Description

Technical Field

[0001] This utility model relates to the field of auger conveying technology, and in particular to a small, independently separated double-helix auger. Background Technology

[0002] The feeding double auger is a key working component in a gourd and melon seed harvester, responsible for conveying the fruit material to subsequent devices. In existing technology, a double-helix conveying auger design with intersecting blades is usually adopted. However, this intersecting auger has problems in practical applications. Its intersecting blade structure is prone to high failure rate, especially when stones are mixed in the material, which can easily cause jamming between the left and right auger blades. This frequent jamming impact will directly affect the transmission system of the gearbox at the upper end of the double auger shaft, leading to an increased chain failure rate and even chain breakage. This seriously affects the operating efficiency and reliability of the combine harvester. In addition, the traditional fixed internal structure also limits the adaptability of the equipment to materials of different sizes, and is inconvenient to operate when cleaning residues inside the auger or performing maintenance.

[0003] Therefore, this application provides a separate, independent double-helix miniature auger to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide an independently separate double-helix auger, which aims to solve the problems of high failure rate, easy jamming, and easy breakage of gearbox chain in existing cross-type augers.

[0005] To achieve the above objectives, this application provides the following technical solution: an independently separate double-helix small auger, including an auger body, the auger body also including an installation box, a conveying chamber and a gearbox, the conveying chamber is provided with a partition, and conveying augers are symmetrically arranged on both sides of the partition. The installation box and a connecting gearbox are respectively connected to both sides of the conveying chamber. The two sets of conveying augers are connected through the connecting gearbox. The installation box is connected to a drive motor through the gearbox. The gearbox is used to drive the conveying augers to rotate. A box cover is bolted to the top of the installation box.

[0006] The inner wall of the conveying bin is provided with a discharge port for discharging materials;

[0007] The conveying bin is also equipped with multiple sets of connecting beams for installing and fixing partitions. Through the cooperation between the above components, the high failure rate of traditional cross augers is effectively avoided, and the conveying efficiency is improved.

[0008] Preferably, the conveying auger is installed inside the conveying chamber, with one end of the conveying auger passing through the conveying chamber and connected to the connecting gearbox, and the other end of the conveying auger passing through the conveying chamber and installed in the mounting box, and the gearbox is connected to either of the two sets of conveying augers.

[0009] Preferably, the conveying bin is equipped with a cover, and multiple sets of covers are provided. At both ends of the conveying bin are mounting plates for installing the covers. Both the connecting beam and the mounting plates are provided with threaded holes for fixing the covers, which facilitates the daily maintenance and repair of the equipment.

[0010] Preferably, the bulkhead also includes a partition plate, which is spliced ​​together from multiple partition plates. Both ends of the upper part of the partition plate are provided with connecting noses. The connecting beam and the mounting plate are provided with mounting grooves that are adapted to the width of the partition plate. The hatch cover is provided with grooves that are adapted to the partition plate. The modular structure significantly improves the disassembly, assembly and adaptability of the bulkhead.

[0011] Preferably, multiple sets of threaded holes are provided on the connecting beam and the mounting plate. These multiple sets of threaded holes are evenly spaced on the connecting beam and the mounting plate, ensuring the stability and convenience of the hatch cover and bulkhead installation.

[0012] Preferably, the hatch cover is equipped with an observation window to facilitate real-time monitoring of material conveying.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] This invention employs an independently designed double-helix auger, with a partition separating it into two independent conveying channels. This fundamentally eliminates the high failure rate caused by interfering with each other's blades and effectively prevents jamming caused by stones entering between the auger blades. Furthermore, the gearbox and auger shaft are directly connected, eliminating the need for chain drive. A buffer or overload protection connector is added to its fixed structure, optimizing the force transmission path and effectively solving the problem of frequent chain breakage due to jamming. This significantly improves the overall stability and reliability of the equipment.

[0015] This invention employs a detachable structure composed of multiple sets of partition panels, featuring unique connecting noses, mounting slots, and grooves to facilitate quick assembly and disassembly of the hatch cover. This allows operators to select whether to install partitions to handle regular grains and prevent stones from getting stuck, or to remove partitions to handle larger, easily tangled materials, thereby merging two independent channels into a larger conveying space and greatly enhancing the equipment's material adaptability and versatility. Simultaneously, the detachable partition design makes cleaning residual waste between the conveying auger and the partitions exceptionally convenient, significantly reducing maintenance difficulty and time costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] refer to Figure 1-6 The diagram shows a separate double-helix auger, comprising an integral auger body 1. The auger body 1 is mainly composed of a mounting box 2, a conveying chamber 3, and a gearbox 4. The conveying chamber 3 is located in the middle part of the auger body 1 and is used for material conveying. The mounting box 2 is located at one end of the conveying chamber 3 and is used to house the drive components.

[0026] As one implementation method in this embodiment, two sets of conveying augers 9 are symmetrically arranged inside the conveying chamber 3. In order to enable these two sets of augers to work independently and avoid mutual interference, a partition 13 is also provided in the conveying chamber 3. The partition 13 divides the conveying chamber 3 into two independent conveying channels, and each conveying auger 9 runs in its own channel. This design can effectively reduce the high failure rate caused by the mutual interference of the auger blades and eliminate the jamming phenomenon caused by the stones entering between the left and right auger blades.

[0027] As one implementation method in this embodiment, in order to achieve synchronous rotation of the two sets of conveying augers 9, one end of the conveying chamber 3 is connected to a connecting gearbox 8. One end of the two sets of conveying augers 9 passes through the conveying chamber 3 and is connected to the connecting gearbox 8. Through the meshing of the gears inside the connecting gearbox 8, the synchronous or reverse rotation of the two auger shafts is ensured.

