The threshing machine has a small size, light weight, simple structure, high working efficiency, great threshing effect, reliable security and convenient usage, being suited for the farmer who grows plant in small scale.
Description
The utility model belongs to the thresher machine technical field of structures in the agricultural machinery.
The thresher machine of prior art, mostly be at the threshing cylinder outer surface " V " sections silk pawl is set, arrest the straw afterbody with staff, fringe is deployed on threshing cylinder, and threshing cylinder is laid the fringe grain by the iron wire pawl in rotation process, this thresher inefficiency, threshing is unclean, and dangerous big, does not have slightly very will injure staff; Though it is to be with the whole straw of fringe all to feed in the feed well that some threshers are also arranged; carry out grain, grass separation after the threshing; can not injure staff again; operating efficiency is also higher; but its complex structure, bulky, price is more expensive, power is required also higher, for minute common peasant household of family plantation; little practical, mainly be that price is too high, carrying is inconvenient and it is inconvenient to connect electricity.
The purpose of this utility model provides in order to solve deficiency of the prior art just that a kind of safety, threshing are effective, high efficiency, simple in structure, volume is little, in light weight, low price, connect electricity and wipe the pressure type thresher easily.
The purpose of this utility model is achieved by the following technical solution.
This wiping pressure type thresher is that the outer surface at threshing cylinder is provided with tooth bar vertically, also is provided with a stationary rack that parallels with tooth bar on the threshing cylinder in the feed hopper bottom, is provided with screen cloth at grain export.
The tooth bar that is arranged on the threshing cylinder is 3～15, and these tooth bars are uniform along the circumference equal angles of cylinder; Tooth bar and stationary rack on the threshing cylinder are spur rack; Tooth bar on the threshing cylinder can be set in rotating with cylinder to intersect engagement mutually with stationary rack, during engagement, leaves the gap between the tooth of two tooth bars; Also can be set to two tooth bars and not intersect engagement, between the tooth top of two tooth bars at a distance of best 8～18mm; The tooth bar that is arranged on the threshing cylinder is installed on the cylinder with screw, and this tooth bar is replaceable; Stationary rack is installed on the frame with screw, and this tooth bar is also replaceable.
After the feed hopper adding, the threshing cylinder that tooth bar is housed matches with stationary rack in rotation process the straw of band fringe, and crowded wiping drops on the straw of feed hopper bottom, the fringe grain on the straw is squeezed wipe; Also available hand is arrested the straw afterbody, only fringe portion is reached the feed hopper bottom, the crowded wiping by two tooth bars with the fringe grain squeeze wipe after, again the straw after the threshing is thrown.The fringe grain of taking off falls from outer casing bottom by screen cloth and enters the groove that connects material, and the centrifugal force when the careless slag that is blocked by screen cloth rotates with threshing cylinder is along the grass outlet shell that flies out.
The tooth bar that is arranged on the threshing cylinder is advisable with 3～15, tooth bar very little, threshing efficiency is not high, tooth bar is too many, increases complex structure degree, weight and the manufacturing cost of thresher; Tooth bar is uniform along the circumference equal angles of threshing cylinder, mainly is the stability during for the gravity balance that keeps threshing cylinder and work; Tooth bar on the threshing cylinder and stationary rack adopt the comparatively simple spur rack of structure can reach threshing effect preferably; Tooth bar on the threshing cylinder can be set in rotating with cylinder to intersect engagement mutually with stationary rack, during engagement, leaves the gap between the tooth of two tooth bars; Also can be set to two tooth bars and not intersect engagement, at this moment, between the tooth bar on the threshing cylinder and the tooth top of stationary rack preferably at a distance of 8～18mm, the gap is too little, and two tooth bars easily collide mutually and damaged, and the gap is too big, it is too little to squeeze the strength of wiping the fringe grain, can reduce the threshing effect again; The tooth bar that is arranged on the threshing cylinder is installed on the cylinder with screw, and stationary rack also is installed on the frame with screw, makes tooth bar more easily change, and the one, be convenient to repair, the 2nd, can adjust the tooth bar of changing different size according to the particle size of the crop of institute's threshing.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is the A-A cutaway view that the utility model master looks,
Fig. 2 is the B-B cutaway view that the utility model is overlooked,
Fig. 3 is a left view of the present utility model,
Fig. 4 is two a tooth bars intersection position engaged schematic diagram.
At first as Fig. 1～shown in Figure 3, make frame 3 with angle steel respectively, stationary rack 9 is installed on the crosspiece 14 of frame 3, make threshing cylinder 4 with steel plate, on threshing cylinder, be symmetrical arranged four toothed rack 8, tooth bar 8 and stationary rack 9 can be installed on respectively on the crosspiece 14 of threshing cylinder 4 and frame with screw, and tooth bar is replaceable; As not changing, also can be with the fixing welding of tooth bar; The main shaft 11 of threshing cylinder 4 is installed on the frame 3, the main shaft 11 of threshing cylinder drives by motor 1, the shell of bringing hopper 5 into 2 that to make is in advance then set up, the bottom of shell 2 is provided with curved screen 10, be provided with the groove 12 that connects material below the screen cloth 10, the groove 12 that connects material is sent pellet from the side of thresher; The afterbody relative with feed hopper is grass outlet 7 to be opened/closed on the shell.Tooth bar 8 on the threshing cylinder can be set in rotating with cylinder to intersect engagement mutually with stationary rack 9, during engagement, leaves the gap between the tooth of two tooth bars, as shown in Figure 4; Also can be set to two tooth bars and not intersect engagement, at this moment, between the tooth bar on the threshing cylinder and the tooth top of stationary rack preferably at a distance of 8～18mm, as shown in Figure 2.During work, the door 13 of grass outlet 7 is opened, starter motor 1, driving threshing cylinder 4 rotates, reinforced from feed hopper 5, when reinforced, the whole straw of band fringe all can be added, also can a fringe portion reach the loading hopper bottom, arrest the afterbody of straw with hand straw, threshing cylinder 4 is when clockwise rotating, tooth bar 8 and stationary rack 9 effect of matching squeeze and wipe the fringe grain, make the fringe grain break away from straw, the fringe grain of taking off, is dished out along grass outlet 7 by the centrifugal force of threshing cylinder by the slag grass that screen cloth blocks by falling into the groove 12 that connects material from the screen cloth 10 of outer casing bottom.This thresher can be used for the threshing of crops such as paddy, wheat, beans, according to the size of the crop grain of institute's threshing, adjusts the tooth bar of changing different size and the screen cloth of different size mesh and gets final product.
This thresher volume is little, and is in light weight, simple in structure; high efficiency, threshing is effective, and is safe and reliable; safeguard simply processing ease, low price; according to the difference of configuration motor, only 500～1200 yuan of every prices, less demanding to power; available 1～3 kilowatt monophase machine, three phase electric machine, 1.5 horsepowers small gasoline engine or 3 horsepowers little diesel engine drive; use very conveniently, the peasant household that is particularly suitable for casual household plantation uses, and especially the relatively poor farmers in mountain area of tillage condition is used.
