about 30 cm so that it is captured by the rolling bale. The above movement releases the latch through the connecting rod, so that the arm falls toward the bale rolling in the baling chamber. Therefore, the cord is captured by the bale and it winds the cord to the bale. The bale is connected to the nylon pulley of the worm gear mechanism by the rotation drive of the cord, and the arm distributes the cord over the entire bale by moving along the axis of the bale. Additionally, in the above mechanism used in agricultural machines, the blade is located in the center of the bale, which cuts the string after completing the cycle and the work of the machine continues.

[0004] The above mechanisms and machines are subject to various limitations, such as the operation of the machines is complicated and skilled workers are required to assemble and use the machines. Due to the complex structure of the machine, the time required to tie the bales is long. In addition, the swing arm of the machine is exposed and therefore cannot be protected in terms of safety. Moreover, the operation of the machine is not efficient due to the challenges faced in using cheaper plastic or other ropes. Moreover, the extended ropes sometimes deviate from their positions when exposed to wind. In addition, due to the many links and mechanisms, the assembly time required for the machine is more.

[0005] Therefore, there is a need to overcome the above mentioned drawbacks, limitations and deficiencies associated with the existing bale producing machines and to provide a cost effective and efficient solution which ensures the production of round bales tied with a string such that the maximum speed for the tying string is achieved. Moreover, the string is now wound from the center so that the end is properly tied to the round bale and the chances of the string getting tangled are reduced. Moreover, the mentioned machine including the pulley and shaft is simpler to use than using the earlier available worm gear assembly and chain assembly mechanism.

[0006] Purpose of the invention

[0007] Some of the objectives met by at least one embodiment herein of the present disclosure are listed below.

[0008] An object of the present disclosure is to overcome the above-mentioned shortcomings, limitations and deficiencies associated with existing baling machines.

[0009] It is an object of the present disclosure to provide a compact mechanism to be implemented on a baler which involves as few moving parts as possible.

[0010] An object of the present disclosure is to provide a mechanism to be implemented on a baler such that the machine is not exposed in terms of safety.

[0011] An object of the present disclosure is to provide a mechanism such that the machine can handle all strings / cords including plastic ones.

[0012] An object of the present disclosure is to provide a mechanism that allows the machine to function with a minimum number of parts and a reduced time required for assembly.

[0013] It is an object of the present disclosure to provide a mechanism that enables the machine to perform in dusty / windy environments by using a unique cleaning method that is also suitable for cleaning the cords while working.

[0014] An object of the present disclosure is to provide a mechanism that enables a machine to tie a bale from the center of the bale so that the ends are properly tied to the round bale.

[0015] An object of the present disclosure is to provide a machine utilizing a pulley and shaft mechanism that is easy to form in one piece and is a cost effective solution. Summary of the invention

[0016] The present disclosure relates to the field of agricultural equipment. More specifically, the present disclosure relates to a machine designed for tying cylindrical bales.

[0017] The proposed baler may include a chain, a baler frame and a blade. The chain is configured to be connected at both ends of a connecting plate of the baler to form a chain drive. A chain drive of a desired length is formed using a sprocket. The baler frame of the baler is configured to engage with a side check. The side check holds the string at one end for a predetermined period of time and feeds the string for the next cycle. Feeding the string may also be accomplished using a friction roller connected to an electric / hydraulic motor. The blade is configured to cut the string when a round bale of a desired density is obtained. The blade is attached below the side check. In addition, when the blade cuts the string, the movement of the string stops and further movement of the baler is prevented.

[0018] The side check device may include a catch body and a locking plate. The catch body and the locking plate are bolted together using a spring-loaded pin.

[0019] For feeding the wire, the wire feeding system may include friction rollers and electric / hydraulic motors for the next cycle.

[0020] The baler may include a lever configured to engage the side check device to push the spring loaded pin and open the locking plate to allow the string to drop to the round bale when the bale density of the round bale reaches a predetermined level.

