Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a feeding device and agricultural machinery. Background Technology
[0002] When a harvester is operating in the field, the header feeds the cut crop into the bridge, which then transports the crop to the drum feeder, where it enters the drum for threshing. During this process, metal objects may enter the drum due to ground conditions or improper operator handling, or the internal toothed rods may break, damaging the drum feeder and causing the harvester to stop and malfunction. Current technology typically welds the drum feeder to the drum wall. If the drum feeder is damaged, it cannot be easily repaired; the entire drum wall must be replaced, presenting a problem of inconvenient disassembly and maintenance. Utility Model Content
[0003] The purpose of this invention is to provide a feeding device and agricultural machinery that solves the problem of inconvenient disassembly and maintenance of feeding devices in the prior art.
[0004] To achieve the above objectives, this utility model provides a feeding device, which includes:
[0005] Locking fasteners;
[0006] The drum has a processing chamber inside for processing materials, and one end of the processing chamber is open.
[0007] The feeding assembly extends into the processing chamber from one side through an opening, and has a mounting strip on the other side that is detachably connected to the end of the roller. The feeding assembly includes multiple feeding parts, and any two adjacent feeding parts are detachably connected by a locking fastener. The multiple feeding parts enclose a feeding inlet for feeding materials, and the feeding inlet communicates with the processing chamber.
[0008] In the embodiments of this utility model, a protrusion is formed on the side of any two adjacent feeding parts that are close to each other. Each protrusion has multiple corresponding connecting holes, and the number of locking fasteners is multiple and they correspond one-to-one through the connecting holes.
[0009] In an embodiment of this utility model, the end of the feeding inlet facing the processing cavity has an arc-shaped structure.
[0010] In an embodiment of this utility model, among a plurality of sequentially connected feeding parts, the two feeding parts at the beginning and end have inclined guide surfaces, and the plurality of feeding parts in the middle each have concave guide surfaces. The two inclined guide surfaces and the plurality of concave guide surfaces enclose and form the side wall of the feeding inlet.
[0011] In an embodiment of this utility model, an installation strip is installed on the side of the inclined guide surface away from the machining cavity, and an installation strip is installed on the side of the concave guide surface away from the machining cavity.

[0024] Detailed Implementation
[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0026] The feeding device and agricultural machinery according to the present invention are described below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a feeding device is proposed, which includes a locking fastener 1, a roller, and a feeding assembly. The roller has a processing chamber for processing materials, and one end of the processing chamber is open for the feeding assembly to be inserted. One side of the feeding assembly extends into the processing chamber from the open end, and the other side has a mounting strip 21 that is detachably connected to the end of the roller. The feeding assembly includes multiple feeding parts 22, and any two adjacent feeding parts 22 are detachably connected by the locking fastener 1. The multiple feeding parts 22 surround to form a feeding inlet 23 for feeding materials, and the feeding inlet 23 communicates with the processing chamber.
[0028] This embodiment provides a feeding device. One side of the feeding component has a mounting strip 21 that is detachably connected to the end of the roller. If the feeding component is damaged, the damaged feeding component can be easily removed from the roller and replaced with a new feeding component, thereby achieving rapid maintenance and replacement of the feeding component. Furthermore, any two adjacent feeding parts 22 in the feeding component are detachably connected by a locking fastener 1. If any feeding part 22 in the feeding component is damaged, only the damaged feeding part 22 can be replaced, thereby reducing the overall maintenance cost of the feeding component.
[0029] like Figure 1As shown, in this embodiment, a protrusion 221 is formed on the side of any two adjacent feeding parts 22 that are close to each other. Each protrusion 221 has multiple corresponding connecting holes, and there are multiple locking fasteners 1 that correspond to the connecting holes one by one. The locking fasteners 1 can be screws in the prior art. The feeding device is also provided with nuts that are threadedly engaged with the screws to achieve locking between adjacent feeding parts 22.
