Description

Technical Field

[0001] This utility model relates to the field of agricultural harvester technology, and more specifically to a blade guard device for harvesters. Background Technology

[0002] The working part of a reaper consists of a header with a cutter, a reel, and a conveyor belt. When harvesting vine crops such as peas, existing horizontal reapers usually require the vine crops to be transported laterally and laid out on the side. However, during operation, it is often difficult to lift the soft vines. At the same time, large stones and clods of soil on the ground surface can easily damage the horizontal cutting blades on the header, reducing harvesting efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing a blade protection device for a harvester, which can help lift the vines to avoid clogging during crop harvesting and protect the blades from damage.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: a blade protection device for a slashing machine, comprising a slashing machine cutting platform, wherein a blade protection structure is fixedly installed at the bottom of the slashing machine cutting platform, the blade protection structure comprising a mounting plate, multiple main rods, multiple inclined rods and multiple reinforcing rods, one end of each of the multiple main rods being fixedly connected to one side of the mounting plate, the lower ends of the multiple inclined rods being fixedly connected to the upper sides of the multiple main rods respectively, and reinforcing rods being fixedly connected between the multiple inclined rods and the multiple main rods.

[0005] Preferably, a cross-cutting blade is fixedly installed on one side of the cutting platform of the harvester, and the multiple blades of the cross-cutting blade are arranged interlaced with multiple main rods.

[0006] Preferably, a fixing plate is fixedly connected to the bottom of the cutting platform of the stalking machine, and multiple mounting holes are opened on the outer side of the mounting plate. The multiple mounting holes are connected to the fixing plate by multiple bolts.

[0007] Preferably, the end of the main rod furthest from the mounting plate is provided with a pointed tip.

[0008] Preferably, the angle between the main rod and the diagonal rod is ∠a, and the degree measure of ∠a is 20°~30°.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. Prevent blade damage: By setting up a blade protection structure, the cross-cutting blade is effectively prevented from coming into direct contact with hard objects such as stones and soil during operation, thereby extending the service life of the blade.

[0011] 2. Assisting in lifting crops: The front end of the main stem has a pointed tip that can be inserted into the bottom of the crop to help lift up fallen or tangled vines, thus improving harvesting efficiency.

[0012] 3. Strong structural stability: A reinforcing bar is installed between the main bar and the diagonal bar to form a triangular support structure, which enhances the overall rigidity and impact resistance.

[0013] 4. Easy installation: The blade guard structure is bolted to the bottom fixing plate of the cutter table via the mounting plate, which is convenient for disassembly and maintenance.

[0014] 5. High adaptability: The angle between the main pole and the diagonal pole is designed to be 20°~30°, which takes into account both crop support effect and structural strength, and is suitable for various terrains and crop types. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Please see Figure 1-5The present invention provides the following technical solution: a blade protection device for a slashing machine, comprising a slashing machine cutting platform 1, wherein a blade protection structure 2 is fixedly installed at the bottom of the slashing machine cutting platform 1, the blade protection structure 2 comprising a mounting plate 201, a plurality of main rods 202, a plurality of inclined rods 203 and a plurality of reinforcing rods 204, one end of each of the plurality of main rods 202 being fixedly connected to one side of the mounting plate 201, the lower ends of the plurality of inclined rods 203 being fixedly connected to the upper side of the plurality of main rods 202 respectively, and reinforcing rods 204 being fixedly connected between the plurality of inclined rods 203 and the plurality of main rods 202.

[0024] In this embodiment: the two ends of the reinforcing rod 204 are welded to the main rod 202 and the diagonal rod 203 respectively, forming a closed triangular frame (see attached diagram). Figure 3 After field durability testing, the welds showed no cracks, the overall resonant frequency increased, avoiding the engine's commonly used speed range, significantly reducing resonant fatigue and extending service life.

[0025] As a technical optimization of this utility model, a horizontal cutting blade 101 is fixedly installed on one side of the cutting platform 1 of the reamer, and the multiple blades of the horizontal cutting blade 101 are arranged interlaced with the multiple main rods 202.

[0026] In this embodiment: the blades of the transverse cutting blade 101 alternately intersect the main rod 202 in a transverse direction (see attached diagram). Figure 5 During operation, the blade is always positioned in the "open zone" between the two main poles, ensuring that the vines are completely cut off and that the main poles contact the soil or rocks before the blade, thus achieving "blade protection before cutting" and reducing the chipping rate of the blade by more than 70%.

[0027] As a technical optimization of this utility model, the bottom of the cutting platform 1 of the stalking machine is fixedly connected to a fixing plate 102, and the outer side of the mounting plate 201 is provided with a plurality of mounting holes 2011, and the plurality of mounting holes 2011 are connected to the fixing plate 102 by a plurality of bolts.

[0028] In this embodiment, the fixing plate 102 and the mounting plate 201 are connected by multiple high-strength bolts, forming a "double shear surface" stress structure. Field tests show that under normal operating speed, the bolt preload decreases little, and there is no loosening or displacement after several hours of continuous operation, allowing for quick maintenance through short disassembly and assembly times.

[0029] As a technical optimization of this utility model, the end of the main rod 202 away from the mounting plate 201 is provided with a pointed end 2021, and the included angle between the main rod 202 and the inclined rod 203 is ∠a, the degree of ∠a is 20°~30°.

[0030] In this embodiment: the front end of the main rod 202 is a 20° pointed tip 2021 (see attached diagram). Figure 3This device can easily lift up fallen pea vines, resulting in a high success rate. At the same time, the pointed section has a small moment of inertia, which automatically deflects when encountering stones, reducing impact load.

[0031] The working principle and usage process of this utility model are as follows: During use, the blade guard structure is fixed to the bottom of the harvester's cutting platform via a mounting plate. The pointed end of the main rod first contacts the crop, lifting any fallen or tangled vines and guiding them into the cutting platform area. The cross-cutting blades are staggered with the main rod to ensure the crop is not blocked during cutting. Simultaneously, the blade guard structure formed by the main rod and the diagonal rod effectively blocks hard objects such as stones and clods of soil from impacting the cross-cutting blades, providing protection. The reinforcing rod enhances the overall structural stability, ensuring no deformation or damage under high-intensity operation.

[0032] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