[0021] When the round bale tying is completed, the round bale is ejected and the bars and side check devices reach the initial position to hold the string for the next cycle.

[0022] When the chain reaches the end of the connecting plate, the lever is released by the backstop and the side backstops close to capture and hold the line.

[0023] The baler is made of a material selected from the group consisting of steel, iron and plastic.

[0024] The string is made of a material selected from the group consisting of nylon materials, plastics, alloys, polymers and metals.

[0025] Thus, the present disclosure provides a cost effective and efficient solution to tying round bales. The baler ensures that the string is properly wound on the round bale and is able to work in windy and dusty environments.

[0037] The following is a detailed description of the embodiments of the present disclosure depicted in the accompanying drawings. These embodiments are so detailed as to clearly convey the present disclosure. However, the amount of detail provided is not intended to limit the expected variations of the embodiments; on the contrary, the present invention will cover all modifications, equivalents and substitutes that fall within the spirit and scope of the present disclosure defined by the appended claims.

[0038] 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 the embodiments.

[0039] Embodiments of the present disclosure relate to the field of agricultural equipment and, more particularly, to a machine designed for tying cylindrical bales.

[0040] According to one aspect, the present disclosure sets forth a baler for tying round bales using a string. The baler may include a chain, a baler frame, and a side check or a string supply system using a friction roller and a blade. The chain may be configured to be connected at both ends of a link plate of the baler to form a chain drive. A chain drive of a desired length may be formed using a sprocket. The baler frame of the baler may be configured to engage with a side check. The side check holds the string at one end for a predetermined period of time and supplies the string for the next cycle. The blade may be configured to cut the string when tying of the round bale is completed. The blade may be attached below the side check. In addition, when the blade cuts the string, the movement of the string may stop and prevent further movement of the string retainer and the chain.

[0041] In one embodiment, the side check device may include a catch body and a locking plate. The catch body and the locking plate are bolted together using a spring loaded pin.

[0042] In one embodiment, instead of side checks, the line feeding system utilizes friction rollers and electric / hydraulic motors.

[0043] In one embodiment, the baler may include a lever configured to engage the side check device to push the spring loaded pin and open the locking plate to allow the string to drop to the round bale when the bale density of the round bale reaches a predetermined level.

[0044] In one embodiment, when the round bale is tied, the round bale is ejected and the bars and side check devices reach the initial position to hold the lines for the next cycle.

[0045] In one embodiment, when the chain reaches the end of the connecting plate, the lever is released by the backstop and the side backstops close to capture and hold the line.

[0046] In one embodiment, the baler is made of a material selected from the group consisting of steel, iron and plastic.

[0047] In one embodiment, the string is made of a material selected from the group consisting of nylon materials, plastics, alloys, polymers and metals.

[0048] refer to Figure 1, shows an exemplary view 100 of a machine including a lifting baler for tying round bales according to an embodiment of the present disclosure. Such a machine including a lifting baler is another variant of an already available machine for tying bales. With respect to the present disclosure, the lifting baler can be operated via mechanical means. The baler can have a chain connected to connecting plates at both ends to form a chain drive of the desired length using sprockets. In addition, side check devices can be assembled to the baler frame on either side to hold the cord at one end for a certain period of time and for the next cycle. Instead of the side check devices, a cord feeding system using friction rollers and electric / hydraulic motors can also be used. The baler can be equipped with a blade present below the side check devices, and the blade can be used to cut the cord when the desired length of the cord is reached.

[0049] Reference now Figure 2 , shows an exemplary detailed view of the proposed baler 200 according to an embodiment of the present disclosure. The baler 200 is used to tie a round bale 602 using a string 604. The baler 200 includes a chain 202 configured to be connected at both ends of a connecting plate 204 of the baler 200 to form a chain transmission 206. The chain transmission 206 of a desired length is formed using a sprocket 208. The baler 200 includes a baler frame configured to engage with a side check device 210. The baler frame holds the string at one end for a predetermined period of time and is used during the next cycle. In addition, the baler 200 includes a blade 212 configured to cut the string when a round bale of a desired density is obtained. The blade 212 is attached below the side check device 210. In addition, the movement of the string stops when the blade 212 cuts the string, and further movement of the baler 200 is prevented.

