Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a forage collector. Background Technology

[0002] Hay pickers are used to collect and feed hay and other materials into balers, preparing them for bale formation. Currently, most hay pickers on the market use either an integral or segmented spring-tooth beam structure, with spherical bearing stamped seats at both ends for mounting. Both integral and segmented spring-tooth beams are prone to deformation and damage when the span is large or the feeding volume is high. Furthermore, the dusty operating environment of hay pickers shortens the lifespan of spherical bearings, and the stamped seats are susceptible to deformation and damage under excessive stress, resulting in a high failure rate. In addition, the mounting track and fixed frame of the hay picker are not adjustable, limiting the gap between the picker's spring teeth and the feeding auger, making it unsuitable for feeding both long and short hay.

[0003] Patent CN 210671358 U discloses a wide-range segmented control segmented articulated pickup, including a pickup main shaft, a left spring-tooth beam, a right spring-tooth beam, and spring teeth mounted on the left and right spring-tooth beams. A left spring-tooth beam fixing plate, a middle fixing plate, and a right spring-tooth beam fixing plate are welded to the pickup main shaft. Self-aligning bearings are installed at the right ends of the left and right spring-tooth beams. The left end of the left spring-tooth beam is welded to a left short shaft via the self-aligning bearing, and the right end of the right spring-tooth beam is welded to a right short shaft via the same bearing. The self-aligning bearings at both ends of the left and right spring-tooth beams can adjust their coaxiality, reducing the deformation of the left and right spring-tooth beams. However, the structural strength of the pickup is still relatively low, and severe wear affects structural stability. Furthermore, it is only suitable for picking up forage of a specific length. Therefore, there is a need to develop a forage pickup with high structural strength, resistance to deformation, and applicability to picking up forage and straw of different lengths.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figure 1-5A forage collector includes a spring-loaded beam frame 1, a right spring-loaded beam 2, a left spring-loaded beam 3, and a bearing seat 4. The right spring-loaded beam 2 and the left spring-loaded beam 3 are mounted on the spring-loaded beam frame 1 via the bearing seat 4. The spring-loaded beam frame 1 includes a bearing seat mounting plate 5, a limiting plate 6, and an intermediate shaft tube 7. The bearing seat mounting plate 5 and the limiting plate 6 are mounted on the intermediate shaft tube 7. The bearing seat 4 is fixed on the bearing seat mounting plate 5, and the limiting plate 6 is fixed on the intermediate shaft tube 7. Adjacent limiting plates... 6 forms a limiting groove 8 with the intermediate shaft tube 7. Support blocks 9 and wear-resistant buffer blocks 10 are provided on the right spring tooth beam 2 and the left spring tooth beam 3. A gap is provided between the support block 9 and the intermediate shaft tube 7. The wear-resistant buffer block 10 is in direct contact with the intermediate shaft tube 7 and rotates relative to it. The wear-resistant buffer block 10 is set in the limiting groove 8. The outer ends of the right spring tooth beam 2 and the left spring tooth beam 3 are rotatably mounted on the track plate 11. The track plate 11 is fixed to the side plate 12 of the pickup frame through the mounting holes.

[0027] The right spring tooth beam 2 and the left spring tooth beam 3 are supported on the spring tooth beam frame 1 by the bearing seat 4 and slide and rotate relative to the bearing seat 4; the wear-resistant buffer block 10 is in direct contact with the intermediate shaft tube 7 and rotates relative to it. The wear-resistant buffer block 10 rotates in the limiting groove 8, which supports the left spring tooth beam 3 and the right spring tooth beam 2 without hindering their rotation.

[0028] Furthermore, there are a total of 3 bearing seats 4. The right spring tooth beam 2 is mounted on the spring tooth beam frame 1 through the right bearing seat 4 and the middle bearing seat 4, and the left spring tooth beam 3 is mounted on the spring tooth beam frame 1 through the left bearing seat 4 and the middle bearing seat 4.

[0029] Furthermore, the bearing housing 4 is a wear-resistant plastic bearing housing, and the wear-resistant buffer block 10 is a wear-resistant plastic block.

