Description

Seeder With Better Mobility

The present invention relates to a planter used for sowing various seeds, and more particularly, to a power planter with improved mobility.

In order to more efficiently carry out the seeding work for planting seeds in the field, various types of planters are used. In general, the seeding work is a process of digging soil, planting seeds, covering the soil and suppressing them. When using a seeding machine, such a seeding work is continuously performed at once, thus greatly reducing labor costs and greatly reducing work time. There is an advantage.

These planters can be broadly divided into non-powered, power and tractor types. The non-power type is a seeding work by pushing the seeding machine by manpower, and is widely used for seeding work of about 4-6 rows. The power planter is used for the seeding work of 5-16 rows, and is equipped with a power unit such as an engine for forward and backward movement of the planter because of the weight of the planter. Tractor type planters are devices that are connected to the rear of the tractor and used as a tractor.The number of rows that can be sown at one time is not different from that of a power planter, but the distance between the rows to be sown is wide or the field is too large. It helps to carry out the seeding work more conveniently if it is long or not.

In Korea, many non-powered and power planters are used. As agriculture becomes more modern and per capita cultivation increases, the use of power planters is increasing. An example of such a power planter is disclosed in Korean Patent No. 10-1116051, and FIG. 3 of the registered patent is attached to FIG.

Looking at the structure of a conventional power planter according to the prior art with reference to Figure 1, the drive roller (2) made of stainless steel is provided on the front side so that the soil can be compacted first before seeding. At the rear of the driving roller 2, a plow 6 for seeding the seed is sprayed and a cover plate covering the groove into which the seed is introduced is covered with soil. The upper side of the plow (6) is provided with a seeding part (7) for feeding the seed into the groove, the upper part of the seeding part (7) consists of a seed container or hopper (5) for storing the seed to be sown, The lower part of (7) is composed of a seed input for discharging the seed downward at regular intervals. Behind the cover plate is provided with a suppression roller (3) for compacting the ground once again after the seed is put.

Such a conventional power planter prevents damage to the lower structure such as a ruler and absorbs shocks due to uneven road surface when moving or walking on a field or a truck to move between fields to perform sowing work. On the other hand, in order to be able to make the steering smoothly with less force, and provided with auxiliary wheels provided on both sides of the suppressor roller (see Fig. 2 of the registered patent). These auxiliary wheels may be installed to be driven by power in connection with a power plant such as an engine mounted on a power planter, or may be installed to operate in a non-powered manner without being connected to a power plant.

However, such auxiliary wheels are mounted so that the suppressor rollers do not touch the ground, so that seeding work cannot be performed while the auxiliary wheels are mounted, and thus the auxiliary wheels should be detachably mounted.

The removal or mounting of the auxiliary wheel in the conventional seed drill is carried out with the seed drill lying on the back with the suppressor roller as the rotating shaft so that the auxiliary wheel mounting portion is in the air. This method requires a considerable weight of the seed drill to be rotated back and pulled down by manpower, and the seed drill rotates forward and falls during the removal or installation of the auxiliary wheel, which may cause a safety accident such as damage to the machine or worker injury. There is a risk involved. The handle part of the planter can be designed to be moved forward so that the planter can be stably rotated backwards to be maintained in a stable state. However, the change of the handle position causes inconvenience when the operator holds the handle and controls the planter. can do.

In addition, since the auxiliary wheel is mounted only in the vicinity of the suppressor roller in the conventional planter, when the planter moves, the operator must move the planter while pressing the handle down from the top, that is, the driving roller part while maintaining the state spaced apart from the ground. When moving, it is difficult for the worker to take a comfortable posture and also has a large amount of physical consumption.

2 to 5, the basic structure of the planter with improved mobility according to the present invention is similar to the conventional planter. In other words, the planter 100 according to the present invention is a power type planter, the drive roller 120 is provided to the front side so as to compact the soil before seeding. The driving roller 120 is mainly made of stainless steel in consideration of the strength, corrosion resistance, etc. of the roller, but is not limited thereto.

