Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a movable straw film wrapping machine. Background Art

[0002] At present, the main methods for processing crops such as straw include burning, crushing and returning to the field, industrial materials, feed, etc. However, most of the straw is processed by burning, which not only wastes straw resources but also pollutes the environment. Therefore, agricultural machinery is needed that can fully convert straw resources into livestock feed resources.

[0003] The straw used in animal husbandry is mainly used to make feed, and how to store straw has always been a key issue. At present, in some areas in northern my country, such as the Northeast, machines are used to break up the straw, and then the broken structure is pressed into short-column straw bales, and then the short-column straw bales are coated with straw coating machines. Since the coated straw bales are sealed, when the pH value in the bales drops to about 4.2, the growth of microorganisms is inhibited, so that the straw can be stored for a long time, and it is also convenient to take and transport.

[0004] At present, the existing straw film wrapping machine cannot move autonomously. When the film wrapping machine is needed, it is transported to the designated location of the field by a tractor and then unloaded. After the straw is packaged at the designated location, the straw at the next location needs to be filmed, so it needs to be transported to the next location, and the film wrapping machine needs to be lifted up by a tractor again and then transported to the next location. Sometimes, the two locations where straw film wrapping is needed in the field are not far apart, and the method of repeatedly transporting the film wrapping machine to the corresponding location by a tractor is very inconvenient and time-consuming.

[0005] In addition, the base of the existing straw wrapping machine is relatively small to reduce weight and facilitate tractor transportation. However, the land in the field is relatively rugged and uneven. When the straw wrapping machine is used for wrapping, the straw wrapping machine is prone to shaking or even tilting and overturning.

[0006] Therefore, based on the shortcomings of the existing straw wrapping machine according to the feedback from customers, the inventor made improvements according to the proposed defects to overcome the above problems. Utility Model Content

When the film wrapping is not started, the cutting arm 36 is placed parallel to the upper surface of the turntable. The cutting arm 36 presses one end of the film cloth underneath it, thereby unfolding the film cloth on the film wrapping roller 4. When the film wrapping starts, the motor B25 is started, the turntable rotates, and the cutting arm 36 moves upward without pressing the film cloth. At the end of the film wrapping, the cutting arm 36 moves downward, cuts off the connection of the excess film cloth, and presses one end of the film cloth again to complete the film wrapping of a straw bale.

[0069] The present invention creates a movable straw film wrapping machine. When working, the motor A37 is started, and the motor A37 drives the large gear 9 on the cross bar 16 to rotate through the pulley transmission, so that the rotation of the large gear 9 drives the two rear wheels 2 to rotate, and the two bent handles B7 on the rear of the frame 1 are held by manpower, and the direction can be controlled by the handle A5 in front of the straw film wrapping machine to realize the forward movement of the straw film wrapping machine; when arriving at the destination, the parking rod 8 set at the rear of the frame 1 is pushed toward the ground, and the parking rod 8 is against the ground, so that the straw film wrapping machine is parked on the uneven ground; the rotating disk 15 on the rotating support seat 6 is extended to the ground by the two telescopic support rods 12, until the four station frames 18 on the bottom plate 17 are against the ground. On the surface, it can assist the mobile straw film wrapping machine to be stably placed on the ground; when the bale position of the baled straw is reached, the bale is placed on the turntable, and the motor B25 is started. The motor B25 drives the gear B24 connected thereto to rotate, and then drives the large disc 21 meshing with the gear B24 to rotate. Through the ball bearing A19 and the ball bearing B23, the large disc 21 rotates to rotate the central shaft 22, thereby driving the bevel gear A30 to rotate, and the bevel gear B3124 meshing therewith rotates, driving the transmission rod 28 to rotate, and the driving gear 33 connected to the transmission rod 28 rotates. Through the chain transmission, the two driven gears 34 drive the rollers 27 to rotate, so that the film cloth is evenly wrapped on the straw bale during the rotation of the turntable;

[0070] The mobile straw film wrapping machine designed in this scheme is designed with a frame 1 structure to realize the function of walking and moving. The motor A37 drives the two rear wheels 2 to rotate, so that the straw film wrapping machine can be moved to the designated film wrapping position. Compared with using a tractor to assist transportation, it is more convenient and saves time; the film cloth structure and the front wheel 3 are designed as an integrated molding, making the overall structure of the straw film wrapping machine simpler; due to the steep and uneven ground of the field, the base of the ordinary straw film wrapping machine is small, which will cause the film wrapping machine to tilt and shake, which is likely to cause the straw bale to fall, or the film cloth to fall after filming. Loose, etc., aiming at the stability of the mobile straw wrapping machine on the field road, a parking rod 8 and a support seat 6 are designed. The parking rod 8 is designed at the rear wheel 2 position of the straw wrapping machine. The parking rod 8 is pushed downward, and the bottom end of the parking rod 8 is inserted into the ground to stop the straw wrapping machine. At the same time, the four station frames 18 on the bottom plate 17 are propped against the ground by using the support seat 6 that can be extended and retracted up and down, so as to assist the straw wrapping machine to be stably placed on the ground; at the same time, the frame 1 structure designed in this scheme increases the overall frame structure of the straw wrapping machine, so that its chassis is more stable during the wrapping process.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