[0050] The side check device 210 includes a catcher body 302 and a locking plate 304 bolted together with a spring loaded pin 306. In one embodiment, the baler 200 includes a lever 214 configured to engage the side check device 210 to push the spring loaded pin 306 and open the locking plate 304 to allow the string 604 to drop to the round bale 602 when the bale density of the round bale 602 reaches a predetermined level.

[0051] In one embodiment, when the round bale 602 achieves the desired density, the round bale 602 is discharged and the rod 214 and the side check devices 210 are wound toward the initial position of the round bale 602. In another embodiment, when the chain 202 reaches the end of the connecting plate 204, the rod 214 is released by the check devices and the side check devices are closed to capture and hold the line 604.

[0052] The baler 200 is made of a material selected from the group consisting of steel, iron, and plastic, and the string 604 is made of a material selected from the group consisting of nylon material, plastic, alloy, polymer, and metal.

[0053] Reference now Figure 3 , an exemplary view of a side check device is shown according to an embodiment of the present disclosure. The side check device 210 includes a catch body 302 and a locking plate 304. The catch body 302 and the locking plate 304 are bolted with a spring-loaded pin 306 that can be used for locking. When the bale density reaches the desired amount, the lever 214 pushes the spring and opens the locking plate 304 to allow the line to fall to the rotating bale. In addition, when the connecting plate of the chain reaches the end, the lever 214 is released and the side check device 210 closes to capture and hold the line.

[0054] refer to Figure 4 , shows exemplary steps 400 involved in the routing of a string during operation of a baler 200 according to an embodiment of the present disclosure. In step 1, the string is shown as being input to the baler 200 from the outside. In step 2, the string is passed through a plastic pulley. Further, in step 3, the string is passed through a roller. Thereafter, in step 4, the rollers of the connecting plate pulley are moved to the center of the bale, and in step 5, the spring latches of the side catcher assemblies are activated when releasing the string to tie a round bale.

[0055] Figure 5 An exemplary side view of a machine and operation 500 when using a raised baler according to an embodiment of the present disclosure is shown. Figure 5 , showing a bale density adjustment bar 502, a link for opening the side catch bar 504, and a bar for actuating the side catch bar 506. When the bale reaches the desired density level, the side catch bar 504 is pulled, and the bale density adjustment bar 502 and the side catch bar 506 are pushed to open and eject the round bale.

[0056] Figure 6 FIG. 6 shows an exemplary operation 600 of the lifting baler 200 when the side check device 210 is open according to an embodiment of the present disclosure. Figure 6 , when the side check devices 210 are opened, the line 604 is forced to fall towards the rotating blade and begins to wrap around the round bale 602.

[0057] refer to FIG. 7A to FIG. 7B In one implementation, when the bale density reaches the desired density, the side check device 210 causes the chain to drop to the rotating bale 602. In addition, when the wire 604 is captured by the bale 602, the bale 604 may begin to rotate the wire pulley and feed the wire 604 to the bale 604.

[0058] refer to Figure 8 In one implementation, a wire feeding system is shown instead of a non-return device to feed wire for the next cycle.

[0059] As the cord 604 advances further, the carriage is advanced to the center where the cord 604 is cut by the blade 212 and the driving of the cord 604 through is stopped. This will stop the carriage from moving further. Furthermore, when the bale is ejected, the bale density bar can return to its initial position and the side check device can return to its initial position and the cycle is repeated for the next bale. Additionally, the winding of the cord begins towards the right side of the bale.

[0060] The present invention thus overcomes the above-mentioned drawbacks, limitations and deficiencies associated with existing round bale tying machines and provides a cost-effective and efficient solution in the form of a proposed baler that ensures safety and performance in the shortest possible execution time. Furthermore, the proposed solution is cost-effective and can perform its function in dusty environments.