At the rear of the driving roller 120, a plow (not shown) for digging seeds and a cover plate (not shown) covering the grooves into which the seeds are introduced are disposed in sequence. The upper side of the plow is provided with a seeding unit (not shown) for injecting seeds into the groove, the upper portion of the seeding portion is composed of a seed container or hopper (not shown) for storing the seed to be sown, the lower portion of the seeding portion It consists of a seed input unit (not shown) to be discharged downward at regular intervals. In FIG. 2 to FIG. 7, the seeding part including the plow, the cover plate, and the hopper and the seed input part is omitted from the drawing, which is only to make the characteristic part of the planter with improved mobility according to the present invention more prominent. In addition, the seeding plant according to the present invention also includes these components is the same as the conventional seeding plant.

Behind the cover plate is provided with a suppression roller 130 to chop the ground once again after the seed is put. Suppression roller 130 is also mainly made of stainless steel. The drive roller 120 and the suppressor roller 130 are flange portions 123 configured to protrude radially outwards along the circumference of the cylinders 121 and 131 at left and right ends of the cylindrical rotating bodies 121 and 131. , 133 may be provided. As a result, the rotating bodies 121 and 131 may be spaced apart from the ground by the flanges 123 and 133 on a solid ground such as a road, not a soft ground such as a soil covered field. 131 can be prevented from being damaged by friction with the ground or by collision with a protrusion on the ground (such as gravel on an unpaved road).

The driving roller 120, the suppressor roller 130, and the seeding part are driven by receiving power by the driving device 110 including the engine 111, the transmission 113, and the like. In the illustrated embodiment, the power of the drive device 110 is transmitted directly to the suppressor roller 130 by a chain (not shown) protected by the chain cover 117, and the drive roller 120 is driven through the seeding portion. The power transmission path can be configured differently.

The above components of the planter 100 according to the present invention are all coupled to the planter frame 103 so that they can be supported directly or indirectly by the planter frame 103, the operator planting the rear upper side of the planter 100. (100) A planter handle 107 is used for steering.

2 to 5 again, the rear of the planter 100 according to the present invention in a state in which the suppressor roller 130 located on the rear side of the planter 100 and the main wheel 140 to be described later is lifted from the ground. A planter raising bracket 180 is provided to fix the planter 100.

As described later, when the main mobile wheel 140 is mounted on the seed drill 100 or when the main wheel 120 is removed, the seed drill 100 is lifted up so that the main wheel 140 is spaced apart from the ground. It is convenient and safe to carry out mounting or dismounting of the main wheel 140.

The seed drill raising bracket 180 provided for this, the bracket base 181 coupled to the rear of the seed drill 100 and the bracket frame 185 rotatably coupled to the bracket base 181 in the vertical direction It is made to include. The bracket frame 185 has a bracket support part 183 spaced apart from the bracket base 181.

The bracket supporter 183 is provided to contact the ground in parallel with the ground when the seed drill raising bracket 180 is rotated downward and rearward, and the bracket frame 185 is attached to the ground as shown in FIG. It is preferably arranged such that it can be maintained rotated 1-10 degrees further toward the seeder inside than the vertical line. When viewed only from the side for supporting the load of the planter 100, the planter lifting bracket 180 is configured such that the bracket frame 185 is vertical when the bracket support portion 183 contacts the ground in parallel with the ground. May be advantageous. In this case, however, even when a slight impact is applied from the outside, the bracket frame 185 is rotated upward while leaving the vertical state, whereby the planter 100 whose support by the planter raising bracket 180 disappears. Falling to the ground there is a risk that the planter 100 is damaged or a safety accident occurs to the worker. In order to prevent such a risk, it is safe for the bracket frame 185 to be rotated more than vertically so as to be inclined a little further into the seed drill 100 when the seed drill raising bracket 180 is rotated downward.

However, if the planter raising bracket 180 is inclined to the inside of the planter 100 more than the intended angle when the planter is lowered, this time the planter raising bracket 180 is broken by the load of the planter 100 and the planter ( 100 may fall to the ground.