[0030] The left and right spring tooth beams 3 and 2 operate at low speeds and are equipped with wear-resistant plastic bearing housings to enhance structural reliability and reduce maintenance frequency and costs.

[0031] Furthermore, the gap between the support block 9 and the intermediate shaft tube 7 is 0.5mm to 2mm. When the left spring tooth beam 3 or the right spring tooth beam 2 is slightly deformed, the support block 9 provides auxiliary support.

[0032] Furthermore, the wear-resistant buffer block 10 is disposed in the middle of the right spring tooth beam 2 and the left spring tooth beam 3, and the support block 9 is disposed on both sides of the wear-resistant buffer block 10.

[0033] Further, the right spring-tooth beam 2 includes a right spring-tooth beam body 13, spring teeth 14, a crank arm 15, a bearing I 16, and a sleeve 17. The spring teeth 14 are evenly installed on the right spring-tooth beam body 2. A crank arm 15 is provided at the right end of the right spring-tooth beam body 2, and the bearing I 16 is installed on the crank arm 15. A sleeve 17 is provided at the left end of the right spring-tooth beam body 13. The left spring-tooth beam 3 includes a left spring-tooth beam body 18, spring teeth 14, a crank arm 15, a bearing I 16, and a shaft head 19. The spring teeth 14 are evenly installed on the left spring-tooth beam body 3. A crank arm 15 is provided at the left end of the left spring-tooth beam body 3, and the bearing I 16 is installed on the crank arm 15. A shaft head 19 is provided at the right end of the left spring-tooth beam body 18, and a sleeve 17 is installed on the shaft head 19. A support block 9 and a wear-resistant buffer block 10 are installed on the right spring-tooth beam body 13 and the left spring-tooth beam body 18. 16 rotates along the track of track disk 11, and the outer ends of right spring tooth beam 2 and left spring tooth beam 3 are mounted on track disk 11 via bearing II 22.

[0034] The left and right spring-loaded beams 3 and 2 are mounted together via a shaft head 19 and a sleeve 17, allowing them to rotate relative to each other. This compensates for the inconsistency in rotation between the left and right spring-loaded beams 3 and 2 caused by installation and manufacturing errors in the left and right track disks 11. The left and right spring-loaded beams 3 and 2 are rotatably mounted to the track disk 11 via bearing II 22, and their rotation is limited by bearing I 16 rotating along the track disk 11.

[0035] Furthermore, the bearing I 16 is a double-row angular contact ball bearing.

[0036] The right spring-loaded beam 2 rotates along the right track disk via a double-row angular contact ball bearing on the right side, while the left spring-loaded beam 3 rotates along the left track disk via a double-row angular contact ball bearing on the left side. Double-row angular contact ball bearings have a long service life, high structural strength, can withstand high pressure, and are not easily damaged or deformed.

[0037] Furthermore, the crank arm 15 is fixed to the right spring tooth beam 13 and the left spring tooth beam 18 via a keyway.

[0038] Furthermore, the mounting holes include hole I 20 and hole II 21.

[0039] The mounting holes include multiple holes, enabling an adjustable structure. By selecting different mounting hole positions, the mounting angle of the track disc 11 can be adjusted, thereby adjusting the distance between the pickup teeth and the feeding auger gap, achieving better adaptability of the pickup to feeding long and short hay.

[0040] When the hay picker of this utility model is working, firstly, the position of the mounting holes of the track plate 11 and the side plate 12 of the picker frame is adjusted according to the length of the hay. Then, the power is transmitted to the intermediate shaft tube 7. The rotation of the intermediate shaft tube 7 drives the left spring tooth beam 3 and the right spring tooth beam 2 to rotate through the bearing seat mounting plate 5 and the bearing seat 4. At this time, the wear-resistant buffer block 10 rotates in the limiting groove 8 to support the left spring tooth beam 3 and the right spring tooth beam 2. When the left spring tooth beam 3 and the right spring tooth beam 2 rotate, they drive the bearing 16 to rotate along the track plate 11, and the spring teeth 14 realize the picking of hay, etc.
