Technical field
The utility model relates to maize harvesting machine technical field, the threshing cylinder that relates in particular to the threshing tooth using on a kind of maize harvesting machine and use this threshing tooth.
Background technology
At present threshing tooth mainly contains three types: a kind of is plate cutter tooth, captures and to curry flailing action strong, and it is better that crop feeds when inhomogeneous adaptability, but larger to corn kernel injury; A short and thick conical tooth, less to corn kernel injury, but threshing efficiency is lower; Be a threshing fluted disc, strike threshing ability is stronger, and threshing efficiency is higher, but reliability is lower.During above-mentioned three kinds of threshing tooths work, require corn kernel moisture content to be less than 18%, if moisture content is higher than this level, will greatly increase the percentage of damage of seed; The threshing cylinder being applied on combine mainly contains three types: a kind of is nail tooth drum, has stronger Grasping skill, and crop feeds strong adaptability when inhomogeneous, and threshing ability is strong; A drum with rasp bars, threshing better performances, but that crop feeds when inhomogeneous adaptability is poor, easily stops up cylinder; Be a bar dental roller, by fashion of extrusion, corn ear squeezed to broken and seed threshing, threshing better performances, percentage of damage is lower; The working performance of nail tooth drum and drum with rasp bars is stable, but all has the problem that seed damage rate is high, and the threshing tooth of bar dental roller is quarter butt tooth, belong to machined piece, upper end is spherical cylinder, and lower end is by Screw assembly on ratch, and its manufacture difficulty is larger, power drain is large, production and application cost is higher, and existing barrel is spliced, by multi-sheets, is spliced to form, manufacture difficulty is large, and dependability is poor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of threshing tooth is provided, and it manufactures simple, uses reliably, and Threshing is good.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of threshing tooth, comprise columniform ratch, the top of described ratch is that bulb is cylindrical, described ratch bottom is provided with herringbone base, described ratch bottom is positioned at the peak of described herringbone base, and described ratch is relatively set with two reinforcements, the whole described threshing tooth structure that is formed in one.
As a kind of improvement, the two ends on described herringbone base are respectively equipped with installing hole.
Owing to having adopted technique scheme, the top of ratch is that bulb is cylindrical, can prevent seed damage, and by being provided with reinforcement, guarantee the fastness of ratch, make the length of ratch can design longer, increase the working application time of ratch, thereby strengthen Threshing and ability, threshing tooth is provided with herringbone base, guarantee the fastness that threshing tooth is connected with barrel, and the threshing tooth integral body structure that is formed in one, comparatively simple on manufacturing, can reduce costs, during use, threshing tooth impacts in corncob, seed is come off and make corncob constantly rotate and realize threshing with the notch board rubbing of maize harvesting machine, power drain is little.
Because the two ends on described herringbone base are respectively equipped with installing hole, apply this installing hole and can realize removably connecting of threshing tooth and threshing cylinder, facilitate follow-up maintenance work.
Technical problem to be solved in the utility model is: a kind of threshing cylinder is provided, and it manufactures simple, uses reliably, and Threshing is good.
A threshing cylinder, comprises barrel, and described barrel is provided with the threshing tooth of said structure.
Owing to having adopted the threshing tooth of said structure, so this threshing cylinder Threshing is good, uses reliable.Barrel can adopt the mode directly welding together to be connected with threshing tooth, also can adopt following structure to connect.
As a kind of improvement, described barrel is provided with the threshing toothholder matching with described herringbone base, and described threshing tooth is arranged on described threshing toothholder by screw bolt and nut; By said structure, can make threshing tooth and barrel removably connect, convenient for maintaining.
As a kind of improvement, described nut-welding is on described threshing toothholder.
As a kind of improvement, the week of described barrel is upwards evenly provided with the described threshing tooth that some rows arrange vertically, and the quantity of every row's threshing tooth is identical, two adjacent row's threshing tooth interlaced arrangement.
As a kind of improvement, described barrel is integral type, and the outer peripheral face of described barrel is cylindrical; Barrel is the rigidity that can make barrel and the strength increase of integral type, and sealing is improved, and while making to rotate, surrounding air formation eddy current is little, reduces power consumption.
As a kind of improvement, in described barrel, be welded with at least two for the width dish of back-up roller cylindrical shell.Width dish can make the intensity of barrel increase, and can mounting rotary drum axle by width dish.