In order to prevent this risk, the planter lifting bracket 180 may further include a bracket stopper 187 extending downward from the bracket base 181. The bracket stopper 187 is in contact with the upper side of the bracket frame 185 when the planting machine lifting bracket 180 is rotated to the rear lower side and the bracket supporter 183 is in parallel with the ground. Configured to support frame 185. As a result, the bracket frame 185 mentioned above acts to prevent rotation of the planter raising bracket 180 so that the bracket frame 185 is not further rotated beyond the state of the planter being rotated 1 to 10 degrees further toward the inside of the planter than the vertical line with respect to the ground. Will be

On the other hand, when the mounting or detachment operation of the main wheel 140 is completed and the seedling movement or seeding operation is started, it is necessary to rotate the seed drill raising bracket 180 upward. In this case, if the planter raising bracket 180 is simply put up, the planter raising bracket 180 may be unintentionally lowered by an external impact, thereby preventing the seeding operation or the movement of the planter. In order to prevent such a risk, the other end of the fixing spring 190, one end of which is rotatably fixed to one side of the driving device 110, a fixing hole 183a of one side of the bracket support part 183 of the planter raising bracket 180. ) So that the bracket support part 183 is pulled toward the seed drill 100, so that the seed drill raising bracket 180 does not fall. When it is necessary to lower and use the planter raising bracket 180 again, after removing the fixing spring 190 from the bracket support part 183, the planter raising bracket 180 is pushed down by its own weight or by an operator. Descend to the ground. Finally, if the planter raising bracket 180 is to be rotated 1 to 10 degrees further toward the planter than the vertical line with respect to the above-mentioned vertical line to the ground, the worker supports the bracket support portion 183 ), The planter lifting bracket 180 may be disposed at the position by pulling the handle 107 of the planter 100 in a fixed state.

5 and 6, main moving wheel shaft inserting portions 151 are provided at both ends of the rotation shaft 137 of the suppression roller 130 connected to the driving device 110. The main wheel hub insert 151 may be integrally formed with the rotation shaft 137 by being provided to extend outwardly from both ends of the rotation shaft 137 of the suppressor roller 130. As shown in FIG. 6, the main wheel axle insertion part 151 includes a hollow insertion groove formed inward from a longitudinal outer end, that is, from the outermost end. A pair of main wheels 140, each having a main wheel shaft 143, is detachably inserted into the main wheel shaft inserting portion 151, whereby the rotation shaft 137 in the drive device 110. It is possible to rotate by receiving the power transmitted to it again, thereby driving the movement of the planter 100 according to the present invention. The outer diameter of the main wheel 140 is formed to be larger than the outer diameter of the suppressor roller 130, so that the suppressor roller 130 is spaced apart from the ground when the main wheel (140) is mounted.

The combination of the main wheel hub shaft 143 and the main wheel hub insertion unit 151 may be achieved in various ways. However, since the rotational power from the driving device 110 must be transmitted to the main wheel 140 through the main wheel wheel 143 through the rotation shaft 137 and the main wheel wheel inserting portion 151, The main wheel hub shaft 143 and the main wheel hub insertion portion 151 may be detachably coupled to each other without rotation.

Accordingly, the longitudinal cross-section of the main wheel hub shaft 143 and the main wheel hub insertion portion 151 is made of one selected from the shape of a square (A), hexagon (B) or spline (C) as shown in FIG. Can be. All of these shapes are suitable for transmission of power, and may be appropriately selected in consideration of the size of power to be transmitted and the detachment frequency of the main wheel 140. For example, while the spline cross section can deliver the greatest power, there is a disadvantage that the coupling is solid and the detachment is rather inconvenient.

In order to make the removal relatively easy, the main wheel hub 143 and the main wheel hub insertion unit 151 are configured such that a clearance gap of 0.2-0.4 mm is formed in all directions on the basis of the state located at the common center thereof. It is desirable to be.

