Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry and agricultural harvesting machinery, in particular to a round grass bale picking and conveying machine. Background Art

[0002] Generally speaking, whether it is the cutting and baling of grass for pastoral storage, or the cutting, crushing, and baling of crops such as corn stalks and wheat stalks, all steps have been mechanized, which greatly saves time and manpower. However, after the bales are compacted and baled, they are discharged on the ground from the discharge port of the picking and baling device. Generally, the bales are loaded manually, that is, the bales are lifted to the carriage of the transport vehicle by manpower using a grass fork, which has high labor intensity and low work efficiency. Traditional forage harvesting also uses a baler to bale the forage first. After the bales are tied, they are manually loaded and unloaded for loading and transportation. Picking up bales wastes manpower, has high labor intensity, and is inefficient, which brings inconvenience to farmers and herdsmen, and also causes unnecessary economic waste, increasing the cost of forage harvesting.

[0003] After searching, the published announcement number CN104186120A is found, which relates to a bale picking device, which includes a picking structure for picking up the bale from the ground, a conveying structure at one end of the picking structure for conveying the bale to a specified position, and a chassis for providing power. The picking structure at least includes a groove-shaped picking frame fixedly connected to the chassis, a picking shaft located at the bottom of the picking frame, and a picking chain located on both sides of the picking frame. The picking shaft rotates and the picking chain rotates, which work together to push the bale obliquely upward.

Anti-slip edges are provided on the outer surfaces of the steering wheels 52. Through the connector 5 and the steering wheels 52 provided on the base frame 1, the staff can connect the device with the power device through the connector 5 when using the device, so as to drive the overall operation of the device, and then through the steering wheels 52 provided on the base frame 1, the function of facilitating the transportation of the device is realized, making the mobile device simpler and more convenient.

[0035] Reference Figure 4-Figure 6 The feed port of the guide rod 4 is in the shape of a funnel with a larger outer end and a smaller inner end. The material receiving frame 33 is in an arc shape as a whole. A positioning rod 331 is fixedly connected between the material receiving frames 33, and a reinforcer 332 is fixedly arranged between the positioning rod 331 and the material receiving frame 33. By setting the feed port of the guide rod 4 in the shape of a funnel with a larger outer end and a smaller inner end, it is achieved that when the device is operating to collect materials, the funnel-shaped guide rod 4 can increase the contact area between the device and the bale, which is convenient for the device to collect and pack materials and improve the operating efficiency of the device.

[0036] Reference Figure 1-Figure 3 The reinforcer 332 includes a flange 6 fixedly set on the material receiving frame 33, and the flange 6 and the material receiving frame 33 are fixedly connected by bolts. A plurality of reinforcing plates 61 are fixedly set between the flange 6 and the positioning rod 331, and the reinforcing plates 61 are set in a right-angled triangle.

When the device is operating to collect materials, the funnel-shaped guide rod 4 can increase the contact surface between the device and the hay bale, which is convenient The device collects and packs materials to improve the operating efficiency of the device. The stability between each material receiving frame 33 is improved by setting a positioning rod 331 between the material receiving frames 33. The stability between the material receiving frames 33 and the positioning rod 331 is further increased by setting a reinforcing plate 61 between the flange 6 and the positioning rod 331, thereby avoiding the misalignment of the material receiving frames 33 during operation of the device. The guide groove 83 set on the guide plate 82 and the limit rod 84 slidably set on the guide groove 83 realize that when the material receiving frame 33 completes feeding, the hydraulic cylinder 31 contracts and retracts the device, and during the retraction process, the limit rod 84 moves along the arc groove 85 in the guide plate 82, thereby controlling the clamping plate 71 to move and clamp the fixed material.
