This machine integrates baling and wrapping functions, allowing for subsequent wrapping of the bales. It features a compact and reasonable structure, low investment, low cost, time and labor saving, and ease of use.

[0003] This silage round bale wrapping and baling machine is quite large. When moving the machine, a tractor is needed to tow it via the traction arm. When the machine arrives at the site for wrapping and baling, it is necessary to go around the traction arm to prevent it from affecting the loading and unloading of materials and reducing the efficiency of loading and unloading; or the traction arm can be removed, which increases the workload of installation and dismantling. Utility model content:

[0004] To solve the above-mentioned technical problems, this utility model provides a silage wrapping machine. The technical problem it addresses is that the traction arm reduces the efficiency of loading and unloading materials and increases the workload of installation and dismantling. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0008] A connecting arm is located at the lower part of the wrapping device, and the connecting arm is connected to the front end of the frame in a rotating manner;

[0009] The traction arm is connected to the connecting arm by a telescopic structure, and the retraction arm does not affect the unloading of the film wrapping device when it is retracted to the connecting arm.

[0010] Locking structures used to lock the traction arm and connecting arm.

[0011] Furthermore, the frame is equipped with a slewing bearing via a fixed structure, and the frame is connected to one end of the connecting arm via the slewing bearing.

[0012] Furthermore, a partition is installed inside the connecting arm by means of a fixed structure, which divides the interior of the connecting arm into two cavities;

[0013] The traction arm consists of two fixedly connected hollow rods, which are slidably connected to the cavity in a one-to-one correspondence.

[0014] Furthermore, the ends of the two rods furthest from the connecting arm are fitted with hoops in a fixed manner; arc-shaped cavities are respectively opened on the opposite side walls of the two rods inside the hoops, and traction bushings are fixedly installed in the two arc-shaped cavities.

[0015] Furthermore, the locking structure includes pin holes formed in the connecting arm and rod, with a pin shaft provided in the pin holes in a plug-in manner.

[0016] Furthermore, a reinforcing sleeve is fitted at the pin hole at the outer end of the connecting arm, with the pin hole penetrating the reinforcing sleeve.

[0017] Furthermore, a connecting bushing is fixedly installed inside the pin hole of the rod.

[0018] The beneficial effects of this utility model are: the horizontal conveyor is set at the rear of the frame, which increases the loading space; the frame structure of the horizontal conveyor reduces the frame length and the weight of the whole machine; and the loading, bundling and wrapping work is carried out by the arrangement of the lifting conveyor, bundling chamber and wrapping device on the frame.

[0030] A locking structure for locking the traction arm 7 and the connecting arm 6. The locking structure includes a pin hole opened in the connecting arm 6 and the rod 71. The pin hole is provided with a pin shaft 11 in a plug-in structure.

[0031] It should be noted that a reinforcing sleeve 12 is fitted at the pin hole at the outer end of the connecting arm 6, the pin hole passes through the reinforcing sleeve 12, and a connecting bushing 13 is fixedly installed inside the pin hole of the rod 71.

[0032] The traction arm 7 is configured as two parallel rods 71, and is equipped with a partition, a reinforcing sleeve 12, and a clamp 72 to increase rigidity and strength, improve durability and lifespan, avoid deformation caused by the tension of the pin on the connecting arm and traction arm during traction, reduce stress concentration and deformation, and improve stability and safety during traction.

[0033] The working principle and process of this utility model are as follows:

[0034] When traction work is required, pull the pin 11 out of the rear pin hole, then pull the connecting arm 6 forward until the pin hole of the rod 71 is concentric with the pin hole at the front of the connecting arm 6, then insert the rod 71 into the pin hole at the front of the connecting arm 6, insert the traction pin of the traction machine into the traction bushing 10, and then carry out the transfer work.