[0030] Specifically, in this embodiment, there are four feeding parts 22. Four connecting holes are provided on the protrusions 221 of the two feeding parts 22 located in the middle, close to each other. These four connecting holes are spaced apart along the length of the protrusions 221. The number of locking fasteners 1 is correspondingly set to four. In this embodiment, the locking fasteners 1 pass through the connecting holes, thereby ensuring a stable connection between the two feeding parts 22 located in the middle. Five connecting holes are provided on the protrusions 221 of the feeding parts 22 located at the beginning or end, close to each other. These five connecting holes are spaced apart along the length of the protrusions 221. The number of locking fasteners 1 is correspondingly set to five. Similarly, the locking fasteners 1 pass through the connecting holes, thereby ensuring a stable connection between the feeding parts 22 located at the beginning or end and the adjacent feeding parts 22, ensuring the assembly strength of the feeding assembly. The number of connecting holes on the protrusions 221 can be adjusted according to actual needs.
[0031] like Figure 1 As shown, in this embodiment, the end of the feeding inlet 23 facing the processing cavity has an arc-shaped structure, which facilitates the material to smoothly enter the processing cavity from the feeding inlet 23 for processing under the guidance of the feeding component, ensuring that the feeding component can continuously provide sufficient material to the processing cavity.
[0032] like Figure 1 As shown, in this embodiment, among the multiple sequentially connected feeding sections 22, the first and last feeding sections 22 have inclined guide surfaces 222, resulting in higher structural strength and better stability. The middle feeding sections 22 each have concave guide surfaces 223, and the two inclined guide surfaces 222 and the multiple concave guide surfaces 223 together form the sidewall of the feeding inlet 23. In this embodiment, the two middle feeding sections 22 each have concave guide surfaces 223, which guide the material, facilitating its smooth entry into the processing chamber of the roller for processing.
[0033] In this embodiment, mounting strips 21 are installed on the side of the inclined guide surface 222 facing away from the processing cavity, and mounting strips 21 are also installed on the side of the concave guide surface 223 facing away from the processing cavity. The mounting strips 21 on the middle feeding section 22 extend in the left-right direction, while the two mounting strips 21 at the beginning and end extend in the height direction. All mounting strips 21 are located in the same horizontal plane, ensuring that the feeding assembly can be stably mounted on the roller. The height direction is... Figure 1 The up and down directions in the middle.
[0034] In this embodiment, the tilt angle of the inclined guide surface 222 is in the range of 45°-60°. Preferably, in this embodiment, the tilt angle of the inclined guide surface 222 is set to 60°. At this angle, the feeding parts 22 at the beginning and end have good structural stability and can be stably connected with the feeding part 22 in the middle.
[0035] like Figure 1 As shown, in this embodiment, the number of feeding parts 22 is an even number, and the multiple feeding parts 22 located in the middle are symmetrically arranged. Preferably, the number of feeding parts 22 can be set to four or six. In this embodiment, four feeding parts 22 are used as an example. If the number of feeding parts 22 is too large, it will lead to poor overall structural stability of the feeding component, and too many installation steps between multiple feeding parts 22, making the installation process complicated and not conducive to quick disassembly.
[0036] like Figure 1 As shown, in this embodiment, the mounting strip 21 of the feed section 22 at the beginning and end is provided with a plurality of clearance notches 224, which serve to avoid other components on the feed device and prevent interference to other components when the mounting strip 21 is detachably connected to the end face of the roller.
[0037] In this embodiment, the feeding device also includes locking components. Each mounting strip 21 has multiple mounting holes 225, and the locking components are multiple and correspond one-to-one with the mounting holes 225. The mounting strips 21 of the feed sections 22 at both ends are each provided with 5 mounting holes 225, and the multiple mounting holes 225 are arranged at intervals along the vertical direction. The number of mounting holes 225 can be adjusted according to actual needs. Preferably, the multiple feed sections 22 in this embodiment can all be made of national standard Q355B alloy steel, which has high structural strength, is not easily damaged, and has a long service life. The locking components can be screws as used in the prior art; the screws, in conjunction with nuts, achieve locking between the roller and the feeding assembly.
[0038] In this embodiment, an agricultural machine is also proposed, including the feeding device described above. Since the agricultural machine employs all embodiments of the feeding device described in this application, it also possesses all the beneficial effects of the feeding device, which will not be elaborated upon here. Specifically, the agricultural machine includes machinery such as harvesters.
