Description

Technical Field

[0001] This utility model relates to the field of crop dividers, specifically to a crop divider for agricultural and forestry harvesters. Background Technology

[0002] A combine harvester is an agricultural machine primarily used for harvesting crops such as wheat, rice, and corn. Its basic working principle involves blades or cutting devices cutting the crops, which are then collected by a conveyor belt or other means. The divider is the core component at the front of the harvester's header, directly affecting harvesting quality and efficiency. Its primary function is to separate the crops, straighten lodged plants, and create an orderly environment for subsequent cutting and transport.

[0003] In current harvesting operations, due to the variety of major agricultural and forestry crops and varying terrain, different types of harvester dividers are needed to meet the harvesting and usage habits of different regions. Currently, most dividers consist of a shell and a head. Some manufacturers, to ensure the divider's wear resistance, make both the shell and head metal and weld them together. While this design enhances the divider's wear resistance, the head, located at the front of the harvester, experiences the most wear. If damaged, the entire divider must be replaced, making disassembly and assembly difficult and costly.

[0004] Some manufacturers use engineering plastics for both the shell and the head, which reduces replacement costs. However, because the head is subjected to impact for extended periods, it has poor wear resistance and is prone to wear and deformation. This leads to more frequent replacements of the divider, which is not conducive to long-term harvesting operations.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] This utility model provides a divider for agricultural and forestry harvesters, aiming to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a divider for an agricultural and forestry harvester, comprising a plastic shell and a metal tip; the two ends of the plastic shell are an open covering end and a closed connecting end, respectively; along the length of the plastic shell, any cross-section of the plastic shell is C-shaped, and the width of the plastic shell decreases linearly from the covering end to the connecting end; the plastic shell is positioned and connected to the harvester through the covering end, and the plastic shell is positioned and connected to the metal tip through the connecting end; a sealing plate is provided at the C-shaped opening of the plastic shell to form an installation chamber inside the plastic shell; the metal tip includes a metal base plate, and the metal base plate is disposed on the sealing plate. On the side of the metal base plate away from the plastic shell, a metal head is positioned and connected to the side of the metal base plate facing the plastic shell. The metal head is located at the end of the metal base plate. When the metal base plate is positioned on the sealing plate, the metal head is directly opposite and close to the connecting end. The width of the metal head decreases from the end closer to the connecting end to the end farther away from the connecting end, and the maximum width of the metal head is equal to or less than the width of the connecting end. It also includes at least two connectors. Multiple positioning parts are provided at the same positions on the metal base plate and the sealing plate. Each connector corresponds to and cooperates with each positioning part, so that the metal tip and the plastic shell form a detachable connection structure.

[0008] The relevant content in the above plan is explained as follows:

[0009] In the above scheme, any cross-section of the metal head is also C-shaped. Compared with the solid structure, this C-shaped structure is lighter and less expensive.

[0010] In the above scheme, the width of the metal head decreases from the end closer to the connection end to the end farther away from the connection end. The maximum width of the metal head is equal to or less than the width of the connection end. This design is to ensure that debris passes through the metal head more smoothly, thereby reducing the resistance to the passage of debris, and at the same time, it is easier to guide debris to pass through from both sides of the metal head.

[0011] In the above solution, the connector mainly serves to fix the metal base plate and the enclosed plate, and can be selected from screws, pins, etc.

[0012] In the above solution, the metal base plate and the sealing plate can be quickly disassembled and assembled using the connector and the positioning part. Specifically, the metal base plate is directly attached to the sealing plate, and the metal tip is guided to face and fit tightly against the connecting end. Then, through the cooperation of the connector and the positioning part, the metal tip and the plastic shell can be fixed together to form a detachable connection structure.

[0013] In the above solution, the plastic shell and the metal tip form a detachable connection structure. If one of them is damaged, it can be quickly removed and replaced. Compared with the integrated design of the plastic shell and the metal tip, the disassembly and assembly are easier and the replacement cost is lower.

[0014] At the same time, unlike the shell and head made of engineering plastics, the metal tip in this application has high strength and will not easily wear out.

[0015] In a further technical solution, the metal base plate includes a first plate that is positioned and connected to the metal head and a second plate disposed at the end of the first plate; the second plate is deflected at a set angle toward the metal head with the connection point with the first plate as the center line and having the end with the maximum width.

[0016] With the above design, the largest end of the metal head can be tightly attached to the connecting end. When debris comes into contact with the metal head, the tapered slope will decompose the axial propulsion force into lateral components on both sides, pushing the debris to slide to both sides along the head contour, avoiding forward blockage. At the same time, the largest end of the metal head being tightly attached to the connecting end can prevent debris from blocking the connection between the two.

