Description

Technical Field

[0001] The utility model relates to the technical field of balers, in particular to a guide wheel buffer device for a round baler. Background Art

[0002] When the round hay baler is working, the pick-up spring teeth pick up the hay and transport it to the feeding part. The original guide wheel is only connected by a chain, so the distance between the guide wheel and the spring teeth is fixed. The hay transportation process is in a rigid state and there is no buffer. If you need to adjust the distance between the guide wheel and the spring teeth, you must manually adjust the number of chain connection sections. When the amount of hay is not fixed during the picking process, or the baler travels at an irregular speed, the friction driving force formed by the guide wheel contacting the hay will vary too much, resulting in the inability to fully exert the hay feeding efficiency, which directly affects the operating efficiency and operation stability of the baler. Therefore, it is necessary to design a guide wheel buffer device for round hay balers to solve the above problems. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model aims to provide a guide wheel buffer device for a round baler, so as to control the uniform entry of grass into the machine and thus improve the working efficiency.

[0004] The utility model is realized by the following technical solutions:

[0005] A guide wheel buffer device for a round baler comprises a curved connecting rod, a sliding buckle, a guide wheel, a protective chain and a spring, one end of the curved connecting rod and the sliding buckle are hinged to the same side of a pickup, a sliding column is provided at the middle position of the curved connecting rod and is arranged in cooperation with the sliding buckle, a guide wheel is installed at the other end of the curved connecting rod, and a hinge seat is also provided on the curved connecting rod, which is located between the sliding column and the guide wheel, spring clips are fixed at both ends of the spring, the spring clip at one end is hinged to the hinge seat, and the spring clip at the other end is hung on the protective chain, and one end of the protective chain is hinged to a frame.

[0006] Preferably, the spring clamp fixed to one end of the spring is hinged to the hinge seat by bolts, and the spring clamp fixed to the other end of the spring is hung on the protective chain by bolts and washers.

[0007] Preferably, the middle part of the sliding column is smooth and can slide in the sliding buckle. The end of the sliding column is provided with a thread. A washer is first inserted and then a nut is screwed into the thread to axially limit the sliding buckle.

[0009] Preferably, the initial distance between the spring teeth on the pickup and the guide wheel is set to be suitable for the amount of grass that passes when the machine body moves smoothly.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model replaces the relatively troublesome method of adjusting the number of chain hanging sections by arranging a spring between the original chain and the guide wheel to adjust the distance between the guide wheel and the spring teeth to adapt to picking up different amounts of grass. The spring can play a flexible expansion and contraction role during the operation of the machine. When the amount of grass is not fixed during the picking process, it can always be raised and lowered freely so that the grass is input into the machine under uniform friction resistance at a suitable distance between the guide wheel and the spring teeth. The utility model greatly reduces the difficulty of production, is easy to maintain and use, and improves the working efficiency of the machine and the product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0013] Figure 1 The utility model is a schematic diagram of the structure of the guide wheel buffer device of the round baler.

[0014] Among them, there are a curved connecting rod 1, a sliding buckle 2, a guide wheel 3, a protective chain 4, a spring 5, a pick-up 6, a spring tooth 601, a sliding column 7, an articulated seat 8, a spring clamp 9, a hand pull rod 10, and a washer 11. DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings. Figure 1A guide wheel buffer device for a round baler is shown, comprising a curved link 1, a slide buckle 2, a guide wheel 3, a protective chain 4 and a spring 5. One end of the curved link 1 and the slide buckle 2 are hinged to the same side of a pick-up 6. The pick-up 6 is provided with a spring tooth 601. In order to make the curved link 1 move only in the vertical direction, a slide column 7 is provided at the middle position of the curved link 1 and is cooperated with the slide buckle 2. The guide wheel 3 is installed at the other end of the curved link 1. The curved link 1 is also provided with an articulated seat 8, which is located between the slide column 7 and the guide wheel 3. Spring clips 9 are fixed at both ends of the spring 5. The spring clip 9 at one end is hinged to the articulated seat 8, and the spring clip 9 at the other end is hung on the protective chain 4. One end of the protective chain 4 is hinged to the frame. By arranging a spring 5 between the protective chain 4 and the guide wheel 3, the distance between the guide wheel 3 and the spring tooth 601 is adjusted to adapt to the picking of different amounts of grass. The spring 5 can play a flexible expansion and contraction role during the operation of the machine. When the baler is moving at an uncertain speed causing changes in the amount of grass fed, or when the amount of grass is not fixed during the picking process, the spring 5 can always be raised and lowered freely, so that the grass maintains a suitable distance between the guide wheel 3 and the spring tooth 601 on the pickup 6 and is input into the machine under uniform friction resistance, thereby improving the operating efficiency of the baler.

[0017] In order to keep the spring 5 elastic in the vertical direction, a spring clip 9 is used for limiting the position. At this time, the spring clip 9 fixed at one end of the spring 5 is hinged to the hinge seat 8 by bolts, and the spring clip 9 fixed at the other end of the spring 5 is hung on the protective chain 4 by bolts and washers 11.

[0018] It can be seen that the spring 5 is arranged between the protection chain 4 and the guide wheel 3. Due to the flexible expansion and contraction of the spring 5, the small displacement of the guide wheel 3 in the vertical direction can be enhanced. In addition to this method, it is also conceivable to improve the curved link 1 installed with the guide wheel 3 to enhance the above effect. The middle part of the sliding column 7 is set to be smooth enough to slide freely in the sliding buckle 2. The end of the sliding column 7 is provided with a thread. The washer 11 is first inserted and then a nut is screwed into the thread to limit the sliding buckle 2 axially.

[0019] When the initial distance between the guide wheel 3 and the spring tooth 601 needs to be manually adjusted, a manual control operation is performed by welding a hand pull rod 10 on the curved connecting rod 1 .

[0020] It is worth mentioning that when the baler travels at an irregular speed, the amount of grass fed changes. Generally, excluding the case where the amount of grass fed is small, it can be considered that the amount of grass fed when the machine body travels steadily is the minimum amount of grass. The initial distance between the spring tooth 601 on the pickup 6 and the guide wheel 3 ( Figure 1 The mark d) in the middle is set to be suitable for the amount of grass that passes when the machine body moves steadily, so that when the travel speed of the baler changes, the distance between the guide wheel 3 and the spring tooth 601 can be increased by adjusting the spring 5 to keep the grass receiving uniform friction resistance.

[0021] The working principle of this utility model:

[0022] like Figure 1 The utility model includes a curved connecting rod 1, a sliding buckle 2, a guide wheel 3, a protective chain 4 and a spring 5. Both ends of the spring 5 are installed in a spring clamp 9. When the grass is fed into the picker 6, the spring teeth 601 thereon and the guide wheel 3 together control the grass to enter the machine evenly, thereby improving the working efficiency. Since the production cost of adding a spring is low, when the machine is working in the field, it can effectively adapt to the change of grass amount in the field, effectively improve the working efficiency, and maximize the economic benefits of the baler. It has been unanimously recognized by users and is very worthy of promotion in the industry.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
