Description

Technical Field

[0001] The utility model relates to the technical field of furrow openers, in particular to a furrow opener for agricultural machinery. Background Art

[0002] A furrow opener is an agricultural machinery component used to open a furrow on the land. There are two types of existing furrow openers, one is a furrow opener that can only open one furrow on the ground at a time, and the other is a furrow opener that can open multiple furrows on the ground at a time. The furrow opener that can only open one furrow at a time has a low working efficiency, while the furrow opener that can open multiple furrows on the ground at a time has a fixed distance between the furrows opened, and the distance between the furrows cannot be adjusted according to demand. Therefore, in view of the above situation, it is urgent to develop an agricultural machinery furrow opener that can open multiple furrows at a time and is easy to adjust, so as to facilitate adjusting the distance between the furrows according to demand, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0003] The purpose of the utility model is to provide a furrow opener for agricultural machinery to solve the problems raised in the above background technology.

[0004] The technical solution of this utility model:

[0005] The cam is an assembly of a plurality of first and second support rods, each of which is connected to a plurality of linking mechanisms, the first and second support rods being connected in a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the second being connected to a plurality of ways, the

[0006] Beneficial effects of the utility model:

[0007] 1. When the agricultural machinery furrow opener is used, the entire device is connected to the agricultural tractor, and the tractor drives the grooving mechanism to move on the land, and multiple furrow openers are used to open multiple furrows on the land. When adjusting, first pull the handle by hand, and use the handle to pull up the extension plate and the block, so that the extension plate rotates around the shaft sleeve. At this time, the spring is stretched, so that the block moves out of the limit slot, and then the first sliding sleeve and the second sliding sleeve are slid to adjust the position of the furrow opener. After adjustment, release the handle so that the elastic force of the spring drives the extension plate and the block to move down, so that the block is inserted into the limit slot, and then the position of the grooving mechanism is limited. In summary, the utility model can open multiple grooves at one time, and is easy to adjust, so that the distance between the grooves can be adjusted according to needs.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Specific examples are given below.

[0015] See also Figure 1-Figure 3In an embodiment of the utility model, a furrow opener for agricultural machinery includes a frame 1, a connecting frame 2, a first support rod 3, a second support rod 4 and a slotting mechanism 5. The front side of the frame 1 is fixed with a connecting frame 2, and a plurality of mounting holes 201 for bolts to pass through are provided on the connecting frame 2. The connecting frame 2 is fixed to the agricultural tractor by bolts and nuts. The first support rod 3 and the second support rod 4 are fixed in the frame 1, and a plurality of slotting mechanisms 5 are connected between the first support rod 3 and the second support rod 4. The slotting mechanism 5 includes: a first sliding sleeve 501, a second sliding sleeve 502, a furrow opener 503, a connecting plate 504, a shaft sleeve 505, a rotating shaft 506, an extension plate 507, a block 508 and a spring 509.