[0017] In a further technical solution, the connecting component is a screw; the positioning part is a screw hole located at the same position on the metal base plate and the sealing plate.

[0018] The above design allows for the assembly and disassembly of the metal base plate and the enclosure plate.

[0019] That is, the screw and the screw hole cooperate to form a detachable connection between the metal tip and the plastic shell. The above is the first embodiment of the connection between the connector and the positioning part.

[0020] A second implementation method can also be provided for the cooperation between the connector and the positioning part, as follows:

[0021] In a further technical solution, the metal base plate also includes a reinforcing plate integrally connected to the surface of the second plate away from the closing plate. The reinforcing plate is arranged along the length direction of the second plate and located in the middle region of the second plate. The width of the reinforcing plate is smaller than the width of the second plate, and limiting grooves are formed on both sides of the width direction of the second plate.

[0022] The above design increases the thickness of the metal base plate, providing strength support for subsequent fixing operations.

[0023] A further technical solution is provided with a pair of limiting blocks on the side surface of the sealing plate away from the plastic shell. The pair of limiting blocks are symmetrically arranged with reference to the center line connecting the two sides of the sealing plate in the two width directions. The opposite side surface of the pair of limiting blocks is provided with a locking part, which is matched with the limiting groove. When the metal base plate is positioned on the sealing plate, the locking part and the limiting groove cooperate to make the metal base plate and the sealing plate form a sliding insertion structure.

[0024] The above design allows the locking part to cooperate with the limiting groove to limit the movement of the metal base plate.

[0025] Specifically, the limiting groove is directly guided to align with the locking part, while the closing plate is driven to be parallel to the second plate. Then, the second plate is guided to slide on the closing plate so that the limiting groove fully accommodates the locking part. That is, through the cooperation between the locking part and the limiting groove, the metal base plate and the closing plate form a sliding insertion structure.

[0026] In this way, the second plate will not easily detach; it needs to be guided in the opposite direction to slide on the closed plate before the metal base plate can be removed.

[0027] In a further technical solution, the positioning part is a locking hole formed by the indentation of the surface of the reinforcing plate and the passage through the second plate.

[0028] The positioning hole is located in the center area of ​​the reinforcing plate surface and occupies at least half of the width of the reinforcing plate. This ensures that the positioning hole and the connector have sufficient contact and the connection strength is adequate.

[0029] The engagement between the locking hole and the connector can be either a pin engagement or a screw engagement.

[0030] A further technical solution includes an elastic element disposed within the mounting cavity, with a locking block extending out of the mounting cavity mounted at the end of the elastic element. The locking block is the connecting element. A limiting cylinder is provided on the outer side of the elastic element to limit the locking block so that the locking block can only move up and down. When the metal base plate is positioned on the closed plate, the locking block is configured to be embedded in the locking hole. The elastic element acts on the locking block so that the locking block always tends to extend into the locking hole.

[0031] The limiting sleeve is used to prevent the elastic element, i.e., the spring, from bending around its periphery.

[0032] With the help of the above design, unlike the fit between screws and screw holes, the locking block and locking hole can be disassembled and assembled more quickly.

[0033] Specifically, during the process of the second plate sliding on the closed plate to allow the limiting groove to fully accommodate the locking part, the second plate will first contact the protruding end of the locking block and press the protruding end of the locking block. Then the locking block will be pressed into the installation chamber, and at the same time the locking block will compress the elastic element.

[0034] As the second plate continues to slide on the closed plate, the locking hole on the second plate will align with the protruding end of the locking block. At this time, the locking block is no longer under pressure, and the protruding end will be locked into the locking hole under the action of the reset elastic element, so that the position of the second plate is restricted by the locking block.

[0035] At this time, the locking part and the limiting groove will limit the second plate once, and the locking block and the locking hole will limit the second plate a second time. Under the action of the two limits, the second plate will not move easily. Only by pressing the two locking blocks at the same time, so that both of them are disengaged from the locking hole, can the unlocking operation be achieved.

[0036] It should be noted that the protruding end of the locking block is flush with the surface of the limiting block. When the protruding end of the locking block is inserted into the locking hole, the protruding end of the locking block, the surface of the reinforcing plate, and the surface of the limiting block are flush.

[0037] A further technical solution is provided with a guide slope on the upper surface edge of the locking block. When the metal base plate is slidably inserted into the closing plate, the guide slope is configured to face the sliding direction of the metal base plate to guide the locking part to slide unidirectionally into the limiting groove until the metal base plate is positioned on the closing plate; the side surface of the upper end of the locking block opposite to the guide slope serves as a limiting part to prevent the metal base plate from sliding away from the closing plate.