[0028] As one implementation method in this embodiment, the mounting box 2 is located at the other end of the conveying chamber 3, and a drive mechanism is installed inside it. Specifically, the drive motor 10 is connected to the gearbox 4, which is used to drive the conveying auger 9 to rotate. In this embodiment, the gearbox 4 is connected to either of the two sets of conveying auger 9. When the gearbox 4 drives one set of conveying auger 9 to rotate, the power of the conveying auger 9 is transmitted to the other set of conveying auger 9 through the connecting gearbox 8, thereby realizing the synchronous and efficient operation of the two sets of augers.

[0029] As one implementation method in this embodiment, in order to improve the reliability of the equipment, especially addressing the problem of "high failure rate of gearbox due to jamming and easy chain breakage" in the old design, the gearbox 4 has an improved installation method. It is directly connected to the shaft of the conveying auger 9 in the mounting box 2, eliminating the use of chain drive. This effectively avoids the problem of frequent chain breakage when serious jamming such as blade jamming occurs. At the same time, the fixing structure between the gearbox 4 and the mounting box 2 adopts a connector with buffer or overload protection function, and its installation method optimizes the force transmission path.

[0030] As one embodiment of this example, the top of the mounting box 2 is bolted with a box cover 5, which facilitates the maintenance and repair of the internal drive components. The inner wall of the conveying chamber 3 is provided with a discharge hole 12 for outputting materials, ensuring that the materials can be discharged smoothly.

[0031] As one implementation method in this embodiment, to improve the adaptability and maintainability of the equipment, the partition 13 is designed as a structure that can be easily disassembled. Specifically, the partition 13 is spliced ​​together from multiple sets of partition plates 131, which allows the partition 13 to be installed or disassembled in sections according to the length of the conveying chamber 3. Each set of partition plates 131 has connecting noses 132 at both ends of its upper part. Inside the conveying chamber 3, multiple sets of connecting beams 7 for installing and fixing the partition 13 are provided along its length. At both ends of the conveying chamber 3, there are compartment covers for installation. The mounting plate 11 of the 6, the connecting beam 7, and the mounting plate 11 are all provided with mounting grooves 71 that are adapted to the width of the partition plate 131. When the partition plate 131 is installed, its lower end can slide into these mounting grooves 71 for positioning and support. At the same time, the conveying chamber 3 is also provided with multiple sets of hatch covers 6 to cover the opening above the conveying chamber 3. The connecting beam 7 and the mounting plate 11 are all provided with multiple sets of threaded holes for fixing the hatch covers 6, and these threaded holes are evenly spaced on the connecting beam 7 and the mounting plate 11 to ensure the stable installation of the hatch covers 6.

[0032] As one implementation method in this embodiment, in order to achieve quick installation and disassembly of the partition plate 131, the hatch cover 6 is provided with a groove that matches the partition plate 131. When the lower end of the partition plate 131 is inserted into the mounting groove 71, the connecting nose 132 at the upper part can be inserted into or positioned in the groove on the hatch cover 6. After the hatch cover 6 is fixed to the connecting beam 7 and the threaded holes on the mounting plate 11 by bolts, the partition plate 131 can be firmly pressed and positioned. When it is necessary to disassemble the partition plate 131, simply remove the corresponding hatch cover 6 to easily remove the partition plate 131, achieving quick disassembly and assembly. In order to facilitate observation of the material conveying situation inside the conveying chamber 3, an observation window can also be provided on the hatch cover 6.

[0033] The working principle of this utility model is as follows: When the equipment is started, the drive motor 10 provides power, which is transmitted through the gearbox 4. The gearbox 4 is connected to one of the two sets of conveying augers 9. When the gearbox 4 drives the shaft of this auger to rotate, its power will be transmitted through the connecting gearbox 8 located at the other end of the conveying chamber 3 and synchronously drive the other conveying auger 9 to rotate. In this way, the two sets of conveying augers 9 can start rotating at the same time to carry out the material conveying work.

[0034] When it is necessary to process regular grains, or foreign objects such as stones, or when precise diversion of materials is required: the operator installs the partition 13, which is spliced ​​from the partition plate 131, on the connecting beam 7 and the mounting plate 11 inside the conveying chamber 3, and fixes it by using the groove on the cover 6 to cooperate with the connecting nose 132, and then tightens the bolts on the cover 6. At this time, the conveying chamber 3 is divided into two independent conveying channels by the partition 13.

[0035] When dealing with larger, easily tangled, or materials with high throughput requirements and less stringent jam control requirements, operators can open the corresponding hatch 6 and remove the partition plate 131 from the mounting slot 71, thereby merging the two independent channels into a larger conveying space. This detachable design allows the equipment to flexibly adapt to different material characteristics and facilitates disassembly and maintenance of the conveying auger 9 and the partition plate 13 for residual waste.

[0036] Once ready, the operator will usually remove the cover 6 on the side near the installation box 2 and use the opening as the feed inlet. After the material is put into the feed inlet, it will be pushed forward along the inside of the conveying chamber 3 under the action of two sets of synchronously rotating conveying augers 9. The material will be continuously conveyed under the spiral action of the conveying augers 9 until it reaches the discharge hole 12 opened on the inner wall of the conveying chamber 3 and is discharged from the hole to the next working stage.

[0037] Components not described in detail in this article are existing technologies.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
