NL1021358C2 - Feed device for planting machine, comprises belt for row of soil blocks containing plants and sensor plate for stopping belt when presence of bottom block is registered - Google Patents

Abstract

A row of loose, pre-sorted blocks of soil containing the plants is formed and then a belt used to carry the blocks is stopped when the bottom block in the row contacts a sensor plate (16), which stops the belt and allows the block to fall to the ground. Once the block has been plated, the process is repeated.

Description

Controlled supply device and planting machine provided with such a supply device. The present invention relates to a plant supply device plant per plant where several plants can be set up at once.

This invention relates to a planting machine for planting plants (e.g. lettuce) that were previously sown in press pots (cubes).

This method is common for such plants. The seeds are sown in mashed blocks with soil or equivalent material in which the plant can root and grow until the plants have reached a certain size. Then they are planted at a greater distance eg. in a greenhouse where they can grow further.

In agriculture and horticulture today it is not possible to wait until the plants are in the ideal condition to be planted. This machine can meet the demand to always be able to plant.

20

With existing plant elements, the block with the plant must always have a certain firmness in order to be able to be planted. However, the current machine can also quickly plant the moister, softer, less-rooted, brittle blocks, as well as the plant blocks.

25

On the conveyor belt fig. 2 the plant blocks follow each other when a block comes at the bottom, it is moved to be planted. The pressure on the plant block is greatest at the bottom of the conveyor belt. This pressure is also uneven eg. due to wet blocks (greater weight) and greater suction of wet blocks on the supply system.

A sensor is placed on the current machine. This sensor gives an impulse if it detects a block at the place where a planting machine can do the planting. Take 1 n 91 q eo 2 to plant it. When the plant block comes against the plate (16), the supply system is stopped by a microswitch. The supply system for supplying other blocks is temporarily switched off until there is a new impulse that the next block may be supplied.

This method is very efficient because all kinds of less ideal blocks can be planted eg. soft, brittle and moist ... plant cubes

Figure 1 shows a complete planting machine including a frame (1) with one mounted plant element (4) (several planting elements per machine are possible).

The frame consists of a supporting part supported by wheels (3) and a standing place (2) for the person who operates the planting machine. The wheels (3) also drive the gear (5) of the plant element. When the planting machine is being driven forward, the plow (6) makes a U-shaped trench in the ground, while the downpipe (7) ensures that the block comes into the ground properly, while the two pressure wheels (8) push the earth against the block. press on. From the box rack (9) where the plant box (10) stands, the cubes of plants are taken to put on the supply system.

Figure 2 shows a perspective drawing of a supply device for press pot plants or similar blocks in which a plant can root and grow. The blocks can be placed one by one on the lifting system or with several together.

Figure 3 shows an endless band of rubber or plastic (12) that runs on both sides of the feed system over a roller (13) and (14). The drive system (14) provides for the drive of the endless belt (12) shown in the drawing. At the end of the supply system there is a plate (16) transversely with respect to the row of plants. The plate (16) is attached to a more upright iron (17) that can move backwards and forwards by means of a pivot point (18). When the blocks move in the direction of the plate (16), the first block comes against the plate (16) which then moves in the same direction to a fixed point, as a result of this movement the top of the flat iron (17) comes up against a circuit breaker (19) which stops the supply of blocks.

In figure 4, a side of the block (11) comes against the plate (16) and pushes the plate (16) away. Figure 4 also shows the drive system (15) which activates the supply system that moves the blocks in the direction of the plate (16). As can be seen in figure 5, the plate (16) is pressed backwards and the supply of the blocks stops.

Figure 6 shows that the first block is moved undamaged to a fall pipe (7) or a place where the block is taken by a system that brings the plant into the ground.

15

Since the system is sensitive, the first block is "loose" (without pressure from the following plant blocks) to be removed for planting with a planting machine. When the block is gone, the sensor indicates that the machine is being restarted.

Claims (1)

The system for quickly planting brittle, soft, breakable blocks with plants that have already been sorted beforehand and manually without breaking them is an important time saving in agriculture and horticulture. The system ensures that the loosely arranged and pre-sorted blocks form a row which is supplied on the supply system and is not compressed at the bottom of the supply system because when the block comes into contact with the plate (16) the supply of the following blocks is interrupted. The supply device is characterized by the supply of blocks, wherein the block at the bottom of the supply system is not compressed by the following plant blocks with plant on the supply system. Because the bottom block comes against the detector and the conveyor belt stops the following plants. When the bottom block is moved, this operation is repeated. The current system does not aim at sorting plant blocks (plants), but it was constructed in such a way that brittle wet plant blocks can be moved with the least possible damage. 1'ftiM 5 R »