[0038] With the above design, the second plate can slide on the closed plate so that the limiting groove can fully accommodate the locking part. During this process, the second plate can easily press the protruding end of the locking block without the need for external force.

[0039] Specifically, when the second plate slides on the closed plate and contacts the locking block, it will first contact the guide ramp. Since the guide ramp is configured to slide in the direction of the metal base plate, the second plate will press the locking block into the locking hole along the guide ramp.

[0040] Once the end of the locking block is inserted into the locking hole under the action of the resetting elastic element, the upper end of the locking block and the side surface opposite to the guide slope will restrict the metal base plate from sliding away from the closing plate.

[0041] In a further technical solution, the end of the reinforcing plate is provided with an arc surface.

[0042] The above design ensures that debris will not be blocked when it comes into contact with the end of the reinforcing plate.

[0048] The working principle and advantages of this utility model are as follows:

[0049] In this application, the metal base plate and the sealing plate can be quickly disassembled and assembled using the connector and the positioning part. Specifically, the metal base plate is directly attached to the sealing plate, and the metal tip is guided to face and fit tightly against the connecting end. Then, through the cooperation of the connector and the positioning part, the metal tip and the plastic shell can be fixed together to form a detachable connection structure.

[0050] In this application, the plastic shell and the metal tip form a detachable connection structure. When one of them is damaged, it can be quickly removed and replaced. Compared with the integrated design of the plastic shell and the metal tip, the disassembly and assembly are easier and the replacement cost is lower.

[0051] Meanwhile, unlike the shell and head made of engineering plastics, the metal tip in this application has high strength and will not easily wear out, which is beneficial to improving the overall structural strength and service life of the divider and is conducive to the long-term continuous operation of the harvester.

[0064] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0065] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0066] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0067] See appendix Figures 1-11 As shown, a divider for an agricultural and forestry harvester includes a plastic shell 1 and a metal tip 2. The plastic shell 1 has an open covering end 3 and a closed connecting end 4 at its two ends. Along the length of the plastic shell 1, any cross-section of the plastic shell 1 is C-shaped, and the width of the plastic shell 1 decreases linearly from the covering end 3 to the connecting end 4. The plastic shell 1 is positioned and connected to the harvester via the covering end 3, and is positioned and connected to the metal tip 2 via the connecting end 4. A sealing plate 5 is provided at the C-shaped opening of the plastic shell 1 to form an installation chamber inside the plastic shell 1. The metal tip 2 includes a metal base plate 6, which is located on the side of the sealing plate 5 away from the plastic shell 1. On the surface of the metal base plate 6, a metal head 7 is positioned and connected to the side of the plastic shell 1. The metal head 7 is located at the end of the metal base plate 6. When the metal base plate 6 is positioned on the sealing plate 5, the metal head 7 is directly opposite and close to the connecting end 4. The width of the metal head 7 decreases from the end closer to the connecting end 4 to the end farther away from the connecting end 4. The maximum width of the metal head 7 is equal to or less than the width of the connecting end 4. It also includes at least two connectors 8. Multiple positioning parts 9 are provided at the same positions on the metal base plate 6 and the sealing plate 5. Each connector 8 is respectively matched with each positioning part 9 to make the metal tip 2 and the plastic shell 1 form a detachable connection structure.

[0068] In this application, any cross-section of the metal head 7 is also C-shaped. Compared to a solid structure, this C-shaped structure is lighter and less expensive. Generally, the C-shaped opening of the plastic shell 1 is a smooth straight line, as shown in the example below. Figure 2 .

[0069] In this application, the width of the metal head 7 decreases from the end closer to the connecting end 4 to the end farther away from the connecting end 4. The maximum width of the metal head 7 is equal to or less than the width of the connecting end 4. This design is to ensure that debris passes through the metal head 7 more smoothly, thereby reducing the resistance to the passage of debris, and at the same time, it is easier to guide debris to pass through from both sides of the metal head 7.

[0070] In this application, the connector 8 mainly serves to fix the metal base plate 6 and the closed plate 5, and can be selected from screws, pins, etc.

[0071] In this application, the metal base plate 6 and the sealing plate 5 can be quickly disassembled and assembled using the connector 8 and the positioning part 9. Specifically, the metal base plate 6 is directly attached to the sealing plate 5, and the metal head 7 is guided to face and be close to the connecting end 4. Then, through the cooperation of the connector 8 and the positioning part 9, the metal tip 2 and the plastic shell 1 can be fixed together to form a detachable connection structure.

