Description

  The present invention relates to a soil disinfecting machine that injects a chemical into soil while traveling in a field.

  As a prior art, the soil disinfector described in Patent Document 1 is exemplified. As shown in FIG. 4, this soil disinfecting machine is connected to a self-propelled drive vehicle such as a tractor so that a machine body 51 movably supported on rolling wheels 53 is towable. The body 51 is equipped with a chemical pump 55 configured to operate in conjunction with the rolling wheels 53 and a chemical tank 58 for storing the chemical. A suction pipe 56 leading to the chemical tank 58 is disposed on the suction port side of the chemical pump 55, and a discharge pipe 57 leading to the discharge port 60 at the tip of the injection sword 59 on the bottom of the machine body is disposed on the discharge port side.

  Conventionally, this type of soil disinfecting machine is mainly used for chloropicrin, and is injected at intervals of about 30 cm by the rotation of the rolling wheel 53 by one chemical pump 55 and one injection knife 59. Further, as the chemical pump 55, a diaphragm pump has been used.

JP 2001-17058 A

  However, in recent years, chloropicrin agents have been shunned due to their strong medicinal properties and irritating odors, and as an alternative, carbam sodium salts have begun to spread. However, this carbam sodium salt must be injected into the soil at intervals of 5 cm, and there is no soil disinfecting machine corresponding to this specification.

  Temporarily, it is conceivable to improve the driving speed of the chemical pump 55 in the conventional soil disinfecting machine. However, if this is done, the chemical pump 55 becomes unreasonable, the operation of the chemical pump 55 becomes unstable, or the life of the chemical pump 55 is increased. May be reduced. In particular, it is preferable to employ a proven diaphragm pump as the chemical pump 55 of the soil disinfecting machine. However, if the driving speed of the diaphragm pump is increased so that the chemical solution is discharged at intervals of 5 cm, excessive movement is forced on the rubber diaphragm built in the diaphragm pump, and the operation of the pump becomes unstable. There is a problem that the diaphragm is easily corroded by a chemical solution and the life is shortened.

In order to solve the above problems, the soil disinfecting machine of the present invention is
For aircraft configured to run freely on the field,
A chemical tank containing the chemical,
A chemical pump for sucking the chemical liquid in the chemical tank;
A pump drive mechanism for operating the chemical pump;
A soil disinfecting machine equipped with an injection means for discharging the chemical liquid discharged from the chemical liquid pump into the soil,
A plurality of the chemical pumps are provided,
The pump drive mechanism is configured to sequentially operate the plurality of chemical pumps,
The injection means is configured to collect the chemical liquid discharged from the plurality of chemical liquid pumps at one place and then send it.

  According to this configuration, since a plurality of chemical pumps are operated in sequence, the driving speed of each chemical pump can be reduced accordingly. As a result, the operation of the chemical pump can be stabilized and the shortening of the life of the chemical pump can be prevented. And since the chemical | medical solution discharged from a several chemical | medical solution pump is collected in one place and it sends to the said injection | pouring means, a chemical | medical solution can be discharged in the soil at a short space | interval.

In the soil disinfector,
A plurality of injection means;
The aspect comprised so that the chemical | medical solution collected in the said one place might be sent to these injection | pouring means is illustrated.

  According to this structure, a chemical | medical solution can be simultaneously inject | poured into a soil in several places by several injection | pouring means.

  According to the soil disinfector according to the present invention, there is an excellent effect that the chemical solution can be discharged into the soil at short intervals.

  1 to 3 show a soil disinfector 1 according to an embodiment of the present invention. The soil disinfecting machine 1 is of a so-called self-propelled type, and includes a machine body 2 that is supported by a front wheel 3 and a rolling wheel 4 so as to be able to travel on a farm field. A prime mover 5 for traveling is mounted on the front of the machine body 2. Thus, the front wheel 3 is driven to rotate. A chemical liquid tank 6 in which the chemical liquid B is placed, a pair of left and right chemical liquid pumps 7 for sucking the chemical liquid B in the chemical liquid tank 6, and a pair of left and right pump drive mechanisms for operating the chemical liquid pumps 7, respectively. 8, a merging portion 9 for merging the chemical liquid B discharged from both the chemical liquid pumps 7, and three injection swords 10 for discharging the chemical liquid B discharged from the merging portion 9 into the soil are mounted. . In each figure, the arrow F indicates the front side of the aircraft.

  As shown in FIGS. 1 and 3, a suction pipe 16 having an open / close valve 15 is inserted into the upper opening of the chemical liquid tank 6, and the suction pipe 16 is branched into two on the way. It is connected to the suction port 7a. The discharge port 7b of each chemical pump 7 is connected to the junction 9 by a first discharge pipe 17, and the junction 9 is connected to each injection knife 10 by a second discharge pipe 18. In this way, the chemical liquid B discharged in order from the pair of chemical liquid pumps 7 is collected in the merging portion 9 and sent from the merging portion 9 to the three injection knives 10. In addition, a pair of recirculation pipes 19 for recirculating excess chemical B to the chemical tank 6 are connected to the junction 9.

  In this example, the chemical pump 7 employs a diaphragm pump. When the push rod 20 is driven to reciprocate up and down, a diaphragm (not shown) incorporated therein is driven. When the push rod 20 is driven downward, the chemical solution B is sucked from the suction port 7a, and when the push rod 20 is driven upward, the chemical solution B is discharged from the discharge port 7b.

  The pump drive mechanism 8 includes a chain transmission mechanism 21 as a speed increasing mechanism for increasing the rotational speed of the rolling wheels 4, a rounded square cam 23 attached to the output shaft 22 of the chain transmission mechanism 21, and one end. A cam follower 24 that follows the cam 23 is provided on the side, and a seesaw lever 25 that reciprocates the push rod 20 of the chemical pump 7 up and down is provided on the other end side. As shown in FIG. 2, the two pump drive mechanisms 8 of this example are mounted with the cams 23 of the two pump drive mechanisms 8 being relatively displaced by 45 ° (in FIG. One of them is indicated by a solid line and the other is indicated by a two-dot chain line.) Thus, the two chemical pumps 7 are alternately operated as the rolling wheels 4 rotate.

  According to the soil disinfecting machine 1 of the present example configured as described above, since the two chemical pumps 7 are operated alternately, the driving speed of each chemical pump 7 can be reduced accordingly. it can. Therefore, the operation of the chemical liquid pump 7 can be stabilized and the shortening of the life of the chemical liquid pump 7 can be prevented. And since the chemical | medical solution B discharged from the two chemical | medical solution pumps 7 is collected in one place and sent to the injection knife 10 as an injection | pouring means, the chemical | medical solution B can be discharged in the soil at a short interval. it can.

  Further, since the chemical solution B collected in one place is configured to be sent to the three injection knives 10, the chemical solution B can be injected into the soil simultaneously in three places.
