Description

Herbicide weapons {SPRAY DEVICE FOR HERBRICIDE}

The present invention relates to a herbicide sprayer spraying by spraying the herbicide on the farmland while driving the farmland by the towing vehicle, more specifically, pumping operation by the rear output shaft of the towing vehicle towing the agricultural trailer, It is related with the herbicide atomizer which supplies to a nozzle stand.

Generally, drugs such as liquid herbicides and fertilizers are sprayed onto farmland while being transported in towing vehicles such as tractors and tillers. That is, the tow vehicle sprays the medicine while transporting the medicine and traveling on farmland. This medicine is sprayed while being sprayed by the towing vehicle and the herbicide sprayer installed in the trailer towed by the towing vehicle.

As shown in FIG. 1, the herbicide sprayer includes a medicine tank MT provided in the tow vehicle T; A pumping part S fixed to the frame F of the trailer TR; It includes; a nozzle unit 20 for spraying the medicine is supplied from the pumping unit (S).

At this time, as shown in FIG. 2, when the rear output shaft A of the tow vehicle T rotates, the pumping part S rotates while the driving pulley 12 mounted to the rear output shaft A rotates. (13) and the driven pulley 14 of the pump 10 are rotated. As a result, the rotating shaft 10a of the pump 10 rotates, thereby pumping the pump 10. Therefore, the pump 10 supplies the medicine of the medicine tank MT to the nozzle stand 20, and the nozzle stand 20 sprays the medicine supplied to the farmland.

Here, the medicine tank MT may be installed in the tow vehicle T, as shown, or alternatively, may be installed in the trailer TR. In addition, the nozzle unit 20 may be installed in the trailer TR, as shown, alternatively, may be installed in the tow vehicle T.

At this time, the trailer TR may be a rotor (R) for cultivation, or a vinyl coating machine (V) for coating vinyl on farmland, as shown in FIG.

However, the pumping part S of the herbicide sprayer, as shown in Figure 2, the leg (L) formed in the lower portion of the pump 10 is fixed to the frame (F) by welding, the drive pulley 12 And the driven pulley 14 and the belt 13 connecting them, there is a problem in that it can not be separated from the frame (F). Therefore, since the pumping part S is always exposed to the outside even in the period which does not spray a chemical | medical agent, a failure arises in a short period.

In addition, since the pump 10 is not separated, when the pump 10 is installed in the rotor R as shown in FIG. 1, the rotor R must be mounted to the tow vehicle T in order to spray the chemicals. do. That is, the pump 10 cannot be installed in the vinyl coating machine V as shown.

In addition, as the belt 13 is directly connected to the drive pulley 12, there is also a problem that the pump 10 is operated even when no medicine is sprayed. That is, when the rear output shaft A of the tow vehicle T rotates, there is a problem that the pump 10 operates unconditionally. Of course, in order to prevent this, the belt 13 may be removed and stored separately. However, in this case, the problem of frequently losing the belt 13 occurs.

The present invention has been devised to solve the conventional problems as described above, can be mounted or separated on the tow vehicle or trailer as needed, and can control the operation of the pump even if the rear output shaft of the tow vehicle rotates The purpose is to provide a herbicide atomizer with a pumping section.

On the contrary, an object of the present invention is a drive gear 210 that is integrally mounted to the rear output shaft (A) of the towing vehicle (T) and rotates; A driven gear 220 which is rotated by the drive gear 210 and on which one side the drive pulley 222 is integrally mounted; It has a driven pulley 244 that is rotated by the drive pulley 222 of the driven gear 220, the rotating shaft 121 is coupled to the driven pulley 124 to perform the pumping operation by the rotation of the driven pulley 124. And, the pump 240 for supplying the medicine of the medicine tank (MT) to the nozzle unit 20; A belt 250 wound around the driving pulley 222 of the driven gear 220 and the driven pulley 244 of the pump 240; And a base 260 integrally mounted to one side of the driven gear 220 and the pump 240 and detachably fixed to the trailer TR or the towing vehicle T. Achieved by a herbicide atomizer.

At this time, the idler for selectively idling the driven pulley 124 of the pump 120; may further include. In addition, interposed between the drive gear 210 and the driven gear 220, at least one electric gear 215 for transmitting a driving force of the drive gear 210 to the driven gear 220; It may be.

Here, the idler is interposed between the rotary shafts 121 and 241 and the driven pulleys 124 and 244 of the pumps 120 and 240, for example, and the driven pulleys 124 and 244 are connected to the rotary shafts 121 and 241. A bearing 142 for allowing idle rotation; A boss 144 protruding from the driven pulleys 124 and 244 in the same central portion and disposed outside the rotation shafts 121 and 241 of the pumps 120 and 240; And selectively binding the boss 144 and the rotation shafts 121 and 241 to selectively transmit the rotational force of the driven pulleys 124 and 244 to the rotation shafts 121 and 241. .

A sleeve 145 rotating in the same manner as; Removably fixed to penetrate the sleeve 145 and the boss 144, and selectively integrates the rotary pulleys (124, 244) and the rotating shaft (121, 241) of the pump (120, 240) according to the detachable state It is preferable to comprise a; fitting pin 146 to.