[0072] In this application, the plastic shell 1 and the metal tip 2 form a detachable connection structure. When one of them is damaged, it can be quickly removed and replaced. Compared with the integrated design of the plastic shell 1 and the metal tip 2, the disassembly and assembly are easier and the replacement cost is lower.

[0073] Meanwhile, unlike the shell and head made of engineering plastic, the metal tip 2 in this application has high strength and will not easily wear out.

[0074] Preferably, the metal base plate 6 includes a first plate 10 positioned and connected to the metal head 7 and a second plate 11 disposed at the end of the first plate 10; the second plate 11 is deflected at a set angle toward the metal head 7 with the connection point with the first plate 10 as the center line and having the end with the maximum width.

[0075] With the above design, the largest end of the metal head 7 can be tightly attached to the connecting end 4. When debris comes into contact with the metal head 7, the tapered slope will decompose the axial propulsion force into lateral components on both sides, pushing the debris to slide to both sides along the head contour, avoiding forward blockage. At the same time, the largest end of the metal head 7 is tightly attached to the connecting end 4, which can prevent debris from blocking the connection between the two.

[0076] The angle setting can be referenced. Figure 3 The bending situation in the middle.

[0077] Preferably, the connector 8 is a screw; the positioning part 9 is a screw hole 13 located at the same position on the metal base plate 6 and the sealing plate 5.

[0078] The above design allows for the assembly and disassembly of the metal base plate 6 and the enclosure plate 5.

[0079] That is, the screw and the screw hole 13 cooperate to form a detachable connection between the metal tip 2 and the plastic shell 1. The above is the first embodiment of the connection between the connector 8 and the positioning part 9.

[0080] A second implementation method can also be provided for the cooperation between the connector 8 and the positioning part 9, as follows:

[0081] Preferably, the metal base plate 6 further includes a reinforcing plate 14 integrally connected to the surface of the second plate 11 away from the closing plate 5. The reinforcing plate 14 is arranged along the length direction of the second plate 11 and located in the middle region of the second plate 11. The width of the reinforcing plate 14 is smaller than the width of the second plate 11, and limiting grooves 15 are formed on both sides of the width direction of the second plate 11.

[0082] The thickness of the metal base plate 6 is increased by using the above design to provide strength support for subsequent fixing operations.

[0083] Preferably, a pair of limiting blocks 16 are provided on the side surface of the sealing plate 5 away from the plastic shell 1. The pair of limiting blocks 16 are symmetrically arranged with reference to the center line connecting the two sides of the sealing plate 5 in the two width directions. The opposite side surface of the pair of limiting blocks 16 is provided with a locking part 17, which is matched with the limiting groove 15. When the metal base plate 6 is positioned on the sealing plate 5, the locking part 17 and the limiting groove 15 cooperate to make the metal base plate 6 and the sealing plate 5 form a sliding insertion structure.

[0084] With the above design, the locking part 17 can cooperate with the limiting groove 15 to limit the metal base plate 6.

[0085] Specifically, the limiting groove 15 is directly guided to align with the locking part 17, while the closing plate 5 is driven to be parallel to the second plate 11. Then, the second plate 11 is guided to slide on the closing plate 5 so that the limiting groove 15 fully accommodates the locking part 17. That is, through the cooperation between the locking part 17 and the limiting groove 15, the metal base plate 6 and the closing plate 5 form a sliding insertion structure.

[0086] In this way, the second plate 11 will not easily detach, and it is necessary to guide the second plate 11 in the opposite direction to slide on the closed plate 5 in order to remove the metal base plate 6.

[0087] Preferably, the positioning part 9 is a locking hole 18 formed by the recess of the surface of the reinforcing plate 14 and passing through the second plate 11.

[0088] The locking hole 18 is located in the center area of ​​the surface of the reinforcing plate 14 and occupies at least half of the width of the reinforcing plate 14. This ensures that the locking hole 18 and the connector 8 have sufficient contact and the connection strength is sufficient.

[0089] The engagement between the locking hole 18 and the connector 8 can be either a pin engagement or a screw engagement.

[0090] Preferably, the connector 8 includes an elastic element 19 disposed in the mounting cavity, and a locking block 20 extending out of the mounting cavity is installed at the end of the elastic element 19. The locking block 20 is the connector 8. A limiting cylinder 21 is provided on the outer side of the elastic element 19 to limit the locking block 20 so that the locking block 20 can only move up and down. When the metal base plate 6 is positioned on the closed plate 5, the locking block 20 is configured to be embedded in the locking hole 18. The elastic element 19 acts on the locking block 20 so that the locking block 20 always tends to extend into the locking hole 18.

