Abstract
An auxiliary device for replacing a bearing of a double-disc furrow opener mainly comprises a top rod, a support frame, a top head, a nut and a rubber ring. The nut is welded on the support frame and is coaxial with the support; the ejector rod is connected with the nut through threads, one end of the ejector rod is spherical and is embedded in the ejector head, the rubber ring is positioned in the groove in the ejector head, and the inner diameter of the rubber ring is smaller than the outer diameter of the ball head of the ejector rod, so that the ejector rod can be prevented from falling off from the ejector head; when the device is used, the support frame is fixedly connected on the bearing seat through a bolt, the end surface of the top end is tightly attached to the end surface of the shaft, the top rod is rotated by using a tool such as a wrench, the support frame is driven to move outwards through thread matching, and therefore the bearing is separated from the shaft; the invention effectively utilizes the existing parts of the double-disc furrow opener and solves the problem of difficult bearing disassembly through a simple structure.
Description
The technical field is as follows:
the invention relates to an auxiliary tool used when a bearing is replaced by a double-disc furrow opener of a no-tillage seeder, in particular to an auxiliary device for replacing the bearing of the double-disc furrow opener.
Background art:
the present widely used double-disc furrow opener of no-tillage planter is because working in the field throughout the year, when the furrow opener crosses uneven place or stone, the bearing can receive serious destruction, use after a period of time, if not change the bearing in time, can lead to the whole scrapping of double-disc furrow opener. The bearing needs to be detached from the rotating shaft in the field replacement process, no special tool is used in the whole detachment process, an operator uses a hammer, a crow bar and the like to hammer and pry, the bearing seat is in close contact with the seeding disc, the common wheel puller does not have an acting point, the whole detachment process consumes a large amount of time of the operator, and finally, the operator can only take violence to detach the bearing seat and destroy other parts of the double-disc furrow opener.
The invention content is as follows:
the invention aims to provide an auxiliary tool used when a bearing of a double-disc furrow opener of a no-tillage seeding machine is replaced.
The purpose of the invention is realized by the following technical scheme:
an auxiliary device for replacing a bearing of a double-disc furrow opener mainly comprises a top rod, a support frame, a top head, a nut and a rubber ring. The nut is welded on the support frame and is coaxial with the support; the ejector rod is connected with the nut through threads, one end of the ejector rod is spherical and is embedded in the ejector head, the rubber ring is positioned in the groove in the ejector head, and the inner diameter of the rubber ring is smaller than the outer diameter of the ball head of the ejector rod, so that the ejector rod can be prevented from falling off from the ejector head; the ejector rod and the ejector head are matched to form spherical matching, and when the axis of the bearing is not perpendicular to the end face of the matched shaft, the end face of the ejector head can also be completely attached to the end face of the shaft, so that the shaft is prevented from being damaged; when the device is used, the support frame is fixedly connected on the bearing seat through a bolt, the end surface of the top end is tightly attached to the end surface of the shaft, the top rod is rotated by using a tool such as a wrench, the support frame is driven to move outwards through thread matching, and therefore the bearing is separated from the shaft; the invention effectively utilizes the existing parts (the bolts for connecting the ditching disc and the bearing seat) of the double-disc ditcher, and solves the problem of difficult bearing disassembly through a simple structure.

FIG. 2 is a half sectional view of the present invention taken along a plane passing through the axis of the rotating shaft;
FIG. 3 is a plan sectional view of the plug taken along the axis of the spindle;
FIG. 4 is a schematic view of a double disc furrow opener configuration.
In the attached drawing, 1 is a mandril, 2 is a support frame, 3 is a mandril, 4 is a nut, and 5 is a rubber ring.
Detailed Description
The invention is further described with reference to the accompanying drawings:
as shown in figures 1-4, the auxiliary device for replacing the bearing of the double-disc furrow opener mainly comprises an ejector rod (1), a support frame (2), an ejector head (3), a nut (4) and a rubber ring (5). The nut (4) is welded on the support frame (2) and is coaxial with the support; the ejector rod (1) is connected with the nut (4) through threads, one end of the ejector rod (1) is spherical and is embedded in the ejector head (3), the rubber ring (5) is positioned in a groove in the ejector head (3), and the inner diameter of the rubber ring (5) is smaller than the outer diameter of a ball head of the ejector rod (1), so that the ejector rod (1) can be prevented from falling off from the ejector head (3); the ejector rod (1) and the ejector head (3) are matched and belong to spherical surface matching, so when the axial line of the bearing is not vertical to the end surface of the matched shaft, the end surface of the ejector head (3) can be completely attached to the end surface of the shaft, and the shaft is prevented from being damaged; when the device is used, the support frame (2) is fixedly connected on the bearing seat through a bolt, the end surface of the ejector head (3) is tightly attached to the end surface of the shaft, the ejector rod (1) is rotated by using tools such as a wrench and the like, and the support frame (2) is driven to move outwards through thread matching, so that the bearing is separated from the shaft; the invention effectively utilizes the existing parts (the bolts for connecting the ditching disc and the bearing seat) of the double-disc ditcher, and solves the problem of difficult bearing disassembly through a simple structure.