Hereinafter, the herbicide sprayer according to the present invention will be described with reference to the accompanying drawings as follows, and FIG. 3 is a perspective view showing the herbicide sprayer according to the embodiment of the present invention.

As shown, the herbicide sprayer according to an embodiment of the present invention, the drive pulley 110 is integrally mounted to the rear output shaft (A) of the towing vehicle to rotate; A pump 120 having a driven pulley 124 rotating by the drive pulley 110; A driven pulley 124 of the pump 120 and a belt 130 wound around the driving pulley 110 described above; And an idler for selectively idling the driven pulley 124 of the pump 120.

The aforementioned pump 120 may be directly fixed by welding or bolting to the trailer TR or towing vehicle. However, it is preferable to mount to the trailer TR or tow vehicle using the base 146 mentioned later.

Such, the driven pulley 124 of the pump 120 is integrally coupled to the rotation shaft 121 of the pump 120, as shown. Accordingly, the pump 120 is pumped by the drive pulley 110 and the belt 130, and the driven pulley 124 that rotates together when the rear output shaft (A) of the tow vehicle rotates. The pump 120 is connected to a medicine tank and a nozzle unit not shown by a hose (not shown). Therefore, the pump 120 supplies the medicine of the medicine tank to the nozzle while pumping. Of course, the nozzle unit is sprayed by spraying the drug supplied to the farmland.

At this time, it is necessary to provide a base 160 as shown in the pump 120. Such, the base 160 is a plate material is suitable. However, alternatively, a block, an angle, or an angle bracket may be applied. The pump 120 is integrally fixed to one side of the base 160 by welding or bolting. The base 160 to which the pump 120 is fixed is detachably fixed to the trailer TR or the frame F of the tow vehicle by fasteners such as bolts B. FIG. Of course, the base 160 is detached from the frame F when the bolt B is loosened. Therefore, the pump 120 may be stored separately by the detachable base 160.

Here, the above-described idler includes a bearing 142 interposed between the rotary shaft 121 and the driven pulley 124 of the pump 120, as shown in an enlarged view; A boss 144 protruding from the center of one side of the driven pulley 124 in the same body; And a binding member for selectively binding the boss 144 and the rotation shaft 121.

At this time, the binding member is integrally fitted to the rotary shafts 121 and 241 of the pumps 120 and 240, as shown in an enlarged manner, to separate the bearing 142 and the rotary shaft 121, and to be identical to the rotary shaft 121. A rotating sleeve 145; A fitting pin 146 fixedly detachably penetrating through the sleeve 145 and the boss 144 and selectively integrating the driven pulley 124 and the rotating shaft 121 of the pump 120 according to a detachable state; It needs to be configured to include.

As shown in an enlarged scale, the sleeve 145 is integrally fixed to the rotation shaft 121 by a key K. The bearing 142 is fitted into this sleeve 145 and fixed. At this time, the bearing 142 is integrally fixed to the inner ring on the outer peripheral surface of the sleeve 145. The driven pulley 124 is integrally fixed to the outer circumferential surface of the bearing 142. Of course, the bearing 142 is the outer ring is integral with the inner peripheral surface of the driven pulley 124. Such a sleeve 145 and the bearing 142 separates the driven pulley 124 and the rotating shaft 121 from each other. And, the bearing 142 rotatably supports the driven pulley 124 on the sleeve 145. Accordingly, the driven pulley 124 may be idling about the rotation shaft 121.

The boss 144 is disposed outside the rotary shaft 121 while taking the form of enclosing the sleeve 145 as shown by the driven pulley 124 fitted to the rotary shaft 121. At this time, the boss 144 is spaced apart from the sleeve 145 by a gap. Thus, the boss 144 does not rub against the sleeve 145. Such a boss 144, when molding the driven pulley 124, is preferably molded at the same time. If the driven pulley 124 is manufactured by cutting, it is preferable to cut and form the driven pulley 124 simultaneously with the cutting. Alternatively, the boss 144 may be separately formed and coupled to the driven pulley 124 by welding.

The fitting pin 146 is detachably fixed through the boss 144 and the sleeve 145. Of course, as shown in the boss 144 and the sleeve 145, the through-hole H through which the fitting pin 146 is to be formed. The fitting pins 146 line up and then insert the through holes H formed in the boss 144 and the sleeve 145, as shown.

As such, the fitting pin 146 may be applied to the R pin formed in the 'R' shape of the alphabet, as shown. Alternatively, a bolt set consisting of a bolt and nut not shown may be applied. At this time, the bolt is inserted into the through hole (H), the nut is coupled to the lower end of the bolt passing through the through hole (H). However, it is preferable to apply an R pin that is easily removable.

The idler rotates or idles the driven pulley 124 of the pump 120, depending on whether the fitting pin 146 is applied. That is, when the fitting pin 146 is fitted in the through hole (H), the driven pulley 124 forms the same as the sleeve 145 integral with the rotation shaft 121 of the pump 120. Accordingly, the driven pulley 124 pumps the pump 120 while rotating the sleeve 145 and the rotation shaft 121.

