Problems solved by technology

For this reason the deep fertilization device that is used for paddy field is in order to overcome this problem, utilizes as publication number CN1742532A patent document, patent name: boat type deep fertilization ditch opener, it is done wide ditch knife, and in order to prevent that thin mud stops up fertilization opening, There will be a mud shield to prevent the mud from clogging the fertilization opening. If the depth adjustment method described in the former is used in the latter, since the paddy field opener is heavy, the heavy opener needs to be removed for each adjustment. , then adjust, and finally reinstall, the whole process requires at least two people, so the adjustment process is labor-intensive, and this depth adjustment method is not suitable for paddy field depth adjustment
[0004] The current deep fertilization equipment for paddy fields has seriously affected the utilization rate of fertilization fertilizers for paddy fields because of the inability to adjust the fertilization depth or the adjustment of the fertilization depth is too complicated.

Embodiment 1

[0031] Such as figure 1 As shown, a ditch opener for deep fertilization in a paddy field includes a ditching shovel 1, a cover plate 2, a front vertical plate 3, a rear vertical plate 4, and a mudguard 5 that penetrates up and down. The ditching shovel 1 and the mudguard 5 correspond connection, the cross section of the mudguard 5 is U-shaped, and the opening is fixedly connected with the rear vertical plate 4 to form a hollow structure that penetrates up and down. The top end of the mudguard 5 is covered with a cover plate 2, and the cover plate 2 is provided with a The fertilizer hole 6 and the ditch opener installation hole 7, the lower fertilizer hole 6 is connected with the fertilizer discharger,

[0032] Such as Figure 2-3 As shown, the left and right inner walls of the mudguard 5 are provided with fertilizer guide plates 8, the top of the fertilizer guide plate 8 is hinged on the inner wall of the mud guard 5, and the back of the fertilizer guide plate 8 is pushed to ...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the first connection hole and the second connection hole are one, and both the first connection hole and the second connection hole are elongated holes extending along the vertical direction, and the two elongated holes Connections are secured with bolts and nuts.

Embodiment 3

[0041] The difference between this embodiment and the above-mentioned embodiment is that: the connecting holes are arranged on the back of the ditching shovel 1, the connecting holes are arranged in a vertical direction and there are a plurality of them, the fixing rod 33 is fixedly arranged on the mudguard 5, The trenching shovel 1 is fixed at different depths by fixing the fixing rods 33 in the connection holes at different positions, and there may be multiple fixing rods 33 to strengthen the connection.

[0042] Working principle of the present invention: through the depth adjustment structure 10 provided between the ditching shovel 1 and the mudguard 5, connecting holes are respectively arranged along the vertical direction on the ditching shovel 1 and the mudguard 5, and through the connection holes Pierce the fixed rod 33 or provide a connecting hole on one of the ditching shovel 1 and the mudguard 5, and set the fixing rod 33 on the other, so that the ditching shovel 1 i...

Abstract

The invention discloses a paddy field deep fertilization furrow opener. The paddy field deep fertilization furrow opener comprises a furrower and an up-and-down through mud guard, wherein the furrower is connected with the mud guard. The furrow opener further comprises a depth adjusting structure, wherein the depth adjusting structure comprises connecting holes formed on the back of the furrower and / or the mud guard and fixing rods located in the connecting holes to fix the furrower and the mud guard. In the adjusting process, the depth of the furrower is adjusted after a bolt is loosened without entirely dismounting; the adjusting is simple and convenient, the structure is simple, the slime can be effectively prevented from blocking fertilization holes, the deep fertilization demand in the paddy field is satisfied, the fertilizer use rate is effectively improved, and the paddy field deep fertilization furrow opener disclosed by the invention is wide in market application and spread prospect.

Description

technical field [0001] The invention relates to a fertilization device for assisting fertilization, in particular to a ditch opener for deep fertilization in paddy fields. Background technique [0002] my country is the world's largest consumer of chemical fertilizers, but the utilization rate of chemical fertilizers is low. Studies have shown that deep application of fertilizers is one of the important ways to improve the utilization rate of fertilizers. For example, deep application of ammonium bicarbonate and urea to the soil layer 6-10 cm below the surface can increase the utilization rate of nitrogen fertilizer by 115% and 35% compared with surface application. . At present, the deep application of fertilizers in dry land in my country has been widely used. It can be seen from this that fertilizers should be applied to different depths according to needs to improve the utilization rate of fertilizers. However, the current paddy field openers themselves do not have heig...
