Abstract
The utility model relates to a new variable speed device for peanut and corn spot seeder, which could effectively solve the problems of variable speed of the spot seeder in order to adjust planting distance and save seeds. The solution technical plan is that: a gear shaft and a transmission shaft are equipped inside the shell; variable speed gear is arranged on the gear shaft; a clutch and a transmission chain wheel are equipped on the transmission shaft; the over clutch gear engages with the variable speed gear; the clutch is equipped with threshold handle and the threshold slot is on the shell opposite the threshold handle. The utility model has the advantages of simple structure, uniqueness, novelty, convenient installation and usage, wide adjustment range, good usage effect, spot seeding quality and working efficiency improvement and bright prospect of development and application.
Description
One, technical field
The utility model relates to a kind of speed change gear, the speed change gear that particularly a kind of peanut corn planter is used.
Two, background technology
Speed change gear is often to have on the various machines, and is indispensable device.But present existing peanut corn planter, as application number: 93202689.3 peanut corn planter does not have on it establishes special gear, the change of its spacing in the rows realizes by changing transmitting gear, the replacing of gear not only bothers, inconvenience, and also adjustable range is narrow, the waste seed, operating efficiency and program request quality all are subjected to great influence, and be incompatible with the agricultural machinery modernization, the plantation of unfavorable peanut corn and high yield good harvest.
Three, utility model content
At above-mentioned situation, the purpose of the utility model just provides the speed change gear that a kind of novel peanut corn planter is used, the speed change that can effectively solve planter is beneficial to regulate spacing in the rows, save the problem of seed, the technical scheme of its solution is that gear shaft and power transmission shaft are housed in the shell, change-speed gearing is housed on the gear shaft, clutch and drive sprocket are housed on the power transmission shaft, the excessive gear of the clutch of clutch is meshed with change-speed gearing, the gear handle is housed on the clutch, and on the gear handle respective side shell shift slot is arranged, the utility model is simple in structure, novel unique, easy to install, regulate face width, result of use is good, can improve program request quality and operating efficiency greatly, development prospect light.
Four, description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is an A-A profile among Fig. 1 of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By shown in Figure 1, the utility model is, gear shaft 2 and power transmission shaft 9 are housed in the shell 13, change-speed gearing 1 is housed on the gear shaft 2, clutch 11 and drive sprocket 5 are housed on the power transmission shaft 9, the excessive gear 4 of the clutch of clutch is meshed with change-speed gearing 1, and the gear handle 8 that stretches out shell is housed on the clutch, and on the gear handle respective side shell shift slot 10 is arranged.
For easy to use and assurance result of use, shock mount pull bar 12 on the shell 13, the spring pull bar is equipped with extension spring 7 through fixed body on the pull bar and the fixed body on the shell, on housing outer spring pull bar 12 loosening and tightening wheel 6 is housed.
During use, the utility model is contained on the planter frame, the sowing axle that planter is sowed in the storehouse is connected with gear shaft 2, or by sowing directly replacement gear shaft of axle, drive sprocket 5 links to each other with hinge wheel or minor sprocket 3 on the planter land axle through chain 14 and loosening and tightening wheel 6, its transmission situation is, the planter land wheel rotates and drives big or minor sprocket 3 rotations, driving drive sprocket 5 through chain 14 rotates, drive sprocket 5 drives the excessive gear 4 of coaxial clutch and rotates, the change-speed gearing 1 that is meshed with it again rotates and gear shaft 2 rotates, thereby drive the sowing arbor wheel work of planter, realize the function of program request, loosening and tightening wheel 6 is used to regulate the degree of tightness of chain 14, makes chain be in good working order.
For the needs of multiple spacing, said change-speed gearing 1 is 6 gears of the diameter that varies in size formations that be stacked successively, the 12 grades of speed governing of formation that match with big or pinion on the planter land axle, and speed governing is flexible, wide ranges, result of use is good.For easy to install, arrangements for speed regulation shell 13 bottoms are hollow body (both not had has base plate).
It should be appreciated that the utility model both can be used for the peanut corn planter, similarly need on the machine or device of speed change applicable to other again, no matter where be used for, as long as adopt this speed change gear all to belong to protection domain of the present utility model.