In contrast, when the fitting pin 146 is not fitted in the through hole H, the sleeve 145 and the driven pulley 124 are separated. Thus, the driven pulley 124 idles. Of course, the bearing 142 rotates by the driven pulley 124. At this time, since the bearing 142 rotates only the outer ring, the sleeve 145 and the rotation shaft 121 do not rotate. Accordingly, the pump 120 does not perform the pumping operation.

Such idlers are very useful when not spraying drugs. That is, when not spraying the drug, the idler pulley 124 is idling by using an idler. Then, the pump 120 is inoperative and can be protected from the torque of the rear output shaft A while not spraying the medicament.

On the other hand, Figure 4 is a perspective view showing a herbicide sprayer according to another embodiment of the present invention, the herbicide sprayer according to another embodiment is integrally mounted to the rear output shaft (A) of the towing vehicle (T) as shown A rotating drive gear 210; A driven gear 220 that rotates by the drive gear 210 and on which one side the drive pulley 222 is integrally mounted; A pump 240 having a driven pulley 244 rotating by the drive pulley 222 of the driven gear 220; A belt 250 wound around the drive pulley 222 of the driven gear 220 and the driven pulley 244 of the pump 240; And a base 260 to which the driven gear 220 and the pump 240 are integrally mounted.

The driven pulley 244 of the pump 240 described above is integrally coupled to the rotation shaft 241 of the pump 240. Accordingly, the pump 120 is pumped by the rotation of the driven pulley 244, and supplies the medicine of the drug tank not shown to the nozzle unit not shown. At this time, the driven pulley 244 rotates because the rotational force of the driving pulley 222 is transmitted through the belt 250. Of course, the pump 240 has a hose not shown connected to the medicine tank and the nozzle block. Therefore, the medicine of the medicine tank is supplied to the nozzle unit through the hose.

The base 260 is suitably a plate as shown. The driven gear 220 and the pump 240 are fixed to the base plate 260 integrally as shown. At this time, the driven gear 220 is provided with a mounting bracket (M) on the base plate 260, it is rotatably mounted to the mounting bracket (M).

As described above, the base plate 260 is detachably fixed to the trailer TR or the tow vehicle by the bolt B. FIG. That is, when the bolt B is loosened, the base plate 260 is separated from the trailer TR or the tow vehicle. At this time, the pump 240 and the driven gear 220 integrally fixed to the base plate 260 are also separated from the trailer TR or the towing vehicle together with the base plate 260. Therefore, when not spraying the drug, after removing the base plate 260, the pump 240 and the driven gear 220 can be stored separately. Of course, the belt 250 is naturally also stored separately.

In this herbicide sprayer according to another embodiment, it is necessary to install an idler as described in one embodiment. At this time, the idler is preferably installed in the driven pulley 244 of the pump 240.

Here, the sleeve 145 of the idler is fitted and fixed to the rotation shaft 241 of the pump 240, the bearing 142 is interposed between the sleeve 145 and the driven pulley 244. The boss 144 is provided at the front center portion of the driven pulley 244. In addition, the fitting pin 146 is detachably fixed through the boss 144 and the sleeve 241, as shown. Of course, it is obvious that the boss 144 and the sleeve 145 should have a through hole H as described above. The idler rotates or idles the driven pulley 244 by the fitting pin 146. Since the idler is the same as the above-described embodiment, a detailed description of the configuration and operation will be omitted.

Meanwhile, the herbicide atomizer according to another embodiment of the present invention is interposed between the driving gear 210 and the driven gear 220, as shown in an enlarged view of FIG. 4, and the driving force of the driving gear 210 is driven by the driven gear ( At least one electric gear 215 to be transmitted to 220; It is preferably configured to further include.

Thus, the herbicide sprayer equipped with the electric gear 215 is applied when the trailer TR or the towing vehicle is large. That is, the herbicide sprayer without the electric gear 215 is applied when the trailer TR or the towing vehicle is medium or small.

In this case, the electric gear 215 may be configured to have a different gear ratio from the drive gear 210 and the driven gear 220 as shown in an enlarged manner so as to shift the rotational speed of the drive gear 210. The electric gear 215 may be configured as one as shown, but may be configured in plural as necessary.

The herbicide sprayer according to the embodiment of the present invention as described above replaces the driving pulleys 110 and 222 and the driven pulleys 124 and 244 with a sprocket not shown, and instead of the belt 130 with a chain not shown. can do. Since such substitution is easy, detailed description is abbreviate | omitted.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea. Therefore, the shape and structure of each component shown in the embodiment of the present invention can be carried out by modifying, it is natural that the modification of the shape and structure belong to the utility model registration claims of the present invention attached.

The herbicide sprayer according to the present invention as described above, since the base in which the pump and the driven gear are integrally mounted is detachably mounted on the tow vehicle or the trailer, when the herbicide is not sprayed, it can be stored separately from the tow vehicle or the trailer. It works.

In addition, since the idler controls the rotation of the driven pulley, there is an effect that the pump can be selectively operated even when the rear output shaft of the tow vehicle rotates.
