Description

Technical field:

[0001] The utility model relates to the technical field of gourd machines, in particular to a detachable gourd-removing tooth structure for gourd machines. Background technology:

[0002] At present, gourd harvesters are mainly used for the harvesting of seeds of melons such as gourds, melons, and seed melons. During the harvesting process, the front header mechanism is mainly used for harvesting. The melon picking shaft of the header mechanism has multiple melon picking teeth. When the melon picking shaft rotates, the gourds are picked up by the melon picking teeth and removed by the melon stripper during the rotation process. The dropped gourds roll into the collection bin at the rear. For example, the patent application with publication number CN201957460U discloses a melon harvester, in which the melon stripper includes a plurality of melon stripping racks, and the melon stripping racks and the melon stripping teeth are staggered. The current melon stripping racks are welded and fixed to the crossbeam of the frame one by one. This single-root structure has low strength and is easily deformed after being stressed. If local damage occurs, the welding part needs to be disassembled and replaced with a new melon stripping rack. Due to the small operating space, disassembly and replacement are difficult, which increases the maintenance and use costs.

[0003] In summary, the above-mentioned problems of removing melon teeth in gourd machines have become technical problems that need to be solved urgently in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a detachable melon-removing tooth structure for a gourd machine, which solves the problems of low strength, easy deformation and difficult disassembly and replacement of the previous melon-removing teeth.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A detachable melon-peeling tooth structure for a gourd machine comprises a frame, a crossbeam is installed on the frame, and a plurality of melon-peeling tooth assemblies are installed on the crossbeam in parallel and at intervals by bolts. The melon-peeling tooth assembly comprises a tooth seat, and the tooth seat is welded by a transverse support plate and a longitudinal support plate, two melon-peeling teeth are welded at intervals on a side of the longitudinal support plate away from the transverse support plate, a reinforcing rib plate is welded on the lower side of the melon-peeling tooth along the length direction, the top end of the reinforcing rib plate passes through the longitudinal support plate and is welded and fixed to both sides of the transverse support plate, and the transverse support plate and the longitudinal support plate are fixedly connected to the crossbeam by bolts respectively.

[0007] The two sides of the transverse support plate are provided with clamping protrusions, and the reinforcing rib plate is provided with clamping grooves matched with the clamping protrusions.

[0008] The transverse support plate is provided with a through hole, and the longitudinal bolt passes through the through holes on the crossbeam and the transverse support plate and is locked and fixed in cooperation with a nut.

[0009] The longitudinal support plate is provided with threaded holes, and the transverse bolts pass through the cross beam and are threadedly connected with the threaded holes of the longitudinal support plate.

[0010] The melon-removing teeth are arc-shaped teeth with a hollow interior, and a sealing plate is welded to the bottom of the arc-shaped teeth.

[0011] The utility model adopts the above scheme and has the following advantages:

[0012] By setting a tooth seat, two melon-removing teeth are welded on each tooth seat, and a reinforcing rib plate is provided at the bottom of the melon-removing tooth to increase the strength and prevent deformation under stress. The tooth seat is welded by a transverse support plate and a longitudinal support plate, and the transverse support plate and the longitudinal support plate are fixedly connected to the crossbeam by bolts respectively, thereby realizing a transverse and longitudinal fixed connection. On the basis of ensuring the connection strength, when local damage occurs, the tooth seat and the two melon-removing teeth can be disassembled as a whole for replacement, which facilitates maintenance and reduces costs.