Alternatively, longitudinal cross-sections of the main wheel axle 143 and the main wheel axle insert 151 may be formed in a circular shape. However, in this case, a separate coupling means for additionally rotating the main wheel hub shaft 143 and the main wheel hub insertion unit 151 to be non-rotating with each other is additionally required. For example, the coupling illustrated in FIG. Coupling by the pin 157 is possible. In this case, since the coupling pin 157 is coupled, the clearance gap between the main wheel hub shaft 143 and the main wheel hub insertion unit 151 may be set slightly more than the above-mentioned value. Therefore, it is relatively easy to remove the main wheel axle 143 from the main wheel axle insertion part 151 in a state where the coupling pin 157 is removed.

Referring to FIG. 8, auxiliary moving wheel mounting brackets 170 are provided near both ends of the driving roller 120, and the auxiliary moving wheel mounting brackets 170 have auxiliary moving wheel shafts 163 of the auxiliary moving wheels 160. There is provided an auxiliary moving wheel shaft insertion unit (173) that can be inserted.

The auxiliary moving wheel mounting bracket 170 may be fixed to the side front lower side of the planter frame 103 on which the drive roller 130 is mounted in the planter 100 of the present invention. The auxiliary moving wheel mounting bracket 170 is provided with an auxiliary moving wheel shaft insert 177 having a cylindrical hollow portion 177a. The cylindrical hollow portion 177a is formed such that both ends in the longitudinal direction thereof are opened, or at least the seed end side in which the auxiliary moving wheel shaft 163 is inserted is opened.

In the illustrated embodiment, the auxiliary moving wheel mounting bracket 170 is an upper surface 171 is fixed to the planter frame 103 and an inner surface 172 extending downward from the left and right or the inner and outer ends of the upper portion, respectively; The auxiliary moving wheel shaft inserting portion 177 having the outer side surface 173 and having the cylindrical hollow portion 177a is fixed at both ends to the inner side 172 and the outer side 173 so as not to be rotatable. To be combined.

The auxiliary movement wheel shaft 163 of the auxiliary movement wheel 160 is rotatably coupled to the cylindrical hollow portion 177a of the auxiliary movement wheel shaft insertion portion 177, wherein the cylindrical hollow portion 177a is cylindrical It acts as a journal bearing.

In the auxiliary moving wheel 160, the auxiliary moving wheel shaft 163 and the cylindrical hollow portion 177a are in sliding contact with each other, and when the seeding machine 100 moves, the auxiliary moving wheel (eg, by the load of the seeding machine 100). Due to the force applied to the 160, the auxiliary movement wheel 160 may move little by little in the axial direction to be separated from the auxiliary movement wheel shaft insertion unit 177. In order to prevent the departure of the auxiliary wheels 160, it is preferable that a forward camber angle of 0.5-1 ° is formed on the auxiliary wheels 160. The forward camber angle refers to the camber angle when the distance between the upper ends of the left and right auxiliary moving wheels 160 is greater than the distance between the lower ends. To this end, when the auxiliary shifting wheel shaft inserting portion 177 is fixed to the seed drill frame 103, the auxiliary shifting wheel shaft inserting portion 177 may be formed such that the forward camber angle is formed on the auxiliary shifting wheel 160. It should be fixed by setting the direction of.

 The outer diameter of the auxiliary moving wheel 160 is formed in a size such that the driving roller 120 is spaced apart from the ground and is not in contact with the ground when the auxiliary moving wheel 160 is mounted on the auxiliary moving wheel mounting bracket 170. do.

In the illustrated embodiment, the auxiliary movement wheel 160 is configured to be driven in a non-powered manner without being connected to the driving device 110, but is driven in conjunction with the driving roller 130 driven by the driving device 110. It may also be configured to rotate.

Although the planting apparatus according to the present invention has been described in detail above with reference to the accompanying drawings, this is merely illustrative and should not be construed as limiting the scope of the present invention. It should be noted that it is determined by the description.
