Description

Technical Field

[0001] This utility model relates to a low-damage threshing drum device for a seed harvester, belonging to the technical field of threshing drums for seed harvesters. Background Technology

[0002] A seed harvester is a mechanical device specifically designed for collecting crop seeds. It collects seeds mechanically when the crop is mature, typically involving processes such as cutting, picking, and threshing. The design and use of seed harvesters aim to improve the efficiency and accuracy of seed collection while reducing damage to crops. A threshing drum mechanism is required in a seed harvester.

[0003] According to CN221598706U, a double threshing drum device for a harvester is disclosed, including a threshing drum body. Six mounting seats are equidistantly fixed to the surface of the threshing drum body, and each mounting seat has an insertion groove on its side away from the threshing drum body. This invention utilizes the interaction of the threshing drum body, mounting seats, insertion grooves, insertion blocks, toothed spikes, a first slot, a first block, a mounting mechanism, a second slot, a second block, a movable block, a movable groove, a pull plate, a movable rod, a spring, a positioning rod, a fixing block, and positioning holes to facilitate the disassembly of the toothed spikes. When the toothed spikes are damaged, workers can easily remove and replace them, greatly meeting market demand. However, while the device facilitates the disassembly and replacement of the spiked spikes, it cannot adjust the number of working teeth according to the dryness of the crops, which can easily cause grain breakage and affect the threshing effect, thus reducing the device's practicality. Utility Model Content

[0004] The purpose of this invention is to provide a low-breakage threshing drum device for a seed harvester. This invention allows for easy disassembly and replacement of the spikes, and facilitates adjustment of the device according to the crop, reducing grain breakage and improving the threshing effect and practicality of the device, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-damage threshing drum device for a seed harvester includes two fixed discs, with multiple toothed rods arranged in a ring between the fixed discs. Multiple fixed discs are symmetrically fitted on the toothed rods, and multiple spike teeth are arranged in a ring on each of the two fixed discs. Multiple through slots are arranged in a ring on each of the two fixed discs, and cylinders are fixedly installed on the inner walls of each through slot. The output ends of each cylinder are fixedly connected to the adjacent toothed rods.

[0007] Furthermore, a rotating rod is fixedly embedded in one of the two fixed disks, and a wire passage is formed through the rotating rod.

[0008] Furthermore, each of the two fixed disks is provided with a through hole that matches the rotating rod, and each of the inner walls of the through grooves is provided with a wire hole that communicates with the internal space of the adjacent through hole.

[0009] Furthermore, the rotating rod has a symmetrical annular array of holes that match the wire guide holes.

[0010] Furthermore, a plurality of locking screws are inserted through the fixed disk in a circular array, and both ends of the toothed rod are provided with threaded grooves that match the locking screws.

[0011] Furthermore, the toothed bar is provided with a plurality of threaded holes arranged in an array, and each tooth is fixed with a stud that matches the threaded hole.

[0012] Furthermore, the rack and the fixed plate 2, which are located away from the cylinder, are fixedly connected by welding.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a stud, threaded hole, and cylinder. During use, the stud is screwed into the threaded hole, facilitating the disassembly and replacement of the spike teeth. When the crop is dry and easy to thresh, the cylinder moves the corresponding toothed rod inwards, allowing for adjustment of the device. This allows for the combination of three toothed rods for threshing, reducing grain breakage and losses. This invention facilitates the disassembly and replacement of the spike teeth and allows for easy adjustment of the device according to the crop, minimizing grain breakage and improving the threshing effect and practicality of the device.

[0022] 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.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A low-damage threshing drum device for a seed harvester includes two fixed discs 1. A plurality of toothed rods 2 are arranged in a ring between the fixed discs 1. A plurality of fixed discs 2 are symmetrically sleeved on the toothed rods 2. A plurality of nail teeth 4 are arranged in a ring on each of the fixed discs 2. A plurality of through slots 5 are arranged in a ring on each of the fixed discs 2. A cylinder 6 is fixedly installed on the inner wall of each through slot 5. The output end of each cylinder 6 is fixedly connected to the adjacent toothed rod 2.

[0025] Specifically, such as Figures 1-5 As shown, rotating rods 7 are fixedly embedded in both of the two fixed disks 1. A wire passage is opened through the rotating rod 7. A through hole matching the rotating rod 7 is fixedly embedded in each of the two fixed disks 3. A wire hole is opened through the inner wall of each through groove 5, and the wire hole is connected to the internal space of the adjacent through hole. Multiple holes matching the wire holes are symmetrically arranged in a ring on the rotating rod 7. By setting the wire passage, through hole and wire hole, wiring is facilitated. A wire rotating connector is set on one side of the rotating rod 7 to avoid damage to the wire.

[0026] Specifically, such as Figures 1-5As shown, the fixed disk 1 is provided with a ring array of multiple locking screws 8 inserted through it. Both ends of the toothed rod 2 are provided with threaded grooves 9 that match the locking screws 8. The toothed rod 2 is provided with a ring array of multiple threaded holes 10. The nail teeth 4 are provided with studs 11 that match the threaded holes 10. By providing locking screws 8, it is convenient to fix the toothed rod 2 to the fixed disk 1. By providing studs 11 and threaded holes 10, it is convenient to disassemble and replace the nail teeth 4.

[0027] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that the rack 2, which is far from the cylinder 6, and the fixed disk 2 3 are both fixedly connected by welding. By welding the rack 2 to the fixed disk 2 3, the stability of the fixed disk 2 3 can be guaranteed.

[0028] The working principle of this utility model is as follows: When in use, the stud 11 is screwed into the corresponding threaded hole 10, so that the nail tooth 4 can be installed.