[0091] The limiting cylinder 21 is used to prevent the elastic element 19, i.e. the spring, from bending around its periphery.

[0092] With the above design, unlike the screw and screw hole 13, the locking block 20 and locking hole 18 can be disassembled and assembled more quickly.

[0093] Specifically, during the process of the second plate 11 sliding on the closed plate 5 to allow the limiting groove 15 to fully accommodate the locking part 17, the second plate 11 will first contact the protruding end of the locking block 20 and press the protruding end of the locking block 20. Then the locking block 20 will be pressed into the installation chamber, and at the same time the locking block 20 will compress the elastic member 19.

[0094] As the second plate 11 continues to slide on the closed plate 5, the locking hole 18 on the second plate 11 will align with the protruding end of the locking block 20. At this time, the locking block 20 is no longer under pressure, and the protruding end will be locked into the locking hole 18 under the action of the reset elastic member 19, so that the position of the second plate 11 is restricted by the locking block 20.

[0095] At this time, the locking part 17 and the limiting groove 15 cooperate to limit the second plate 11 once, and the locking block 20 and the locking hole 18 cooperate to limit the second plate 11 a second time. Under the action of the two limits, the second plate 11 will not move easily. Only by pressing the two locking blocks 20 at the same time, so that both of them are disengaged from the locking hole 18, can the unlocking operation be achieved.

[0096] It should be noted that the protruding end of the locking block 20 is flush with the surface of the limiting block 16. When the protruding end of the locking block 20 is inserted into the locking hole 18, the protruding end of the locking block 20, the surface of the reinforcing plate 14, and the surface of the limiting block 16 are flush.

[0097] Preferably, the upper surface edge of the locking block 20 is provided with a guide slope 12. When the metal base plate 6 is slidably inserted into the closing plate 5, the guide slope 12 is configured to face the sliding direction of the metal base plate 6 to guide the locking part 17 to slide unidirectionally into the limiting groove 15 until the metal base plate 6 is positioned on the closing plate 5. The side surface of the upper end of the locking block 20 opposite to the guide slope 12 serves as a limiting part to prevent the metal base plate 6 from sliding away from the closing plate 5.

[0098] With the above design, the second plate 11 slides on the closed plate 5 so that the limiting groove 15 can fully accommodate the locking part 17. During this process, the second plate 11 can easily press the protruding end of the locking block 20 without the need for external force.

[0099] Specifically, when the second plate 11 slides on the closed plate 5 and contacts the locking block 20, it will first contact the guide slope 12. Since the guide slope 12 is configured to slide in the direction of the metal base plate 6, the second plate 11 will press the locking block 20 into the locking hole 18 along the guide slope 12.

[0100] Once the protruding end of the locking block 20 is engaged in the locking hole 18 under the action of the reset elastic member 19, the upper end of the locking block 20 and the side surface opposite to the guide slope 12 will restrict the metal base plate 6 from sliding away from the closing plate 5.

[0101] Preferably, the end of the reinforcing plate 14 is provided with an arc surface.

[0102] The above design ensures that debris will not be blocked when it comes into contact with the end of the reinforcing plate 14.

[0103] Working principle (taking the second embodiment as an example): The direct guide limiting groove 15 is aligned with the locking part 17, while driving the closing plate 5 to be parallel with the second plate 11. Then, the guide second plate 11 slides on the closing plate 5 so that the limiting groove 15 fully accommodates the locking part 17. That is, through the cooperation between the locking part 17 and the limiting groove 15, the metal base plate 6 and the closing plate 5 form a sliding insertion structure.

[0104] As the second plate 11 slides on the closed plate 5 to allow the limiting groove 15 to fully accommodate the locking part 17, the second plate 11 will first contact the protruding end of the locking block 20 and press the protruding end of the locking block 20. Then the locking block 20 will be pressed into the installation chamber, and at the same time the locking block 20 will compress the elastic member 19.

[0105] As the second plate 11 continues to slide on the closed plate 5, the locking hole 18 on the second plate 11 will align with the protruding end of the locking block 20. At this time, the locking block 20 is no longer under pressure, and the protruding end will be locked into the locking hole 18 under the action of the reset elastic member 19, so that the position of the second plate 11 is restricted by the locking block 20.

[0106] At this time, the locking part 17 and the limiting groove 15 cooperate to limit the second plate 11 once, and the locking block 20 and the locking hole 18 cooperate to limit the second plate 11 a second time. Under the action of the two limits, the second plate 11 will not move easily. Only by pressing the two locking blocks 20 at the same time, so that both of them are disengaged from the locking hole 18, can the unlocking operation be achieved.
