Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an automatic conveying, breaking and crushing machine for square hay bales. Background Technology

[0002] Straw bales are bundles of hay, straw, or other agricultural crops that have been cut, dried, and tied into bundles of a certain length and weight. Because straw bales are quite sturdy, they are not convenient to use directly and need to be untied and broken up before they can be used.

[0003] Currently, large and medium-sized farms basically handle high-density hay bales by manually breaking them up and then using a hay cutter to shred them to meet feeding standards. This traditional method is inefficient and creates a poor working environment.

[0004] Therefore, those skilled in the art urgently need to develop an automatic conveying, breaking, and crushing machine for straw bales. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic conveying, breaking, and crushing machine for square bales.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic bale conveying and shredding machine for square straw bales, comprising a frame, a flat plate on the frame, a rotatable rotating chamber movably mounted on the flat plate, a feeding plate fixedly connected to the inner wall of the rotating chamber, a feeding port at the bottom of the rotating chamber, a shredding box and a screening box arranged sequentially below the flat plate, and a drive assembly on one side of the rotating chamber; two parallel shredding blade shafts are rotatably mounted inside the shredding box, with shredding blades fitted on the two shafts, a transmission box connected to the left side of the shredding box, a shredding box inlet and a shredding box outlet respectively on the upper and lower sides of the shredding box, the top of the shredding box penetrating the flat plate, with the shredding box inlet located directly below the feeding port; a feeding hopper is provided at the top of the screening box, a sieve plate is provided inside the screening box, the left end of the sieve plate is rotatably connected to the inner wall of the screening box via a hinge, and a vibration assembly is provided below the right end of the sieve plate.

[0007] Preferably, the vibration component includes a cam, the right end of which is connected to a cam shaft, and the cam shaft is rotatably connected to the screening box.

[0008] Preferably, a discharge port is connected through the right side wall of the screening box, the screen plate is placed at an angle with its left end higher than its right end, the right end of the screen plate extends into the discharge port, a retaining ring is fitted on the cam shaft, and the right end of the cam shaft extends out of the screening box.

[0009] Preferably, the left ends of the two crushing blade shafts extend into the transmission box and are respectively connected to the transmission gears, the transmission gears on the two crushing blade shafts mesh with each other, and the right end of one of the crushing blade shafts extends out of the crushing box.

[0010] Preferably, the frame is equipped with a second motor, and the output end of the second motor is connected to a first belt and a second belt respectively. One end of the first belt is connected to the cam shaft, and one end of the second belt is connected to the crusher shaft.

[0011] Preferably, the inner wall of the crushing chamber is further provided with a fixed blade assembly, which includes a first fixed blade and a second fixed blade. The second fixed blade is larger than the first fixed blade and is located below the first fixed blade.

[0013] Preferably, the frame has guide wheels on the bottom left side and support legs on the bottom right side, and the frame and the plate are connected by support rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] No more manual unpacking and feeding are required. Only one person is needed to move the bales to the rotating hopper. The material passes through the feeding port, crushing box, and screening box in sequence, thus achieving automatic conveying and bale breaking. This solves the problem of high manual labor intensity and reduces labor costs. The crushing blades rotate in the opposite direction to break the bales. The fixed blade assembly on the inner wall ensures that the bales near the inner wall of the crushing box can be effectively broken, thereby improving the bale breaking and crushing efficiency. The material that passes through the screening box falls to the bottom of the screening box for collection, while the material that passes through the screening box is discharged from the discharge port along the inclined direction of the screen plate. The integrated conveying operation of feeding, bale breaking, crushing, and screening realizes continuous automated production. Attached Figure Description
